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 q) when installing.

The water for making
brine is metered into the salt storage tank by the
softener. However, you must keep the tank filled
with 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 brinewen. Salt storage
capacity is shown on page 18.

In humid areas, it is best to fill the storage tank
half-full, and to refill it more often. Salt bridging
(see page 14) occurs i-ilorc often when conditions
are humid.

WATER SOFTENING SALT WITH IRON REMOVING ADDITIVES -- Some salts have an additive to
hel I) 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 overan sodium intake.

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.

E]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
watec 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 13). It takes place in
5 stages or cycles. These are:

WATER FLOW THROUGH THE
SOFTENER IN BACKWASH

[_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 fi'om the salt tank and put it into the
resin tank. They keel) 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 tank to the drain.
Brining and brine rinse together vary in 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).

WATER FLOW THROUGH THE
SOFTENER IN BRINING AND

[] BACKWASH: During backwash, water flows I_P
through the resin tank (FIG. 7) at a fast rate to flush

to the drain. The bed lifts and expands fbr good
cleaning.

SOFT WATER SERVICE

AND REGENERATION

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 fbr your
needs. However, you should not use HOT water, if
possible, because the water heater will refill with
hard water. The softener regenerates
from 2:00
AM to about 4:00 AM, (you can change this time...
see page 7), a time when not much water is used.

Two main parts of the softener's electronics
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 pml of the
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, 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 time
setting. 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 to provide you with soft
water fbr the longest time, 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. RECI_IARGE TONIGI_ITdisplays until
the regeneration begins. When the regeneration
begins, TONIGHT goes off and RECHARGE NOW
flashes during the 2 hour regeneration.

CARE OF YOUR SOFTENER

SALT...REFILLING

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 beff)re refilling. Without salt, you will
soon have hard water.

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 9 FOR SALT FILLING DIRECTIONS.

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.

If the wrong kind of salt made the bridge, take it
out. Then fill the tank with nugget or pellet salt
only.

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.

push tool into salt
bridge to break

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, 1" or 2" below the top height
of the rim, as shown. 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.

CARE OF YOUR SOFTENER

THE WATER SOFTENER

To keep your new Sears water softener
looking
nice, apply a coat of paste wax and repeat once a
year. When dusty, wipe it with a damp cloth to
keep it sparkling.

Never use cleaners having ammonia or abrasives.
They may scratch and dull the surface.

NOZZLE AND VENTURI

A clean nozzle and venturi (FIG. 10) is a must for
the softener to work right. This small unit moves
brine fi'om 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 haM water.

IRON FROM THE RESIN BED
Your water softener takes hardness
minerals
(calcium and magnesium) out of the water. Also, it
can control some "clear water" iron. See maximum
allowed in the specifications on page 18. 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

To get to the nozzle and venturi,
remove
the
softener top cover. Be sure the softener is in

venturi). Then, holding the housing tightly with 1
hand, turn the cap off. DO NOT LOSE THE IARGE

needed, use a sman brush to remove iron or dirt.
Also check and clean the gasket.

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 maxinmm allowed, regular
resin bed cleaning is needed. Sears has resin bed
cleaner, Stock 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.

HINTS 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
yourself and you won't have to call and wait for service. If, after making the checks, your softener still does
not work right, call your Sears Service Department,
or call toll free, number 1-800-426-9345
for telephone
assistance.

NOTE:
Also read ERROR CODE, page 10. If an error code is trot dispIayed, press and bold the SELECT button until
(example: 000- -) shows in the display. Then, press SELECT again and bold until an SR code appears. It
must show SR21. If any other SR number shows, the softener computer is working on incorrect input and
would probably be the cause of the problem. To set SR21, press either the UP {_)r DOWN {_utton. Then
press select to return a flashing 12:00 AM display, and reset the timer, page 6.
