SAFETY GUIDES  
Read all steps, guides and rules carefully be-  
fore installing and using your new water softener.  
Follow all steps exactly to correctly install. Fail-  
ure 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 min-  
erals and “clear water” iron from water, up to the  
limits shown on page 18. 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 warran-  
ty. See page 16.

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,  
installing and operating, bacteria could get into  
the softener. For this reason, sanitizing as follows  
FIG. 2 ADD WATER

Cover  
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.  
(remove and add  
about 3/4 oz. bleach)  
2. Remove the brinewell cover (FIG. 2) and pour  
about 3/4 ounce of common 5.25% household  
bleach (Clorox, Linco, BoPeep, White Sail, Eagle,  
etc.) in the softener brinewell.

softener to sanitize it.  
Ċ It fills the salt tank to the water level

Ċ It gets all the air out of the resin tank.  
Ċ 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 withĆ  
out 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. 3 ADD 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 18.  
NOTE:  
In humid areas, it is best to fill the storage tank  
halfĆfull, and to refill it more often. Salt bridging  
(see page 14) occurs more often when conditions  
are humid.  
WATER SOFTENING SALT WITH IRON REMOVĆ  
ING ADDITIVES Ċ 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 2Ć1/2 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.

FACE PLATE TIMER FEATURES  
EXTRA RECHARGE  
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  
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.  
Sometimes, a manually started regeneration (reĆ  
charge) may be desired, or needed. Two examĆ  
ples are:  
-- You have used more water than usual (guests  
visiting) and you may run out of soft water before  
the next timer started regeneration.  
Even if the timer is incorrect after a long power  
outage, the softener works as it should to keep  
you water soft. However, regenerations may occur  
at the wrong time of day until you reset the timer  
to the correct time of day.  
-- 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.  
ERROR CODE

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. 4). As  
hard water passes through the bed, each bead  
attracts and holds the hardness minerals. This is  
called ionĆexchanging. 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, 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.  
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 13). It takes place in  
5 stages or cycles. These are:

SOFT WATER SERVICE AND REGENERATION  
BRINING: During brining, thebrineis moved  
from thesalt storagearea, into theresin tank.  
Inside the resin tank, brine cleans hardness  
minerals from the resin beads and they are  
dischargde out thedrain. How much brineis  
needed to clean the resin depends on:  
FIG. 7 WATER FLOW THROUGH THE  
SOFTENER IN BACKWASH  
-- the amount of resin in the softener,  
-- how fast thebrinegoes through thebed.  
Thenozzleand venturi (FIG. 6) makesuction to  
takebrinefrom thesalt 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  
theleast salt.  
BRINE RINSE: After all of thebrinegoes into the  
resin tank, the brine valve closes. Water keeps  
flowing thesameway it did during brining except  
the brine flow has stopped. Hardness minerals  
and brineflush from theresin tank to thedrain.  
Brining and brine rinse together vary in 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. 8).  
FIG. 6 WATER FLOW THROUGH THE  
SOFTENER IN BRINING AND  
BRINE RINSE  
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.

SOFTENER IN FAST RINSE  
BACKWASH: During backwash, water flows UP  
through theresin tank (FIG. 7) at a fast rateto flush  
iron minerals, dirt and sediments from the bed and  
to thedrain. Thebed lifts and expands for good  
cleaning.

2B.  
SOFT WATER SERVICE AND REGENERATION  
AUTOMATIC BYPASS  
ELECTRONICS  
Two main parts of the softener's electronics are  
a WATER METER, and a COMPUTER.  
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 regenerates from 2:00  
AM to about 4:00 AM, (you can change this time...  
see page 7), a time when not much water is used.  
WATER METER Ċ 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 Ċ The computer is part of the  
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.  
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 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.  
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 to provide you with soft  
water for the longest time, 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 NOW  
flashes during the 2 hour regeneration.

SALTREFILLING 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 9 FOR SALT FILLING DIRECTIONS.  
SALT BRIDGE  
Sometimes, a hard crust or salt bridge forms in the  
If the wrongkind of salt made the bridge, take it  
out. Then fill the tank with nugget or pellet salt

salt storage tank. It is usually caused by high  
humidity or the wrongkind 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.  
FIG. 9 SALT BRIDGE  
push tool into salt  
bridge to break  
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.  
1” – 2”  
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, 1or 2below the top height  
of the rim, as shown. 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.

KEEPING THE WATER SOFTENER CLEAN  
COVERS  
NOTE:  
To keep your new Sears 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.  
Never use cleaners having ammonia or abrasives.  
They may scratch and dull the surface.  
NOZZLE AND VENTURI  
FIG. 10 CLEANING THE NOZZLE & VEN-  
TURI  
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, holding the housing tightly with 1  
hand, turn the cap off. DO NOT LOSE THE LARGE  
OĆRING 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 oĆring seal with silicone grease or  
Vaseline and place in position. Install and tighten  
the cap, by hand only. Do not overĆtighten and  
break the cap or housing.

IRON FROM THE RESIN BED  
water iron, an iron filter or other equipment is  
needed. Your local Sears store has trained people  
to help you with iron water problems.  
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 18. 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  
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. 42Ć34426 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  
3C.  
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. 11 DRAIN WATER FROM THE  
SOFTENER  
1. Close the shutĆoff 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. If a single bypass valve is installed, move the  
stem into bypass. See FIG. 12 on page 18. In a  
3Ćvalve bypass system, close the inlet and  
outlet valve and open the bypass valve. If you  
want water in the house pipes again, reopen  
the shutĆoff valve on the main water pipe.  
7. 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.  
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. 61, on  
page 30). Separate the softener from the  
adaptors or bypass valve.  
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

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, after making the checks, your softener still does  
not work right, call your Sears Service Department, or call toll free, number 1-800-426-9345 for telephone  
assistance.  
NOTE:  
Also read ERROR CODE, page 10. If an error code is not dispIayed, press and hold the SELECT button until  
(example: 000- -) shows in the display. Then, press SELECT again and hold until an SR code appears. It  
must show SR21. If any other SR number shows, the softener computer is working on incorrect input and  
would probably be the cause of the problem. To set SR21, press either the UP or DOWN button. Then  
press select to return a flashing 12:00 AM display, and reset the timer, page 6.

TROUBLESHOOTING  
Keep this manual with your water softener. If repairs are needed, the service technician must have  
the information on the following pages. For telephone assistance, call toll free, 1-800-426-9345.  
ALWAYS MAKE THESE INITIAL CHECKS FIRST  
REMOVE THE TOP COVER AND SALT TANK COVER  
1. Does the time display show the correct time of day?  
6. Is there salt in the storage tank?  
- If display is blank, check power source to the  
softener.  
7. Is the brine tubing connected? (See water flow  
diagrams).  
- If time is flashing, power was off for over 6 hours. The  
softener resumes normal operation but regenerations  
occur at the wrong time.  
- If an error code (Example: Err 03) shows in the face  
plate display, go to AUTOMATIC ELECTRONIC DIAGĆ  
NOSTICS.  
8. Is the brine valve float set right? (See page 22).  
9. Press the SELECT button 2 times to display the hardness  
setting. Be sure it is the correct setting for the  
household's water supply. (Make a hardness test of the  
raw water and compare with the hardness setting. Also  
test a soft water sample to verify if a problem exists.)  
Press SELECT twice more to return the time of day  
display.  
2. Plumbing bypass valve(s) must be in Full Service  
position.  
3. The inlet and outlet pipes must connect to the softener  
valve inlet and outlet respectively.  
If you do not find the problem after making initial checks,  
do the MANUAL INITIATED ELECTRONIC DIAGNOSTICS,  
and the MANUAL ADVANCE REGENERATION CHECK.  
4. Is the transformer plugged into a live", grounded wall  
outlet, and is the power cable fastened securely?  
5. The valve drain hose must be free of kinks and sharp  
bends, and not elevated over 8 ft. above the floor.

SECTION 5  
5C. WATER FLOW THROUGH THE SOFTENER VALVE  
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 electronic 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, when the valve reaches  
FILL position. As the rotor and disc rotates, the port opens for SOFT water fill  
through the venturi. Fill flowcontinues to the brine valve, and into the salt  
storage tank. Soft water is still available to the house lines.

SECTION 5  
5C. WATER FLOW THROUGH THE SOFTENER VALVE  
BRINING AND BRINE RINSE CYCLES  
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 tankand 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  
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 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 positioned in service until the timer initiates the  
next regeneration.
