SECTION 1

WATER SOFTENER START-UP

1D. SANITIZING 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, and will not cause bacteria to form or grow. However, during shipping, storage, installing and operating, bacteria could get into the softener. For this reason, sanitizing as follows is suggested??? when installing.

1. The first time you sanitize your softener, be sure to do ????????? steps in the installation manual, and on pages 5, 6 and 7 of this manual first.

2. Lift the salt hole cover and use a pail or hose to fill the salt storage tank with at least 3 gallons of water.

3. Remove the brinewell cover (FIG. 3) and pour about 3/4 ounce of common 5.25% household bleach (Clorox, Linco, BoPeep, White Sail, Eagle, etc.) in the softener brinewell.

4. Press the ON/OFF???HOLD button and hold for 3 seconds to start a recharge. This first recharge does several things.

:It draws the bleach into and through the soft9 ener to sanitize it.

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

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

:It makes the resin bed (see page 11) ready for service.

NOTES:

This recharge takes about 2 hours.

If the CLEAN feature is set to ON, a cleaning backwash will occur first (CLEAN and Bkwsh or Rinse flashes in the display), before the sanitizing recharge. Recharge takes about 2 hours and 15 minutes when the clean feature is on.

You can sanitize the softener w????????? ?????? w???????????? ???u??? salt in the storage tank.

???Recommended by the Water Quality Association. On some water supplies, the water softener may need peri9 odic disinfecting.

WATER SOFTENER START-UP

1E. FILL THE STORAGE TANK WITH SALT

Brine (salt dissolved in water) is needed for each and every regeneration. The water for making brine is metered into the salt storage tank by the softener. However, you must keep the tank filled with salt.

Fill the tank with NUGGET or PELLET water softener salt. DO NOT use rock salts, as they have dirt and sediments that will stop the softener from working.

Before filling, be sure the brinewell cover is in place on the top of the brinewell. Salt storage capacity is shown on page 19. Be sure to set the salt monitor system (see page 10).

NOTES:

The salt monitor system (page 10) is calibrated to the density of nugget or pellet water softener salt. The monitor will not work as accurately with other types of salt including rock and solar.

In humid areas, it is best to fill the storage tank half9full, and to refill it more often. Salt bridging (see page 15) occurs more often when conditions are humid.

WATER SOFTENING SALT WITH IRON REMOV- ING ADDITIVES ?? Some salts have an additive to help the softener handle iron in the water supply. Although this additive may help to keep the softener resin clean, it may also release corrosive fumes that will weaken and shorten the life of some softener parts.

FIG. 3 ADD SALT

Sod??????m ??????forma??????o???: Water softeners using sodium chloride for regeneration add sodium to the water. Persons who are on sodium restricted diets should consider the added sodium as part of their overall sodium intake.

For example, if your water supply is 15 grains hard, you would have to drink 3 quarts of softened water to consume 335 milligrams of sodium. That is equivalent to eating 291/2 slices of white bread.

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.

You have now finished the water softener start up. After the sanitizing recharge, on page 8, the softener will be giving you soft water.

EXTRA RECHARGE

Sometimes, a manually started regeneration (re: charge) may be desired, or needed. Two examples are:

--You have used more water than usual (guests visiting) and you may run out of soft water before the next timer started regeneration.

--You did not refill the softener with salt before it was gone.

You can start a regeneration right away, or you can set the timer to regenerate at the next 2:00 AM (or other preset recharge time). Do the following.

RECHARGE TONIGHT.

SALT MONITOR SYSTEM

The face plate timer has a low salt monitor with an indicator light to remind you to refill the storage tank with salt. 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 (see drawing on page 9 and below). Observe the number the leveled salt is at or closest to.

3.Now, press the SALT LEVEL ADJUST button until black bars display up to the salt level number. For example, the pictures below show the salt level at 6.

4.Finally, set the level you want the low salt

indicator light to come on. Press the SIGNAL LIGHT ADJUST button until a (???) shows opposite this number. In the example below, the light will come one when the stored salt drops to level 2. At level 2, the storage tank is about 1/3 full. This is the lowest you should allow the stored salt level to drop to. To turn the salt monitor off, press the button until OFF shows.

NOTE:

For accurate salt monitor operation, always use nugget or pellet water softener salt. See page 9.

MINUTES, MAXIMUM DAYS BETWEEN REGEN- ERATIONS, and 12 / 24 HOUR TIME READINGS:

1. To set 1, 2 or all 3 options, press and hold SELECT for 3 seconds. Then press again until the CLEAN TIME display shows.

If soft water is in use, the water flow bars continually scroll across the display. The bars scroll slowly when water flow is slow, and move faster as water flow increases. The flow bars do not show when all faucets and water using appliances are off.

CLEAN feature minutes: If you are using this feature (page 7), the length of the extra backwash cycle automatically sets to 7 minutes. However, you can adjust this time from 1 to 15 minutes in length. To change this cycle time, use the UP button to increase the time, or the DOWN button to shorten the time. If no change is desired, continue below.

2. Press SELECT again to show the following RECHARGE display.

Maximum days between regenerations: The faceplate timer automatically controls regeneration frequency (see page 14). This provides the greatest operating efficiency, and normally the maximum days feature is not needed. If you want to be certain a regeneration will occur within a number of days, use this feature. For example, if your water supply contains iron and you want the softener to regenerate at least once every few days to keep the resin bed clean, set the display as typically shown above. Setting is available from 1 to 15 days by using the UP and DOWN buttons.

3. Press SELECT to show the 12 HOUR display.

PROGRAM MEMORY

If electrical power to the softener goes off, the time display 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 display is flashing. The HARDNESS and RECHARGE TIME 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.

12 or 24 hour clock: All time displays are shown in standard clock time (1 to 12 PM; and 1 to 12 AM) at the 12 hr default setting. If military time displays are desired, set to 24 hr by pressing the UP button.

SECTION 2

HOW YOUR WATER SOFTENER WORKS

2B. SOFT WATER SERVICE AND REGENERATION

When the softener is giving you soft water, it is called ???Service". During service, hard water flows through the house main water pipe into the softener. Inside the softener resin tank is a bed made up of thousands of tiny, plastic resin beads (FIG. 4). As hard water passes through the bed, each bead attracts and holds the hardness minerals. This is called ion5exchanging. It is much like a magnet attracting and holding metals. 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 become coated with hardness minerals and they have to be cleaned. This cleaning is called regeneration or recharge. Regeneration is started at 2:00 a.m. by the electronic timer (see page 14). It takes place in 5 stages or cycles. These are:

NOTE:

If the CLEAN feature (page 7) is set to ON, additional backwash and fast rinse cycles occur before the fill cycle.

FIG. 4 WATER FLOW THROUGH THE

SOFTENER IN SERVICE

??? 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 storage area during the fill stage as shown in FIG. 5. Fill cycle length depends on how much soft water making capacity 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 hardness minerals from the resin bed.

SECTION 2

HOW YOUR WATER SOFTENER WORKS

2B. SOFT WATER SERVICE AND REGENERATION

???BRINING: During brining, the brine is moved from the salt storage area, into the resin tank. 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 resin in the softener, --how fast the brine goes through the bed.

The nozzle and venturi (FIG. 6) make 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 goes 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.

???BACKWASH: During backwash, water flows UP through the resin tank (FIG. 7) at a fast rate to flush iron minerals, dirt and sediments from the bed and to the drain. The bed lifts and expands for good cleaning.

???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 (FIG. 8).

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.

SECTION 2

HOW YOUR WATER SOFTENER WORKS

2B. SOFT WATER SERVICE AND REGENERATION

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 regenerates from 2:00 AM to about 4:00 AM, (you can set anytime), a time when not much water is used.

If you get up early in the morning and you can hear the softener regenerating, change the time setting. Set the recharge time to 12:00 AM or 1:00 AM (page 7). 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.

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

???WATER METER 6 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 pulses to a measure in gallons of water.

???COMPUTER 6 The computer is part of the 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, page 7, 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, and (4) time since the last regeneration. The computer always adjusts this pattern to your water using habits. It works toward providing you with soft water for the longest time and the most efficient salt usage.

Softening capacity is used as hard water goes through the softener and hardness minerals are removed, capacity is used. When the computer determines that only enough capacity remains to provide soft water up to the next regeneration starting time (2:00 AM, or as otherwise set) it will schedule a regeneration. RECHARGE TONIGHT displays until the regeneration begins. When the regeneration begins, TONIGHT goes off and *RE??? CHARGE or RECHARGE TIME REMAINING flashes during the 2 hour regeneration.

*NOTE:

If the CLEAN feature is set to ON, a cleaning backwash (CLEAN and Bkwsh or Rinse flashes in the display, along with the minutes of the clean cycle remaining), precedes the recharge.

3A. SALT??? REFILLING STORAGE TANK/BREAKING A SALT BRIDGE

WHEN TO REFILL WITH SALT

The Salt Monitor System (see page 10) will turn on the low salt light to warn you when to refill with salt. Check for a low salt light a few weeks after you install the softener, and every week after that. Always refill at about the #2 salt monitor level. At this level, the tank is about 1/3 full. Never let the softener use

all the salt before refilling. Without salt, you will soon have hard water.

NOTE:

You will have a loss in softening capacity and may get partly hard water if less than 10 inches (salt monitor level 2) of salt is in the storage tank.

PLEASE SEE PAGE 9 FOR SALT FILLING DIRECTIONS.

BE SURE TO RESET THE SALT MONITOR, PAGE 10.

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. 9. 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's most 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 it.

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

regeneration. If it becomes plugged with sand, silt, dirt, etc., the softener will not work and you will get hard water.

To get to the nozzle and venturi, remove the softener top cover. Be sure the softener is in service cycle (no water pressure at nozzle and venturi), then turn off the cap from the nozzle and venturi housing. Do not lose the large o???ring seal??? Lift out the screen support and screen, then 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.

Carefully replace all parts in the correct order. Lubricate the o9ring seal with silicone grease or Vaseline and place in position. Install and tighten the cap, by hand only. Do not overtighten and break the cap or housing.

IRON FROM THE RESIN BED

Your water softener takes hardness minerals (cal9 cium and magnesium) out of the water. Also, it can control some ???clear water" iron. See maximum allowed in the specifications on page 19. 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. Sears has resin bed cleaner, Item No. 42934426 for this. Clean the bed at least every 6 months. If iron shows up in the soft water before 6 months, clean more often. Printed instructions are on the resin bed cleaner bottle.

AUTOMATIC ELECTRONIC DIAGNOSTICS

The face plate computer has a self7diagnostic function for the electrical system (except input power and water meter). The computer monitors the electronic components and cir7

cuits for correct operation. If a malfunction occurs, an error code appears in the face plate display.

The chart below shows the error codes that could appear, and the possible defects for each code.

While an error code appears in the display, all face plate buttons are inoperable except the SELECT button. SELECT remains operational so the service person can make the MANUAL INITIATED ELEC7 TRONIC DIAGNOSTICS (below) to further isolate the defect, and check the water meter.

PROCEDURE FOR REMOVING ERROR CODE FROM FACE PLATE: 1. Unplug transformer 2. Correct defect 3. Plug in transformer 4. Wait for 6 minutes. The error code will return if the defect was not corrected.

MANUAL INITIATED ELECTRONICS

DIAGNOSTICS

1.To enter diagnostics, press the SELECT button and hold for 3 seconds.

You will see the following display, showing valve cycle position, position switch status (open or closed), and turbine operation.

position switch

indicator (open) turbine count (no water flowing)

TURBINE OPERATION: If no water is flowing through the softener, the turbine indicator displays 3 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???t get a reading in the display, with facuet 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 plumbing 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 1 position to another, the indicator will show the switch closed . A defect is probable if indications vary from this pattern.

VALVE POSITION INDICATORS: Depending on the valve position, the following indicators show in the display:

Serv . . . . . . . . . service

Fill . . . . . . . . . . . fill

Brine . . . . . . . . . brining/brine rinse

Bkwsh . . . . . . . . backwash

Rinse . . . . . . . . fast rinse

When the valve is rotating from 1 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 face plate is left in a diagnostic display (or a flashing display when setting times or hardness), present time automatically returns if a button is not pressed within 4 minutes. To return to the diagnositc display, repeat step 2.

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 face plate.

???Press the UP button to display the number of days this face plate has had electrical power applied.

???Press the DOWN button to display the number of regenerations initiated by this face plate since the SR code number was entered.

2.Press the ON/OFF8HOLD 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.

3.Press and hold the SELECT button for 3 seconds until???

...SR31 shows.

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

SR31 does show 9 Press the SELECT button to return the present time display.

To change SR number 9 Press the UP or DOWN button until SR31 shows. Then, press the SELECT button and reset the timer??? page 6.

FACE PLATE REPLACEMENT: BE SURE THE VALVE IS IN

SERVICE POSITION (OBSERVE VALVE CYCLE INDICATOR)

WHEN REPLACING THE FACE PLATE.

If, after installing and programming the replacement face place, the valve is not in service position, do the following to assure correct cycle orientation, or timing, between the face plate and valve.

Use the MANUAL ADVANCE procedures, page 23. With the RECHARGE NOW button, advance through the recharge cycles until the valve stops in service position, and RE8 CHARGE no longer flashes in the timer.

NOTE: The valve motor may automatically drive through several valve positions while searching for service. If an er8 ror code occurs, unplug the transformer, then plug in again.

MANUAL ADVANCE REGENERATION CHECK

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 diagnostics.

NOTES: The face plate 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 ON/OFF2HOLD button and hold in for 3 seconds. *RECHARGE and Fill begin to flash as the softener enters the fill cycle of regeneration. When Fill is on steady, remove the brinewell cover and, using a flashlight, observe fill water entering the tank.

*NOTE: If the CLEAN feature is set to ON, a cleaning backwash (CLEAN and Bkwsh or Rinse flashes in the display, along with the minutes of the clean cycle remaining), precedes the recharge.

a.If water does not enter the tank, look for an ob2 structed nozzle, venturi, fill flow plug, brine tub2 ing, or brine valve riser pipe.

CYCLE FLOW RATES (GALLONS PER MIN.)

2.After observing fill, press the ON/OFF2HOLD button 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 liquid level.

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

a.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.

3.Again press ON/OFF2HOLD to move the soften2 er into backwash. Look for a fast flow of water from the drain hose.

a.An obstructed flow indicates a plugged top dis2 tributor, backwash flow plug, or drain hose.

4.Press ON/OFF2HOLD to move the softener into fast rinse. Again look for a fast drain flow. Allow the softener to rinse for a few minutes to flush out any brine that may remain in the resin tank from the brining cycle test.

5.To return the softener to service, press ON/OFF2 HOLD.

5B.ROTARY VALVE SERVICE

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 the 3 hex head screws (see A in drawing) 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 completely disassemble.

SERVICING THE VALVE

Inspect all o7rings, seals and gaskets for wear or defects.

Inspect the bottom surface of the rotor and disc 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 o7rings and seals with FDA approved silicone grease. To install the rotor seal, first place the seal into the valve groove, rounded side down (see cross7section). 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 2 o7rings and the wave washer onto the rotor and disc. Then center the rotor and disc, 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 criss7cross pattern. If a torque wrench is available, torque to 30740 inch pounds.

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.

SERVICE CYCLE

from Valve Inlet (hard water)

resin bed

Hard water enters the valve inlet port. Internal valve porting routes the water down and out the top distributor, into the resin tank. Hard water is softened as it passes through the resin bed, then enters the bottom distributor. Soft water flows back into the valve and out the valve outlet, to the house soft water pipes.

To begin a regeneration, the electroic timer energizes the circuit to the valve motor. The valve motor rotates the rotor and disc and the valve cam until the position switch lever drops, to open the motor circuit and position the valve in FILL. As the rotor and disc rotates, the port opens for SOFT water fill through the venturi. Fill flow continues to the brine valve, and into the salt storage tank. Soft water is still available to the house lines.

brine from salt stor- age tank

After fill, timer/switch action allows the motor to turn the rotor and disc into BRINING position. Water flow is directed to the nozzle. Suction, created by the nozzle and venturi, draws brine from the salt storage tank and injects it into the resin bed via the bottom distributor. Flow continues out the top distributor and to the drain. Hard water is available at the valve outlet.

When the brine valve closes to end brine draw, water flow continues in the same directions to slowly RINSE brine from the resin bed and to the drain.

BACKWASH CYCLE

drain

Timer/switch action again allows the motor to turn the rotor & disc to place the valve in BACKWASH, stopping water flow to the nozzle. Water is routed down and out the bottom distributor, up through the bed, and out the top distributor to the drain. The fast flow (controlled by a flow plug in the drain fitting) flushes dirt, sediments, iron deposits, remaining brine and hardness to the drain.
