1D. SANITIZING THE WATER SOFTENER
Care is taken at the factory to keep your water
softener clean and sanitaw. 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.
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.
2. Lift the salt hole cover and use a pail or hose to fill
the salt storage tank with at least 3 gallons of water.
3. Remove the brinewell cover and pour about 3/4
ounce, or ] to 2 tablespoons, of common 5.25%
household bleach (Clorox, Linco, BoPeep, White
Sail, Eagle, etc.) in the softener brinewell.
4. Press the ON/OFF-HOLD button and holdfi_r 3
seconds to start a recharge. This first recharge does
several things.
I It draws the bleach into and through the soft-
ener to sanitize it.
I It fills the salt tank to the water level
needed.
I It gets all the air out of the resin tank.
I 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 without
salt in the storage tank.

SECTION 1 wATERSOFTENERSTART-UP
I I
1E. FILL THE STORAGE TANK WITH SALT
Brine (salt dissolved in water) is needed for each and
eveu regeneration. The water for making brine is
metered into the salt storage tank by the softener.
However, you must keep tile 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.
Water softening salt with iron removing addi-
tives -- 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.
ADD SALT
Brinewell
Cover
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 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.

EXTRA RECHARGE
Sometimes, a manually started regeneration (re-
charge) may be desired, or needed. Two examples
aye:
-- 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 fight away, or you can
set the timer to regenerate at the next 2:00 AM (or
other preset recharge time). Do the following.
RECHARGE NOW
• Press the ON/OFF--HOLD

• _ I|_p M
RECHARGE NOW begins to RECHARGENOW
flash in the display, and the
softener enters the fill cycle of regeneration right
away. This regeneration will last for about 2
hours. Then, you will have soft water again.
RECHARGE TONIGHT
• Press and release (do not
hold) the ON/OFF-HOLD but- ] 3:18 TM
ton. RECHARGE TONIGHT RECHARGETONIGHT
flashes in the display, and the
softener begins regeneration at the next preset
recharge time. If you decide to cancel the regen-
eration before it has started, press and release the
ON/OFF-HOLD button once more to turn off the
flashing RECHARGE 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 clay until you reset the timer to the
correct time of day.
ERROR CODE
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 clay, please
call you local Sears Service Department for service.

2B. SOFT WATER SERVICE AND REGENERATION
SERVICE
When the softener is giving you soft water, it is called
"Service". During service, hard water flows through
the house main water pipe and into the softener.
Inside of 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
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.

2B. SOFT WATER SERVICE AND REGENERATION
EZ]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
move brine from the salt tank into the resin tank.
They keep the brine flow down tO a veI3r slow rate tO
get the best resin cleaning with the least salt.
[] BRINE RINSE: After all of the brine is sucked OUt
of the salt tank, the brine valve closes. Water keeps
flowing through the resin tank 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.

After fast rinse, the softener returns tO service. Hard
water goes into the resin tank where the resin bed
again takes out the hardness minerals. Soft water
goes to the house soft water pipes.

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 ff)r 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 ]2:00 AM or ] :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 m_dn parts of the softeneffs electronics are [] a
WATER METER, and [] a COMPUTER.
[] WATER METER I 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 I The computer is part of the timer
circuit board. It is programmed to know the
softeneffs 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 groins per gallon (gpg)
hardness of the water.
To find a regeneration pattern best for your needs,
the computer uses: (]) 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 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 se0, it will schedule a regeneration.
_CtlARGE TONIG[IT displays until the regenera-
tion begins. When the regeneration begins, TO-

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 dusty, wipe it with a damp cloth to keep it
sparkling.
NOTE:
Never use cleaners having ammonia or abrasives.
They may scratch and dull the surface.
NOZZLE AND VENTURI
A clean nozzle and venturi (FIG. ] 0) 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 I 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 anti 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 (cal-
cium and magnesium) out of the water. Also, it can
control some "clear water" iron. See maximum
allowed in the specifications on page ] 8. With clear
water iron, water from a faucet is clear when first put
into a glass. After ] 5 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 eve1T 6 months. If iron appears in the soft water
before 6 months, clean more often. Printed instruc-
tions are on the resin bed cleaner bottle.

SECTION 3 CARE OF YOUR SOFTENER
I I
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.
2. Open a faucet in the soft water pipes to vent
pressure in the softener.
e
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.
6.
Carefully remove the large holding clips at the
softener inlet and outlet (see Key No. 6], on page
30). Separate the softener from the adaptors or
bypass valve.
7. 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.

Looking at FIG. ] ], 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 zuatc__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.

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 ] 0.
2. If an error code is not 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 SR 17. 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 1.7, press either the UP (_ or DOWN[_buEon. Then, press SELECT to return a flashing
12:00 AM display, and reset the umer on page 6.
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.
Manual bypass valve(s) in bypass
position
Dirty, plugged or damaged nozzle &
venturi
Valve drain hose plugged
Water hard Hardness number setting too low
sometimes
Using hot water when softener is
regenerating
Increase in the grains of hardness in
your water supply
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.
Look at FIG. 12 on page 18. 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
15).
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
13).
Ask your Sears retail or catalog store for a new water
analysis. Then make a new hardness number setting
(page 7).

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 regen-
erations occur at the wrong time.
- If an error code (Example: Err 03) shows in the face
plate display, go to Azdomatic iZ/ectromic Dia/qmos-
tics.
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 flee 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 Mamlal Initiated Electronic Diagnostics, and the

with salt contact.
A. If the softener does not draw brine:
- nozzle and/or venturi dirty or defective.
- nozzle and venturi not seated properly on gas-
ket.
- restricted drain (check drain fitting and hose).
- defective nozzle and venturi seal.
- other inner valve defect (rotor seal, rotor &
disc, wave washer, etc.).

lubricant.
Be sure to orient the switch as shown, with the lever
toward the cam.
DISASSEMBLY
To remove a part or group of parts, refer to the valve
drawing. A common screwdriver or nut driver,
Phillips screwdriver and pliers are the only tools
needed to completely disassemble.
SERVICING THE VALVE
Inspect all (:)-rings, seals and gaskets for wear or
defects.
Inspect the bottom surface of the rotor and disc for
scratches, chips or wear.
NOTE: If replacement is needed, be sure tO use the
current replacement part.
ASSEMBLY
Be sure all parts are in place and in the proper
position. Lubricate ALL ()-rings and seals with FDA
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.
Install the nozzle and venturi seal and drain seal.
Assemble 2 ()-rings and the wave washer onto the
rotor and disc. Then center the rotor and disc, in the
valve body, on the rotor seal.

1D. SANITIZING THE WATER SOFTENER
Care is taken at the factory to keep your water
softener clean and sanitaw. 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.
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.
2. Lift the salt hole cover and use a pail or hose to fill
the salt storage tank with at least 3 gallons of water.
3. Remove the brinewell cover and pour about 3/4
ounce, or ] to 2 tablespoons, of common 5.25%
household bleach (Clorox, Linco, BoPeep, White
Sail, Eagle, etc.) in the softener brinewell.
4. Press the ON/OFF-HOLD button and holdfi_r 3
seconds to start a recharge. This first recharge does
several things.
I It draws the bleach into and through the soft-
ener to sanitize it.
I It fills the salt tank to the water level
needed.
I It gets all the air out of the resin tank.
I 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 without
salt in the storage tank.

SECTION 1 wATERSOFTENERSTART-UP
I I
1E. FILL THE STORAGE TANK WITH SALT
Brine (salt dissolved in water) is needed for each and
eveu regeneration. The water for making brine is
metered into the salt storage tank by the softener.
However, you must keep tile 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.
Water softening salt with iron removing addi-
tives -- 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.
ADD SALT
Brinewell
Cover
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 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.

EXTRA RECHARGE
Sometimes, a manually started regeneration (re-
charge) may be desired, or needed. Two examples
aye:
-- 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 fight away, or you can
set the timer to regenerate at the next 2:00 AM (or
other preset recharge time). Do the following.

• _ I|_p M
RECHARGE NOW begins to RECHARGENOW
flash in the display, and the
softener enters the fill cycle of regeneration right
away. This regeneration will last for about 2
hours. Then, you will have soft water again.
RECHARGE TONIGHT
• Press and release (do not
hold) the ON/OFF-HOLD but- ] 3:18 TM
ton. RECHARGE TONIGHT RECHARGETONIGHT
flashes in the display, and the
softener begins regeneration at the next preset
recharge time. If you decide to cancel the regen-
eration before it has started, press and release the
ON/OFF-HOLD button once more to turn off the
flashing RECHARGE 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 clay until you reset the timer to the
correct time of day.
ERROR CODE
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 clay, please
call you local Sears Service Department for service.

2B. SOFT WATER SERVICE AND REGENERATION
SERVICE
When the softener is giving you soft water, it is called
"Service". During service, hard water flows through
the house main water pipe and into the softener.
Inside of 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
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.

2B. SOFT WATER SERVICE AND REGENERATION
EZ]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
move brine from the salt tank into the resin tank.
They keep the brine flow down tO a veI3r slow rate tO
get the best resin cleaning with the least salt.
[] BRINE RINSE: After all of the brine is sucked OUt
of the salt tank, the brine valve closes. Water keeps
flowing through the resin tank 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.

After fast rinse, the softener returns tO service. Hard
water goes into the resin tank where the resin bed
again takes out the hardness minerals. Soft water
goes to the house soft water pipes.

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 ff)r 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 ]2:00 AM or ] :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 m_dn parts of the softeneffs electronics are [] a
WATER METER, and [] a COMPUTER.
[] WATER METER I 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 I The computer is part of the timer
circuit board. It is programmed to know the
softeneffs 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 groins per gallon (gpg)
hardness of the water.
To find a regeneration pattern best for your needs,
the computer uses: (]) 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 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 se0, it will schedule a regeneration.
_CtlARGE TONIG[IT displays until the regenera-
tion begins. When the regeneration begins, TO-

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 dusty, wipe it with a damp cloth to keep it
sparkling.
NOTE:
Never use cleaners having ammonia or abrasives.
They may scratch and dull the surface.
NOZZLE AND VENTURI
A clean nozzle and venturi (FIG. ] 0) 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 I 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 anti 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 (cal-
cium and magnesium) out of the water. Also, it can
control some "clear water" iron. See maximum
allowed in the specifications on page ] 8. With clear
water iron, water from a faucet is clear when first put
into a glass. After ] 5 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 eve1T 6 months. If iron appears in the soft water
before 6 months, clean more often. Printed instruc-
tions are on the resin bed cleaner bottle.

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.
2. Open a faucet in the soft water pipes to vent
pressure in the softener.
e
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.
6.
Carefully remove the large holding clips at the
softener inlet and outlet (see Key No. 6], on page
30). Separate the softener from the adaptors or
bypass valve.
7. 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.
8.
9.
DRAIN WATER FROM THE
SOFTENER
drain wood block
Looking at FIG. ] ], 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 zuatc__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.

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 ] 0.
2. If an error code is not 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 SR 17. 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 1.7, press either the UP (_ or DOWN[_buEon. Then, press SELECT to return a flashing
12:00 AM display, and reset the umer on page 6.
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.
Manual bypass valve(s) in bypass
position
Dirty, plugged or damaged nozzle &
venturi
Valve drain hose plugged
Water hard Hardness number setting too low
sometimes
Using hot water when softener is
regenerating
Increase in the grains of hardness in
your water supply
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.
Look at FIG. 12 on page 18. 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
15).
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
13).
Ask your Sears retail or catalog store for a new water
analysis. Then make a new hardness number setting
(page 7).

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 regen-
erations occur at the wrong time.
- If an error code (Example: Err 03) shows in the face
plate display, go to Azdomatic iZ/ectromic Dia/qmos-
tics.
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 flee of kinks and sharp
bends, and not elevated over 8 ft. above the floor.
REMOVE THE TOP COVER AND SALT TANK COVER
