HAROMCSS

For example, assume your water is 15 gpg hard
arid contains 2 ppm iron. Add 5 to the haidness
number for eac/71 ppm of iron. In ffiis example,
you would use 25 for your hardness number.

1D.

Care is taken at the factory to keep your water
softener clean and sanità^. Materials used to
make the softener will not infect or contaminate
your water supply, and will not c^se 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 1
gallon of water.

SANITIZING THE WATER SOFTENER

2. Remove the brinewell cover {FIG. 2) and

pour about 3/4 ounce of cximmon 5.25%
household bleach (Clorox, Unco, BoPeep,
White Sail, Eagle, etc.) in the softener
brinewell.

3. Press the ON/OFF-HOLD button and hold for

3 seconds to start a recharge. This first

recharge does several things.

FIG. 2

ADD WATER

— 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 die resin bed (see page 11}

ready for service.
NOTE:
This recharge takes about 40 minutes.

Recommended by the Water Quality Association. On

some water supplies, the water softener may need pe
riodic di^nfecting. Sanitize wi№ or without salt in the
storage tank.

SECTION 1

1E. FILL THE STORAGE TANK WITH SALT

WATER SOFTENER START-UP

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 fiiled
with sait.

Fiil the tank with NUGGET or PELLET water
softener sait DO NOT use rock saits, as they
have dirt and sediments that wili stop the
softener from working.

Before fiiiing, be sure the brineweli cover is in

place on the top of the brineweli. Salt storage
capacity is shown on page 18.

NOTE:
in humid areas, it is best to fii! the storage tank

haif-fuii, and to refill it more often. Salt bridging
(see page 14) occurs more often when condi
tions are humid.

WATER SOFTENING SALT WITH IRON RE
MOVING ADDITIVES — Some saits have an
additive to help the softener handle iron in the
water suppiy. Aithough this additive may help to

keep the softener resin clean, it may also release
corrosive fumes that wiil weaken and shorten the
iife of some softener parts.

FIG. 3 ADD SALT

CkftfMUlBJt

Ccwer

SODiUM INFORMATiON: Water softeners us
ing sodium chioride for regeneration add sodium

to №e water. Persons who are on sodium

restricted diets shouid consider the added so

dium as part of their overaii sodium intake.

For exampie, if your water sujoply is 15 grains
hard, you would have to drink 3 quarts of
soften^ 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 wili 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 SANlTiZlNG RE
CHARGE, ON PAGE 8, THE SOFTENER WILL BE GIVING YOU SOFT WATER.

HOW YOUR WATER SOFTENER WORKS

2A.

E)CTRA 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 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 button and hold

for 3 seconds. The softener
enters the fill cycle of regen

eration right away.. .the dis
play shows “FillinG NOW”.

This regeneration will last for

about 40 minutes. Then, you

will have soft water again.

RECHARGE TONIGHT

■ Press and release (DO NOT HOLD) the

ON/OFF-HOLD button. RE
CHARGE TONIGHT flashes
in the display, and the soften
er begins regeneration at the
next preset recharge time. Press and release

the ON/OFF-HOLD button once more if you
decide to cancel the regeneration, and RE

CHARGE TONIGHT.

FACE PLATE TIMER FEATURES

Ft III nS

MOW

3* 15'

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.

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 present time
of day, please call you local

Sears Service Department for
service.
