1A. 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 dam-

age. Reading this book will also help you to get all of

the benefits from your water softener.

•Your water softener will remove hardness miner-

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

shown on page 19. It will not remove other types of

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

polluted water or make it safe to drink.

•Protect the softener and piping from freezing.

Damage from freezing voids the softener warranty.

See page 17.

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, instal-

ling 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 all 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.

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

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

common 5.25% household bleach (Clorox, Lin-

co, BoPeep, White Sail, Eagle, etc.) in the

softener brinewell.

,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

softener to sanitize it.

-- It fills the salt tank to the water level need-

ed.

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

-- It prepares the resin bed (see page 12) for

service.

NOTES:

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

depending on the salt type setting (page 7).

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 pe-

riodic disinfecting.

SECTION 1 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 20. 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

half-full, 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.

ADD SALT

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 Kenmore Drinking Water

System that will remove or reduce in excess of 90%

of the sodium and other drinking water contami-

nants.

You have now finished the water softener start up. After the sanitizing recharge, on

page 8, the softener will be giving you soft water.

SECTION 2 HOW YOUR WATER SOFTENER WORKS

2A. FACEPLATE TIMER FEATURES

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.

RECHARGENOW

• Press the ON/ OFF-HOLD [ ii°_l_ -w,rlr'wPM

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

backwash (CLEAN and Bkwsh or Rinse flashes in

the display, along with the minutes of the clean

cycle remaining) precedes the recharge.

RECHARGETONIGHT

• Press and release (do not :o_1 q,,-nnP.

and the softener begins regen-

eration at the next preset recharge time. Press

and release the ON/OFF-HOLD button once

more if you decide to cancel the regeneration,

and 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.

oThe 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.

oNow, 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.

oFinally, 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 SIGNAL LIGHT

ADJUST button until OFF shows above.

NOTE:

For accurate salt monitor operation, always use

nugget or pellet water softener salt. See page 9.

correct time for about 12 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.

ERROR CODE

An error code could appear in _-F F I

the face plate display if a prob-

lem occurs in the softener elec-

tronics. If you see an error code

instead of the present time of day, please call your

local Sears Service Department for service.

SECTION 2 HOW YOUR WATER SOFTENER WORKS

2B. 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. 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 hold all of the

hardness minerals they can, and cleaning with salt

brine is needed. This cleaning is called regenera-

tion 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:

[] 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

[-2]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.

[3]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.

SECTION 2 HOW YOUR WATER SOFTENER WORKS

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 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 programmed, regen-

erates from 2:00 AM to about 4:00 AM, 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 recharge

starting time. 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.

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 pulses 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, 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 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 set) it will schedule a

regeneration. RECHARGE TONIGHT displays un-

til the regeneration begins. When the regeneration

begins, TONIGHT goes off and *RECHARGE or

RECHARGE TIME REMAINING flashes during

the 2 hour regeneration.

* NOTE:

If the CLEAN feature is set to ON, a cleaning

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

WHEN TO REFILL WITH SALT: The Salt Monitor

System (see page 10) 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

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. After filling, reset the Salt Moni-

tor System, page 10.

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.

SECTION 3 CARE OF YOUR SOFTENER

3B. KEEPING THE WATER SOFTENER CLEAN

COVERS

To keep your new Kenmore 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 & VENTURI

A clean nozzle and venturi (FIG. 10) 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 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 o-ring 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 (cal-

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. 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.

SECTION 3 cAREoFYourso .ER

30. 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.

Open a faucet in the soft water pipes to vent

pressure in the softener.

Refer to FIG. 12 on page 19. 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

softener inlet and outlet (see Key No. 69, on

page 30). Separate the softener from the copper

tubes, or from the bypass valve.

Remove the brinewell cover and disconnect the

brine valve tubing at the nozzle and venturi

assembly (see page 30). Lift the brine valve out

of the brinewell. Tip the brine valve upside

down to drain water.

DRAIN WATER FROM THE

SOFTENER

drain wood block

Looking at FIG. 11, 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.

SECTION 3 CARE OF YOUR SOFTENER

3D. HELPFUL HINTS 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

yourself 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.

NOTES:

1. Also read ERROR CODE, page 11.

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 HF code appears. It must show HF31. If any other num-

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

problem. To set HF31, press either the UP [] or DOWN[] button. When HF31 shows, press SELECT to

return a flashing 12:00 AM display. Reset the present time, hardness number, etc., pages 6 and 7.

PROBLEM

No soft water

CAUSE

No salt (or salt bridged) inthe storage tank

Transfomer unplugged at the wall outlet,

or power cable leads loose, fuse blown,

circuit breaker popped, or circuit switched

off.

Manual bypass valve(s) in bypass position

Dirty, plugged or damaged nozzle &

venturi

Valve drain hose plugged

Hardness number setting too low

Using hot water when softener is

water supply

CORRECTION

Refill with salt, or break the salt bridge (page

15). Press ON/OFF-HOLD (RECHARGE

NOW) button and hold for 3 seconds to start a

regeneration (see page 10).

Check for loss of power due to any of these

and correct. With the power back on, look at

the time display and read PROGRAM

MEMORY, page 11.

Look at FIG. 12 on page 19. Move the stem in

a single valve to service. In a 3-valve bypass,

open the inlet and outlet valves, and be sure to

fully close the bypass valve.

Take apart and clean or replace damaged

parts (see page 16).

The drain hose must not have kinks, sharp

bends, or be raised too high above the

softener (see page 16 in your installation

manual).

Press and release the SELECT button until

HARDNESS shows in the display. Read the

hardness number in the display and be sure

the same grains per gallon number is shown

on your water analysis report. See page 7 to

reset. Press and release the SELECT button

until the present time shows in the display.

Avoid using hot water during this time because

the water heater refills with hard water (see

Automatic Bypass, page 14).

Ask your Sears retail or catalog store for a new

water analysis. Then make a new hardness

number setting (page 7).

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

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 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 wave washer bearing, the wave washer,

and 2 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.

Lubricate the gear on the motor, and the valve cam
