Safety Guides
Y 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.
Y Your Kenmore Water Softener will remove hardness minerals from water. This is measured in
grains per gallon (gpg). It will also remove some clear water iron*. This is measured in parts
per million(ppm). See the specifications page for the maximum limits of hardness and iron
removal.
Y A water softener will not improve other water problems such as acidity, tastes and odors, or
iron other than clear water iron. lt will not purify contaminated water, or make unsafe water
safe to drink.
Y Check with your local public works department for plumbing, electric and sanitation codes.
You must follow their guides as you install your softener. Use only LEAD FREE SOLDER
AND FLUX, as required by federal and state codes, when installing soldered copper plumbing.
Y Protect the softener and piping from freezing. Damage from freezing voids the softener warranty. See how to protect from freezing on page 31.
CAUTION: Please read and comply with the following guides to prevent damage to the softener or other property, personal injury, or possible fatal shock.
Y This softener works on 24 volts only. Be sure to use only the transformer included.
Plug it into a nominal 120V, 60 cycle household outlet that is grounded and properly
protected by an overcurrent device such as a circuite breaker or fuse. If transformer is
replaced, use only the authorized service Class II, 24 volt, 10 VA transformer.
Y Unplug the transformer right away if the power cable should become damaged or frayed.
Make repairs, or replace the transformer, before plugging back into the power outlet.
Y Always unplug the softener from electrical power before removing outer valve covers.
Y This system is not intended to be used for treating water that is microbiologically unsafe or of
unknown quality without adequate disinfection before or after the system.
* The capacity to reduce clear water iron is substantiated by WQA test data.
European Directive 2002/96/EC requires all electrical and electronic equipment to
be disposed of according to Waste Electrical and Electronic Equipment (WEEE)
requirements. This directive or similar laws are in place nationally and can vary
from region to region. Please refer to your state and local laws for proper disposal
of this equipment.

Typical Installation
WHERE TO INSTALL THE WATER SOFTENER
Review the following points before you choose a place to put your softener.
1. Place as close as possible but always after, the
pressure tank (well water) or water meter (city
water). See Fig. 3.
2. Place as close as possible to a water drain such as
a floor drain, laundry tub, sump or standpipe. See
Fig. 3.
3. Connect to the house main water pipe BEFORE
THE WATER HEATER. See Fig. 3. Temperature of
water going through the softener must not be
more than 120°F (49°C). Hot water will damage
inner softener parts. To reduce the risk of hot water
backup, piping between the softener and water
heater should be as long of a run as possible.
4. Keep outside faucets on hard water to save soft
water and salt. See Fig. 3.
5. Do not install in a place where the softener could
freeze. Damage caused by freezing voids the warranty by Sears, Roebuck and Co.
6. Put the softener in a place where water damage is
least likely to occur if it develops a leak. Sears or
the manufacturer will not repair or pay for water
damage.
7. A grounded, 120V electrical outlet is needed within
10 feet of the softener. See Fig. 3. This is to plug in
the transformer. The softener has a 10 foot power
cable. Be sure the outlet and transformer are in
an inside place, to protect from wet weather. Use
a continuously “live” outlet, which cannot be accidentally switched off.
8. When installing in an outside location, you must take
the steps necessary to assure the softener, installation plumbing, and wiring, are protected from the
elements, contamination, vandalism, etc.
9. Keep the softener out of direct sunlight. The sun’s
heat can melt plastic parts.

Plan Your Installation
PIPE, FITTINGS, OTHER MATERIALS NEEDED
You must first decide how to run “in” and “out” pipes to
the softener. Look at your house main water pipe at the
point you will connect the softener. Is the pipe soldered
copper, glued plastic, or threaded galvanized or brass?
What is the pipe size? What kind of pipe and fittings is it
easiest for you to work with, and what tools do you have?
Now look at the common plans for “in” and “out” piping
on soldered copper. See Fig. 6. Use it as a guide to plan
what materials you will need. Get all the materials you
will need before you start.
SOLDERED
OUT
1” NPT sweat
adaptor (2)*
Use teflon tape,
pipe joint compound
or both.
ALWAYS install the bypass valve (that is included with
the unit) or a three valve bypass. See Fig. 9 to13.
Bypass valves let you turn off water to the softener if
needed for repairs, but still have water in the house
pipes.
Drain tubing (3/8” inside diameter), is needed for the
valve and salt tank drains. See Fig. 16. If a rigid valve
drain is needed to comply with plumbing codes, you can
buy the parts needed (see Fig. 16) to change the softener to a 1/2 inch minimum copper tubing drain.

Use Fig. 5 to make a plan drawing for your specific
installation. “In” and “out” fittings included with the softener are 1” NPT threaded adaptors. You should maintain
the same, or larger, pipe size as the water supply pipe,
up to the softener inlet and outlet. Use copper, brass,
galvanized or PVC plastic pipe and fittings for the “in”
and “out” pipes. Be sure to check local codes.
Note: If converting from galvanized to copper pipe
use approved dielectric insulating connectors.

Read Before Beginning Installation
BEFORE INSTALLING CHECKS & TESTS
Your water supply needs to be checked for chemical
analysis, water pressure and water flow rate. To accomplish this, complete the following steps:
Check Water’s Chemical Analysis: Sears sells a complete line of water treating equipment to correct various
water problems. To be sure you have the proper type
and size equipment, You must have your water tested.
Your Sears store can give you a water test results for
hardness, iron and acidity, and tell you what equipment
you need. Simply take at least a 4 oz. sample of your
water to Sears, and they will test it while you wait. If you
need help to get your water tested, or if you have other
questions about your water, ask at your Sears store.
NOTE: Add these readings to the Facts and Figure
table on page 3.
Check Your Water Pressure: For your softener to work
right, a water pressure of no lower than 20 pounds per
square inch (psi) is needed in the house water pipes.
The highest pressure allowed in the water pipes is 125
psi. If pressure is over 125 psi, buy and install a pressure reducing valve in the water inlet pipe to the softener.
NOTE: If water pressure during the day is 100 psi or
more, pressure during the night may go over 125 psi.
Adding a pressure reducing valve may reduce the
flow.
NOTE: Add these readings to the Facts and Figure
table on page 3.
If you have a well water system, look at the pressure
gauge to find the water pressure. Call your local water
department if you have city water. They will tell you what
the water pressure is where you live.
NOTE: Add these readings to the Facts and Figure
table on page 3.
Check your water flow rate: A water flow of at least 3
gallons per minute is needed. A lower flow will keep your
softener from working as well as it should. Complete the
following steps to make an easy check of your flow rate.
1. Fully open two cold water faucets close to the point
water enters the house.
2. With both faucets open, fill a gallon container at one
faucet while looking at a watch or clock to see how
many seconds it takes.
3. Empty the container and go to the second faucet (be
sure BOTH faucets are still on). Fill the gallon container
at the second faucet and see how many seconds it
takes.
4. Turn off both faucets. Now add the number of seconds
it took to fill the container at both faucets.
5. A total of 90 seconds, or less, means the system flow
rate is good.
NOTE: Add these readings to the Facts and Figure
table on page 3.
NOTE: Codes in the state of Massachusetts require
installation by a licensed plumber. For installation,
use plumbing code 248CMR of the Commonwealth
of Massachusetts.

Locate Water Softener and Connect Pipes
POSITION SOFTENER INTO PLACE
Complete the following steps to position the softener.
1. Grip under the ridge on the salt tank sidewall.
2. Carefully rock back and forth into position.
3. Move the softener into position.
4. Place on a level and smooth surface. If needed, put a
piece of 3/4” plywood, at least 17'' x 20'', under the
tank. Then put spacers under the plywood to level the
softener. See Fig. 14.
MOVE SOFTENER INTO PLACE
Grip under ridge
to move softener.
NOTE: Do not put shims or spacers directly under
the tank, without the plywood. The weight of the softener, when full of salt and water, may cause the tank
to puncture or break at the shim or spacer.
CONNECT THE SOFTENER
Refer to your plan drawing. See Fig. 5.
Measure, cut (thread if needed) and put all pipe and fittings together up to the main water pipe, or to the
bypass valve(s) you installed in the previous step.
CAUTION: Never solder fittings while connected to
nonmetallic parts. Wait until soldered pipe has
cooled before connection. See Fig. 15.
CAUTION: Be careful when putting pipe fittings
together. Do not cross thread, and do not overtighten.

Connect Valve and Salt Tank Drains
CONNECT THE VALVE DRAIN HOSE
Take a length of 3/8” inside diameter drain tubing and
attach one end to the drain fitting. See Fig. 16. Use a
tube clamp to hold it in place. Put the other end of the
tubing over a floor drain, into a laundry tub, standpipe,
or other suitable drain. Check your local codes.
Leave an air gap of about 1-1/ 2'' between the end of
the hose and the drain. This gap is needed so you
don’t get a backflow of sewer water into the softener.
Do not put the end of the hose into the drain or connect without the air gap.
Place and support the hose so it does not kink or have
sharp bends. Secure the hose end so water pressure
does not cause the hose to “whip”. Tie or wire it in
place. Do not pinch the hose shut. The softener will
not work if this drain hose is pinched, plugged,
closed or restricted in any way. Direct drain flow
down into drain from drain line as flow could possibly
over shoot the drain cover.
Keep the hose lower than the drain fitting. In some
homes, to get to a drain you must raise the hose and
run it overhead. If you need an overhead drain, do not
raise the hose more than 8' above the floor. A copper
drain tube is best to use.
COPPER DRAIN TUBE: Local plumbing codes may
require the use a copper valve drain tube. A copper
tube is also best to use for an overhead drain. Use a
copper drain tube if the softener is installed outside, or
in the sunlight. Heat from the sun can soften, flatten
and close up some kinds of tubes.
To adapt a copper drain tube to the softener, buy a
compression fitting (1/4'' female pipe threads x 1/2''
O.D. tube) and tubing from your local hardware store.
CONNECT SALT TANK OVERFLOW TUBING
1. Locate the rubber grommet, tube adaptor and tube
clamp (see Fig. 16) that are in the parts bag.
2. Push the grommet into the hole in the salt tank wall
so half is inside and half is outside.
3. Push the bigger end of the tube adaptor into the
grommet.
4. Push one end of a length of 3/8'' I.D. tubing onto the
tube adaptor, using the tube clamp to hold it in
place.
5. Put the other end of the tubing over the floor drain.
IMPORTANT: Overflow water must run downward
through the tubing. Do not raise the tubing higher
than the grommet and tube adaptor. See Fig. 16.
IMPORTANT: Do not connect to the valve drain
hose you installed in step 1. Both drains must
have a separate hose or tube.

2. Look at the pictures in Fig. 18 and 19 to determine your kind of bypass valve(s). Place bypass
valve(s) in “bypass” position. On a single valve,
slide the stem inward to bypass. On a three (3)
valve system, close the inlet and outlet valves and
open the bypass valve.
3. Fully open the house main water pipe shutoff
valve. Observe steady water flow from both open
faucets.
4. Place bypass valve(s) in SERVICE EXACTLY as
follows: Keep soft water faucets open.
a. Single Bypass Valve: Slowly, slide pull the
valve stem outward toward service, pausing several times to allow the softener to pressurize slowly.
b. Three Valve Bypass: Fully close the bypass
valve and open the outlet valve. Slowly, open the
inlet valve, pausing several times to allow the softener to pressurize slowly.
5. After about three minutes, open a hot water
faucet for about one minute, or until all air is
expelled, then close.
6. Close both cold water faucets.
7. Check your plumbing work for leaks and fix right
away if any are found. Be sure to observe previous caution notes.
NOTE: If this procedure is performed on a new
softener, water coming from the taps may initially be discolored. This normally occurs the first
time water runs through the resin bed. The discolored water is not harmful, and the discoloration will not last more than a few minutes.

COLD WATER PIPE GROUNDING
The house cold water pipe (iron or copper) is often
used to ground all electrical outlets in the home.
Outlets are grounded to protect you from shock when
you touch any electric appliance plugged into the outlet. If you installed the single bypass valve, the cold
water pipe ground is broken. See Fig. 20 and 21.

Also check the water meter (city water) or the well
pump. Install #4 copper jumper wires, clamped
tightly on both ends, across insulated parts. See
Fig. 21.
To restore the ground, take the ground clamp kit that is
in the parts bag. Install across the inlet and outlet copper tubes. See Fig. 20. Be sure good contact is made

To set the water hardness number, complete the following steps:
1. Press the SELECT button once to display the words
SET HARDNESS and a flashing 25. The grains per
gallon (gpg) hardness of your water supply is on your
water analysis report. Be sure to enter water test
results on the Facts & Figure Chart on page 3.
2. If your water supply contains iron, compensate for it
by adding to the water hardness number. For example, assume your water is 20 gpg hard and contains
2 ppm iron. Add 5 to the hardness number for each I
ppm of iron. In this example, you would use 30 for
your hardness number.
2 ppm iron x 5 = 10
20 gpg hardness

To set the salt level, complete the following steps:
1. Press the SELECT button to display SET SALT
LEVEL and a flashing 0 (zero). See page 21, for
instructions on adding salt to the salt storage tank.
The face plate timer has a salt monitor with an indicator light to remind you to add salt to the storage
tank.
NOTE:You must set salt level each time salt is
added to the water softener.
2. To set this monitor system, lift the salt hole cover
and level the salt in the storage tank. The salt level
decal, on the brinewell inside the tank, has numbers
from 0 to 8. Observe the highest number the leveled
salt is at, or closest to. Press the UP or DOWN buttons until the number corresponds with the salt level
number. At level 2 or below, the indicator LED will
flash. If you wish to turn this feature off, press the
DOWN button past 0, and the word “OFF” flashes in

show in the display.
3. Press the UP or DOWN buttons to set your water
hardness number in the display. The DOWN button
moves the display to 1. The UP button moves the
display to the highest setting (see maximum setting
for your model in the specifications).
NOTE: Each press of the UP or DOWN button
changes the display by 1 between 1 and 25.
Between 25 and the highest number, the display
changes 5 at a time (25, 30, 35, etc.) Holding the

To complete setting the regeneration time, complete the
following steps:
1. Press the SELECT button to display the words SET
RECHARGE TIME and a flashing 2:00 AM.
2. At the 2:00 AM recharge time setting, the softener
begins regeneration (see pages 25 - 27) at 2:00 AM.
This is a good time in most households because
water is not being used. If a different recharge time
setting would be better for your household, complete
the following step.
3. Press the UP or DOWN buttons to set the desired
recharge starting hour. Be sure to observe the AMPM as you did when setting the present time of day.
Note: Each press of the UP or DOWN buttons

Sanitize The Water Softener
SANITIZE 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, or cause bacteria to
form or grow. However, during shipping, storage, installing
and operating, bacteria could get into the softener.
SANITIZE YOUR WATER SOFTENER AS FOLLOWS:
1. Be certain the bypass valve is pulled out to
“service” position.
2. Lift the salt hole cover and using a pail add up to 3 gallons
of water to the salt storage tank.
3. Remove the brine well cover (Fig. 28) and pour about 3/4
ounce, or 1 to 2 tablespoons, of common 5.25%1, unscented, household bleach (Clorox, Linco, BoPeep, White Sail,
Eagle, etc.) in the softener brinewell. Replace the brinewell
cover.
4. Press the REGENERATION button and hold for 3 seconds
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 25) for service and
flushes residual chlorine from the softener.

NOTE: This recharge takes about 2-1/2 to 2-3/4 hours,
depending on the salt type setting.
NOTE: During a recharge the water softener bypasses
raw water to the home. You will not get salty water or
affect the regeneration cycle if water is used at this time.
You can sanitize the softener with or without salt in the
storage tank.

Recommended by the Water Quality Association.
On some water supplies, the water softener may need periodic disinfecting.
Your new Sears softener is now softening the water for your
household needs. However, your WATER HEATER is filled
with hard water. To have fully soft water right away, you can
drain the water heater so it refills with soft water. If you don’t
drain the water heater, it will take a few days before you have
fully soft water.
To drain the water heater, open a hot water faucet and let it
run until the water runs cold. Then close the faucet.
NOTE: If this procedure is performed on a new softener,
water coming from the taps may initially be discolored.
This normally occurs the first time water runs through
the resin bed. The discolored water is not harmful, and
the discoloration will not last more than a few minutes.

FIG. 28
Adding Salt To The Storage Tank
ADDING 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 water 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 add salt more
often. Salt bridging occurs more often when conditions
are humid.
Brinewell
Cover
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.To maintain optimum performance of your water softener, the salt tank should be
cleaned out every 2 to 3 years.
Before adding salt, be sure the brinewell cover is in place
on the top of the brinewell. It is recommended to set the
salt monitor system, although it is not required for proper
operation.
NOTE: The salt monitor system 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 rock and solar.

Tank
If you choose Potassium Chloride (KCI) as a regenerant,
following these suggestions will help give you years of
maintenance free service.
FIG.29
1. Place only one bag of KCI in your softener at a time
(the salt storage tank should contain no more than
60 pounds of KCI at any one time).
2. A softener using KCI should not be placed in areas
with temperature fluctuations and high humidity (KCI
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. If your softener does not have a KCI salt setting you
must increase your hardness setting by 25% to ensure
continuous soft water as in example below.

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 sodium. That is
equivalent to eating 2-1/2 slices of white bread.
WATER SOFTENING SALT WITH IRON
REMOVING 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 (refer to the
Parts List in back of manual for part number) for periodic treatments to keep your resin bed clean. This is available at your local Sears store.
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.

EXTRA RECHARGE
Sometimes, a manually started regeneration (recharge)
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. Add salt to the softener before regenerating.
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).
RECHARGE NOW
Press the REGENERATION button and hold for 3 seconds. The words RECHARGE NOW begin to flash in the

Faceplate Timer Features
California Efficiency Requirement
Your Kenmore Water Softener has a “High Efficiency”
feature with an “ON” or “OFF” setting. This softener
setting is shipped in the “OFF” position, which utilizes
the maximum rated capacity 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.
EFFICIENCY MODE
When this feature is ON, the water softener will operate
at salt efficiencies of 4000 grains of hardness per pound
of salt or higher. (May recharge more often using smaller
salt dosage and less water). Installations in the state of
California require this setting to be turned ON. This
softener is shipped in the OFF setting.
To turn this setting ON:
1. Press and hold the SELECT button until the display
shows 000--.
FIG. 34
2. Then press (do not hold) the SELECT button again.
Use the UP arrow to turn ON.
3. Press SELECT to enter and return to normal running
screen. The efficiency icon will only be displayed when
this feature is ON.
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, RECHARGE TIME
and SALT 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.
ERROR CODE
An error code could appear in the face plate display if a
problem occurs in the softener electronics. Turn to the

How Your Water Softener Works
SOFT WATER SERVICE AND REGENERATION
SERVICE
When the softener is giving you soft water, it is called
“Service”. See Fig. 36. 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. As hard water
passes through the bed, each bead attracts 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 minerals they can, and cleaning with salt
brine is needed. This cleaning is called regeneration or
recharge. Regeneration is started at 2:00 a.m. by the
electronic timer. It takes place in 5 stages or cycles.

The five steps listed above are described in detail over
the next several pages.
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. See Fig. 37. 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.

How Your Water Softener Works
SOFT WATER SERVICE AND REGENERATION
BRINING: During brining, the brine is moved from the
salt storage area, into the resin tank. See Fig. 38.
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 water used between regenerations.
• The amount of resin in the softener,
• How fast the brine goes through the bed.
The nozzle and venturi makes 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 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. See Fig. 38.
BACKWASH: During backwash, water flows UP
through the resin tank at a fast rate to flush iron minerals, dirt and sediments from the bed and to the drain.
The bed lifts and expands for good cleaning. See Fig.
39.

How Your Water Softener Works
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.
See Fig. 40.
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.

SOFT WATER SERVICE AND REGENERATION
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 4:20 AM, a
time when not much water is used.
FIG. 40
If you start your day prior to 4 AM, you may need to
change the recharge starting time. Set the recharge time
to 12:00 AM or 1:00 AM. 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.
• 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.
• 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, 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
(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.

Care Of Your Water Softener
SALT BRIDGE
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.
SALT BRIDGE
Push tool into
salt bridge to break
1” - 2”
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. 41. 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.

Care Of Your Water Softener
KEEPING THE WATER SOFTENER CLEAN
NOZZLE & VENTURI
A clean nozzle and venturi (see Fig. 42) 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 clean the nozzle and venturi, complete the following
steps:
1. Remove the softener top cover. Be sure the softener
is in service cycle (no water pressure at nozzle and
venturi).
2. Turn off the cap from the nozzle and venturi housing.
3. Lift out the screen support and screen. Do not lose
the large o-ring seal.
4. Remove 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.
5. Carefully replace all parts in the correct order.
6. Lubricate the o-ring seal with silicone grease or
Vaseline and place in position.

FIG. 42
IRON FROM RESIN BED
Your water softener takes hardness minerals (calcium
and magnesium) out of the water. It can also control
some “clear water” iron. See maximum allowed in the
specifications section in this manual. 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 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. Your local Sears store has resin
bed cleaner for this. See Parts List in back of manual
for part numbers. Clean the bed at least every six (6)
months. If iron shows up in the soft water before six (6)
months, clean more often. Printed instructions are on
the resin bed cleaner bottle.

Care Of Your Water Softener
PROTECT THE WATER SOFTENER FROM
FREEZING
DRAIN ALL WATER FROM SOFTENER
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. 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.
Floor Drain
Wood Block
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. Separate the softener from the
plastic installation adaptors, or from the bypass
valve.
6. Remove the brinewell cover and disconnect the brine
valve tubing at the nozzle and venturi assembly. Lift
the brine valve out of the brinewell. Tip the brine
valve upside down to drain water.
7. 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.

CHECKLIST TO HELP YOU SAVE MONEY
If your water softener fails to work, make the following easy checks. Often, you will find what is 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.
1. Also read ERROR CODE.
2. If an error code is not displayed, press and hold the SELECT button until the display changes. Then, press the
SELECT button again and hold until a flashing code appears. It must show S 25 for Model 38306, or S 26 for
Model 39306. 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 S 25 or S 26, press either the UP or DOWN button. When the correct
model code shows, press SELECT to return a flashing 12:00 AM display. Reset the present time, hardness number, etc.
PROBLEM

and correct. With the power back on, look at
the time display and read PROGRAM MEMORY, see page 24.
Manual bypass valve(s) in bypass position
Look at Fig. 18 & 19 on page 15. Move the
stem in a single valve to service. In a 3-valve
bypass, open the inlet and outlet valve, and be
sure to fully close the bypass valve.
Dirty, plugged or damaged nozzle venturi
Take apart and clean or replace damaged
parts, see page 29.

Service Tech Information
The faceplate timer (PWA) computer has a self-diagnostic function for the electrical system, except put
power and water meter. The computer monitors electronic components and circuits for correct operation. If a
malfunction occurs, an error code appears in the faceplate display.
FIG. 47
The chart below shows the error codes that could
appear, and the possible defects for each code.
POSSIBLE DEFECT

Err5
faceplate timer (PWA)
While an error code appears in the display, all face
plate buttons are inoperable except the SELECT button.
SELECT remains operational so the service person can
make the MANUAL INITIATED ELECTRONIC DIAGNOSTICS (below) to further isolate the defect, and
check the water meter.
PROCEDURE FOR REMOVING ERROR CODE
FROM FACEPLATE:
FIG. 48
• Unplug transformer from outlet.
• Correct defect
• Plug in transformer.
• Wait for 8 minutes.
The error code will return if the defect was not corrected.
MANUAL INITIATED ELECTRONICS DIAGNOSTICS:
To enter diagnostics, press the SELECT button until
000 - - shows in the display. See Fig. 48.
TURBINE OPERATION: If no water is flowing through
the softener, the turbine indicator displays three zeros.
When water is flowing, the flow bar scrolls across the
display, and a 000 to 199 count repeats for each gallon
of water passing through the turbine. To check for positive operation of the turbine if zeros are shown, open a
nearby soft water faucet and observe the turbine count
and flow bar. If you don’t get a reading in the display,
with faucet open, pull the sensor from the valve outlet
port. Pass a small magnet back and forth in front of the
sensor. You should get a reading in the display. If you
get a reading, unhook the in and out plumbing and
check the turbine for binding.
POSITION SWITCH STATUS: With the valve in service,
or any of the recharge cycles, the switch indicator will
show open, while the valve is rotating from one position
to another, the indicator will show the switch closed. A
defect is probable if indications vary from this pattern.

NOTE: Be sure a salt bridge is not preventing
water with salt contact.
5. If the softener does not draw brine:
• nozzle and/or venturi dirty or defective
• nozzle and venturi not seated properly on gasket
• restricted drain (check drain fitting and hose)
• defective nozzle and venturi seal
• other inner valve defect (rotor seal, rotor & disc,
wave washer, etc.)
NOTE: If water system pressure is low, an elevated
drain hose may cause back pressure, stopping
brine draw.
6. Again press REGENERATION to move the softener
into backwash. Look for a fast flow of water from the
drain hose.
7. An obstructed flow indicates a plugged top distributor,
backwash flow plug or drain hose.
8. Press REGENERATION to move the softener into fast
rinse. Again look for a fast drain flow. Allow the softener to rinse for a few minutes to flush out any brine that
may remain in the resin tank from the brining cycle
