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, stor-  
age, installing and operating, bacteria could get  
into the softener. For this reason, sanitizing as  
follows is suggested¡ when installing.  
FIG. 3  
Brinewell  
Cover  
(remove and add  
about 3/4 oz. bleach)  
1. Lift the salt hole cover and use a pail or hose  
to fill the salt storage tank with at least 3  
gallons of water.  
2. 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 brine-  
well.  
Water,  
About 3 Gallons  
3. Press the ON/OFF-HOLD button and hold for  
3 seconds to start a recharge. This first re-  
charge 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 makes the resin bed (see page 11) ready  
for service.  
NOTES:  
This recharge takes about 2 hours.  
You can sanitize the softener with or with-  
out salt in the storage tank.  
¡
Recommended by the Water Quality Association. On  
some water supplies, the water softener may need  
periodic disinfecting. Sanitize with or without salt in the  
storage tank.

WATER SOFTENER START-UP  
SECTION 1  
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.  
FIG. 4  
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 21.  
NOTES:  
In humid areas, it is best to fill the storage tank  
half-full, and to refill it more often. Salt bridging  
(see page 14) occurs more often when conditions  
are humid.  
WATER SOFTENING SALT WITH IRON RE-  
MOVING 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 us-  
ing sodium chloride for regeneration add so-  
dium to the water. Persons who are on sodium  
restricted diets should consider the added so-  
dium 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 Sears Drinking Water  
System that will remove or reduce in excess of  
90% of the sodium and other drinking water  
contaminants.

TIMER “POWER-OUTAGE MEMORYIf  
electrical power to the timer goes off, the  
“memory” built into timer circuitry keeps all  
settings for 6 hours (minimum) or more. The  
display is blank and the softener will not  
regenerate. When electrical power comes on, 1 of  
2 things will happen.  
2. The display will show a time, but it will be  
flashing. The timer memory did not keep the  
time settings and they must be reset (page 6).  
The flashing display is to remind you to reset  
the timer.  
NOTE:  
1. The present time of day will show, meaning  
When power comes on, the flashing display  
returns to a time of 12:00 AM Sunday, then  
begins to keep time again. If you do not reset all  
time settings, the softener will regenerate 3 days  
each week. However, regeneration will most  
likely be on the wrong days and at the wrong  
time.  
the timer memory has kept all settings.  
NOTE:  
If the softener was in a regeneration when power  
was lost, it will now finish the cycle.  
If the softener was in a regeneration when power  
went off, the valve will return to service position  
without finishing the regeneration cycle. If your  
water tastes salty:  
- - use RECHARGE NOW (see page 9) to start  
another regeneration, or  
- - open 1 or more soft water faucets and allow to  
run until the salt taste is gone.

2B. SOFT WATER SERVICE AND REGENERATION  
SERVICE  
REGENERATION  
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. 7). 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.  
¡ FILL: Salt, dissolved in water, is called brine.  
Brine is needed to clean the hardness minerals  
from the resin beads. To make the brine, soft  
water flows into the salt storage area during the  
fill cycle as shown in FIG. 8.  
The length of the fill cycle is factory set to  
provide softening capacity for an average family.  
You can reset this time when “fine-tuning” the  
water softener, pages 18 through 20.  
FIG. 8 WATER FLOW THROUGH THE  
SOFTENER IN FILL  
After a period of time, the resin beads become  
coated with hardness minerals and they have to  
be cleaned. This cleaning is called recharge, or  
regeneration.

2B. 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:

resin bed lifted  
and expanded  
The nozzle and venturi (FIG. 9) makes the  
suction to take brine from the salt tank and put it  
into the resin tank. It keeps 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 goes 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.  
¤ 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. 11).  
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.

SECTION 2  
2B. SOFT WATER SERVICE AND REGENERATION  
AUTOMATIC BYPASS  
If you get up early in the morning and you can  
hear the softener regenerating, change the time  
setting. Set the recharge time to 12:00 AM or 1:00  
AM (page 18). 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.  
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 regener-  
ates from 2:00 AM to about 4:00 AM, (you can set  
anytime), a time when not much water is used.

CARE OF YOUR SOFTENER  
SECTION 3  
3A. SALT¼ REFILLING STORAGE TANK/BREAKING A SALT BRIDGE  
WHEN TO REFILL WITH 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. Never let the  
softener use all the salt before refilling. Without  
salt, you will soon have hard water.  
IMPORTANT:  
You will have a loss in softening capacity and  
may get partly hard water if less than 10 inches  
of salt is in the storage tank.  
PLEASE SEE PAGE 8 FOR SALT FILLING DIRECTIONS.  
SALT BRIDGE  
Sometimes, a hard crust or salt bridge forms in  
FIG. 12 A SALT BRIDGE  
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.  
Broom Handle  
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. 12. 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, its 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.

KEEPING THE WATER SOFTENER CLEAN  
COVERS  
NOTE:  
Never use cleaners having ammonia or abra-  
sives. They may scratch and dull the surface.  
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.  
NOZZLE AND VENTURI  
FIG. 13  
A clean nozzle and venturi (FIG. 13) 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.  
Cap  
O--ring Seal  
Screen Support  
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. Ifneeded, use a small brush to remove iron  
or dirt. Also check and clean the gasket, small  
screen and flow plug.

IRON FROM THE RESIN BED  
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, Stock 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.  
Your water softener takes hardness minerals  
(calcium and magnesium) out of the water. Also,  
it can control some “clear water” iron0see  
maximum allowed in the specifications on page  
21. 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

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 —  
FIG. 14 DRAIN WATER FROM 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. Looking at FIG. 16 on page 21, 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.  
7. Looking at FIG. 14, lay a piece of 2 inch thick  
board near the floor drain. Move the softener  
close to the drain. SLOWLY and CAREFUL-  
LY tip it over until the rim rests on the wood  
block with the inlet and outlet over the drain.  
Do not allow the softeners weight to rest on  
the inlet and outlet fittings or they will  
break.  
5. Carefully remove the large holding clips at  
the softener inlet and outlet (see Key No. 61,  
on page 34). Separate the softener from the  
adaptors or bypass valve.  
6. Remove the brinewell cover and disconnect  
the brine valve tubing at the nozzle and

valve out of the brinewell. Tip the brine valve  
upside down to drain out water.  
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.

1. Read “ERROR CODE”, page 9.  
2. If your water softener fails to work, make the following easy checks. Often, you will find whats  
wrong yourselfand you wont have to call and wait for service. If, after making the checks, your soften-  
er still does not work right, call your Sears Service Department, or call toll free, number  
1-800-426-9345 for telephone assistance.  
You can find the model number of your water softener on the rating decal, on the brine tank rim. See

HOW TO “FINE-TUNE” YOUR SOFTENER  
It is not hard to fine-tune your softener, but it  
does take a few minutes of your time to do it  
right. You may save up to 500 pounds or more of  
salt each year with proper tuning. Read the  
following carefully.  
TO SET THE TIMER FOR DAYS OF REGEN-  
ERATION AND FILL MINUTES, DO THE FOL-  
LOWING.  
NOTE:  
Remember, the timer is factory set for Monday,  
Wednesday and Saturday regenerations starting  
at 2:00 AM. Fill time is factory set for 8 minutes.  
To have soft water all the time, the softener must  
regenerate, or recharge a certain number oftimes  
in each 7 day period. How many times to  
regenerate (set the timer) depends on 3 things.  
1. SET DAYS AND TIME OF REGENERA-  
TION, OR RECHARGE  
1. The number of people in your home — tells  
you how much water is used.  
a. Press the RECHARGE TIME button © once  
to display the factory set regeneration days  
and starting time (flashing). To change the re-  
generation start time, do step b following.  
Otherwise go to step c.  
2. The grains per gallon (GPG)hardness ofyour  
water supply — listed on your water analysis  
report (see page 2 in your Installation Manu-  
al, or page 2 of this manual).  
FIG. 15  
NOTE:  
If your water supply contains iron, compensate  
for it by adding to the water hardness number.  
For example, assume your water is 15 gpg hard and  
contains2ppm iron. Add 5to thehardness number for  
each 1 ppm of iron. In this example, you would use 25  
for your hardness number.

3. How much salt is used each regeneration —  
determined by the length of the fill cycle (see  
pages 19 and 20).  
REGENERATION TABLE: The table (page 20)  
makes it easy fo you to pick the best regeneration  
and fill time setting to use.  
b. Press the SET/ CLEARbutton £ until the de-  
sired regeneration starting time shows in the  
display.  
Step 1 — Go down the side of the table to the  
number of persons in your family, or the number  
of people in the house using water.  
NOTE:  
Press SET/ CLEAR and quickly release to move  
the display ahead 1 hour at a time. Or, hold the  
SET/ CLEAR button to move the display ahead 2  
hours each second.  
Step 2 — Across the top of the table, find the  
column listing the grains per gallon hardness of  
your water, or hardness number for iron water.  
WRITE IN YOUR RESULTS HERE.  
Step 3 — Read across and down the table to find  
the point where steps 1 and 2 meet. At this  
meeting point, suggested days to regenerate,  
and fill cycle minutes needed are shown.

TROUBLESHOOTING  
AUTOMATIC ELECTRONIC DIAGNOSTICS  
The chart below shows the error codes that could  
appear, and the possible defects for each code.  
The face plate has a self-diagnostic function for the  
electrical system (except input power). The face plate  
monitors the electronic components and circuits for  
correct operation. If a malfunction  
occurs, an error code appears in the  
face plate display.  
While an error code appears in the display, all face  
plate buttons are inoperable except the SET button.  
The SET button remains operational so the service  
person can make the MANUAL ADVANCE DIAG-  
NOSTICS to further isolate the defect.

FACE PLATE REPLACEMENT: Be sure the valve is in service position (observe valve cycle indicator. . . see  
below) when replacingthe face plate.  
If, after installing and programming the replacement face place, the valve is not in service position, do the fol-  
lowing to assure correct cycle orientation, or timing, between the face plate and valve.  
Use the MANUAL ADVANCE procedures, below. With the RECHARGE NOW button, advance through the  
recharge cycles until the valve stops in service position, and RECHARGE no longer flashes in the timer.  
NOTE: The valve motor may automatically drive through several valve positions while searching for service.  
While the valve is ro-

Before working on the valve, turn off the water  
supply and disconnect from electrical power. TO  
RELIEVE 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 the 3 hex head screws  
(see A in drawing) 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 disassembe.  
SERVICING THE VALVE  
Inspect all o-rings, seals and gaskets for wear or  
defects.  
Inspect the bottom surface of the rotor and disc for  
scratches, chips or wear.  
screen  
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 2 o-rings and the wave washer onto the  
rotor and disc. Then center the rotor and disc, in the  
valve body, on the rotor seal.  
Lubricate the gear on the motor, and the valve cam  
gear with Molykote grease, or other high quality gear  
lubricant.  
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.  
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.  
Be sure to orient switch as shown, with lever toward  
the cam.

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.

To begin a regeneration, the solid state timer energizes the circuit to the valve motor. The  
valve motor rotates the rotor and discand 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 SOFTwater 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 slow-  
ly RINSE brine from the resin bed and to the drain.  
BACKWASH CYCLE

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 bot-  
tom 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, re-  
maining brine and hardness to the drain.

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 solid state timer again energizes the motor to return the valve to service, and as the  
valve rotates, the position switch lever drops to open the circuit. The valve remains posi-  
tioned in service until the timer initiates the next regeneration.
