WATER SOFTENER START-UP
SECTION 1
1D.
SANITIZING THE WATER SOFTENER
Care is taken at the factory to keep your water
softener clean and sanitary. Materials used to make
the softener will not infect or contaminate your water
supply, and will not cause bacteria to form or grow.
However, during shipping, storage, installing and
operating, bacteria could get into the softener. For
this reason, sanitizing as follows is suggested¬ when
installing.
FIG. 2 ADD WATER

1. The first time you sanitize your softener, be sure
to do all steps in the installation manual, and on
pages 5, 6 and 7 of this manual first.

about 3/4 oz. bleach)
2. Lift the salt hole cover and use a pail or hose to fill

water.

3. Remove the brinewell cover (FIG. 3) and pour
about 3/ 4 ounce of common 5.25% household

etc.) in the softener brinewell.
water,
about 3 gallons
4. Press the ON/OFF-HOLD button and hold for 3
seconds to start a recharge. This first recharge does
several things.
— It draws the bleach into and through the soft-
ener 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 13) for ser-
vice.
NOTES:
This recharge takes about 2-1/ 2 or 2-3/ 4 hours,
depending on the salt type setting (page 7).
You can sanitize the softener with or with-
out salt in the storage tank.
¬
Recommended by the Water Quality Association. On
some water supplies, the water softener may need pe-
riodic disinfecting.

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 20. Be sure to set the salt monitor
system (see page 10).
POTASSIUM CHLORIDE, alternate to salt: The
design of this softener allows for the use of potas-
sium chloride in place of salt (sodium chloride).
Potassium chloride does not add sodium to the
water, and is more ecologically friendly. Disadvan-
tages include higher cost, irregular dissolving fac-
tors, and the need for longer softener regeneration
times. If you do use potassium chloride, see page 7 to
set the timer for its use.

NOTES:
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.
The salt monitor system, page 10, 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 potassium chloride, rock and solar.
In humid areas, it is best to fill the storage tank
half-full, and to refill it more often. Salt bridging (see
page 16) occurs more often when conditions are
humid.
For example, if your water supply is 15 grains hard,
you would have to drink 3 quarts of softened water
to consume 335 milligrams of sodium. That is
equivalent to eating 2-1/ 2 slices of white bread.
WATER SOFTENING SALT WITH IRON REMOV-
ING ADDITIVES — Some salts have an additive to
help the softener handle iron in the water supply.
Although this additive may help to keep the softener
resin clean, it may also release corrosive fumes that
will weaken and shorten the life of some softener
parts.
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.
The design of this softener also allows the use of potassium
chloride as an alternate to salt (see above, left). Potassium
chloride does not add sodium to the water.
You have now finished the water softener start up. After the sanitizing recharge, on
page 8, the softener will be giving you soft water.

FACEPLATE TIMER FEATURES
EXTRA RECHARGE
SALT MONITOR SYSTEM
Sometimes, a manually started regeneration (re-
charge) may be desired, or needed. Two examples
are:
The faceplate timer has a low salt monitor with an
indicator light to remind you to refill the storage tank
with salt. To set this monitor system:
- -You have used more water than usual (guests
visiting) and you may run out of soft water before the
next timer started regeneration.
1. Lift the salt hole cover and level the salt in the
storage tank (press tank light button to light inside
of tank).
- -You did not refill the softener with salt before it was
gone.
2. The salt level decal, on the brinewell inside the
tank, has numbers from 0 to 8 (see drawing on
page 9 and below). Observe the number the
leveled salt is at or closest to.
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.
3. Now, press the SALT LEVEL ADJUST button
until black bars display up to the salt level
number. For example, the pictures below show
the salt level at 6.

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 ion-exchanging.
It is much like a magnet attracting and holding
metals. Water without the hardness minerals (soft
water) flows out of the softener and into the house
soft water pipes.
¡
FILL: Salt, dissolved in water, is called brine.
Brine is needed to clean the hardness minerals from
the resin beads. To make the brine, 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 15). It takes place in 5 stages or cycles.
These are:

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 resin in the softener,
- -how fast the brine goes through the bed.
The nozzle and venturi (FIG. 6) 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.
resin bed lifted
and expanded
¢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.
¤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

After fast rinse, the softener returns to service. Hard
water goes into the resin tank where the resin bed

SOFT WATER SERVICE AND REGENERATION
AUTOMATIC BYPASS
ELECTRONICS
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 4:30 or 4:45 AM (depending on the salt type
setting, page 7), a time when not much water is used.
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 soften-
er, 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 recharge start-
ing time. 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 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. RE-
CHARGE TONIGHT displays until the regeneration
begins. When the regeneration begins, TONIGHT
goes off and *RECHARGE or RECHARGE TIME

* NOTE:
If the CLEAN feature is set to ON, a cleaning

display, along with the minutes of the clean cycle
remaining), precedes the recharge.

SALT¼ REFILLING STORAGE TANK/BREAKING A SALT BRIDGE
WHEN TO REFILL WITH SALT (or potassium
chloride): The Salt Monitor System (see page 10) will
turn the low salt light on to warn you when to refill
with salt. Check for a low salt light a few weeks after
you install the softener, and every week after that.
Always refill at about the #2 salt monitor level. At
this level, the tank is about 1/ 3 full. Never let the
softener use all the salt before refilling. Without salt,
you will soon have hard water. After filling, reset the
Salt Monitor System, page 10.
NOTE:
You will have a loss in softening capacity and may
get partly hard water if less than 10 inches (salt
monitor level 2) of salt is in the storage tank.
PLEASE SEE PAGE 9 FOR SALT FILLING DIRECTIONS.
BE SURE TO RESET THE SALT MONITOR, PAGE 10.
SALT BRIDGE
Sometimes, a hard crust or salt bridge forms in the
FIG. 9 SALT BRIDGE
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.

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.
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
softener as shown in FIG. 9. Make a pencil mark on
the handle, 1² or 2² 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 it.

Never use cleaners having ammonia or abrasives.
They may scratch and dull the surface.
NOZZLE & VENTURI
FIG. 10 CLEANING THE NOZZLE &
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.

water pressure at nozzle and venturi), then turn off
the cap from the nozzle and venturi housing. Do not
lose the large o-ring seal. Lift out the screen support and
screen, then the nozzle and venturi. Wash and rinse

IRON FROM THE 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
allowed in the specifications on page 20. 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
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, 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.

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 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. Refer to FIG. 12 on page 20. 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.

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. Re-
move 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. 69, on page
32). Separate the softener from the copper tubes,
or from the 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 use
it. Plug the inlet and outlet with rags to keep dirt,
bugs, etc. out.
6. Remove the brinewell cover and disconnect the
brine valve tubing at the nozzle and venturi
assembly (see page 32). Lift the brine valve out of
the brinewell. Tip the brine valve upside down to

the #1 SELECT button to enter the diagnostic display.
1. Press the ON/ OFF-HOLD button and hold in for
3 seconds. RECHARGE NOW and FILL begin to
flash (or clean backwash begins, if set) as the
softener enters the fill cycle of regeneration.
When FILL is on steady, remove the brinewell
cover and, using a flashlight, observe fill water
entering the tank.
5. To return the softener to service, press ON/ OFF-
HOLD.

¼ defective nozzle and venturi seal.
¼ 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.

approved silicone grease. To install the rotor seal,
first place the seal into the valve groove, rounded
side down (see cross-section). Apply a light coating
of silicone grease to the seal’s crossing ribs. Then,
carefully center the wear strip on the seal, and push it
downward onto the seal.

rotor in the valve body, on the rotor seal.
Lubricate the gear on the motor, and the valve cam
gear with Molykote grease, or other high quality gear
lubricant.
Lower the cover onto the valve body and rotor shaft.
Then install the cover holding screws. Before tight-
ening the screws, install the valve cam and gear.
Then, turn the rotor (clockwise only) to service
position. Tighten the screws using a criss-cross
pattern. If a torque wrench is available, torque to
30-40 inch pounds.
Be sure to orient switch as shown, with lever toward
the cam.

Hard water enters the valve inlet port. Internal valve porting routes the

softened as it passes through the resin bed, then enters the bottom
distributor. Soft water flows back into the valve and out the valve outlet, to
the house soft water pipes.

To begin a regeneration, the 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.

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.

During FAST RINSE, the rotor & disc is positioned so water flow enters the
