U J J J J J JJ J'JJ
JJJJJJ JJJ J.J.J ' ' '
1 WATER SOFTENER START UP
Care is taken at the factory to keep your water soft
ener clean and sanitary. Materials used to make the
softener will not infect or contaminate your water
supply, and win not cause bacteria to form or grow.
However, during shipping, storage, installing and
operating, bacteria could get into the softener. For
this reason, sanitizing as follows is suggested®
when installing.
The first time you sanitize your softener, be sure
to do all steps in the installation manual, and on
pages 1-2,1-3 and 1-4 of this manual first.
Note: Be certain the bypass valve is pulled out
to "service" position.
0 Lift the salt hole cover and use a paU to fill the
salt storage tank with 3 gallons of water.
Remove the brineweU cover (FIG. 3) and pour
about 3/4 ounce, or 1 to 2 tablespoons, of com
mon 5.25%, unscented, household bleach (Clorox, Linco, BoPeep, White Sail, Eagle, etc.) in the
softener brineweU. Replace the brineweU cover.
^2 Press the ON/OFF-HOLD button and hold for 3
seconds to start a recharge. This first recharge
does several things.
FIG.3
• It draws the bleach into and through the softener
to sanitize it.
• It fills the salt tank to the water level needed.
• It gets all the air out of the resin tank.
• It prepares the resin bed (see page 2-3) for ser
vice and flushes residual chlorine from the soften
er.
Notes:
This recharge takes about 2 hours.
You can sanitize the softener luith or without salt
in the storage tank.
Recommended by the Water Quality Association. On some
water supplies, the water softener nuy need periodic
disinfecting.

E. 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 salt in the tank, but it is not
necessary to keep it full. In humid areas, it is best
to fill the storage tank one quarter to one half fuU,
and to refill it more often. Salt bridging (see page
3-1) occurs more often when conditions are humid.
Fül the tank with NUGGET or PELLET water soft
ener salt. DO NOT use rock salts, as they have dirt
and sediments that will stop the softener from
working.
Before filling, be sure the brineweU cover is in place
on the top of the brinewell. Salt storage capacity is
shown on page 4-1.
If you choose Potassium Chloride (KCl) as a regen
erant, following these suggestions will help give
you years of maintenance free service.
1) Place only one bag of KCl in your softener at a
time (the salt storage tank should contain no more
than 60 pounds of KCl at any one time).
2) A softener using KCl should not be placed in
areas with temperature fluctuations and high hu
midity (KCl 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 KCl salt setting
you must increase your hardness setting by 25% to
ensure continuous soft water as in example below.

WATER SOFTENING SALT WITH IRON REMOV
ING ADDITIVES — Some salts have an additive to
help the softener handle iron in the water supply.
These salts may be used if your water supply has a
high iron content. It is recommended to use Sears
Resin Bed Cleaner 42- 34426, for periodic treatments
to keep your resin bed clean. This is available at
your local Sears store.
FIG. 4
salt
storage
tank
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 so
dium. That is equivalent to eating 2-1/2 slices of
white bread.
Persons who are concerned about their drinking
water should consider a Kenmore Drinking Water
System that wiU remove or reduce in excess of 90%
of the sodium and other drinking water contami
nants.

B. SOFT WATER SERVICE and REGENERATION
4vI444J44J4JJJJ4
JJ4
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. 5). As
hard water passes through the bed, each bead at
tracts and holds the hardness minerals. This is
called ion-exchanging. Water without the hardness
minerals (soft water) flows out of the softener and
into the house soft water pipes.After a period of
time, the resin beads hold all of the hardness miner
als they can, and cleaning with salt brine is needed.
This cleaning is called regeneration or recharge. Re
generation is started at 2:00 a.m. by the electronic
timer (see page 2-5). It takes place in 5 stages or
cycles. These are:
FILL
BRINING
BACKWASH
FAST RINSE
BRINE RINSE
REGENERATION
D FILL: Salt, dissolved in water, is called brine.
Brine is needed to clean the hardness minerals from
the resin beads. To make the brine, water flows into
the salt storage area during the fill stage as shown
in FIG. 6. Fin 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
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 service water used between regen
erations,
- - the amount of resin in the softener,
- - how fast the brine goes through the bed.
The nozzle and venturi {FIG. 7) make suction to take
brine from the salt tank and put it into the resin tank.
They keep the brine flow down to a very slow rate
to get the best resin cleaning with the least salt.
13 BRINE RINSE: After all of the brine is moved
into the resin tank, the brine valve closes. Water
keeps flowing the same way it did during brining
except the brine flow has stopped. Hardness miner
als and brine flush from the resin tank to the drain.
Brining and brine rinse together vary in the length
of time they take, relative to the fill cycle length.

FAST RINSE: Backwash is followed by a fast
flow of water down through the resin tank. The fast
flow packs the resin bed and gets it ready for return
to service (FIG. 9).
After fast rinse, the softener returns to service. Hard
water goes into the resin tank where the resin bed
again takes out the hardness minerals. Soft water
goes to the house soft water pipes.

HOW YOUR WATER SOFTENER WORKS
AUTOMATIC BYPASS
During the brining, brine rinse and backwash cycles
of regeneration, HARD water goes through the soft
ener valve and to the house pipes. If a faucet is
opened, hard water is there for your needs. Howev
er, you should not use hot water, if possible, because
the water heater will refill with hard water. The soft
ener, as factory programmed, regenerates from 2:00
AM to about 4:00 AM, a time when not much water
is used.
If you start your day earlier in the morning (prior ro
4:00 AM), you may want to change the recharge
starting time. Set the recharge time to 12:00 AM or
1:00 AM (page 1-4). Then regeneration will start
and end that much earlier and your water heater
will not refill with hard water if a hot faucet is
opened.
ELECTRONICS
Two main parts of the softener's electronics are Q]
a WATER METER, and [2] a COMPUTER.
Q] WATER METER—The water meter is in the soft
ener valve outlet. As water flows through the meter,
it sends electric pulses to the computer. The com
puter changes the pulses to a measure in gallons of
water.
El COMPUTER — The computer is part of the
faceplate timer circuit board. It is programmed to
know the softener's capacity (how many grains of
hardness minerals it will take out of the water before
a regeneration is needed). When starting the soften
er, pagel-4, youset it for the grains per gallon (gp g)
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 wiU schedule a regeneration.
RECHARGE TONIGHT displays until the
regeneration begins. When the regeneration begins,
RECHARGE TONIGHT goes off and RECHARGE
NOW flashes during the regeneration.

SALT BRIDGE
Sometimes, a hard crust or salt bridge forms in the
salt storage tank. It is usually caused by high hu
midity or the wrong kind of salt. When the salt
bridges, an empty space forms between the water
and salt. Then salt will not dissolve (melt) in the wa
ter to make brine. Without brine, the resin bed does
not regenerate and you will have hard water.
salt before refilling. lA^thout salt, you will soon have
hard water.
Note:
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.
FIG. 10
Salt Bridge
If the storage tank is fuU of salt, it is hard to teU 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 aU the way to the bottom of the
tank. Hold a broom handle, or like tool, up to the
softener as shown in FIG. 10. Make a pencil markon
the handle, 1" or
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.
If the wrong kind of salt made the bridge, take it out.
Then fill the tank with nugget or pellet salt only.

B. KEEPING THE WATER SOFTENER CLEAN
NOZZLE & VENTURI
A clean nozzle and venturi (FIG. 11) is a must for the
softener to work right. This small unit moves brine
from the salt storage tank to the resin tank during re
generation. If it becomes plugged with sand, silt,
dirt, etc., the softener will not work and you will get
hard water.
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).
1) Turn off the cap from the nozzle and venturi hous
ing.
2) Lift out the screen support and screen, do not lose
the large o-ring seal
3) Then the nozzle and venturi. Wash and rinse the
parts in warm water until clean. If needed, use a
small brush to remove iron or dirt. Also check and
clean the gasket, flow plugs and screens.
Carefully replace all parts in the correct order. Lu
bricate the o-ring seal with silicone grease or Vase
line and place in position. Install and tighten the
cap, by hand only. Do not overtighten and break
the cap or housing.

IRON FROM RESIN BED
Your water softener takes hardness minerals (cal

control some "clear water" iron. See maximum al

water iron, water from a faucet is clear when first
put into a glass. After 15 to 30 minutes, the water be
gins 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 fil

ter or other equipment is needed. Your local Sears
store has trained people to help you with iron water
problems.
If your water supply has clear water iron, even
though less than the maximum allowed, regular
resin bed cleaning is needed. Your local Sears store
has resin bed cleaner. Item No. 42-34426 for this.
Clean the bed at least every 6 months. If iron shows
up in the soft water before 6 months, clean more
often. Printed instructions are on the resin bed
cleaner bottle.

C. PROTECT THE WATER SOFTENER FROM FREEZING
If the softener is installed where it could freeze
(summer cabin, lake home, etc.), you must drain all
water from it to stop possible feeze damage. To
drain the softener:
Close the shut-off valve on the house main wa
ter pipe, near the water meter or pressure tank.
Open a faucet in the soft water pipes to vent
pressure in the softener.
Refer to FIG. 14 on page 4-1. Move the stem in
a single bypass valve to bypass. Close the inlet
and outlet valve in a 3-valve bypass system, and
open the bypass valve. If you want water in the
house pipes again, reopen the shut-off valve on
the main water pipe.
Unplug the transformer at the wall outlet. Re
move the salt hole cover and the main cover.
Take off both drain hoses.
Carefully remove the large holding clips at the
softener inlet and outlet (see Key No. 66, on page
6-3). Separate the softener from the copper
tubes, or from the bypass valve.
Remove the brinewell cover and disconnect the
brine valve tubing at the nozzle and venturi as
sembly (see page 3- 2). Lift the brine valve out of
the brinewell. Tip the brine valve upside down
to drain water.
FIG. 12
Drain All Water From Softener
Looking at FIG. 12, lay a piece of 2 inch thick
board near the floor drain. Move the softener
dose to the drain. SLOWLY and CAREFULLY,
tip it over untd 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.
Tip the bottom of the softener up a few inches
and hold until all water has drained. Leave the
softener laying like this until you are ready to
use it. Plug the inlet and outlet with rags to keep
dirt, bugs, etc. out.

D. CHECKLIST ... TO HELP YOU SAVE MONEY
If your water softener fails to work, make the following easy checks. Often, you wül find what's wrong your
self and you won't have to call and wait for service. If you do not find anything wrong, while making the
checks, and your softener still does not work, call Kenmore Water Line at 1-800-426-9345.
Note:
1. Also read ERROR CODE, page 2-1.
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 SR code appears. It must show SR22 for UltraSoft 100 or
SR24 for UltraSoft 150. 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 SR22 or SR24, press either the UF17^ or DOWN(vl button.
When the correct model code shows, press SELECT to return a flashing 12:00 AM display. Reset the present
time, hardness number, etc., pages 1-3 and 1-4.

A. TROUBLESHOOTING
MANUAL ADVANCE REGENERATION CHECK
This check verifies proper operation of the valve
motor, brine tank fill, brine draw, regeneration flow
rates, and other controller functions. Always make
the initial checks, and the manual initiated drag-
nostics.
Notes:
The faceplate display must show a steady time (not
flashing). If an error code shows, first press the SE
LECT button to enter the diagnostic display.
Press the ON / OFF-HOLD button and hold in for
3 seconds. RECHARGE begins to flash as the
softener enters the fill cycle of regeneration. Re
move the brinewell cover and, using a flashlight,
observe fill water entering the tank.
a. If water does not enter the tank, look for an ob
structed nozzle, venturi, fill flow plug, brine tubing,
or brine valve riser pipe.

Again press ON/OFF-HOLD to move the soft
ener into backwash. Look for a fast flow of water
from the drain hose.
a. An obstructed flow indicates a plugged top dis
tributor, backwash flow plug, or drain hose.
Press ON/ OFF-HOLD 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 test.
To return the softener to service, press ON / OFF
HOLD.
After observing fill, press the ON / OFF-HOLD
button to move the softener into brining. A slow
flow of water to the drain will begin. Verify brine
draw from the brine tank by shining a flashlight
into the brinewell and observing a noticeable
drop in the liquid level.
Note:
Be sure a salt bridge is not preventing water with
salt contact.
a. 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.

B. ROTARY VALVE SERVICE
Before working on the valve, turn off the water sup
ply and disconnect from electrical power. TO RE
LIEVE 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: Shde the bypass valve
stem to bypass position. Loosen 3 hex head screws
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 disassemble.
SERVICING THE VALVE
Inspect aU o-rings, seals and gaskets for wear or de
fects.
Inspect the bottom surface of the rotor for scratches,
chips or wear.
Then, turn the rotor (clockwise orJy) to service posi
tion. lighten the screws using a criss-cross pattern.
If a torque wrench is available, torque to 30-40 inch
pounds.
Lubricate the gear on the motor, and the valve cam
gear with Molykote grease, or other high quality
gear lubricant.
Be sure to orient switch as shown, with lever toward
the cam.

switc:
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 posi
tion. Lubricate ALL o-rings and seals with FDA ap
proved 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, care
fully center the wear strip on the seal, and push it
downward onto the seal.
Install the nozzle and venturi seal and drain seal.
Assemble wave washer bearing, the wave washer,
and two o-rings onto the rotor top shaft. Then center
the rotor in the valve body, on the rotor seal.
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.

SERVICE TECH. INFORMATION
C. 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 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.

water
to valve outlet
\ drain
from Valve Inlet
(hard water)
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 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.

C. WATER FLOW THROUGH THE SOFTENER VALVE
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.
