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[] when 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.
2. Remove the brinewell cover and pour about
3/4 ounce (1 to 2 tablespoons) of common 5.25%
household bleach into the softener brinewell.
Clorox, Linco, BoPeep, White Sail, Eagle, etc., are
brand names of bleach readily available.
3. Press the ON/OFF-HOLD button and hold for3
seconds to start a recharge. This first recharge
does several things.
-- It draws the bleach into and through the
softener to sanitize it.
-- It fills the salt tank to the water level
needed.
-- It gets all the air out of the resin tank.
-- It makes the resin bed (see page 11) ready
for soft water service.

[] Recommended by the Water Quality Association. On
some water supplies, the water softener may need
periodic disinfecting. Sanitize with or without 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 18.
NOTE:
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 more often when conditions
are humid.
ADD SALT
\
Brinewell
Cover
Water softening salt with iron removing addi-
tives -- Some salts have an additive to help the
softener handle iron in the water supply. Al-
though 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 RE-
CHARGE, ON PAGE 8, THE SOFTENER WILL BE GIVING YOU SOFT WATER.

EXTRA RECHARGE
Sometimes, a manually started regeneration
(recharge) may be desired, or needed. Two
examples are:
- - You have used more water than usual (guests
visiting) and you may run out of soft water
before the next timer started regeneration.
- - You did not refill the softener with salt before
it was gone.
You can start a regeneration right awa N or you
can set the timer to regenerate at the next 2:00
AM (or other preset recharge time). Do the
following.

softener enters the fill cycle
of regeneration right away. This regeneration
will last for about 2 hours. Then, you will
have soft water again.

er begins regeneration at the
next preset recharge time. If you decide to
cancel the regeneration before it has started,
press and release the ON/OFF-HOLD but-
ton once more to turn off the flashing RE-
CHARGE 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 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
you water soft. However, regenerations may
occur at the wrong time of day until you reset the
timer to the correct time of day.
ERRORCODE
An error code could appear in the face plate
display if a problem occurs in the softener
electronics. If you see an error code instead of the
time of da N please call you local Sears Service
Department for service.

SECTION 2 HOW YOUR WATER SOFTENER WORKS
2B. SOFTWATER 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 13). It takes
place in 5 stages or cycles. These are:

REGENERATION
[_ 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.

2B. SOFT WATER SERVICE AND REGENERATION
[] BRINING: Duringbrining, 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.
[_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 the length of time they take,
relative to the fill cycle length.

SECTION 2 HOW YOUR WATER SOFTENER WORKS

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 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). In most homes, 2-4 AM is a
time when not much water is used, if any.
If you get up early in the morning and you can
hear the softener regenerating, change the time
setting. Set the recharge start 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.
ELECTRONICS
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
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 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
capacitN 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 for 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. RECHARGE TONIGHT displays
until the regeneration begins. When the regen-
eration begins, TONIGHT goes off and RE-
CHARGE NOW flashes during the 2 hour regen-
eration.

SECTION 3 CAREOFYOURSOFTENER

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 9 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
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, 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 the
tank.
If the wrong kind of salt was the cause of the
bridge, take it out. Then fill the tank with nugget
or pellet salt only.

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 dust34 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 AND 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, holding the housing tightly with
1 hand, turn the cap off. 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.
Carefully replace all parts in the correct order.
Lubricate the o-ring seal with silicone grease or
Vaseline and place in position. Install and
tighten the cap, by hand only. Do not over-
tighten and break the cap or housing.

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 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 appears in the
soft water before 6 months, clean more often.
Printed instructions are on the resin bed cleaner
bottle.

SECTION 3 CAREOFYOURSOFTENER
3C. 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:
1. Close the shut-off valve on the house main
water pipe, near the water meter or pressure
tank.
o
o
Open a faucet in the soft water pipes to vent
pressure in the softener.
If a single bypass valve is installed, move the
stem into bypass. See FIG. 12 on page 18. In a
3-valve bypass system, close the inlet and
outlet valve 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.
5. Remove the salt hole cover and the main
cover. Take off both drain hoses.
o
o
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.
Remove the brinewell cover and disconnect
the brine valve tubing at the nozzle and
venturi assembly (see page 23). Lift the brine
valve out of the brinewell. Tip the brine valve
upside down to drain out water.
DRAIN WATER FROM THE
SOFTENER
Drain Wood Block
o
o
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.
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 CAREOFYOURSOFTENER
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, or call toll free, number 1-800-426-9345 for
telephone assistance.
NOTE:
1. Also read ERROR CODE, page 10.
2. If an error code is not dispIayed, press and hold the SELECT button until (example: 000- -) shows in
the display. Then, press SELECT again and hold until an SR code appears. It must show SR 22 for Model
Nos. 625.348471 and 625.348491. If any other SR number shows, the softener computer is working on
incorrect input and this would probably be the cause of the problem. To set SR 22, press either the UP_
or DOWNW button. Then, press SELECT to return a flashing 12:00 AM display; and reset the timer on
page 6.
You can find the model number of your water softener on the rating decal, on the brine tank rim. See
page 28.
PROBLEM
No soft water CAUSE
Faucet or fixture may be plumbed to
hard water
No salt (or salt bridged) in the
storage tank
Transfomer unplugged at the wall
outlet, or power cable leads loose,
fuse blown, circuit breaker popped,
or circuit switched off.
CORRECTION
From the outlet of the water softener, trace the water flow paths
in your house pipes. If soft water is not directed to a faucet or
fixture where it is wanted, consult a plumber. To conserve salt,
the installer may have isolated some fixtures (outside faucets,
toilets, etc.) from soft water.
Refill with salt, or break the salt bridge (page 14). Press
ON/OFF-HOLD (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 10.
Manual bypass valve(s) in bypass Look at FIG. 12 on page 18. Move the stem in a single valve
position to service. In a 3-valve bypass, open the inlet and outlet valves,
and be sure to fully close the bypass valve.
Dirty, plugged or damaged nozzle & Take apart and clean or replace damaged parts (see page 15).
venturi
Valve drain hose plugged
Water hard Hardness number setting too low
sometimes
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.
Using hot water when softener is Avoid using hot water during this time because the water
regenerating heater refills with hard water (see Automatic Bypass, page 13).
Increase in the grains of hardness in Ask your Sears retail or catalog store for a new water analysis.

ALWAYS MAKE THESE INITIAL CHECKS FIRST
1. Does the time display show the correct time of day?
2°
If display is blank, check power source to the
softener.
- If time is flashing, power was off for over 6 hours. The
softener resumes normal operation but regenera-
tions occur at the wrong time.
- If an error code (Example: Err 03) shows in the face
plate displa)_ go to Automatic Electn_nic Diagnostics.
Plumbing bypass valve(s) must be in Full Service
position.
3. The inlet and outlet pipes must connect to the softener
valve inlet and outlet respectively.
4. Is the transformer plugged into a "live", grounded
wall outlet, and is the power cable fastened securely?
5. The valve drain hose must be free of kinks and sharp
bends, and not elevated over 8 ft. above the floor.
REMOVE THE TOP COVER AND SALT TANK COVER
6. Is there salt in the storage tank?
7. Is the brine tubing connected? (See water flow
diagrams).
8. Is the brine valve float set right? (See page 22).
9. Press the SELECT button 2 times to display the
hardness setting. Be sure it is the correct setting for the
household's water supply. (Make a hardness test of
the raw water and compare with the hardness setting.
Also test a soft water sample to verify if a problem
exists.) Press SELECT twice more to return the time of
day display.
If you do not find the problem after making initial checks,
do the Manual Initiated Electronic Diagnostics, and the
Manual Advance Regeneration Check.

AUTOMATIC ELECTRONIC DIAGNOSTICS
The face plate computer has a self-diagnostic
function for the electrical system (except input
power and water meter). The _ _ n_
computer monitors the electronic _"_ UZJ I
components and circuits for cor- 1
rect operation. If a malfunction occurs, an error
code appears in the face plate display.
The chart below shows the error codes that could
appear, and the possible defects for each code.
While an error code appears in the display, all face
plate buttons are inoperable except the SELECT
button. The SELECT button remains operational so
the service person can make the Manual Initiated
Electronic Diagnostics to further isolate the defect,
and check the water meter.
