A. SAFETY GUIDES
• 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.
• Your water softener will remove hardness minerals
and "clear water" iron* from water, up to the limits
shown on page 4-1. It will not remove other types of
iron, acids, tastes and odors, etc. It will not purify pol-
luted water or make it safe to drink.
• Protect the softener and piping from freezing. Dam-
age from freezing voids the softener warranty. See
page 3-3.

D. SANITIZE THE WATER SOFTENER
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 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 is suggested ®
when installing.
In The first time you sanitize your softener, be sure
in
to do alI steps in the installation manua!, 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.
Lift the salt hole cover and use a pail to fill the
salt storage tank with 3 gallons of water.
Remove the brinewell cover (FIG. 3) and pour
about 3/4 ounce, or I to 2 tablespoons, of com-
mon 5.25%, unscented, household bleach (Clo-
rox, Linco, BoPeep, White Sail, Eagle, etc.) in the
softener brinewell. Replace the brinewell coven

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 full,
and to refill it more often. Salt bridging (see page
3-1) occurs more often when conditions are humid.
Fill 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 brinewell cover is in place
on the top of the brinewell. Salt storage capacity is
shown on page 4-1.
If you choose Potassium Chloride (KC1) as a regen-
erant, following these suggestions will help give
you years of maintenance free service.
1) Place only one bag of KC1 in your softener at a
time (the salt storage tank should contain no more
than 60 pounds of KC1 at any one time).
2) A softener using KC1 should not be placed in
areas with temperature fluctuations and high hu-
midity (KC1 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 KC1 salt setting
you must increase your hardness setting by 25% to
ensure continuous soft water as in example below.

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.

Sodium information: Water softeners using sodium
chloride for regeneration add sodium to the waten
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 will remove or reduce in excess of 90%
of the sodium and other drinking water contami-

• EXTRA RECHARGE
Sometimes, a manually started
regeneration (recharge) may be
desired, or needed. Two exam-
ples are:
- You have used more water than
usual (guests visiting) and you
may run out of soft water before
the next timer started regenera-
tion.
- You did not refill the softener
with salt before it was gone. After
you refill with salt:
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.
Press andrelease (donothold) the ZI: I_ ]i
ON / OFF-HOLD button. RE- -_ IL

the display, and the softener be-
gins regeneration at the next preset recharge time.
Press and release the ON/OFF-HOLD button once
more if you decide to cancel the regeneration, and
RECHARGE TONIGHT.
• 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 pow-
er comes on again, you have to reset the present
time only if the display is flashing. The HARDNESS
and RECHARGE TIME never require resetting un-
less 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, regenera-
tions may occur at the wrong time of day until you
reset the timer to the correct time of day.
• RECHARGE NOW
Press the ON/OFF-HOLD but-
ton and hold for 3 seconds. RE-

B. 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. 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: Salt, dissolved in water, is called brine.
Brine is needed to dean 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. 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.

...... .....I HOW YOUR WATER SOFTENER WORKS
B. 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:
- - 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.
[] 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.

_,_...-:;_;_,: SECTION 2 ;_'_,-_.'_.';._;_1HOW YOUR WATER SOFTENER WORKS
B. SOFT WATER SERVICE and REGENERATION
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 hotwater, 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 []
a WATER METER, and [] a COMPUTER.
[] 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.
[] 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, page 1- 4, you set it for the grains per gallon (gpg)
hardness of the water.
To find a regeneration pattern best for your needs,
the computer uses: (1) water usage from the meter,
(2) hardness setting, (3) softener capacity, and (4)
time since the last regeneration. The computer
always adjusts this pattern to your water using
habits. It works toward providing you with soft
water for the longest time and at the most efficient
salt usage.
Softening capacity is used as hard water goes
through the softener and hardness minerals are
removed. When the computer determines that only
enough capacity remains to provide soft water up to

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 (see note on page 1-6).
Never let the softener use all the
salt before refilling. Without 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.
PLEASE SEE PAGE 1-6 FOR SALT FILLING DIRECTIONS.
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.
If the storage tankis full of salt, it is hard to tellifyou
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 _*
pencil
mark
Salt should be loose all the way to the bottom of the
tank. Hold a broom handle, or like tool, up to the broomhandle /
softener as shown in FIG. 10. 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.

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-
cium and magnesium) out of the water. Also, it can
control some "clear water" iron. See maximum al-
lowed in the specifications on page 4-1. With clear
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 ill-
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 freeze 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.
_'1 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. _p the brine valve upside down
to drain water.
Drain All Water From Softener
drain wood block
J
[]Looking at FIG. 12, 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.
[Tlp 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 will 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 8R22 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 UPI_ 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., pages 1-3 and 1-4.

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: Slide 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.
Then, turn the rotor (clockwise only) to service posi-
tion. _ghten 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.
SERVICING THE VALVE
Inspect all o-rings, seals and gaskets for wear or de-
fects.
Inspect the bottom surface of the rotor for scratches,
chips or wear.
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.

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.

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.

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.
