SECTION 1 WATER SOFTENER START-UP
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, stor-
age, installing and operating, bacteria could get
into the softener. For this reason, sanitizing as
follows is suggested (17when installing.
1. Lift the salt hole cover and use a pail or hose
to fill the salt storage tank with at least 3
gallons of water.
o
Remove the brinewell cover (FIG. 3) and
pour about 3/4 ounce of common 5.25%
household bleach (Clorox, Linco, BoPeep,
White Sail, Eagle, etc.) in the softener brine-
well.
o Press the ON/OFF-HOLD button and holdfor
3 seconds to start a recharge. This first re-
charge does several things.
- It draws the bleach into and through the
softener to sanitize it.
- It fills the salt tank to the water level need-
ed.
- It gets all the air out of the resin tank.
- It makes the resin bed (see page 11) ready
for service.
NOTES:
This recharge takes about 2 hours.
You can sanitize the softener with or with-
out salt in the storage tank.

SECTION 1 WATER SOFTENER START-UP
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.
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 19. Be sure to set the
salt monitor system (see page 10).
NOTES:
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 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 15) occurs more often when conditions
are humid.
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 so-
dium 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 2-1/2 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 8, the softener will be giving you soft water.

SALT MONITOR SYSTEM
The face plate 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:
1, Lift the salt hole cover and level the salt in the
storage tank.
e
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.
NOTE: To light the salt storage area, press the
TANK LIGHT button on the face plate.
o
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.
e
Finally, set the level you want the low salt
indicator light to come on. Press the SIGNAL
LIGHT ADJUST button until a (÷) shows
opposite this number. In the example below,
the light will come one when the stored salt
drops to level 2. At level 2, the storage tank is
about 1/3 full. This is the lowest you should
allow the stored salt level to drop to. To turn
the salt monitor off, press the button until
OFF shows.

If electrical power to the softener goes off, the
time display is blank but the face plate timer
keeps the correct time for about 72 hours. When
electrical power comes on again, you have to
reset the present time only if the display is
flashing. The HARDNESS and RECHARGE
TIME never require resetting unless 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, regenerations may
occur at the wrong time of day until you reset the
timer to the correct time of day.

SECTION 2 HOW YOUR WATER SOFTENER WORKS
2B. SOFT WATER SERVICE AND REGENERATION
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. 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.
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 14). It takes
place in 5 stages or cycles. These are:
_-1 FILL [] BACKWASH

[] 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 regenera-
tion. 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.

SECTION 2 HOW YOUR WATER SOFTENER WORKS
2B. 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.
[BBRINE 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 the length of time they take,
relative to the fill cycle length.

I I
2B. SOFT WATER SERVICE AND REGENERATION
AUTOMATIC BYPASS
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 watm, if possible, because the water heater
will refill with hard water. The softener regener-
ates from 2:00 AM to about 4:00 AM, (you can set
anytime), a time when not much water is used.
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.
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
circuit board. It is programmed to know the
softener's capacity (how many grains of hard-
ness 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.
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 the
most efficient salt usage.
Softening capacity is used as hard water goes
through the softener and hardness minerals are
removed, capacity is used. 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. RECHARGE TONIGHT
displays until the regeneration begins. When the
regeneration begins, TONIGHT goes off and
RECHARGE NOW flashes during the 2 hour
regeneration.

SECTION 3 CARE OF YOUR SOFTENER

3A. SALT. REFILLING STORAGE TANK/BREAKING A SALT BRIDGE
WHEN TO REFILL WITH SALT: The Salt
Monitor System (see page 10) will turn on the
low salt light 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.
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 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 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.
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. 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.
If the wrong kind of salt made the bridge, take it
out. Then fill the tank with nugget or pellet salt
only.

SECTION 3 CARE OF YOUR SOFTENER
3B. KEEPING THE WATER SOFTENER CLEAN
COVERS
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.
NOTE:
Never use cleaners having ammonia or abra-
sives. They may scratch and dull the surface.
NOZZLE & VENTURI
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.
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), 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 the parts
in warm water until clean. If needed, use a small
brush to remove iron or dirt. Also check and
clean the gasket.

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
19. 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 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 maximum 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.

SECTION 3 CARE OF YOUR SOFTENER
3C. KEEP THE SOFTENER FROM FREEZING
11[_ ill
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 -
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.
e
Refer to FIG. 12 on page 19. 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.
4. Unplug the transformer at the wall outlet.
Remove the salt hole cover and the main
cover. Take off both drain hoses.
e
Carefully remove the large holding clips at
the softener inlet and outlet (see Key No. 61,
on page 30). Separate the softener from the
adaptors or bypass valve.
Go Remove the brinewell cover and disconnect
the brine valve tubing at the nozzle and
venturi assembly (see page 30). Lift the brine
valve out of the brinewell. Tip the brine valve
upside down to drain out water.
o
e
DRAIN WATER FROM THE
SOFTENER
Drain Wood Block
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 CAREFUL-
LY tip it over until the rim rests on the wood
block with the inlet and outlet over the drain.
Do not allow the softener _ 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.

SECTION 3 CARE OF YOUR SOFTENER
3D. HELPFUL 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.
NOTE:
1. Also read ERROR CODE, page 11.
2. If an error code is not dispIayed, press and holdthe #1 SELECT button until (example: 000- -) shows
in the display. Then, press the #1 SELECT again and hold until a flashing AR code appears. It must
show AR31. If AR 17, 22, 39 or 60 shows, the face plate computer is working on incorrect input and
would probably be the cause of the problem. To set AR31, press either the UP [] or DOWN {_)utton.
When AR31 shows, press the # 1SELECT to return a flashing 12:00 AM display. Reset the present time,
hardness number and recharge time, pages 6 and 7.
PROBLEM CAUSE CORRECTION

(RECHARGE NOW) button and hold for 3
seconds to start a regeneration (see page
10).
Check for loss of power due to any of
these and correct. With the power back
on, look at the time display and read
PROGRAM MEMORY, page 11.
Look at FIG. 12 on page 19. Move the
stem in a single valve to service. In a
3-valve bypass, open the inlet and outlet
valves, and be sure to fully close the
bypass valve.
Take apart and clean or replace damaged
parts (see page 16).
The drain hose must not have kinks, sharp
bends, or be raised too high above the
softener (see page 16 in your installation
manual).
Press and release the SELECT button
until HARDNESS shows in the display.
Read the hardness number in the display
and be sure the same grains per gallon
number is shown on your water analysis
report. See page 7 to reset. Press and
release the SELECT button until the
present time shows in the display.
Avoid using hot water during this time
because the water heater refills with hard
water (see Automatic Bypass, page 14).
Ask your Sears retail or catalog store for a
new water analysis. Then make a new
hardness number setting (page 7).
