▲ Read all steps, guides and rules carefully before
installing and using your new water softener. Follow
all steps exactly to correctly install. Failure to follow
them could cause personal injury or property damage.
Reading this book will also help you to get all of the
benefits from your water softener.
▲ Your water softener will remove hardness minerals
and “clear water” iron from water, up to the limits
shown on page 4-1. It will not remove other types of
iron, acids, tastes and odors, etc. It will not purify pol
luted water or make it safe to drink.
▲ Protect the softener and piping from freezing. Dam
age from freezing voids the softener warranty. See
page 3-3.
PLEASE READ AND COMPLY WITH THE FOLLOWING
GUIDES TO PREVENT DAMAGE TO THE SOFTENER
OR OTHER PROPERTY, PERSONAL INJURY, OR POS
SIBLE FATAL SHOCK.
▲ THIS SOFTENER WORKS ON 24 VOLTS ONLY. BE
SURETO USE ONLY THE TRANSFORMER INCLUDED,
AND PLUG IT INTO A HOUSEHOLD 120V OUTLET. IF
TRANSFORMER IS REPLACED, USE ONLY THE AU
THORIZED SERVICE, CLASS II, 24 VOLT, 10 VA
TRANSFORMER.
▲ Unplug the transformer right away if the power
cable should become damaged or frayed. Make re
pairs before plugging back into the power outlet.
▲ Always unplug the softener from electrical power
before removing outer valve covers.
▲ This system is not intended to be used for treating
water that is microbiologically unsafe or of unknown
quality without adequate disinfection before or after
the system.
To be sure you have done all the steps to install the
softener, read the followinglist. Refer to the Installa
tion Manual, part no. 7231741, for step-by-step
guides.
Page numbers referred to are in the Installation
Manual unless otherwise noted.
Is the house water flow going INTO the softener
valve INLET? Trace piping to be sure. See pages
2- 4 and 2-5.
Is the plumbing bypass valve (or 3 valves) set for
SERVICE? Bypass valve(s) should always re
main in soft water service position. Position in
"bypass" only if needed for softener repairs. See
FIG. 14, page 4-1 of this manual.
p^ Is the valve drain hose connected the right way,
and without sharp bends or kinks that could
stop or reduce water flow? See page 3-5 in the
installation manual.

Care is taken at the factory to keep your water soft
ener 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.
The first time you sanitize your softener, be sure
to doa/l steps in the installation manual, and on
pages 1-2, 1-3 and 1-4 of this manual first.
Lift the salt hole cover and use a pail to fill the
salt storage tank with up to 3 gallons of water.
Remove the brinewell cover (FIG. 3) and pour
about 3/4 ounce, or 1 to 2 tablespoons, of com
mon 5.25%, miscented, household bleach (Clorox, Linco, BoPeep, White Sail, Eagle, etc.) in the
softener brinewell. Replace the brinewell cover.
Press the ON/OFF-HOLD button and hold for 3
seconds to start a recharge. This first recharge
does several things.
FIG.3
• 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 prepares the resin bed (see page 2-4) for ser
vice.
Notes:
This recharge takes about 2-1/2 or2-3/4 hours, de
pending on the salt type setting (page 1-4).
You can sanitize the softener with or without salt
in the storage tank.
(J)
Recommended by the Water Quality Association. On some
water supplies, the water softener may need periodic
disinfecting.
Brine (salt dissolved in water) is needed for each and
every regeneration. The water for making brine is me
tered into the salt storage tank by the softener. Howev
er; you must keep salt in the tank^ but it is not necessary
to keep it full. In humid areas, it is best to fill the stor
age tank one quarter to one half full, and to refill it
more often. Salt bridging (see page 3-1) occurs more
WATER SOFTENING SALT WITH IRON REMOVING
ADDITIVES — Some salts have an additive to help the
softener handle iron in the water supply. These salts
may be used if your water supply has a high iron con
tent. It is recommended to use Sears Resin Bed Clean
er 42- 34426, for periodic treatments to keep your resin
bed clean.
often when conditions are humid.
Fill the tank with NUGGET or ppppET water softener
salt. DO NOT use rock salts, as they have dirt and sedi
ments 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 4-1. Be sure to set the salt monitor system
(see page 2-1).
Note: The salt monitor system, page 2-1, 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.
If you choose Potassium Chloride (KCl) as a regener
ant, following these suggestions will help give you
years of maintenance free service.
1) Place only one bag of KCl in your softener at a time
(the salt storage tank should contain no more than 60
pounds of KCl at any one time).
2) A softener using KCl should not be placed in areas
with temperature fluctuations and high humidity
(KCl will harden in these environments and may
make the softener inoperable).
3) Check the brine tank and brine well (black tube in
salt storage tank) monthly. If hardening is present,
pour small amounts of warm water on hardened areas
until they loosen.
4) If your softener does not have a KCl salt setting you
must increase your hardness setting by 25% to ensure
continuous soft water as in example below.

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 so
dium intake. For example, if your water supply is 15
grains hard, you would have to drink 3 quarts of soft
ened water to consume 335 milligrams of sodium.
That is equivalent to eating2-l /2 slices of white bread.
Persons who are concerned about their drinking water
should consider a Kenmore Drinking Water System
that will remove or reduce in excess of 90% of the so
dium and other drinking water contaminants.
You have now finished the water softener start up. After the sanitizing recharge, on page 1-5, the soft
ener will be giving you soft water. Please read pages 2 - 4,2 - 5 and 2 - 6 in section 2 to understand how
the softener works to continue to give you soft water.

Sometimes, a manually started

^ 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:
Lift the salt hole cover and level the salt in the
storage tank.
The salt level decal, on the brinewell inside the
tank, has numbers from 0 to 8 (see drawing be
low). Observe the number the leveled salt is at
or closest to.
Now, press the SALT LEVEL ADJUST button
until black bars display up to the salt level num
ber. For example, the pictures below show the
salt level at 6.
Finally, set the level you want the low salt indi
cator light to come on. Press the SIGNAL LIGHT
ADJUST button until a (^) shows opposite this
number. In the example below, the light will
come on 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 (see note on page 1-6).
If you wish to turn the salt monitor off, press the
SIGNAL LIGHT ADJUST button until OFF
shows above.
Note:
For accurate salt monitor operation, always use
nugget or pellet water softener salt. See page 1-6.

operating efficiency, and under most conditions this
feature will be left in its default mode. However,
you can modify this feature if you want to force a
