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.

play. Note: You must set salt level each time salt is
added to the water softener.
•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 pow-
er comes on again, you have to reset the present
time only if the display is flashing. The HARD-
NESS, RECHARGE TIME and SAUF LEVEL 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.
•EFFICIENCY MODE
When this feature is ON, the wa-
ter softener will operate at salt ef-
ficiencies of 4000 grains of hard-

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 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.

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.
ELECTRONICS
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.

A. SALT: ADDING TO STORAGE TANK, SALT BRIDGE
S
C
T
N
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.

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.

[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 worm call the Kenmore Water Line at 1-800-426-9345.
Note:
1. Also read ERROR CODE, page 2-1.
