NOTES:

This recharge takes about 2 hours.

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

Recommended by the Water Quality Association. On some water supplies, the water softener may need periodic disinfecting. Sanitize with or without salt in the storage tank.

8

Brine (salt dissolved in water) is needed for each and eveu regeneration. The water for making brine is metered into the salt storage tank by the softener.

However, you must keep tile 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 18.

NOTE:

In humid areas, it is best to fill the storage tank half-full, and to refill it more often. Salt bridging (see page 14) occurs more often when conditions are humid.

Water softening salt with iron removing addi- tives -- 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.

ADD SALT

Brinewell

Cover

Sodium Information: 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 2-1/2 slices of white bread.

Persons who are concerned about their drinking water should consider a Sears Drinking Water System that will remove or reduce in excess of 90% of the sodium and other drinking water contaminants.

2A.FACE PLATE TIMER FEATURES

EXTRA RECHARGE

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

aye:

--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 fight away, or you can set the timer to regenerate at the next 2:00 AM (or other preset recharge time). Do the following.

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 you water soft. However, regenerations may occur at the wrong time of clay until you reset the timer to the correct time of day.

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 and into the softener.

Inside of 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 ion-exchanging. 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 13). It takes place in 5 stages or cycles. These are:

[] 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.

2B. SOFT WATER SERVICE AND REGENERATION

EZ]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.

WATER FLOW THROUGH THE

SOFTENER IN BACKWASH

The nozzle and venturi (FIG. 6) make suction to move brine from the salt tank into the resin tank.

They keep the brine flow down tO a veI3r slow rate tO

get the best resin cleaning with the least salt.

[] BRINE RINSE: After all of the brine is sucked OUt of the salt tank, the brine valve closes. Water keeps flowing through the resin tank 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 length of time they take, relative to the fill cycle length.

E_]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.

2B. 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 ff)r 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 change this time.., see page 7). In most homes, 2-4 AM is a time when not much water is used, if any.

If you get up early in the morning and you can hear the softener regenerating, change the time setting. Set the recharge start time to ]2:00 AM or ] :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.

ELECTRONICS

Two m_dn parts of the softeneffs electronics are [] a WATER METER, and [] a COMPUTER.

[] WATER METER I 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 I The computer is part of the timer circuit board. It is programmed to know the softeneffs 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 groins per gallon (gpg) hardness of the water.

To find a regeneration pattern best for your needs, the computer uses: (]) 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 to provide you with soft water for the longest time, 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 regeneration starting time (2:00 AM, or as otherwise se0, it will schedule a regeneration.

_CtlARGE TONIG[IT displays until the regenera- tion begins. When the regeneration begins, TO- NIGHT goes off and I_CI_IARGE NOW flashes during the 2 hour regeneration.

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

WHEN TO REFILl, WITH SALT: Check the salt level a few weeks after you install the softener and every week after that. Refill when the storage tank is about 1/3 full. Never let the softener use all the salt before refilling. Without salt, you will soon have hard water.

IMPORTANT:

You will have a loss in softening capacity and

may get partly hard water if less than 10

inches of salt is in the storage tank.

PLEASE SEE PAGE 9 FOR SALT FILLING DIRECTIONS.

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, as shown. 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 the tank.

If the wrong kind of salt was the cause of the bridge, take it OUt. Then fill the tank with nugget or pellet salt only.

3B. KEEPING THE WATER SOFTENER CLEAN

COVERS

To keep your new Sears water softener looking nice, apply a coat of paste wax and repeat once a year. When dusty, wipe it with a damp cloth to keep it sparkling.

NOTE:

Never use cleaners having ammonia or abrasives.

They may scratch and dull the surface.

NOZZLE AND VENTURI

A clean nozzle and venturi (FIG. ] 0) 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.

TURI

Cap

, ---:: - i

\/

O-ring Seal _0

Screen Support

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, holding the housing tightly with I hand, turn the cap off. Do not lose the large o-ring seal. Lift out the screen support and screen, then the nozzle and venturi. Wash anti 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.

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

IRON FROM THE RESIN BED

Your water softener takes hardness minerals (cal- cium and magnesium) out of the water. Also, it can control some "clear water" iron. See maximum

allowed in the specifications on page ] 8. With clear water iron, water from a faucet is clear when first put into a glass. After ] 5 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, Stock No. 42-34426 for this. Clean the bed at least eve1T 6 months. If iron appears in the soft water before 6 months, clean more often. Printed instruc- tions are on the resin bed cleaner bottle.

3C. KEEP THE SOFTENER FROM FREEZING

If the softener is installed where it could freeze (summer cabin, lake home, etc.), you must drain all water from it to stop possible freeze damage. To drain the softener:

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 pressure in the softener.

e If a single bypass valve is installed, move the stem into bypass. See FIG. 12 on page 18. In a 3-valve bypass system, close the inlet and outlet valve and open the bypass valve. If you want water in the house pipes again, reopen the shut-off valve on the main water pipe.

4.Unplug the transformer at the wall outlet.

5.Remove the salt hole cover and the main cover. Take off both drain hoses.

6.Carefully remove the large holding clips at the softener inlet and outlet (see Key No. 6], on page 30). Separate the softener from the adaptors or bypass valve.

7.Remove the brinewell cover and disconnect the brine valve tubing at the nozzle and venturi assembly (see page 23). Lift the brine valve out of the brinewell. Tip the brine valve upside down to drain out water.

DRAIN WATER FROM THE

SOFTENER

8.Looking at FIG. ] ], 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.

... TO HELP YOU SAVE MONEY

If your water softener fails to work, make the following easy checks. Often, you will find what's wrong yourself and you won't have to call and wait for service. If, after making the checks, your softener still does not work right, call your Sears Service Department, or call toll free, number 1-800-426-9345 for telephone assistance.

NOTE:

1.Also read ERROR CODE, page ] 0.

2.If an error code is not dispIayed, press and bold the SELECT button until (example: 000- -) shows in the display. Then, press SELECT again and bold until an SR code appears. It must show SR 17. If any other SR

number shows, the softener computer is working on incorrect input and this would probably be the cause of the problem. To set SR 1.7, press either the UP (_ or DOWN[_buEon. Then, press SELECT to return a flashing 12:00 AM display, and reset the umer on page 6.

TO RELIEVE PRESSURE:

-3 VALVE BYPA,_S.. Close the inlet valve and (;)pen a soft water faucet. Then close the outlet valve and

(:)pen the bypass valve.

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

-,fEARS SPE(3AL BYPASS: Slide the bypass valve stem to bypass position. Loosen the 3 hex head screws (see A in drawing) toward the backside of the valve to allow pressure water to bleed out. Catch the 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 (:)-rings, 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 ()-rings and seals with FDA approved silicone grease. To install the rotor seal, first place the seal into the valve groove, rounded side down (see cross-section). 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 ()-rings 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)

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

5C. WATER FLOW THROUGH THE SOFTENER VALVE

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.

NOTES:

This recharge takes about 2 hours.

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

Recommended by the Water Quality Association. On some water supplies, the water softener may need periodic disinfecting. Sanitize with or without salt in the storage tank.

Brine (salt dissolved in water) is needed for each and eveu regeneration. The water for making brine is metered into the salt storage tank by the softener.

However, you must keep tile 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 18.

NOTE:

In humid areas, it is best to fill the storage tank half-full, and to refill it more often. Salt bridging (see page 14) occurs more often when conditions are humid.

Water softening salt with iron removing addi- tives -- 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.

ADD SALT

Brinewell

Cover

Sodium Information: 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 2-1/2 slices of white bread.

Persons who are concerned about their drinking water should consider a Sears Drinking Water System that will remove or reduce in excess of 90% of the sodium and other drinking water contaminants.

2A.FACE PLATE TIMER FEATURES

EXTRA RECHARGE

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

aye:

--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 fight away, or you can set the timer to regenerate at the next 2:00 AM (or other preset recharge time). Do the following.

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 you water soft. However, regenerations may occur at the wrong time of clay until you reset the timer to the correct time of day.

RECHARGE NOW

???Press the ON/OFF--HOLD

ERROR CODE

An error code could appear in the face plate display if a problem occurs in the softener electronics. If you see an error code instead of the time of clay, please call you local Sears Service Department for service.

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 and into the softener.

Inside of 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 ion-exchanging. 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 13). It takes place in 5 stages or cycles. These are:

[] 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.

EZ]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.

WATER FLOW THROUGH THE

SOFTENER IN BACKWASH

The nozzle and venturi (FIG. 6) make suction to move brine from the salt tank into the resin tank.

They keep the brine flow down tO a veI3r slow rate tO

get the best resin cleaning with the least salt.

[] BRINE RINSE: After all of the brine is sucked OUt of the salt tank, the brine valve closes. Water keeps flowing through the resin tank 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 length of time they take, relative to the fill cycle length.

E_]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.

2B. 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 ff)r 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 change this time.., see page 7). In most homes, 2-4 AM is a time when not much water is used, if any.

If you get up early in the morning and you can hear the softener regenerating, change the time setting. Set the recharge start time to ]2:00 AM or ] :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.

ELECTRONICS

Two m_dn parts of the softeneffs electronics are [] a WATER METER, and [] a COMPUTER.

[] WATER METER I 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 I The computer is part of the timer circuit board. It is programmed to know the softeneffs 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 groins per gallon (gpg) hardness of the water.

To find a regeneration pattern best for your needs, the computer uses: (]) 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 to provide you with soft water for the longest time, 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 regeneration starting time (2:00 AM, or as otherwise se0, it will schedule a regeneration.

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

WHEN TO REFILl, WITH SALT: Check the salt level a few weeks after you install the softener and every week after that. Refill when the storage tank is about 1/3 full. Never let the softener use all the salt before refilling. Without salt, you will soon have hard water.

IMPORTANT:

You will have a loss in softening capacity and

may get partly hard water if less than 10

inches of salt is in the storage tank.

PLEASE SEE PAGE 9 FOR SALT FILLING DIRECTIONS.

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, as shown. 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 the tank.

If the wrong kind of salt was the cause of the bridge, take it OUt. Then fill the tank with nugget or pellet salt only.

3B. KEEPING THE WATER SOFTENER CLEAN

COVERS

To keep your new Sears water softener looking nice, apply a coat of paste wax and repeat once a year. When dusty, wipe it with a damp cloth to keep it sparkling.

NOTE:

Never use cleaners having ammonia or abrasives.

They may scratch and dull the surface.

NOZZLE AND VENTURI

A clean nozzle and venturi (FIG. ] 0) 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.

CLEANING THE NOZZLE & VEN-

TURI

Cap

, ---:: - i

\/

O-ring Seal _0

Screen Support

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, holding the housing tightly with I hand, turn the cap off. Do not lose the large o-ring seal. Lift out the screen support and screen, then the nozzle and venturi. Wash anti 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.

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

IRON FROM THE RESIN BED

Your water softener takes hardness minerals (cal- cium and magnesium) out of the water. Also, it can control some "clear water" iron. See maximum

allowed in the specifications on page ] 8. With clear water iron, water from a faucet is clear when first put into a glass. After ] 5 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, Stock No. 42-34426 for this. Clean the bed at least eve1T 6 months. If iron appears in the soft water before 6 months, clean more often. Printed instruc- tions are on the resin bed cleaner bottle.

3C. KEEP THE SOFTENER FROM FREEZING

If the softener is installed where it could freeze (summer cabin, lake home, etc.), you must drain all water from it to stop possible freeze damage. To drain the softener:

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 pressure in the softener.

e If a single bypass valve is installed, move the stem into bypass. See FIG. 12 on page 18. In a 3-valve bypass system, close the inlet and outlet valve and open the bypass valve. If you want water in the house pipes again, reopen the shut-off valve on the main water pipe.

4.Unplug the transformer at the wall outlet.

5.Remove the salt hole cover and the main cover. Take off both drain hoses.

6.Carefully remove the large holding clips at the softener inlet and outlet (see Key No. 6], on page 30). Separate the softener from the adaptors or bypass valve.

7.Remove the brinewell cover and disconnect the brine valve tubing at the nozzle and venturi assembly (see page 23). Lift the brine valve out of the brinewell. Tip the brine valve upside down to drain out water.

DRAIN WATER FROM THE

8.Looking at FIG. ] ], 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.

9.Tip the bottom of the softener up a few inches

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

-,fEARS SPE(3AL BYPASS: Slide the bypass valve stem to bypass position. Loosen the 3 hex head screws (see A in drawing) toward the backside of the valve to allow pressure water to bleed out. Catch the 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 (:)-rings, 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 ()-rings and seals with FDA approved silicone grease. To install the rotor seal, first place the seal into the valve groove, rounded side down (see cross-section). 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 ()-rings and the wave washer onto the rotor and disc. Then center the rotor and disc, in the valve body, on the rotor seal.
