WHERE TO INSTALL THE WATER SOFTENER

Review the following points before you choose a place

1.Place as close as possible but always after, the pressure tank (well water) or water meter (city water). See Fig. 3.

2.Place as close as possible to a water drain such as a floor drain, laundry tub, sump or standpipe. See Fig. 3.

3.Connect to the house main water pipe BEFORE THE WATER HEATER. See Fig. 3. Temperature of water going through the softener must not be more than 120??F (49??C). Hot water will damage inner softener parts. To reduce the risk of hot water backup, piping between the softener and water heater should be as long of a run as possible.

4.Keep outside faucets on hard water to save soft water and salt. See Fig. 3.

5.Do not install in a place where the softener could freeze. Damage caused by freezing voids the war- ranty by Sears Brands Management Corporation.

to put your softener.

6.Put the softener in a place where water damage is least likely to occur if it develops a leak. Sears or the manufacturer will not repair or pay for water damage.

7.A grounded, 120V electrical outlet is needed within 10 feet of the softener. See Fig. 3. This is to plug in the transformer. The softener has a 10 foot power cable. Be sure the outlet and transformer are in an inside place, to protect from wet weather. Use a continuously "live" outlet, which cannot be acci- dentally switched off.

8.When installing in an outside location, you must take the steps necessary to assure the softener, installa- tion plumbing, and wiring, are protected from the

elements, direct sunlight, contamination, vandalism, etc.

Run drain tubing to laundry tub or p-trap inside home, if possible. Otherwise, run to a dry well.

PIPE,FITTINGS,OTHER MATERIALS NEEDED

You must first decide how to run "in" and "out" pipes to the softener. Look at your house main water pipe at the point you will connect the softener. Is the pipe soldered copper, glued plastic, or threaded galvanized or brass?

What is the pipe size? What kind of pipe and fittings is it easiest for you to work with, and what tools do you have?

Now look at the common plans for "in" and "out" piping on soldered copper. See Fig. 6. Use it as a guide to plan what materials you will need. Get all the materials you will need before you start.

Use Fig. 5 to make a plan drawing for your specific installation. "In" and "out" fittings included with the soften- er are 1" NPT threaded adaptors. You should maintain the same, or larger, pipe size as the water supply pipe, up to the softener inlet and outlet. Use copper, brass, galvanized or PVC plastic pipe and fittings for the "in" and "out" pipes. Be sure to check local codes.

Note: If converting from galvanized to copper pipe use approved dielectric insulating connectors.

ALWAYS install the bypass valve (that is included with the unit) or a three valve bypass. See Fig. 9 to13. Bypass valves let you turn off water to the softener if needed for repairs, but still have water in the house pipes.

Drain tubing (3/8" inside diameter), is needed for the valve and salt tank drains. See Fig. 16. If a rigid valve drain is needed to comply with plumbing codes, you can buy the parts needed (see Fig. 16) to change the soften- er to a 1/2 inch minimum copper tubing drain.

*NOTE:

For plumbing connection, buy 2 sweat adaptors and plumb directly to the inlet - outlet adaptors. Threads on the inlet - outlet adaptors are 1" NPT.

CAUTION:

DO ALL SOLDERING BEFORE CONNECTING SWEAT ADAP-

TORS TO INLET-OUTLET ADAPTORS OR BYPASS VALVE.

BEFORE INSTALLING CHECKS & TESTS

Your water supply needs to be checked for chemical analysis, water pressure and water flow rate. To accom- plish this, complete the following steps:

Check Water's Chemical Analysis: Sears sells a com- plete line of water treating equipment to correct various water problems. To be sure you have the proper type and size equipment, You must have your water tested. Your Sears store can give you a water test results for hardness, iron and acidity, and tell you what equipment you need. Simply take at least a 4 oz. sample of your water to Sears, and they will test it while you wait. If you need help to get your water tested, or if you have other questions about your water, ask at your Sears store.

NOTE: Add these readings to the Facts and Figure table on page 3.

Check Your Water Pressure: For your softener to work right, a water pressure of no lower than 20 pounds per square inch (psi) is needed in the house water pipes. The highest pressure allowed in the water pipes is 125 psi. If pressure is over 125 psi, buy and install a pres-

sure reducing valve in the water inlet pipe to the soften- er.

NOTE: If water pressure during the day is 100 psi or more, pressure during the night may go over 125 psL

Adding a pressure reducing valve may reduce the flow.

NOTE: Add these readings to the Facts and Figure table on page 3.

If you have a well water system, look at the pressure gauge to find the water pressure. Call your local water department if you have city water. They will tell you what the water pressure is where you live.

NOTE: Add these readings to the Facts and Figure table on page 3.

Check your water flow rate: A water flow of at least 3 gallons per minute is needed. A lower flow will keep your softener from working as well as it should. Complete the following steps to make an easy check of your flow rate.

1.Fully open two cold water faucets close to the point water enters the house.

2.With both faucets open, fill a gallon container at one faucet while looking at a watch or clock to see how many seconds it takes.

3.Empty the container and go to the second faucet (be sure BOTH faucets are still on). Fill the gallon container at the second faucet and see how many seconds it takes.

4.Turn off both faucets. Now add the number of seconds it took to fill the container at both faucets.

5.A total of 90 seconds, or less, means the system flow rate is good.

NOTE: Add these readings to the Facts and Figure table on page 3.

NOTE: Codes in the state of Massachusetts require installation by a licensed plumber. For installation, use plumbing code 248CMR of the Commonwealth of Massachusetts.

ASSEMBLE INLET OUTLET ADAPTORS,

OR SINGLE BYPASS VALVE

Complete the following steps to assemble the adaptors or bypass valve.

1.Close the shutoff valve on the house main water pipe, near the water meter or pressure tank, to turn off the water. See Fig. 7.

2.Shut off the gas or electric supply to the water heater. See Fig. 7.

3.Open the highest and lowest water faucets in your

house. This will let water drain from the pipes. Close faucets after water has drained.

4.Remove the main cover. Remove the salt hole cover first and then pull outward on the two tabs to release main cover. See Fig. 8.

Set both covers aside so they will not get scratched or bro- ken.

INSTALL SEARS BYPASS VALVE AND / OR THE

INLET OUTLET THREADED ADAPTORS

NOTE: If you will not install the bypass valve because you will have a three (3) valve bypass, skip steps 6 & 7, but do steps 5 and 8.

5.Visually check and remove any foreign materials from the valve inlet and outlet ports. See Fig. 9. Carefully remove the two large plastic clips (you will use them). Check to be sure the turbine and turbine support are firmly in place. See Fig. 10.

BYPASS VALVE:

6.Put a light coating of silicone grease on the o-ring seals and slide onto the bypass valve.

7.Push the bypass valve into the softener valve as far as it will go. Snap the two large holding clips into place, from the top down as shown. See Fig. 11.

CAUTION: Be sure the clips snap firmly into place so the bypass valve will not pull out. See Fig. 11.

INLET AND OUTLET THREADED ADAPTORS:

8.Put a light coating of silicone grease on the o-ring seals and slide into the threaded adaptors. Push the adaptors into the valve inlet and outlet ports, or bypass valve ports, as far as they will go. Both adaptors are the same and fit either port. Snap the two large holding clips into place, as shown. See Fig. 11.

CAUTION: Be sure the clips snap firmly into place so the tubes will not pull out. See Fig. 11.

POSITION SOFTENER INTO PLACE

Complete the following steps to position the softener.

1.Grip under the ridge on the salt tank sidewall.

2.Carefully rock back and forth into position.

3.Move the softener into position.

4.Place on a level and smooth surface. If needed, put a piece of 3/4" plywood, at least 17" x 20", under the tank. Then put spacers under the plywood to level the softener. See Fig. 14.

NOTE: Do not put shims or spacers directly under the tank, without the plywood. The weight of the sof- tener, when full of salt and water, may cause the tank to puncture or break at the shim or spacer.

MOVE SOFTENER INTO PLACE

Grip under ridge to move softener.

CONNECT THE SOFTENER

Refer to your plan drawing. See Fig. 5.

Measure, cut (thread if needed) and put all pipe and fit- tings together up to the main water pipe, or to the bypass valve(s) you installed in the previous step.

CAUTION: Never solder fittings while connected to nonmetallic parts. Wait until soldered pipe has cooled before connection. See Fig. 15.

CAUTION: Be careful when putting pipe fittings together. Do not cross thread, and do not overtight-

en.

1.Cut pipe to correct length.

2.Solder (WHEN COOL, do Step 3).

3.Put threaded adaptor

CONNECT THE VALVE DRAIN HOSE

Take a length of 3/8" inside diameter drain tubing and attach one end to the drain fitting. See Fig. 16. Use a tube clamp to hold it in place. Put the other end of the tubing over a floor drain, into a laundry tub, standpipe, or other suitable drain. Check your local codes.

Leave an air gap of about 1-1/2" between the end of the hose and the drain. This gap is needed so you don'tget a backflow of sewer water into the softener. Do not put the end of the hose into the drain or con- nect without the air gap.

Place and support the hose so it does not kink or have sharp bends. Secure the hose end so water pressure does not cause the hose to "whip". Tie or wire it in place. Do not pinch the hose shut. The softener will not work if this drain hose is pinched, plugged, closed or restricted in any way. Direct drain flow

down into drain from drain line as flow could possibly over shoot the drain cover.

Keep the hose lower than the drain fitting. In some homes, to get to a drain you must raise the hose and run it overhead. If you need an overhead drain, do not raise the hose more than 8'above the floor. A copper drain tube is best to use.

COPPER DRAIN TUBE: Local plumbing codes may require the use a copper valve drain tube. A copper

Grommet Tube

_, Adapto_

tube is also best to use for an overhead drain. Use a copper drain tube if the softener is installed outside, or in the sunlight. Heat from the sun can soften, flatten and close up some kinds of tubes.

To adapt a copper drain tube to the softener, buy a compression fitting (1/4" female pipe threads x 1/2" O.D. tube) and tubing from your local hardware store.

CONNECT SALT TANK OVERFLOW TUBING

1.Locate the rubber grommet, tube adaptor and tube clamp (see Fig. 16) that are in the parts bag.

2.Push the grommet into the hole in the salt tank wall so half is inside and half is outside.

3.Push the bigger end of the tube adaptor into the grommet.

4.Push one end of a length of 3/8" I.D. tubing onto the tube adaptor, using the tube clamp to hold it in place.

5.Put the other end of the tubing over the floor drain.

IMPORTANT: Overflow water must run downward through the tubing. Do not raise the tubing higher than the grommet and tube adaptor. See Fig. 16. IMPORTANT: Do not connect to the valve drain hose you installed in step 1. Both drains must have a separate hose or tube.

NOTE: Overflow drain tubing is available from

Sears. See parts list in back of manual.

LEAK TEST

To check for leaks, complete the following steps:

CAUTION: To avoid water or air pressure dam- age to softener inner parts, and to flush pipe chips or other residue from the water pipes, be

sure to do the following steps exactly asShu_ instructed.

HOUSE MAIN WATER

SHUTOFF VALVES

1.Fully open two cold, soft water faucets near the softener.

2.Look at the pictures in Fig. 18 and 19 to deter- mine your kind of bypass valve(s). Place bypass valve(s) in "bypass" position. On a single valve, slide the stem inward to bypass. On a three (3) valve system, close the inlet and outlet valves and open the bypass valve.

3.Fully open the house main water pipe shutoff

valve. Observe steady water flow from both open faucets.

4.Place bypass valve(s) in SERVICE EXACTLY as follows: Keep soft water faucets open.

a. Single Bypass Valve: Slowly, slide pull the valve stem outward toward service, pausing sev- eral times to allow the softener to pressurize slow- ly.

b. Three Valve Bypass: Fully close the bypass valve and open the outlet valve. Slowly, open the inlet valve, pausing several times to allow the sof- tener to pressurize slowly.

5.After about three minutes, open a hot water faucet for about one minute, or until all air is expelled, then close.

6.Close both cold water faucets.

7.Check your plumbing work for leaks and fix right

away if any are found. Be sure to observe previ- ous caution notes.

NOTE: If this procedure is performed on a new softener, water coming from the taps may initial- ly be discolored. This normally occurs the first time water runs through the resin bed. The dis- colored water is not harmful, and the discol- oration will not last more than a few minutes.

INSTALLGROUNDINGCLAMPBETWEEN

THESOFTENERINAND OUT PIPES

The house cold water pipe (iron or copper) is often used to ground all electrical outlets in the home. Outlets are grounded to protect you from shock when you touch any electric appliance plugged into the out- let. If you installed the single bypass valve, the cold water pipe ground is broken. See Fig. 20 and 21.

IMPORTANT: Be sure the cold water pipe has direct metal to metal contact all the way to the ground. Plastic, rubber or other electrically insulat- ing parts such as hoses, fittings, washers or gas- kets can break the direct metal to metal contact. Also check the water meter (city water) or the well pump. Install #4 copper jumper wires, clamped tightly on both ends, across insulated parts. See Fig. 21.

To restore the ground, take the ground clamp kit that is in the parts bag. Install across the inlet and outlet cop- per tubes. See Fig. 20. Be sure good contact is made between the pipe and the clamps.

ELECTRICAL POWER OUTLET FOR

YOUR SOFTENER

The softener works on 24 volt, 60 Hz electric power. The included transformer changes standard 120 volt AC house power to 24 volts. You must plug the trans- former into a grounded, 120 volt outlet only. Be sure the outlet is always "live" so someone cannot turn it off by mistake. See Fig. 22.

NOTE: The included transformer is made for inside

use only. Be sure the electrical outlet you plug the transformer into is inside, to protect from weather.

NOTE: Each press of the UP or DOWN button changes the display by 1 between 1 and 25. Between 25 and the highest number, the display changes 5 at a time (25, 30, 35, etc.) Holding the

UP or DOWN button in changes the display twice each second.

SET REGENERATION TIME

To complete setting the regeneration time, complete the following steps:

1.Press the SELECT button to display the words SET RECHARGE TIME and a flashing 2:00 AM.

2.At the 2:00 AM recharge time setting, the softener begins regeneration (see pages 25 - 27) at 2:00 AM. This is a good time in most households because water is not being used. If a different recharge time setting would be better for your household, complete the following step.

3.Press the UP or DOWN buttons to set the desired recharge starting hour. Be sure to observe the AM- PM as you did when setting the present time of day.

Note: Each press of the UP or DOWN buttons changes the display one hour. Holding the but- tons in changes the display twice each second.

SET SALT LEVEL

To set the salt level, complete the following steps:

1.Press the SELECT button to display SET SALT LEVEL and a flashing 0 (zero). See page 21, for instructions on adding salt to the salt storage tank. The face plate timer has a salt monitor with an indi-

cator light to remind you to add salt to the storage tank.

NOTE:You must set salt level each time salt is added to the water softener.

2.To set this monitor system, lift the salt hole cover and level the salt in the storage tank. The salt level decal, on the brinewell inside the tank, has numbers from 0 to 8. Observe the highest number the leveled salt is at, or closest to. Press the UP or DOWN but- tons until the number corresponds with the salt level number. At level 2 or below, the indicator LED will flash. If you wish to turn this feature off, press the DOWN button past 0, and the word "OFF" flashes in the display.

3.Press the SELECT button once again, to complete initial programming, and the current time of day will show in the display.

SANITIZE THE WATER SOFTENER

Care is taken at the factory to keep your water softener clean and sanitary. Materials used to make the softener will not infect or contaminate your water supply, or cause bacteria to form or grow. However, during shipping, storage, installing and operating, bacteria could get into the softener.

SANITIZE YOUR WATER SOFTENER AS FOLLOWS:

1.Be certain the bypass valve is pulled out to

"service" position.

2.Lift the salt hole cover and using a pail add up to 3 gallons of water to the salt storage tank.

3.Remove the brine well cover (Fig. 28) and pour about 3/4 ounce, or 1 to 2 tablespoons, of common 5.25% 1, unscent- ed, household bleach (Clorox, Linco, BoPeep, White Sail, Eagle, etc.) in the softener brinewell. Replace the brinewell cover.

4.Press the REGENERATION button and hold for 3 seconds to start a recharge. This first recharge does several things.

???It draws the bleach into and through the softener to sani- tize it.

???It fills the salt tank to the water level needed.

???It gets all the air out of the resin tank.

???It prepares the resin bed (see page 25) for service and flushes residual chlorine from the softener.

NOTE: This recharge takes about 2-1/2 to 2-3/4 hours, depending on the salt type setting.

NOTE: During a recharge the water softener bypasses raw water to the home. You will not get salty water or affect the regeneration cycle if water is used at this time.

You can sanitize the softener with or without salt in the storage tank.

1Recommended by the Water Quality Association.

On some water supplies, the water softener may need peri- odic disinfecting.

Your new Sears softener is now softening the water for your household needs. However, your WATER HEATER is filled with hard water. To have fully soft water right away, you can drain the water heater so it refills with soft water. If you don't drain the water heater, it will take a few days before you have fully soft water.

To drain the water heater, open a hot water faucet and let it run until the water runs cold. Then close the faucet.

NOTE: If this procedure is performed on a new softener, water coming from the taps may initially be discolored.

This normally occurs the first time water runs through the resin bed. The discolored water is not harmful, and the discoloration will not last more than a few minutes.

If you choose Potassium Chloride (KCl) as a regenerant,

following these suggestions will help give you years of maintenance free service.

1.Place only one bag of KCl in your softener at a time (the salt storage tank should contain no more than 60 pounds of KCl at any one time).

2.A softener using KCl should not be placed in areas with temperature fluctuations and high humidity (KCl will harden in these environments and may make the softener inoperable).

3.Check the brine tank and brine well (black tube in salt

storage tank) monthly. If hardening is present, pour small amounts of warm water on hardened areas until

they loosen.

4.If your softener does not have a KCl salt setting you must increase your hardness setting by 25% to ensure continuous soft water as in example below.

FIG.29

Persons who are on sodium restricted diets should con- sider the added sodium as part of their overall sodium intake. For example, if your water supply is 15 grains hard, and you drank 3 quarts of softened water you would consume 335 milligrams of sodium. That is equivalent to eating 2-1/2 slices of white bread.

WATER SOFTENING SALT WITH IRON

REMOVING ADDITIVES

Some salts have an additive to help the softener handle iron in the water supply. These salts may be used if your water supply has a high iron content. It is recom- mended to use Sears Resin Bed Cleaner (refer to the Parts List in back of manual for part number) for period- ic treatments to keep your resin bed clean. This is avail- able at your local Sears store.

Persons who are concerned about their drinking water

should consider a Kenmore Drinking Water System that will remove or reduce in excess of 90% of the sodium

and other drinking water contaminants.

The face plate timer has a low salt monitor with an indi- cator light to remind you to add salt to the storage tank.

To set this monitor system:

1.Lift the salt hole cover and level the salt in the storage tank.

2.The salt level decal, on the brinewell inside the tank, has numbers from 0 to 8. Observe the number the lev- eled salt is at or closest to.

3.Press SELECT once to get to the Set Salt Level screen. Now press the UP or DOWN buttons until the number corresponds with the salt level number. At level 2 or below, the indicator LED will flash. If you wish to turn this feature off, press the DOWN button past 0, and the word "OFF" flashes in the display.

NOTE: You must set salt level each time salt is added to the water softener.

CaliforniaEfficiency Requirement

Your Kenmore Water Softener has a "High Efficiency" feature with an "ON" or "OFF" setting. This softener setting is shipped in the "OFF" position, which utilizes the maximum rated capacity while most often achiev- ing maximum salt efficiencies. When installing this unit in the State of California, you MUST turn this setting to the "ON" position which may initiate more frequent recharges, however it will operate at 4000 grains per pound of salt or higher.

EFFICIENCY MODE

When this feature is ON, the water softener will operate at salt efficiencies of 4000 grains of hardness per pound of salt or higher. (May recharge more often using smaller salt dosage and less water). Installations in the state of

California require this setting to be turned ON. This softener is shipped in the OFF setting.

To turn this setting ON:

1.Press and hold the SELECT button until the display shows 000--.

2.Then press (do not hold) the SELECT button again. Use the UP arrow to turn ON.

3.Press SELECT to enter and return to normal running

screen. The efficiency icon will only be displayed when this feature is ON.

PROGRAM MEMORY

If electrical power to the softener goes off, the time dis- play is blank but the face plate timer keeps the correct time for about 6 hours. When electrical power comes on again, you have to reset the present time only if the dis- play is flashing. The HARDNESS, RECHARGE TIME and SALT LEVEL never require resetting unless a change is desired. Even if the timer is incorrect after a long power outage, the softener works as it should to keep your water soft, however, regenerations may occur at the wrong time of day until you reset the timer to the correct time of day.

ERROR CODE

An error code could appear in the face plate display if a problem occurs in the softener electronics. Turn to the

Troubleshooting section to resolve the problem and/or call the Kenmore Water Line number listed below.

SOFT WATER SERVICE AND REGENERATION

SERVICE

When the softener is giving you soft water, it is called "Service". See Fig. 36. During service, hard water comes from the house main water pipe into the soften- er. Inside the softener resin tank is a bed made up of thousands of tiny, plastic resin beads. As hard water passes through the bed, each bead attracts and holds the hardness minerals. This is called ion exchanging. Water without the hardness minerals (soft water) flows out of the softener and into the house soft water pipes. After a period of time, the resin beads hold all of the hardness minerals they can, and cleaning with salt brine is needed. This cleaning is called regeneration or recharge. Regeneration is started at 2:00 a.m. by the electronic timer. It takes place in 5 stages or cycles.

These are: 1. Fill

2.Brining

3.Brine Rinse

4.Backwash

5.Fast Rinse

REGENERATION

The five steps listed above are described in detail over the next several pages.

FILL: Salt, dissolved in water, is called brine. Brine is needed to clean the hardness minerals from the resin beads. To make the brine, water flows into the salt stor- age area during the fill stage. See Fig. 37. Fill cycle length depends on how much soft water making capaci- ty you have used since the last regeneration. As you use more water, fill time increases so more brine is

made. The greater amount of brine cleans more hard- ness minerals from the resin bed.

SOFT WATER SERVICE AND REGENERATION

BRINING: During brining, the brine is moved from the salt storage area, into the resin tank. See Fig. 38. Inside the resin tank, brine cleans hardness minerals from the resin beads and they are discharged out the drain. How much brine is needed to clean the resin depends on:

???The amount of water used between regenerations.

???The amount of resin in the softener,

???How fast the brine goes through the bed.

The nozzle and venturi makes suction to take brine from the salt tank and put it into the resin tank. They keep the brine flow down to a very slow rate to get the best resin cleaning with the least salt.

BRINE RINSE: After all of the brine is moved into the resin tank, the brine valve closes. Water keeps flowing the same way it did during brining except the brine flow has stopped. Hardness minerals and brine flush from the resin tank to the drain. Brining and brine rinse together vary in the length of time they take, relative to the fill cycle length. See Fig. 38.

BACKWASH: During backwash, water flows UP through the resin tank at a fast rate to flush iron miner- als, dirt and sediments from the bed and to the drain. The bed lifts and expands for good cleaning. See Fig. 39.

FAST RINSE: Backwash is followed by a fast flow of water down through the resin tank. The fast flow packs the resin bed and gets it ready for return to service. See Fig. 40.

After fast rinse, the softener returns to service. Hard water goes into the resin tank where the resin bed again takes out the hardness minerals. Soft water goes to the house soft water pipes.

SOFT WATER SERVICE AND REGENERATION

AUTOMATIC BYPASS

During the brining, brine rinse and backwash cycles of regeneration, HARD water goes through the softener valve and to the house pipes. If a faucet is opened, hard water is there for your needs. However, you should not use hot water, if possible, because the water heater will refill with hard water. The softener, as factory pro- grammed, regenerates from 2:00 AM to about 4:20 AM, a time when not much water is used.

If you start your day prior to 4 AM, you may need to change the recharge starting time. Set the recharge time to 12:00 AM or 1:00 AM. Then regeneration will start and end that much earlier and your water heater will not refill with hard water if a hot faucet is opened.

ELECTRONICS

Two main parts of the softener's electronics are: a WATER METER, and a COMPUTER.

???WATER METER The water meter is in the softener valve outlet. As water flows through the meter, it sends electric pulses to the computer. The computer changes the puls- es to a measure in gallons of water.

???COMPUTER The computer is part of the faceplate timer circuit board. It is programmed to know the softener's capacity (how many grains of hardness minerals it will take out of the water before a regeneration is needed). When starting the softener, you set it for the grains per gallon (gpg) hardness of the water.

To find a regeneration pattern best for your needs, the computer uses:

(1)water usage from the meter

(2)hardness setting

(3)softener capacity

(4)time since the last regeneration.

l-' l

FIG. 40

The computer always adjusts this pattern to your water using habits. It works toward providing you with soft water for the longest time and at the most efficient salt usage.

Softening capacity is used as hard water goes through the softener and hardness minerals are removed. When the computer determines that only enough capacity remains to provide soft water up to the next regenera- tion starting time (2:00 AM, or as otherwise set) it will schedule a regeneration. When the regeneration

begins, RECHARGE NOW flashes in the display during the regeneration.

SALT BRIDGE

Sometimes, a hard crust or salt bridge forms in the salt storage tank. It is usually caused by high humidity or the wrong kind of salt. When the salt bridges, an empty space forms between the water and salt. Then salt will not dissolve (melt) in the water to make brine. Without

brine, the resin bed does not regenerate and you will have hard water.

If the storage tank is full of salt, it is hard to tell if you have a salt bridge. Salt is loose on top, but the bridge is under it. The following is the best way to check for a salt bridge.

Salt should be loose all the way to the bottom of the tank. Hold a broom handle, or like tool, up to the softener as shown in Fig. 41. Make a pencil mark on the handle, 1" or 2" below the top height of the rim. Then, carefully push it straight down into the salt. If a hard object is felt before the pencil mark gets to the top of the tank, it'smost likely a salt bridge. Carefully push into the bridge in a few places to break it. Do not try to break the salt bridge

by pounding on the outside of the salt tank. You may damage the tank.

If the wrong kind of salt made the bridge, take it out. Then fill the tank with nugget or pellet salt only.

NOZZLE & VENTURI

A clean nozzle and venturi (see Fig. 42) is a must for the softener to work right. This small unit moves brine from the salt storage tank to the resin tank during regeneration. If it becomes plugged with sand, silt, dirt,

etc., the softener will not work and you will get hard water.

To clean the nozzle and venturi, complete the following steps:

1.Remove the softener top cover. Be sure the softener is in service cycle (no water pressure at nozzle and venturi).

2.Turn off the cap from the nozzle and venturi housing.

3.Lift out the screen support and screen. Do not lose the large o-ring seal.

4.Remove the nozzle and venturi. Wash and rinse the parts in warm water until clean. If needed, use a small brush to remove iron or dirt. Also check and clean the gasket, flow plugs and screens.

5.Carefully replace all parts in the correct order.

6.Lubricate the o-ring seal with silicone grease or Vaseline and place in position.

7.Install and tighten the cap, by hand only. Do not overtighten, which may break the cap or housing.

IRON FROM RESIN BED

Your water softener takes hardness minerals (calcium

and magnesium) out of the water. It can also control some "clear water" iron. See maximum allowed in the

specifications section in this manual. With clear water iron, water from a faucet is clear when first put into a

glass. After 15 to 30 minutes, the water begins to cloud or turn rust colored. A water softener WILL NOT remove

any iron which makes the water cloudy or rusty as it comes from the faucet (called red water iron). To take red water iron out of water, or over the maximum of clear water iron, an iron filter or other equipment is needed. Your local Sears store has trained people to help you with iron water problems.

If your water supply has clear water iron, even though less than the maximum allowed, regular resin bed

cleaning is needed, Your local Sears store has resin bed cleaner for this, See Parts List in back of manual

for part numbers, Clean the bed at least every six (6) months, If iron shows up in the soft water before six (6) months, clean more often, Printed instructions are on the resin bed cleaner bottle,

PROTECT THE WATER SOFTENER FROM

FREEZING

If the softener is installed where it could freeze (sum- mer cabin, lake home, etc.), you must drain all water

from it to stop possible freeze damage. To drain the sof- tener:

1.Close the shut-off valve on the house main water pipe, near the water meter or pressure tank.

2.Open a faucet in the soft water pipes to vent pres- sure in the softener.

,Move the stem in a single bypass valve to bypass. Close the inlet and outlet valve in a 3 valve bypass system, and open the bypass valve. If you want water in the house pipes again, reopen the shut-off valve on the main water pipe.

,Unplug the transformer at the wall outlet. Remove the salt hole cover and the main cover. Take off both drain hoses.

,Carefully remove the large holding clips at the soften- er inlet and outlet. Separate the softener from the

plastic installation adaptors, or from the bypass valve.

,Remove the brinewell cover and disconnect the brine valve tubing at the nozzle and venturi assembly. Lift the brine valve out of the brinewell. Tip the brine valve upside down to drain water.

,Lay a piece of 2 inch thick board near the floor drain. Move the softener close to the drain. SLOWLY and CAREFULLY, tip it over until the rim rests on the wood block with the inlet and outlet over the drain.

Do not allow the softener's weight to rest on the inlet and outlet fittings or they will break.

,Tip the bottom of the softener up a few inches and hold until all water has drained. Leave the softener laying like this until you are ready to use it. Plug the inlet and outlet with rags to keep dirt, bugs, etc. out.

5.The valve drain hose must be free of kinks and sharp bends, and not elevated over 8 ft. above the floor.

. Is there salt in the storage tank?

7.Is the brine tubing connected? Brine tubing con- nects to nozzle venturi and brine valve assembly.

. Is the brine valve float set right?

9.Press the SELECT button two times to display the hardness setting.

Be sure it is the correct setting for the household's water supply. (Make a hardness test of the raw water and compare with the hardness setting. Also test a soft water sample to verify if a problem exists.) Press the SELECT button twice more to return to present time in the display.

If you do not find the problem after making initial checks, do the MANUAL INITIATED ELECTRONIC DIAGNOSTICS, and the MANUAL ADVANCE REGEN-

ERATION CHECK.

While an error code appears in the display, all faceplate buttons are inoperable except the SELECT button. SELECT remains operational so the service person can make the MANUAL INITIATED ELECTRONIC DIAGNOSTICS (below) to further isolate the problem, and check the water meter.

PROCEDURE FOR REMOVING ERROR CODE

FROM FACEPLATE:

1.??? Unplug transformer from outlet.

???Plug in transformer.

???Wait for 8 minutes.

2.??? Unplug transformer from outlet.

???Correct problem.

???Plug in transformer.

???Wait for 8 minutes.

The error code will return if the problem was not corrected.

MANUAL INITIATED ELECTRONICS DIAGNOSTICS:

To enter diagnostics, press the SELECT button until 000 - - shows in the display. See Fig. 48.

TURBINE OPERATION: If no water is flowing through the softener, the turbine indicator displays three zeros. When water is flowing, the flow bar scrolls across the display, and a 000 to 199 count repeats for each gallon of water passing through the turbine. To check for positive operation of the turbine if zeros are shown, open a nearby soft water faucet and observe the turbine count and flow bar. If you don'tget a reading in the display, with faucet open, pull the sensor from the valve outlet port. Pass a small magnet back and forth in front of the sensor. You should get a reading in the display. If you get a reading, unhook the in and out plumb- ing and check the turbine for binding.

POSITION SWITCH STATUS: With the valve in service, or any of the recharge cycles, the switch indicator will show open, while the valve is rotating from one position to anoth- er, the indicator will show the switch closed. A defect is probable if indications vary from this pattern.

TROUBLESHOOTING

VALVE POSITION INDICATORS:

Depending on the valve position, the following indica- tors show in the display:

When the valve is rotating from one cycle to another, both indicators flash. For example, if the valve is in transition between fill and brining, both Fill and Brine flash. Upon reaching brining position, Fill goes off and Brine is on steady. The time display shows the minutes of the cycle remaining.

NOTE: If the faceplate is left in a diagnostic display (or a flashing display when setting times or hard- ness), present time automatically returns if a button is not pressed within 4 minutes. To return to the diagnostic display, repeat step 1.

OTHER INFORMATION

While in this diagnostic screen, the following information is available and may be beneficial for various reasons. This information is retained by the computer from the first time electrical power is applied to the faceplate.

???Press and hold the UP button to display the number of days this faceplate has had electrical power applied.

???Press and hold the DOWN button to display the num- ber of regenerations initiated by this faceplate since the model code number was entered.

???Press the REGENERATION button to advance the valve to each position and observe the switch and position indicators to verify component operation, or to possibly isolate a defect.

???Press and hold the SELECT button for 3 seconds until a model code shows in the display, see Fig. 51.

This code identifies the softener nominal capacity size. If the wrong model code shows, the softener will operate on incorrect data. Do the following as needed.

If the correct model code (S 25) shows: Press the SELECT button to return to the present time display.

To change the number: Press the UP or DOWN but- ton until the correct model code (S 25) shows. Then, press the SELECT button and reset the timer.

This check verifies proper operation of the valve motor, brine tank fill, brine draw, regeneration flow rates, and other controller functions??? Always make the initial checks, and the manual initiated diagnos- tics.

NOTE: The faceplate display must show a steady time (not flashing). If an error code shows, first press the SELECT button to enter the diagnostic display.

1.Press the REGENERATION button and hold in for 3 seconds??? RECHARGE NOW begins to flash in the display as the softener enters the fill cycle of regen- eration. Remove the brinewell cover and, using a flashlight, observe fill water entering the tank.

2.When FILL is on steady, remove the brinewell cover and, using a flashlight, observe fill water entering the tank.

3.If water does not enter the tank, look for an obstructed nozzle, venturi, fill flow plug, brine tub- ing, or brine valve riser pipe.

CYCLE FLOW RATES (GALLONS PER MIN.)

4.After observing fill, press the REGENERATION but- ton to move the softener into brining. A slow flow of water to the drain will begin. Verify brine draw from the brine tank by shining a flashlight into the brinewell and observing a noticeable drop in the liq- uid level.

NOTE: Be sure a salt bridge is not preventing water with salt contact.

5.If the softener does not draw brine:

???nozzle and/or venturi dirty or defective

???nozzle and venturi not seated properly on gasket

???restricted drain (check drain fitting and hose)

???defective nozzle and venturi seal

???other inner valve defect (rotor seal, rotor & disc, wave washer, etc.)

NOTE: If water system pressure is low, an elevated drain hose may cause back pressure, stopping brine draw.

FIG. 52

,Again press REGENERATION to move the softener into backwash. Look for a fast flow of water from the drain hose.

,An obstructed flow indicates a plugged top distributor, backwash flow plug or drain hose.

,Press REGENERATION to move the softener into fast rinse. Again look for a fast drain flow. Allow the soften- er to rinse for a few minutes to flush out any brine that

may remain in the resin tank from the brining cycle test.

,To return the softener to service, press REGENERA- TION once more.

ROTARYVALVESERVICE

IMPORTANT: Before working on the valve, turn off the water supply and disconnect from electrical power.

TO RELIEVE PRESSURE:

???3 VALVE BYPASS: Close the inlet valve and open a soft water faucet. Then close the outlet valve and open the bypass valve.

???SEARS SPECIAL BYPASS: Slide the bypass valve stem to bypass position. Loosen three hex head screws toward the back side of the valve to allow pressure water to bleed out. Catch water with a rag.

DISASSEMBLY

To remove a part or group of parts, refer to the valve drawing. A common screwdriver or nut driver, Phillips screwdriver and pliers are the only tools needed to com- pletely disassemble.

SERVICING THE VALVE

Inspect all o-rings, seals and gaskets for wear or defects.

Inspect the bottom surface of the rotor for scratches, chips or wear.

Note: If replacement is needed, be sure to use the current replacement part.

ASSEMBLY

Be sure all parts are in place and in the proper position. Lubricate ALL o-rings and seals with FDA approved sili- cone grease. To install the rotor seal, first place the seal into the valve groove, rounded side down (see cross-sec- tion). Apply a light coating of silicone grease to the seal's crossing ribs. Then, carefully center the wear strip on the seal, and push it downward onto the seal.

Install the nozzle and venturi seal and drain seal. Assemble wave washer bearing, the wave washer, and two o-rings, onto the rotor top shaft. Then center the rotor in the valve body, on the rotor seal.

Lower the cover onto the valve body and rotor shaft. Then install the cover holding screws. Before tightening the screws, install the valve cam and gear.

Then, turn the rotor (clockwise only) to service position. Tighten the screws using a criss-cross pattern. If a torque wrench is available, torque to 30-40 inch pounds. Do not over tighten.

Lubricate the gear on the motor, and the valve cam gear with Molykote grease, or other high quality gear lubricant.

Be sure to orient switch as shown, with lever toward the cam.

WHERE TO INSTALL THE WATER SOFTENER

Review the following points before you choose a place

1.Place as close as possible but always after, the pressure tank (well water) or water meter (city water). See Fig. 3.

2.Place as close as possible to a water drain such as a floor drain, laundry tub, sump or standpipe. See Fig. 3.

3.Connect to the house main water pipe BEFORE THE WATER HEATER. See Fig. 3. Temperature of water going through the softener must not be more than 120??F (49??C). Hot water will damage inner softener parts. To reduce the risk of hot water backup, piping between the softener and water heater should be as long of a run as possible.

4.Keep outside faucets on hard water to save soft water and salt. See Fig. 3.

5.Do not install in a place where the softener could freeze. Damage caused by freezing voids the war- ranty by Sears Brands Management Corporation.

to put your softener.

6.Put the softener in a place where water damage is least likely to occur if it develops a leak. Sears or the manufacturer will not repair or pay for water damage.

7.A grounded, 120V electrical outlet is needed within 10 feet of the softener. See Fig. 3. This is to plug in the transformer. The softener has a 10 foot power cable. Be sure the outlet and transformer are in an inside place, to protect from wet weather. Use a continuously "live" outlet, which cannot be acci- dentally switched off.

8.When installing in an outside location, you must take the steps necessary to assure the softener, installa- tion plumbing, and wiring, are protected from the

elements, direct sunlight, contamination, vandalism, etc.

Run drain tubing to laundry tub or p-trap inside home, if possible. Otherwise, run to a dry well.

PIPE,FITTINGS,OTHER MATERIALS NEEDED

You must first decide how to run "in" and "out" pipes to the softener. Look at your house main water pipe at the point you will connect the softener. Is the pipe soldered copper, glued plastic, or threaded galvanized or brass?

What is the pipe size? What kind of pipe and fittings is it easiest for you to work with, and what tools do you have?

Now look at the common plans for "in" and "out" piping on soldered copper. See Fig. 6. Use it as a guide to plan what materials you will need. Get all the materials you will need before you start.

Use Fig. 5 to make a plan drawing for your specific installation. "In" and "out" fittings included with the soften- er are 1" NPT threaded adaptors. You should maintain the same, or larger, pipe size as the water supply pipe, up to the softener inlet and outlet. Use copper, brass, galvanized or PVC plastic pipe and fittings for the "in" and "out" pipes. Be sure to check local codes.

Note: If converting from galvanized to copper pipe use approved dielectric insulating connectors.

ALWAYS install the bypass valve (that is included with the unit) or a three valve bypass. See Fig. 9 to13. Bypass valves let you turn off water to the softener if needed for repairs, but still have water in the house pipes.

Drain tubing (3/8" inside diameter), is needed for the valve and salt tank drains. See Fig. 16. If a rigid valve drain is needed to comply with plumbing codes, you can buy the parts needed (see Fig. 16) to change the soften- er to a 1/2 inch minimum copper tubing drain.

*NOTE:

For plumbing connection, buy 2 sweat adaptors and plumb directly to the inlet - outlet adaptors. Threads on the inlet - outlet adaptors are 1" NPT.

CAUTION:

DO ALL SOLDERING BEFORE CONNECTING SWEAT ADAP-

TORS TO INLET-OUTLET ADAPTORS OR BYPASS VALVE.

BEFORE INSTALLING CHECKS & TESTS

Your water supply needs to be checked for chemical analysis, water pressure and water flow rate. To accom- plish this, complete the following steps:

Check Water's Chemical Analysis: Sears sells a com- plete line of water treating equipment to correct various water problems. To be sure you have the proper type and size equipment, You must have your water tested. Your Sears store can give you a water test results for hardness, iron and acidity, and tell you what equipment you need. Simply take at least a 4 oz. sample of your water to Sears, and they will test it while you wait. If you need help to get your water tested, or if you have other questions about your water, ask at your Sears store.

NOTE: Add these readings to the Facts and Figure table on page 3.

Check Your Water Pressure: For your softener to work right, a water pressure of no lower than 20 pounds per square inch (psi) is needed in the house water pipes. The highest pressure allowed in the water pipes is 125 psi. If pressure is over 125 psi, buy and install a pres-

sure reducing valve in the water inlet pipe to the soften- er.

NOTE: If water pressure during the day is 100 psi or more, pressure during the night may go over 125 psL

Adding a pressure reducing valve may reduce the flow.

NOTE: Add these readings to the Facts and Figure table on page 3.

If you have a well water system, look at the pressure gauge to find the water pressure. Call your local water department if you have city water. They will tell you what the water pressure is where you live.

NOTE: Add these readings to the Facts and Figure table on page 3.

Check your water flow rate: A water flow of at least 3 gallons per minute is needed. A lower flow will keep your softener from working as well as it should. Complete the following steps to make an easy check of your flow rate.

1.Fully open two cold water faucets close to the point water enters the house.

2.With both faucets open, fill a gallon container at one faucet while looking at a watch or clock to see how many seconds it takes.

3.Empty the container and go to the second faucet (be sure BOTH faucets are still on). Fill the gallon container at the second faucet and see how many seconds it takes.

4.Turn off both faucets. Now add the number of seconds it took to fill the container at both faucets.

5.A total of 90 seconds, or less, means the system flow rate is good.

NOTE: Add these readings to the Facts and Figure table on page 3.

NOTE: Codes in the state of Massachusetts require installation by a licensed plumber. For installation, use plumbing code 248CMR of the Commonwealth of Massachusetts.

ASSEMBLE INLET OUTLET ADAPTORS,

OR SINGLE BYPASS VALVE

Complete the following steps to assemble the adaptors or bypass valve.

1.Close the shutoff valve on the house main water pipe, near the water meter or pressure tank, to turn off the water. See Fig. 7.

2.Shut off the gas or electric supply to the water heater. See Fig. 7.

3.Open the highest and lowest water faucets in your

house. This will let water drain from the pipes. Close faucets after water has drained.

4.Remove the main cover. Remove the salt hole cover first and then pull outward on the two tabs to release main cover. See Fig. 8.

Set both covers aside so they will not get scratched or bro- ken.

INSTALL SEARS BYPASS VALVE AND / OR THE

INLET OUTLET THREADED ADAPTORS

NOTE: If you will not install the bypass valve because you will have a three (3) valve bypass, skip steps 6 & 7, but do steps 5 and 8.

5.Visually check and remove any foreign materials from the valve inlet and outlet ports. See Fig. 9. Carefully remove the two large plastic clips (you will use them). Check to be sure the turbine and turbine support are firmly in place. See Fig. 10.

BYPASS VALVE:

6.Put a light coating of silicone grease on the o-ring seals and slide onto the bypass valve.

7.Push the bypass valve into the softener valve as far as it will go. Snap the two large holding clips into place, from the top down as shown. See Fig. 11.

CAUTION: Be sure the clips snap firmly into place so the bypass valve will not pull out. See Fig. 11.

INLET AND OUTLET THREADED ADAPTORS:

8.Put a light coating of silicone grease on the o-ring seals and slide into the threaded adaptors. Push the adaptors into the valve inlet and outlet ports, or bypass valve ports, as far as they will go. Both adaptors are the same and fit either port. Snap the two large holding clips into place, as shown. See Fig. 11.

CAUTION: Be sure the clips snap firmly into place so the tubes will not pull out. See Fig. 11.

POSITION SOFTENER INTO PLACE

Complete the following steps to position the softener.

1.Grip under the ridge on the salt tank sidewall.

2.Carefully rock back and forth into position.

3.Move the softener into position.

4.Place on a level and smooth surface. If needed, put a piece of 3/4" plywood, at least 17" x 20", under the tank. Then put spacers under the plywood to level the softener. See Fig. 14.

NOTE: Do not put shims or spacers directly under the tank, without the plywood. The weight of the sof- tener, when full of salt and water, may cause the tank to puncture or break at the shim or spacer.

MOVE SOFTENER INTO PLACE

Grip under ridge to move softener.

CONNECT THE SOFTENER

Refer to your plan drawing. See Fig. 5.

Measure, cut (thread if needed) and put all pipe and fit- tings together up to the main water pipe, or to the bypass valve(s) you installed in the previous step.

CAUTION: Never solder fittings while connected to nonmetallic parts. Wait until soldered pipe has cooled before connection. See Fig. 15.

CAUTION: Be careful when putting pipe fittings together. Do not cross thread, and do not overtight-

en.

1.Cut pipe to correct length.

2.Solder (WHEN COOL, do Step 3).

3.Put threaded adaptor

CONNECT THE VALVE DRAIN HOSE

Take a length of 3/8" inside diameter drain tubing and attach one end to the drain fitting. See Fig. 16. Use a tube clamp to hold it in place. Put the other end of the tubing over a floor drain, into a laundry tub, standpipe, or other suitable drain. Check your local codes.

Leave an air gap of about 1-1/2" between the end of the hose and the drain. This gap is needed so you don'tget a backflow of sewer water into the softener. Do not put the end of the hose into the drain or con- nect without the air gap.

Place and support the hose so it does not kink or have sharp bends. Secure the hose end so water pressure does not cause the hose to "whip". Tie or wire it in place. Do not pinch the hose shut. The softener will not work if this drain hose is pinched, plugged, closed or restricted in any way. Direct drain flow

down into drain from drain line as flow could possibly over shoot the drain cover.

Keep the hose lower than the drain fitting. In some homes, to get to a drain you must raise the hose and run it overhead. If you need an overhead drain, do not raise the hose more than 8'above the floor. A copper drain tube is best to use.

COPPER DRAIN TUBE: Local plumbing codes may require the use a copper valve drain tube. A copper

Grommet Tube

_, Adapto_

tube is also best to use for an overhead drain. Use a copper drain tube if the softener is installed outside, or in the sunlight. Heat from the sun can soften, flatten and close up some kinds of tubes.

To adapt a copper drain tube to the softener, buy a compression fitting (1/4" female pipe threads x 1/2" O.D. tube) and tubing from your local hardware store.

CONNECT SALT TANK OVERFLOW TUBING

1.Locate the rubber grommet, tube adaptor and tube clamp (see Fig. 16) that are in the parts bag.

2.Push the grommet into the hole in the salt tank wall so half is inside and half is outside.

3.Push the bigger end of the tube adaptor into the grommet.

4.Push one end of a length of 3/8" I.D. tubing onto the tube adaptor, using the tube clamp to hold it in place.

5.Put the other end of the tubing over the floor drain.

IMPORTANT: Overflow water must run downward through the tubing. Do not raise the tubing higher than the grommet and tube adaptor. See Fig. 16. IMPORTANT: Do not connect to the valve drain hose you installed in step 1. Both drains must have a separate hose or tube.

NOTE: Overflow drain tubing is available from

Sears. See parts list in back of manual.

LEAK TEST

To check for leaks, complete the following steps:

CAUTION: To avoid water or air pressure dam- age to softener inner parts, and to flush pipe chips or other residue from the water pipes, be

sure to do the following steps exactly asShu_ instructed.

HOUSE MAIN WATER

SHUTOFF VALVES

1.Fully open two cold, soft water faucets near the softener.

2.Look at the pictures in Fig. 18 and 19 to deter- mine your kind of bypass valve(s). Place bypass valve(s) in "bypass" position. On a single valve, slide the stem inward to bypass. On a three (3) valve system, close the inlet and outlet valves and open the bypass valve.

3.Fully open the house main water pipe shutoff

valve. Observe steady water flow from both open faucets.

4.Place bypass valve(s) in SERVICE EXACTLY as follows: Keep soft water faucets open.

a. Single Bypass Valve: Slowly, slide pull the valve stem outward toward service, pausing sev- eral times to allow the softener to pressurize slow- ly.

b. Three Valve Bypass: Fully close the bypass valve and open the outlet valve. Slowly, open the inlet valve, pausing several times to allow the sof- tener to pressurize slowly.

5.After about three minutes, open a hot water faucet for about one minute, or until all air is expelled, then close.

6.Close both cold water faucets.

7.Check your plumbing work for leaks and fix right

away if any are found. Be sure to observe previ- ous caution notes.

NOTE: If this procedure is performed on a new softener, water coming from the taps may initial- ly be discolored. This normally occurs the first time water runs through the resin bed. The dis- colored water is not harmful, and the discol- oration will not last more than a few minutes.

INSTALLGROUNDINGCLAMPBETWEEN

THESOFTENERINAND OUT PIPES

The house cold water pipe (iron or copper) is often used to ground all electrical outlets in the home. Outlets are grounded to protect you from shock when you touch any electric appliance plugged into the out- let. If you installed the single bypass valve, the cold water pipe ground is broken. See Fig. 20 and 21.

IMPORTANT: Be sure the cold water pipe has direct metal to metal contact all the way to the ground. Plastic, rubber or other electrically insulat- ing parts such as hoses, fittings, washers or gas- kets can break the direct metal to metal contact. Also check the water meter (city water) or the well pump. Install #4 copper jumper wires, clamped tightly on both ends, across insulated parts. See Fig. 21.

To restore the ground, take the ground clamp kit that is in the parts bag. Install across the inlet and outlet cop- per tubes. See Fig. 20. Be sure good contact is made between the pipe and the clamps.

ELECTRICAL POWER OUTLET FOR

YOUR SOFTENER

The softener works on 24 volt, 60 Hz electric power. The included transformer changes standard 120 volt AC house power to 24 volts. You must plug the trans- former into a grounded, 120 volt outlet only. Be sure the outlet is always "live" so someone cannot turn it off by mistake. See Fig. 22.

NOTE: The included transformer is made for inside

use only. Be sure the electrical outlet you plug the transformer into is inside, to protect from weather.

NOTE: Each press of the UP or DOWN button changes the display by 1 between 1 and 25. Between 25 and the highest number, the display changes 5 at a time (25, 30, 35, etc.) Holding the

UP or DOWN button in changes the display twice each second.

SET REGENERATION TIME

To complete setting the regeneration time, complete the following steps:

1.Press the SELECT button to display the words SET RECHARGE TIME and a flashing 2:00 AM.

2.At the 2:00 AM recharge time setting, the softener begins regeneration (see pages 25 - 27) at 2:00 AM. This is a good time in most households because water is not being used. If a different recharge time setting would be better for your household, complete the following step.

3.Press the UP or DOWN buttons to set the desired recharge starting hour. Be sure to observe the AM- PM as you did when setting the present time of day.

Note: Each press of the UP or DOWN buttons changes the display one hour. Holding the but- tons in changes the display twice each second.

SET SALT LEVEL

To set the salt level, complete the following steps:

1.Press the SELECT button to display SET SALT LEVEL and a flashing 0 (zero). See page 21, for instructions on adding salt to the salt storage tank. The face plate timer has a salt monitor with an indi-

cator light to remind you to add salt to the storage tank.

NOTE:You must set salt level each time salt is added to the water softener.

2.To set this monitor system, lift the salt hole cover and level the salt in the storage tank. The salt level decal, on the brinewell inside the tank, has numbers from 0 to 8. Observe the highest number the leveled salt is at, or closest to. Press the UP or DOWN but- tons until the number corresponds with the salt level number. At level 2 or below, the indicator LED will flash. If you wish to turn this feature off, press the DOWN button past 0, and the word "OFF" flashes in the display.

3.Press the SELECT button once again, to complete initial programming, and the current time of day will show in the display.

SANITIZE THE WATER SOFTENER

Care is taken at the factory to keep your water softener clean and sanitary. Materials used to make the softener will not infect or contaminate your water supply, or cause bacteria to form or grow. However, during shipping, storage, installing and operating, bacteria could get into the softener.

SANITIZE YOUR WATER SOFTENER AS FOLLOWS:

1.Be certain the bypass valve is pulled out to

"service" position.

2.Lift the salt hole cover and using a pail add up to 3 gallons of water to the salt storage tank.

3.Remove the brine well cover (Fig. 28) and pour about 3/4 ounce, or 1 to 2 tablespoons, of common 5.25% 1, unscent- ed, household bleach (Clorox, Linco, BoPeep, White Sail, Eagle, etc.) in the softener brinewell. Replace the brinewell cover.

4.Press the REGENERATION button and hold for 3 seconds to start a recharge. This first recharge does several things.

???It draws the bleach into and through the softener to sani- tize it.

???It fills the salt tank to the water level needed.

???It gets all the air out of the resin tank.

???It prepares the resin bed (see page 25) for service and flushes residual chlorine from the softener.

NOTE: This recharge takes about 2-1/2 to 2-3/4 hours, depending on the salt type setting.

NOTE: During a recharge the water softener bypasses raw water to the home. You will not get salty water or affect the regeneration cycle if water is used at this time.

You can sanitize the softener with or without salt in the storage tank.

1Recommended by the Water Quality Association.

On some water supplies, the water softener may need peri- odic disinfecting.

Your new Sears softener is now softening the water for your household needs. However, your WATER HEATER is filled with hard water. To have fully soft water right away, you can drain the water heater so it refills with soft water. If you don't drain the water heater, it will take a few days before you have fully soft water.

To drain the water heater, open a hot water faucet and let it run until the water runs cold. Then close the faucet.

NOTE: If this procedure is performed on a new softener, water coming from the taps may initially be discolored.

This normally occurs the first time water runs through the resin bed. The discolored water is not harmful, and the discoloration will not last more than a few minutes.

If you choose Potassium Chloride (KCl) as a regenerant,

following these suggestions will help give you years of maintenance free service.

1.Place only one bag of KCl in your softener at a time (the salt storage tank should contain no more than 60 pounds of KCl at any one time).

2.A softener using KCl should not be placed in areas with temperature fluctuations and high humidity (KCl will harden in these environments and may make the softener inoperable).

3.Check the brine tank and brine well (black tube in salt

storage tank) monthly. If hardening is present, pour small amounts of warm water on hardened areas until

they loosen.

4.If your softener does not have a KCl salt setting you must increase your hardness setting by 25% to ensure continuous soft water as in example below.

FIG.29

Persons who are on sodium restricted diets should con- sider the added sodium as part of their overall sodium intake. For example, if your water supply is 15 grains hard, and you drank 3 quarts of softened water you would consume 335 milligrams of sodium. That is equivalent to eating 2-1/2 slices of white bread.

WATER SOFTENING SALT WITH IRON

REMOVING ADDITIVES

Some salts have an additive to help the softener handle iron in the water supply. These salts may be used if your water supply has a high iron content. It is recom- mended to use Sears Resin Bed Cleaner (refer to the Parts List in back of manual for part number) for period- ic treatments to keep your resin bed clean. This is avail- able at your local Sears store.

Persons who are concerned about their drinking water

should consider a Kenmore Drinking Water System that will remove or reduce in excess of 90% of the sodium

and other drinking water contaminants.

Press and release (do not hold) the REGENERATION button. RECHARGE TONIGHT flashes in the display, and the softener begins regeneration at the next preset recharge time. Press and release the RECHARGE but- ton once more if you decide to cancel the regeneration, and RECHARGE TONIGHT will not flash in the display.

SALT MONITOR SYSTEM

The face plate timer has a low salt monitor with an indi- cator light to remind you to add salt to the storage tank.

To set this monitor system:

1.Lift the salt hole cover and level the salt in the storage tank.

2.The salt level decal, on the brinewell inside the tank, has numbers from 0 to 8. Observe the number the lev- eled salt is at or closest to.

3.Press SELECT once to get to the Set Salt Level screen. Now press the UP or DOWN buttons until the number corresponds with the salt level number. At level 2 or below, the indicator LED will flash. If you wish to turn this feature off, press the DOWN button past 0, and the word "OFF" flashes in the display.

NOTE: You must set salt level each time salt is added to the water softener.

CaliforniaEfficiency Requirement

Your Kenmore Water Softener has a "High Efficiency" feature with an "ON" or "OFF" setting. This softener setting is shipped in the "OFF" position, which utilizes the maximum rated capacity while most often achiev- ing maximum salt efficiencies. When installing this unit in the State of California, you MUST turn this setting to the "ON" position which may initiate more frequent recharges, however it will operate at 4000 grains per pound of salt or higher.

EFFICIENCY MODE

When this feature is ON, the water softener will operate at salt efficiencies of 4000 grains of hardness per pound of salt or higher. (May recharge more often using smaller salt dosage and less water). Installations in the state of

California require this setting to be turned ON. This softener is shipped in the OFF setting.

To turn this setting ON:

1.Press and hold the SELECT button until the display shows 000--.

2.Then press (do not hold) the SELECT button again. Use the UP arrow to turn ON.

3.Press SELECT to enter and return to normal running

screen. The efficiency icon will only be displayed when this feature is ON.

PROGRAM MEMORY

If electrical power to the softener goes off, the time dis- play is blank but the face plate timer keeps the correct time for about 6 hours. When electrical power comes on again, you have to reset the present time only if the dis- play is flashing. The HARDNESS, RECHARGE TIME and SALT LEVEL never require resetting unless a change is desired. Even if the timer is incorrect after a long power outage, the softener works as it should to keep your water soft, however, regenerations may occur at the wrong time of day until you reset the timer to the correct time of day.

ERROR CODE

An error code could appear in the face plate display if a problem occurs in the softener electronics. Turn to the

Troubleshooting section to resolve the problem and/or call the Kenmore Water Line number listed below.

SOFT WATER SERVICE AND REGENERATION

SERVICE

When the softener is giving you soft water, it is called "Service". See Fig. 36. During service, hard water comes from the house main water pipe into the soften- er. Inside the softener resin tank is a bed made up of thousands of tiny, plastic resin beads. As hard water passes through the bed, each bead attracts and holds the hardness minerals. This is called ion exchanging. Water without the hardness minerals (soft water) flows out of the softener and into the house soft water pipes. After a period of time, the resin beads hold all of the hardness minerals they can, and cleaning with salt brine is needed. This cleaning is called regeneration or recharge. Regeneration is started at 2:00 a.m. by the electronic timer. It takes place in 5 stages or cycles.

These are: 1. Fill

2.Brining

3.Brine Rinse

4.Backwash

5.Fast Rinse

REGENERATION

The five steps listed above are described in detail over the next several pages.

FILL: Salt, dissolved in water, is called brine. Brine is needed to clean the hardness minerals from the resin beads. To make the brine, water flows into the salt stor- age area during the fill stage. See Fig. 37. Fill cycle length depends on how much soft water making capaci- ty you have used since the last regeneration. As you use more water, fill time increases so more brine is

made. The greater amount of brine cleans more hard- ness minerals from the resin bed.

SOFT WATER SERVICE AND REGENERATION

BRINING: During brining, the brine is moved from the salt storage area, into the resin tank. See Fig. 38. Inside the resin tank, brine cleans hardness minerals from the resin beads and they are discharged out the drain. How much brine is needed to clean the resin depends on:

???The amount of water used between regenerations.

???The amount of resin in the softener,

???How fast the brine goes through the bed.

The nozzle and venturi makes suction to take brine from the salt tank and put it into the resin tank. They keep the brine flow down to a very slow rate to get the best resin cleaning with the least salt.

BRINE RINSE: After all of the brine is moved into the resin tank, the brine valve closes. Water keeps flowing the same way it did during brining except the brine flow has stopped. Hardness minerals and brine flush from the resin tank to the drain. Brining and brine rinse together vary in the length of time they take, relative to the fill cycle length. See Fig. 38.

BACKWASH: During backwash, water flows UP through the resin tank at a fast rate to flush iron miner- als, dirt and sediments from the bed and to the drain. The bed lifts and expands for good cleaning. See Fig. 39.

FAST RINSE: Backwash is followed by a fast flow of water down through the resin tank. The fast flow packs the resin bed and gets it ready for return to service. See Fig. 40.

After fast rinse, the softener returns to service. Hard water goes into the resin tank where the resin bed again takes out the hardness minerals. Soft water goes to the house soft water pipes.

SOFT WATER SERVICE AND REGENERATION

AUTOMATIC BYPASS

During the brining, brine rinse and backwash cycles of regeneration, HARD water goes through the softener valve and to the house pipes. If a faucet is opened, hard water is there for your needs. However, you should not use hot water, if possible, because the water heater will refill with hard water. The softener, as factory pro- grammed, regenerates from 2:00 AM to about 4:20 AM, a time when not much water is used.

If you start your day prior to 4 AM, you may need to change the recharge starting time. Set the recharge time to 12:00 AM or 1:00 AM. Then regeneration will start and end that much earlier and your water heater will not refill with hard water if a hot faucet is opened.

ELECTRONICS

Two main parts of the softener's electronics are: a WATER METER, and a COMPUTER.

???WATER METER The water meter is in the softener valve outlet. As water flows through the meter, it sends electric pulses to the computer. The computer changes the puls- es to a measure in gallons of water.

???COMPUTER The computer is part of the faceplate timer circuit board. It is programmed to know the softener's capacity (how many grains of hardness minerals it will take out of the water before a regeneration is needed). When starting the softener, you set it for the grains per gallon (gpg) hardness of the water.

To find a regeneration pattern best for your needs, the computer uses:

(1)water usage from the meter

(2)hardness setting

(3)softener capacity

(4)time since the last regeneration.

l-' l

FIG. 40

The computer always adjusts this pattern to your water using habits. It works toward providing you with soft water for the longest time and at the most efficient salt usage.

Softening capacity is used as hard water goes through the softener and hardness minerals are removed. When the computer determines that only enough capacity remains to provide soft water up to the next regenera- tion starting time (2:00 AM, or as otherwise set) it will schedule a regeneration. When the regeneration

begins, RECHARGE NOW flashes in the display during the regeneration.

SALT BRIDGE

Sometimes, a hard crust or salt bridge forms in the salt storage tank. It is usually caused by high humidity or the wrong kind of salt. When the salt bridges, an empty space forms between the water and salt. Then salt will not dissolve (melt) in the water to make brine. Without

brine, the resin bed does not regenerate and you will have hard water.

If the storage tank is full of salt, it is hard to tell if you have a salt bridge. Salt is loose on top, but the bridge is under it. The following is the best way to check for a salt bridge.

Salt should be loose all the way to the bottom of the tank. Hold a broom handle, or like tool, up to the softener as shown in Fig. 41. Make a pencil mark on the handle, 1" or 2" below the top height of the rim. Then, carefully push it straight down into the salt. If a hard object is felt before the pencil mark gets to the top of the tank, it'smost likely a salt bridge. Carefully push into the bridge in a few places to break it. Do not try to break the salt bridge

by pounding on the outside of the salt tank. You may damage the tank.

If the wrong kind of salt made the bridge, take it out. Then fill the tank with nugget or pellet salt only.

NOZZLE & VENTURI

A clean nozzle and venturi (see Fig. 42) is a must for the softener to work right. This small unit moves brine from the salt storage tank to the resin tank during regeneration. If it becomes plugged with sand, silt, dirt,

etc., the softener will not work and you will get hard water.

To clean the nozzle and venturi, complete the following steps:

1.Remove the softener top cover. Be sure the softener is in service cycle (no water pressure at nozzle and venturi).

2.Turn off the cap from the nozzle and venturi housing.

3.Lift out the screen support and screen. Do not lose the large o-ring seal.

4.Remove the nozzle and venturi. Wash and rinse the parts in warm water until clean. If needed, use a small brush to remove iron or dirt. Also check and clean the gasket, flow plugs and screens.

5.Carefully replace all parts in the correct order.

6.Lubricate the o-ring seal with silicone grease or Vaseline and place in position.

7.Install and tighten the cap, by hand only. Do not overtighten, which may break the cap or housing.

IRON FROM RESIN BED

Your water softener takes hardness minerals (calcium

and magnesium) out of the water. It can also control some "clear water" iron. See maximum allowed in the

specifications section in this manual. With clear water iron, water from a faucet is clear when first put into a

glass. After 15 to 30 minutes, the water begins to cloud or turn rust colored. A water softener WILL NOT remove

any iron which makes the water cloudy or rusty as it comes from the faucet (called red water iron). To take red water iron out of water, or over the maximum of clear water iron, an iron filter or other equipment is needed. Your local Sears store has trained people to help you with iron water problems.

If your water supply has clear water iron, even though less than the maximum allowed, regular resin bed

cleaning is needed, Your local Sears store has resin bed cleaner for this, See Parts List in back of manual

for part numbers, Clean the bed at least every six (6) months, If iron shows up in the soft water before six (6) months, clean more often, Printed instructions are on the resin bed cleaner bottle,

PROTECT THE WATER SOFTENER FROM

FREEZING

If the softener is installed where it could freeze (sum- mer cabin, lake home, etc.), you must drain all water

from it to stop possible freeze damage. To drain the sof- tener:

1.Close the shut-off valve on the house main water pipe, near the water meter or pressure tank.

2.Open a faucet in the soft water pipes to vent pres- sure in the softener.

,Move the stem in a single bypass valve to bypass. Close the inlet and outlet valve in a 3 valve bypass system, and open the bypass valve. If you want water in the house pipes again, reopen the shut-off valve on the main water pipe.

,Unplug the transformer at the wall outlet. Remove the salt hole cover and the main cover. Take off both drain hoses.

,Carefully remove the large holding clips at the soften- er inlet and outlet. Separate the softener from the

plastic installation adaptors, or from the bypass valve.

,Remove the brinewell cover and disconnect the brine valve tubing at the nozzle and venturi assembly. Lift the brine valve out of the brinewell. Tip the brine valve upside down to drain water.

,Lay a piece of 2 inch thick board near the floor drain. Move the softener close to the drain. SLOWLY and CAREFULLY, tip it over until the rim rests on the wood block with the inlet and outlet over the drain.

Do not allow the softener's weight to rest on the inlet and outlet fittings or they will break.

,Tip the bottom of the softener up a few inches and hold until all water has drained. Leave the softener laying like this until you are ready to use it. Plug the inlet and outlet with rags to keep dirt, bugs, etc. out.

5.The valve drain hose must be free of kinks and sharp bends, and not elevated over 8 ft. above the floor.

. Is there salt in the storage tank?

7.Is the brine tubing connected? Brine tubing con- nects to nozzle venturi and brine valve assembly.

. Is the brine valve float set right?

9.Press the SELECT button two times to display the hardness setting.

Be sure it is the correct setting for the household's water supply. (Make a hardness test of the raw water and compare with the hardness setting. Also test a soft water sample to verify if a problem exists.) Press the SELECT button twice more to return to present time in the display.

If you do not find the problem after making initial checks, do the MANUAL INITIATED ELECTRONIC DIAGNOSTICS, and the MANUAL ADVANCE REGEN-

ERATION CHECK.

While an error code appears in the display, all faceplate buttons are inoperable except the SELECT button. SELECT remains operational so the service person can make the MANUAL INITIATED ELECTRONIC DIAGNOSTICS (below) to further isolate the problem, and check the water meter.

PROCEDURE FOR REMOVING ERROR CODE

FROM FACEPLATE:

1.??? Unplug transformer from outlet.

???Plug in transformer.

???Wait for 8 minutes.

2.??? Unplug transformer from outlet.

???Correct problem.

???Plug in transformer.

???Wait for 8 minutes.

The error code will return if the problem was not corrected.

MANUAL INITIATED ELECTRONICS DIAGNOSTICS:

To enter diagnostics, press the SELECT button until 000 - - shows in the display. See Fig. 48.

TURBINE OPERATION: If no water is flowing through the softener, the turbine indicator displays three zeros. When water is flowing, the flow bar scrolls across the display, and a 000 to 199 count repeats for each gallon of water passing through the turbine. To check for positive operation of the turbine if zeros are shown, open a nearby soft water faucet and observe the turbine count and flow bar. If you don'tget a reading in the display, with faucet open, pull the sensor from the valve outlet port. Pass a small magnet back and forth in front of the sensor. You should get a reading in the display. If you get a reading, unhook the in and out plumb- ing and check the turbine for binding.

POSITION SWITCH STATUS: With the valve in service, or any of the recharge cycles, the switch indicator will show open, while the valve is rotating from one position to anoth- er, the indicator will show the switch closed. A defect is probable if indications vary from this pattern.

TROUBLESHOOTING

VALVE POSITION INDICATORS:

Depending on the valve position, the following indica- tors show in the display:

When the valve is rotating from one cycle to another, both indicators flash. For example, if the valve is in transition between fill and brining, both Fill and Brine flash. Upon reaching brining position, Fill goes off and Brine is on steady. The time display shows the minutes of the cycle remaining.

NOTE: If the faceplate is left in a diagnostic display (or a flashing display when setting times or hard- ness), present time automatically returns if a button is not pressed within 4 minutes. To return to the diagnostic display, repeat step 1.

OTHER INFORMATION

While in this diagnostic screen, the following information is available and may be beneficial for various reasons. This information is retained by the computer from the first time electrical power is applied to the faceplate.

???Press and hold the UP button to display the number of days this faceplate has had electrical power applied.

???Press and hold the DOWN button to display the num- ber of regenerations initiated by this faceplate since the model code number was entered.

???Press the REGENERATION button to advance the valve to each position and observe the switch and position indicators to verify component operation, or to possibly isolate a defect.

???Press and hold the SELECT button for 3 seconds until a model code shows in the display, see Fig. 51.

This code identifies the softener nominal capacity size. If the wrong model code shows, the softener will operate on incorrect data. Do the following as needed.

If the correct model code (S 25) shows: Press the SELECT button to return to the present time display.

To change the number: Press the UP or DOWN but- ton until the correct model code (S 25) shows. Then, press the SELECT button and reset the timer.

This check verifies proper operation of the valve motor, brine tank fill, brine draw, regeneration flow rates, and other controller functions??? Always make the initial checks, and the manual initiated diagnos- tics.

NOTE: The faceplate display must show a steady time (not flashing). If an error code shows, first press the SELECT button to enter the diagnostic display.

1.Press the REGENERATION button and hold in for 3 seconds??? RECHARGE NOW begins to flash in the display as the softener enters the fill cycle of regen- eration. Remove the brinewell cover and, using a flashlight, observe fill water entering the tank.

2.When FILL is on steady, remove the brinewell cover and, using a flashlight, observe fill water entering the tank.

3.If water does not enter the tank, look for an obstructed nozzle, venturi, fill flow plug, brine tub- ing, or brine valve riser pipe.

CYCLE FLOW RATES (GALLONS PER MIN.)

4.After observing fill, press the REGENERATION but- ton to move the softener into brining. A slow flow of water to the drain will begin. Verify brine draw from the brine tank by shining a flashlight into the brinewell and observing a noticeable drop in the liq- uid level.

NOTE: Be sure a salt bridge is not preventing water with salt contact.

5.If the softener does not draw brine:

???nozzle and/or venturi dirty or defective

???nozzle and venturi not seated properly on gasket

???restricted drain (check drain fitting and hose)

???defective nozzle and venturi seal

???other inner valve defect (rotor seal, rotor & disc, wave washer, etc.)

NOTE: If water system pressure is low, an elevated drain hose may cause back pressure, stopping brine draw.

FIG. 52

,Again press REGENERATION to move the softener into backwash. Look for a fast flow of water from the drain hose.

,An obstructed flow indicates a plugged top distributor, backwash flow plug or drain hose.

,Press REGENERATION to move the softener into fast rinse. Again look for a fast drain flow. Allow the soften- er to rinse for a few minutes to flush out any brine that

may remain in the resin tank from the brining cycle test.

,To return the softener to service, press REGENERA- TION once more.

ROTARYVALVESERVICE

IMPORTANT: Before working on the valve, turn off the water supply and disconnect from electrical power.

TO RELIEVE PRESSURE:

???3 VALVE BYPASS: Close the inlet valve and open a soft water faucet. Then close the outlet valve and open the bypass valve.

???SEARS SPECIAL BYPASS: Slide the bypass valve stem to bypass position. Loosen three hex head screws toward the back side of the valve to allow pressure water to bleed out. Catch water with a rag.

DISASSEMBLY

To remove a part or group of parts, refer to the valve drawing. A common screwdriver or nut driver, Phillips screwdriver and pliers are the only tools needed to com- pletely disassemble.

SERVICING THE VALVE

Inspect all o-rings, seals and gaskets for wear or defects.

Inspect the bottom surface of the rotor for scratches, chips or wear.

Note: If replacement is needed, be sure to use the current replacement part.

ASSEMBLY

Be sure all parts are in place and in the proper position. Lubricate ALL o-rings and seals with FDA approved sili- cone grease. To install the rotor seal, first place the seal into the valve groove, rounded side down (see cross-sec- tion). Apply a light coating of silicone grease to the seal's crossing ribs. Then, carefully center the wear strip on the seal, and push it downward onto the seal.

Install the nozzle and venturi seal and drain seal. Assemble wave washer bearing, the wave washer, and two o-rings, onto the rotor top shaft. Then center the rotor in the valve body, on the rotor seal.

Lower the cover onto the valve body and rotor shaft. Then install the cover holding screws. Before tightening the screws, install the valve cam and gear.

Then, turn the rotor (clockwise only) to service position. Tighten the screws using a criss-cross pattern. If a torque wrench is available, torque to 30-40 inch pounds. Do not over tighten.

Lubricate the gear on the motor, and the valve cam gear with Molykote grease, or other high quality gear lubricant.

Be sure to orient switch as shown, with lever toward the cam.
