1D. ,,, SANBTiZING 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
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 (FIG 2) and pour
about 3/4 ounce of common 5.25% household
bleach (Clorox, Linco, BoPeep, White Sail, Eagle,
etc.) in the softener bdnewell.
3. Press the ON/OFF.HOLD button and bold 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 service.
NOTES:
This recharge takes about 2 hours.
You can sanitize the softener with or without
salt in the storage tank.

1E. RLL 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
f'd]iedwith 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
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.
ADD SALT

\Brinewett
Cover
Sodium Infcrrmation: 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 2-112 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.

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

2B. SOFT WATER SERVICE AND REGENERATION
i=======_==_== .... _, ,,,, _,, ,,,.,,,.,,,,_,, ,,,, =, _,, i
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:

[_]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 ill! 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

2Bo SOFT WATER SERVICE AND REGENERATION
[]BRINING: During brining, the brine is moved
from the salt storage area, into the resin rank,
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 WIG 6) make suction to
move brine from the salt tank into the resin tank.
They keep the brine flow down to a very slow rate
to get the best rosin 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 bnne flush from the resin
tank to the drain. Brining and brine rinse together
vary in length of time they take, relative to the fit!

_EC'T_ON 2HOW YOUR WATER SOFTENER WORKS
I f
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 wilt 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 paKs 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 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 set), it wilt 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.

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 I13 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 toot, 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
tanl_=
If the wrong kind of salt was the cause of the
bridge, take itout. Then fill the tank with nugget or'
pellet salt only.

year'. When dusty, wipe it with a damp cloth to
keep it sparkling
NOZZLE AND VENTURi
A clean nozzle and venturi (FIG.. 10) is a must for
the softener to work fight. 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 covet: 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

IRON FROM THE RESBN 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 Seats 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 dais. 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

3C. KEEP THE SOFTENER FROM FREEZING
u Ulll. ii,
If the softener is installed where it could fi-eeze
(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
mIf a single bypass valve is insta!led, 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. Careful!y remove the large holding clips at the
softener" inlet and outlet (see Key No, 61, on
page 30) Separate the softener fi'om the
adaptors or bypass valve
.Remove the brinewell cover and disconnect
the brine valve tubing at the nozzle and venturi

... 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. tf an error code is not dispIayed, press and holdthe SELECTbutton untit
(example: 000- -) shows in the display. Then, press SELECT again and hold until an SR code appears. It
must show SR 22. If any other' SRnumber shows, the softener computer' is working on incorrect input and
this would probably be the cause of the problem.. To set SR22, press either the UP [] or DOWN[;_button_
Then, press SELECT to return a flashing 12:00 AM display, and reset the timer' on page 6.
PROBLEM CAUSE CORRECTION
No soft water Faucet or fixture may be plumbed to From the outlet of the water softener, trace the water flow
hard water _aths 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.
No salt (or saR bridged) in the storage Refill with salt, or break the salt bridge (page 14). Press

Look at FIG, 12 on page 18,,Move the stem in a single
valve to service. In a 3waive 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?
If display is blank, check power source to the
softener,
- If time is flashing, power was off' for over 6 hours The
softener resumes no[maI operation but regenerations
occur at the wrong time,
- If an error code (Example: Err 03) shows in the face
plate display, go to Automatic Electronic DiagnostiCs
2. Plumbing bypass valve(s) must be in Full Service
position.

The inlet and outlet pipes must connect to the softener
valve inlet and outlet respectively
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'
REMOVETHETOP COVER ANDSALTTANKCOVER
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
househotd'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 SEIECT 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 £ t '=" .....
computer monitors the electronic {Fj% '= D_
components and circuits for cor- I
rect operation. Ifa 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 err'or code appears in the display, all face
plate buttons are inoperable except the SEI_ECT
button The SELECTbutton remains operational so
the service person can make the Manual Initiated
Electronic Diagnostics to further isolate the defect,
and check the water meter.
