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

brine is metered into the salt storage tank by the
softener. However, you must keep the tank filled
with salt.

Fill the tank with NUGGETor PELLETwater
softener salt. DO NOTuse 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

WATER SOFTENING SALT WITH IRON RE-
MOVING 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.
SODIUM INFORMATION: Water softeners using
sodium chloride for regeneration add sodium to
the water. Persons who are on sodium restricted
diets should consider the added sodium as part of
their overall sodium intake.
For example, if your water supply is 15 grains
hard, you would have to drink 3 quarts of softened
water to consume 335 milligrams of sodium. That
is equivalent to eating 2Ć1/2 slices of white bread.
Persons who are concerned about their drinking
water should consider a Sears Drinking Water
System that will remove or reduce in excess of
90% of the sodium and other drinking water
contaminants.
You have now finished the water softener start up. After the sanitizing recharge, on
page 7, the softener will be giving you soft water.

FACE PLATE TIMER FEATURES
TIMER “POWER-OUTAGE MEMORY” — If
electrical power to the timer goes off, the
memory" built into timer circuitry keeps all
settings for 6 hours (minimum) or more. The
display is blank and the softener will not
regenerate. When electrical power comes on, 1 of
2 things will happen.
2. Thedisplay will show a time, but it will be
flashing. The timer memory did not keep the
time settings and they must be reset (page 6).
The flashing display is to remind you to reset
the timer.
NOTE:
1. The present time of day will show, meaning the
timer memory has kept all settings.
When power comes on, the flashing display
returns to a time of 12:00 AM Sunday, then begins
to keep time again. If you do not reset all time
settings, the softener will regenerate 3 days each
week. However, regeneration will most likely be
on thewrong days and at thewrong time.
NOTE:
If the softener was in a regeneration when power
was lost, it will now finish thecycle.
If the softener was in a regeneration when power
went off, the valve will return to service position
without finishing the regeneration cycle. If your
water tastes salty:
-- useRECHARGE NOW (sepage9) to start
another regeneration, or
-- open 1 or more soft water faucets and allow to
run until thesalt tasteis gone.

2B. SOFT WATER SERVICE AND REGENERATION
SERVICE
REGENERATION
When the softener is giving you soft water, it is
called Service". During service, hard water comes
from the house main water pipe into the softener.
Inside the softener resin tank is a bed made up of
thousands of tiny, plastic resin beads (FIG. 7). As
hard water passes through the bed, each bead
attracts and holds the hardness minerals. This is
called ionĆexchanging. It is much like a magnet
attracting and holding metals. Water without the
hardness minerals (soft water) flows out of the
softener and into the house soft water pipes.
ꢀFILL: Salt, dissolved in water, is called brine.
Brine is needed to clean the hardness minerals
from the resin beads. To make the brine, soft water
flows into the salt storage area during the fill cycle
as shown in FIG. 8.
The length of the fill cycle is factory set to provide
softening capacity for an average family. You can
reset this time when fineĆtuning" the water
softener, pages 18 through 20.
FIG. 8 WATER FLOW THROUGH THE
After a period of time, the resin beads become
coated with hardness minerals and they have to be
cleaned. This cleaning is called recharge, or
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 nozzle and venturi (FIG. 9) makes the suction
to take brine from the salt tank and put it into the
resin tank. It keeps 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 goes 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 tankto the drain.
ꢃFAST 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. 11).

2B. SOFT WATER SERVICE AND REGENERATION
AUTOMATIC BYPASS
If you get up early in the morning and you can
hear the softener regenerating, change the time
setting. Set the recharge time to 12:00 AM or 1:00
AM (page 18). 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.
During the brining, brine rinse and backwash
cycles of regeneration, HARD water goes through
the softener valve and to the house pipes. If a
faucet is opened, hard water is there for your
needs. However, you should not use HOT water, if
possible, because the water heater will refill with
hard water. The softener regenerates from2:00
AM to about 4:00 AM, (you can set anytime), a time
when not much water is used.

SECTION 3
3A. SALT… REFILLING STORAGE TANK/BREAKING A SALT BRIDGE
WHEN TO REFILL WITH SALT: Check the salt
level a few weeks after you install the softener and
every week after that. Refill when the storage
tank is about 1/3 full. Never let the softener use
all the salt before refilling. Without salt, you will
soon have hard water.
IMPORTANT:
You will have a loss in softening capacity and
may get partly hard water if less than 10
inches of salt is in the storage tank.
PLEASE SEE PAGE 8 FOR SALT FILLING DIRECTIONS.
SALT BRIDGE
Sometimes, a hard crust or salt bridge forms in the
FIG. 12 A 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.
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.
Pencil
Mark
Broom Handle
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. 12. 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 pushinto the bridge in a few
places to break it. Do not try to break the salt
bridge by pounding on the outside of the salt
tank. You may damage it.

KEEPING THE WATER SOFTENER CLEAN
COVERS
NOTE:
To keep your new Sears water softener looking
nice, apply a coat of paste wax and repeat once a

keep it sparkling.
Never use cleaners having ammonia or abrasives.
They may scratch and dull the surface.
NOZZLE AND VENTURI
FIG. 13
A clean nozzle and venturi (FIG. 13) 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.

IRON FROM THE RESIN BED
water iron, an iron filter or other equipment is
needed. Your local Sears store has trained people
to help you with iron water problems.
Your water softener takes hardness minerals
(calcium and magnesium) out of the water. Also, it
can control some clear water" iron0see maximum
allowed in the specifications on page 21. 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 NOTremove any iron which makes
the water cloudy or rusty as it comes from the
faucet (called red water iron). To take red water
iron out of water, or over the maximum of clear
If your water supply has clear water iron, even
though less than the maximum allowed, regular
resin bed cleaning is needed. Sears has resin bed
cleaner, Stock No. 42Ć34426 for this. Clean the bed
at least every 6 months. If iron shows up in the soft
water before 6 months, clean more often. Printed
instructions are on the resin bed cleaner bottle.

carefully.
TO SET THE TIMER FOR DAYS OF REGEN-
ERATION AND FILL MINUTES, DO THE FOL-
LOWING.
NOTE:
Remember, the timer is factory set for Monday,
Wednesday and Saturday regenerations starting at
2:00 AM. Fill time is factory set for 16 minutes.
To have soft water all the time, the softener must
regenerate, or recharge a certain number of times
in each 7 day period. How many times to
regenerate (set the timer) depends on 3 things.
1. SET DAYS AND TIME OF REGENERA-
TION, OR RECHARGE
1. The number of people in your home Ċ tells
you how much water is used.
a. Press the RECHARGE TIME button ꢀ once to
display the factory set regeneration days and
starting time (flashing). To change the regenĆ
eration start time, do step b following. OtherĆ
wise go to step c.
2. The grains per gallon (GPG) hardness of your
water supply Ċ listed on your water analysis
report (see page 2 in your Installation Manual,
or page 2 of this manual).
FIG. 15
NOTE:
If your water supply contains iron, compensate for
it by adding to the water hardness number. For
example, assume your water is 15 gpg hard and
contains 2 ppm iron. Add 5 to the hardness
number for each 1 ppm of iron. In this example,
you would use 25 for your hardness number.

3. How much salt is used each regeneration Ċ
determined by the length of the fill cycle (see
pages 19 and 20).
REGENERATION TABLE: The table (page 20)
makes it easy fo you to pick the best regeneration

5E. 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 solid state 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.

SECTION 5
5E. WATER FLOW THROUGH THE SOFTENER VALVE
BRINING AND BRINE RINSE CYCLES
After fill, timer/switch action allows the motor to turn the rotor and disc into BRINING position. Water
flow is directed to the nozzle. Suction, created by the nozzle and venturi, draws brine from the salt
storage tankand injects it into the resin bed via the bottom distributor. Flow continues out the top
distributor and to the drain. Hard water is available at the valve outlet.
When the brine valve closes to end brine draw, water flow continues in the same directions to slowly
RINSE brine from the resin bed and to the drain.
BACKWASH CYCLE
Timer/switch action again allows the motor to turn the rotor & disc to place
the valve in BACKWASH, stopping water flow to the nozzle. Water is routed
down and out the bottom distributor, up through the bed, and out the top
distributor to the drain. The fast flow (controlled by a flow plug in the drain
fitting) flushes dirt, sediments, iron deposits, remaining brine and hardness
to the drain.

FAST RINSE CYCLE
During FAST RINSE, the rotor & disc is positioned so water flow enters the resin tank
through the top distributor, and exits through the bottom distributor, to the drain.
The solid state timer again energizes the motor to return the valve to service, and as the
valve rotates, the position switch lever drops to open the circuit. The valve remains posiĆ
tioned in service until the timer initiates the next regeneration.
