A. SAFETY GUIDES

•Read all steps, guides and rules carefully before

installing and using your new water softener. Follow

all steps exactly to correctly install. Failure to follow

them could cause personal injury or property damage.

Reading this book will also help you to get all of the

benefits from your water softener.

•Your water softener will remove hardness minerals

and "clear water" iron* from water, up to the limits

shown on page 4-1. It will not remove other types of

iron, acids, tastes and odors, etc. It will not purify pol-

luted water or make it safe to drink.

•Protect the softener and piping from freezing. Dam-

age from freezing voids the softener warranty. See

page 3-3.

CAUTIONS

PLEASE READ AND COMPLY WITH THE FOLLOWING

GUIDES TO PREVENT DAMAGE TO THE SOFTENER

OR OTHER PROPERTY, PERSONAL INJURY, OR POS-

SIBLE FATAL SHOCK.

•THIS SOFTENER WORKS ON 24 VOLTS ONLY. BE

SURE TO USE ONLY THE TRANSFORMER INCLUDED,

AND PLUG IT INTO A NOMINAL 120V, 60 CYCLE

HOUSEHOLD OUTLET THAT IS GROUNDED AND

PROPERLY PROTECTED BY AN OVERCURRENT DE-

VICE SUCH AS A CIRCUIT BREAKER OR FUSE. IF

TRANSFORMER IS REPLACED, USE ONLY THE AU-

THORIZED SERVICE, CLASS II, 24 VOLT, 10 VA

TRANSFORMER.

•Unplug the transformer right away if the power

cable should become damaged or frayed. Make re-

pairs, or replace transformer, before plugging back

California Efficiency Requirement

Your Kenmore Water Softener has a "High Effi-

ciency" feature with an "ON" or "OFF" setting.

This softener setting is shipped in the "OFF"

position, which utilizes the maximum rated ca-

pacity while most often achieving 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.

If you wish to turn the Salt Efficiency feature

"ON" (_ icon will show in display), follow the

instructions in the Faceplate Timer Features, Sec-

tion 2 of this manual.

NOTE: Codes in the state of Massachusetts require installation

by a licensed plumber. For installation, use plumbing code

248- CMR of the Commonwealth of Massachusetts,

D. SANITIZE THE

Care is taken at the factory to keep your water soft-

ener 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 (i9

when installing.

_The first time you sanitize your softener, be sure

to do all steps in the installation manual, and on

pages 1-2, 1-3 and 1-4 of this manual first.

Note: Be certain the bypass valve is pulled out

to "service" position.

_Lift the salt hole cover and use a pail to fill the

salt storage tank with up to 3 gallons of water.

_1 Remove the brinewell cover (FIG. 3) and pour

about 3/4 ounce, or 1 to 2 tablespoons, of com-

mon 5.25%, unscented, household bleach (Clo-

fox, Linco, BoPeep, White Sail, Eagle, etc.) in the

softener brinewell. Replace the brinewell cover.

D Press the RECHARGE button and holdfor 3 se-

conds to start a recharge. This first recharge does

several things.

• It draws the bleach into and through the softener

to sanitize 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 2-4) for ser-

vice and flushes residual chlorine from the soften-

er.

Notes:

This recharge takes about 2-1/2 or 2- 3/4 hours, de-

pending on the salt type setting (page 1-4).

You can sanitize the softener with or without salt

in the storage tank.

Brine (salt dissolved in water) is needed for each and

every regeneration. The water for making brine is me-

tered into the salt storage tank by the softener.

You must keep salt in the tank, but because the wa-

ter softener is very efficient, it is not necessary to

keep it full. Especially in humid areas, it is best to

fill the storage tank one quarter to one half full, and

to refill it more often. Salt bridging (see page 3-1) oc-

curs more often when conditions are humid.

ADDING SALT TO THE STORAGE TANK

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 con-

tent. It is recommended to use Sears Resin Bed Clean-

er 42- 34426, for periodic treatments to keep your resin

bed clean. This is available at your local Sears store.

Use 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 adding salt, be sure the brinewell cover is in

place on the top of the bfinewelt. It is recommended to

set the salt monitor system, although it is not required

for proper operation (see page 2-1).

Note: The salt monitor system, page 2-1, 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.

If you choose Potassium Chloride (KC1) as a regener-

ant, following these suggestions will help give you

years of maintenance free service.

1) Place only one bag of KC1 in your softener at a time

(the salt storage tank should contain no more than 60

pounds of KC1 at any one time).

2) A softener using KC1 should not be placed in areas

with temperature fluctuations and high humidity

(KC1 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 KC1 salt setting you

must increase your hardness setting by 25% to ensure

continuous soft water as in example below.

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 so-

dium 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.

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 so-

dium and other drinking water contaminants.

EXTRA RECHARGE

Sometimes, a manually started

regeneration (recharge) may be

desired, or needed. Two exam-

ples are:

- You have used more water than

usual (guests visiting) and you

may run out of soft water before

the next timer started regenera-

tion.

- You did not refill the softener

with salt before it was gone. After

you refill with salt:

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.

I1_ RECHARGE NOW [i°_] _7 -_nn_'_'L0

Press the RECHARGE button _,_G_

and hold until *RECHARGE, Serv ..........

and Fill begin to flash in the display. Upon reaching

fill, the first cycle of regeneration, the flashing Serv

goes off and Fill is on steady. RECHARGE continues

to flash. This regeneration will last for about 2

hours. After the 2 hours, you will have soft water

again.

*Note:

If the CLEAN feature is set to ON, a cleaning back-

wash (CLEAN and Bkwsh or Rinse flashes in the dis-

play, along with the minutes of the clean cycle re-

maining) precedes the recharge.

charge time. Press and release the RECHARGE but-

ton once more if you decide to cancel the regenera-

tion, and RECHARGE TONIGHT will not flash in

the display.

I1_ SALT MONITOR SYSTEM

The face plate timer has a low salt monitor with an

indicator light to remind you to add salt to the stor-

age tank. To set this monitor system:

_1_ Lift the salt hole cover and level the salt in the

storage tank.

mThe salt level decal on the brinewell inside the

tank, has numbers from 0 to 8 (see drawing be-

low). Observe the number the leveled salt is at

or closest to.

mNow, press the SALT LEVEL ADJUST button

until black bars display up to the salt level num-

ber. For example, the pictures below show the

salt level at 6.

E!Finally, set the level you want the low salt indi-

cator light to come on. Press the SIGNAL LIGHT

ADJUST button until a (÷) shows opposite this

number. In the example below, the light will

come on 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 (see note on page 1-6).

_If you wish to turn the salt monitor off, press the

SIGNAL LIGHT ADJUST button until OFF

shows above.

Note:

Your salt monitor is an estimate of your salt level; ac-

curacy depends on the type of salt used and other

regeneration characteristics.

The ultra cleansing feature keeps larger particles of

sediment from entering the home's plumbing sys-

tem. As water passes through the softener, the larg-

er sediment particles are collected in the integrated

basket and then rinsed to the drain before each re-

generation. The ultra cleansing feature provides

added protection for water-using appliances by re-

ducing the chance of larger particles entering the

various product's valves and screens.

An extra backwash will be pre-programmed into

the electronics by the factory (see "Clean Feature" in

Section 2 "Faceplate Timer Features" in this manu-

al). This extra backwash will help keep the ultra

cleansing feature screen clean.

Important: The ultra cleansing feature is not in-

tended to replace pretreatment filtration. For prob-

lem water applications, additional sediment filtra-

tion is recommended.

Sears offers a full- line of dedicated sediment filtra-

tion products including the Whole Home Filter and

Automatic Clarifying Filter.

B. SOFT WATER SERVICE and REGENERATION

SERVICE

When the softener is giving you soft water, it is

called "Service". During service, hard water comes

from 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. 5). As

hard water passes through the bed, each bead at-

tracts 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 miner-

als they can, and cleaning with salt brine is needed.

This cleaning is called regeneration or recharge. Re-

generation is started at 2:00 a.m. by the electronic

timer (see page 2-6). It takes place in 5 stages or

cycles. These are:

[] FILL [] BACKWASH

[] BRINING [] FAST RINSE

[] BRINE RINSE

Note:

If the Clean feature is set to ON, additional back-

wash and fast rinse cycles occur before the fill cycle.

[] FILL: Salt, dissolved in water, is called brine.

Brine is needed to dean 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. 6. 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.

B. 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 service water used between regen-

erations,

- -the amount of resin in the softener,

--how fast the brine goes through the bed.

The nozzle and venturi (FIG. 7) 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 miner-

als 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.

[] 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. 9).

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.

B. SOFT WATER SERVICE and REGENERATION

AUTOMATIC BYPASS

During the brining, brine rinse and backwash cycles

of regeneration, HARD water goes through the soft-

ener valve and to the house pipes. If a faucet is

opened, hard water is there for your needs. Howev-

er, you should not use hot water, if possible, because

the water heater will refill with hard water. The soft-

ener, as factory programmed, 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 re-

charge time to 12:00 AM or 1:00 AM (page 1-4).

Then regeneration will start and end that much ear-

lier 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 soft-

ener valve outlet. As water flows through the meter,

it sends electric pulses to the computer. The com-

puter changes the pulses to a measure in gallons of

water.

COMPUTER--The computer is part of the face-

plate timer circuit board. It is programmed to know

the softener's capacity (how many grains of hard-

ness minerals it will take out of the water before a re-

generation is needed). When starting the softener,

page 1-4, 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 al-

ways adjusts this pattern to your water using hab-

its. 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 re-

moved. 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. When

the regeneration begins, *RECHARGE or RE-

CHARGE TIME REMAINING flashes during the re-

generation.

* Note:

If the CLEAN feature is set to ON, a cleaning back-

wash (CLEAN and Blczvsh or Rinse flashes in the dis-

play, along with the minutes of the clean cycle re-

maining), precedes the recharge.

WHEN TO ADD SALT: The Salt

Monitor System (see page 2-1)

will turn the low salt light on to

warn you when to refill with salt.

Check for a low salt light a few

weeks after you install the soften-

er, and every week after that. Add

salt 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. After filling, reset the Salt Monitor Sys-

tem, page 2-1.

Note:

You will have a loss in softening capacity and may

get partly hard water if less than 10 inches (salt mon-

itor level 2) of salt is in the storage tank.

PLEASE SEE PAGE 1-6 FOR SALT FILLING DIRECTIONS.

BE SURE TO RESET THE SALT MONITOR, PAGE 2-1.

SALT BRIDGE

Sometimes, a hard crust or salt bridge forms in the

salt storage tank. It is usually caused by high hu-

midity 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 wa-

ter 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. 10. 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 the tank.

B. KEEPING THE WATER SOFTENER CLEAN

NOZZLE & VENTURI

A clean nozzle and venturi (FIG. 11) is a must for the

softener to work right. This small unit moves brine

from the salt storage tank to the resin tank during re-

generation. 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).

1) Turn off the cap from the nozzle and venturi hous-

ing.

2) Lift out the screen support and screen, do not lose

the Im_e o-ring seal.

3) 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. Lu-

bricate the o-ring seal with silicone grease or Vase-

line and place in position. 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 (cal-

cium and magnesium) out of the water. It can also

control some "clear water" iron. See maximum al-

lowed in the specifications on page 4-1. With clear

water iron, water from a faucet is clear when first

put into a glass. After 15 to 30 minutes, the water be-

gins 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 fil-

ter 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, Item No. 42-34426 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.

C. PROTECT THE WATER

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:

_[I Close the shut-off valve on the house main wa-

ter pipe, near the water meter or pressure tank.

_! Open a faucet in the soft water pipes to vent

pressure in the softener.

_ Refer to FIG. 14 on page 4-1. 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. Re-

move the salt hole cover and the main cover.

Take off both drain hoses.

_Carefully remove the large holding clips at the

softener inlet and outlet (see Key No. 67, on page

6-5). Separate the softener from the copper

tubes, or from the bypass valve.

SOFTENER FROM FREEZING

Drain All Water From Softener

_€_ Remove the brinewell cover and disconnect the

drain wood block

brine valve tubing at the nozzle and venturi as-

sembly (see page 3-2). Lift the brine valve out of

the brinewell. Tip the brine valve upside down

to drain water.

Looking at FIG. 12, 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.

D. CHECKLIST ... TO HELP YOU SAVE MONEY

If your water softener fails to work, make the following easy checks. Often, you will find what's wrong your-

self and you won't have to call and wait for service. If you do not find anything wrong, while making the

checks, and your softener still does not work, call your Sears Service Department.

Note:

1. Also read ERROR CODE, page 2-3.

2. If an error code is not displayed, press and hold the SELECT button until the display changes. Then, press

the SELECT button again and hold until a flashing SR code appears. It must show SR33. If any other number

shows, the face plate computer is working on incorrect input and would probably be the cause of the problem.

To set SR33, press either the UPI2_ or DOWN[_ button. When correct model code shows, press SELECT to

return a flashing 12:00 AM display. Reset the present time, hmdness numbe_, etc., pages 1-3 and 1-4.

Avoid using hot water during this time because

the water heater refills with hard water (see

Automatic Bypass, page 2-6).

Ask your Sears retail store for a new water

analysis. Then make a new hardness number

setting (page 1-4).

Check for kinks, bends or obstructions (see

page 16 in your installation manual).

placement timer PWA, the valve is not in ser-

vice position, do the following to assure correct

cycle orientation, or timing, between the face-

plate and valve.

Use the MANUAL ADVANCE procedures,

page 5-4. With the RECHARGE NOW button,

advance through the recharge cycles until the

valve stops in service position, and RE-

CHARGE no longer flashes in the display.

NOTE: The valve motor may automatically

drive through several valve positions while

searching for service. If an error code occurs,

unplug the transformer, then plug in again.

A. TROUBLESHOOTING

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 diag-

nostics.

Notes:

The faceplate display must show a steady time (not

flashing). If an error code shows, first press the SE-

LECT button to enter the diagnostic display.

_ Press the RECHARGE button and hold in for 3

seconds. *RECHARGE and Fill begin to flash (or

clean backwash begins, if set) as the softener en-

ters 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 back-

wash (CLEAN and Bkzosh or Rinse flashes in the dis-

play, along with the minutes of the clean cycle re-

maining), precedes the recharge.

a. If water does not enter the tank, look for an ob-

structed nozzle, venturi, fill flow plug, brine tubing,

or brine valve riser pipe.

CYCLE FLOW RATES (GALLONS PER MIN.)

FILL (flow to salt storage tank) 0.3 (1.1 liters)

BRINING '_ .22 (.83 liters)

BRINE RINSE I (flow .15 (.57 liters)

MAX. BACKWASH drain) 2.0 (7.6 liters)

MAX. FAST RINSE 2.0 (7.6 liters)

_ After observing fill, press the RECHARGE 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 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. See page

3-2

...nozzle and venturi not seated properly on gasket.

See page 3-2

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

...defective nozzle and venturi seal. See page 3-2

...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.

_1_ Again press RECHARGE to move the softener

into backwash. Look for a fast flow of water from

the drain hose.

a. An obstructed flow indicates a plugged top dis-

tributor, backwash flow plug, or drain hose.

_ Press RECHARGE 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.

_To return the softener to service, press RE-

CHARGE.

B. ROTARY VALVE SERVICE

Before working on the valve, turn off the water sup-

ply and disconnect from electrical power. TO RE-

LIEVE 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 completely disassemble.

SERVICING THE VALVE

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

fects.

Inspect the bottom surface of the rotor for scratches,

chips or wear.

Then, turn the rotor (clockwise only) to service posi-

tion. 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.

. __otor

motor plate

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 posi-

tion. Lubricate ALL o-rings and seals with FDA ap-

proved 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, care-

fully 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 tight-

ening the screws, install the valve cam and gear.

To begin a regeneration, the electronic 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.

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.

Timer/switch action again allows the motor to turn

flow (controlled by a flow plug in the drain fitting)

flushes dirt, sediments, iron deposits, remaining brine

and hardness to the drain.
