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, installing and operating,
baaeria 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 aU 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.
3. Remove the brinewell cover (FIG. 3) and pour
about 3/4 ounce of common 5.25% household
bleach (Clorox, Linco, BoPeep, White Sail, Eagle,
etc.) in the softener brinewell.
4. Press the ON/OFF-HOLD button and hold for 3
seconds to start a recharge. This first recharge does
several things,
SANITIZING THE WATER SOFTENER

— It draws the bleach into and through the soft
ener to sanitize it.
— It fills the salt tank to the water level needed.
— It gets all the air out of the resin lank.
— It prepares the resin bed (see page 13) for ser
vice.
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 wUb or with
out salt in the storage tank.
Recommended by the Water Quality Association. On
some water supplies, the water softener may need peri
odic disinfecting.

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 РЕПЕТ 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).
POTASSIUM CHLORIDE, alternate to salt: The design
of this softener allows for the use of potassium
chloride in place of salt (sodium chloride). Potassium
chloride does not add sodium to the water, and is
more ecologically friendly. Disadvantages include
higher cost, irregular dissolving factors, and the need
for longer softener regeneration times. If you do use
potassium chloride, see page 7 to set the timer
for its use.
FILL THE STORAGE TANK WITH SALT
FIG. 3
ADD SALT

Cover
Brinewell
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 potassium chloride, 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 16) 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.
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 contaminants. The
design of this softener also allows the use of potassium
chloride as an alternate to salt (see above, left).
Potassium chloride does not add sodium to the water.
You have now finished the water softener start up. After the sanitizing recharge, on
page 8, the softener will be giving you soft water.

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.
RECHARGE NOW
m Press the ON/OFF-HOLD
button and hold until RE
CHARGE, SERV and FILL begin
to flash in the display. Upon
reaching fill, the first cycle of re
generation, the flashing SERV
goes off and FILL is on steady. RECHARGE contin
ues to flash. This regeneration will last for about
2-1/2 to 2-3/4 hours. After this time, you will have
soft water again.
-NOTE:
If the CLEAN feature is set to ON, a cleaning backwash
precedes the recharge. CLEAN and Bkwsh or Rinse
flashes in the display, along with the minutes of the
clean cycle remaining.
FACEPLATE TIMER FEATURES
~\Œ’
SALT MONITOR SYSTEM
The faceplate 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 (press tank light button to light inside
of tank).
2. The 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,
3- Now, press the SALT LEVEL ADJUST button until
black bars display up to the salt level number. For
example, the piaures below show the salt level at
6.
4. Finally, 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 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.

SECTION 2
2B. SOFT WATER SERVICE AND REGENERATION
HOW YOUR WATER SOFTENER WORKS
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 attraaing 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 15). It takes place in 5 stages or cycles.
These are;

FAST RINSE
NOTE:
If the Clean feature is set to ON, additional backwash
and fast rinse cycles occur before the fill cycle.
REGENERATION
m 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
2B. SOFT WATER SERVICE AND REGENERATION
HOW YOUR WATER SOFTENER WORKS
¡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
2B. SOFT WATER SERVICE AND REGENERATION
HOW YOUR WATER SOFTENER WORKS
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, regenerates from 2:00 AM to
about 4:30 or 4:45 AM (depending on the salt type
setting, page 7), 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 m a
WATER METER, and E] a COMPUTER.
[H 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.
E] 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 until the regeneration begins.
When the regeneration begins, TONIGHT goes off
and *RECHARGE or RECHARGE TIME REMAINING
flashes during the 2-1/2 or 2-3/4 hour regeneration.
* 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.

3A. SALT...REFILLING STORAGE TANK/BREAKING A SALT BRIDGE
CARE OF YOUR SOFTENER
WHEN TO REFILL WITH SALT (or potassium chlo
ride): 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 ail
the salt before refilling. Without salt, you will soon
have hard water. After filling, reset the Salt Monitor
System, page 10.
PLEASE SEE PAGE 9 FOR SALT FILLING DIRECTIONS.
BE SURE TO RESET THE SALT MONITOR. PAGE 10.
SALT BRIDGE
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.
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, 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.

3B. KEEPING THE WATER SOFTENER CLEAN
CARE OF YOUR SOFTENER
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.
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.
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 (calcium
and magnesium) out of the water. Also, it can control
some “clear water” iron. See maximum allowed in the
specifications on page 20. 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 fitter 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
CARE OF YOUR SOFTENER
3C.
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.
3- Refer to FIG. 12 on page 20. 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.
4. Unplug the transformer at the wall outlet. Remove
the salt hole cover and the main cover. Take off
both drain hoses.
5. Carefully remove the large holding clips at the
softener inlet and outlet (see Key No. 69, on page
32). Separate the softener from the copper tubes,
or from the bypass valve.
KEEP THE SOFTENER FROM FREEZING
6. Remove the brinewell cover and disconnect the
brine valve tubing at the nozzle and venturi
assembly (see page 32). Lift the brine valve out of
the brinewell. Tip the brine valve upside down to
drain water.
FIG. 11
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.
8.
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.

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 12.
2. If an error code is not displayed, press and hold the #1 SELECT button until the display changes. Then, press the
#1 SELECT buEon again and hold until a flashing HF code appears. It must show HF32. 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
HF32, press either the UP 0 or DOWN 0 buEon. When HF32 shows, press #1 SELECT button to return a
flashing 12:00 AM display. Reset the present time, hardness number, etc., pages 6 and 7.

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 #1 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

SC .. WATER FLOW THROUGH THE SOFTENER VALVE
SERVICE TECH. INFORMATION
SERVICE CYCLE
Hard water enters the valve inlet port. Internal valve porting routes the water
down and out the top distributor, into the resin tank. Hard water is softened
as it passes through the resin bed, then enters the bottom distributor. Soft
water flows back into the valve and out the valve outlet, to the house soft
water pipes.
FILL CYCLE
To begin a regeneration, the elearonic 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 aaion allows the motor to turn the rotor and disc into
BRINING position. Water flow is direaed 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.
BACKWASH CYCLE

(hard water)
Timer/switch action again allows the motor to turn the
rotor & disc to place the valve in BACKWASH, stopping
water flow to the nozzle. Water is routed down and out
the bottom distributor, up through the bed, and out the
top distributor to the drain. The fast flow (controlled by
a flow plug in the drain fitting) flushes dirt, sediments,
iron deposits, remaining brine and hardness to the
drain.

FAST RINSE CYCLE

During FAST RINSE, the rotor & disc is positioned so water flow enters the
resin tank through the top distributor, and exits through the bottom
distributor, to the drain.
The electronic timer again energizes the motor to return the valve to service.
As the valve rotates, the position switch lever drops to open the circuit. The
valve remains positioned in service until the electronic timer initiates the
next regeneration.
