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.

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.

D. SANITIZE THE WATER SOFTENER

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 ;_;

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.

_J_ Lift the salt hole cover and use a pail to fill the

salt storage tank with 3 gallons of water.

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

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

mon 5.25%, unscented, household bleach (Clo-

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

softener brinewell. Replace the brinewell cover.

[]Press the RECHARGE button and hold for 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 2-3) for ser-

vice and flushes residual chlorine from the soften-

er.

Notes:

This recharge takes about 2-1/2 hours.

You can sanitize the softener with or without salt

in the storage tank.

SECTION1 WATER SOFTENER START UP

E. ADD SALT TO THE STORAGE TANK

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.

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 refillit more often. Salt bridging (see page 3-1) oc-

curs 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.

These salts may be used if your water supply has a

high iron content. It is recommended to use Sears

Resin Bed Cleaner 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 brinewell.

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

erant, 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 hu-

midity (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) You must increase your hardness setting by 25%

to ensure continuous soft water as in example be-

low.

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, and you drank 3 quarts of softened

water, you would consume 335 milligrams of so-

dium. 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.

SECTION2 HOW YOUR WATER SOFTENER WORKS

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 2-5). 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. 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.

SECTION2 HOW YOUR WATER SOFTENER WORKS

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 deans 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) 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 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 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.

SECTION2 HOW YOUR WATER SOFTENER WORKS

B. SOFT WATER SERVICE and REGENERATION

AUTOMATIC BYPASS

During the brining, brine rinse and backwash cydes

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 4:00 AM, a time when not much water

is used.

If you start your day earlier in the morning (prior ro

4:00 AM), you may want to change the recharge

starting time. Set the recharge time to 12:00 AM or

1:00 AM (page 1-4). 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.

m 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

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 soften-

er, page 1- 4, you set it for the grains per gallon (gpg)

hardness of the water.

'lb 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. When

the regeneration begins, RECHARGE NOW flashes

in the display during the regeneration.

SECTION3 CARE OF YOUR WATER SOFTENER

A. SALT: ADDING TO STORAGE TANK, SALT BRIDGE

WHEN TO ADD 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 (see

note on page 1-6). Never let the

softener use all the salt before re-

filling. Without salt, you will soon have hard water.

Note:

You will have a loss in softening capadty and may

get partly hard water if less than 10 inches of salt is

in the storage tank.

PLEASE SEE PAGE 1- 6 FOR DIRECTIONS ON ADDING SALT.

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.

'lb 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 large 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 and break

the cap or housing.

IRON FROM 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 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 doud 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). 'lb 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.

SECTION3 CARE OF YOUR WATER SOFTENER

C. PROTECT THE WATER 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:

[]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 vane. If you want water in the

house pipes again, reopen the shut-off valve on

the main water pipe.
