1A. SAFETY GUIDES
WATER SOFTENER START-UP
A 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 dam
age. Reading this book will also help you to get all of
the benefits from your water softener.
A Your water softener will remove hardness miner
als and “clear water” iron from water, up to the limits
shown on page 19. It will not remove other types of
iron, acids, tastes and odors, etc. It will not purify
polluted water or make it safe to drink.
A Protect the softener and piping from freezing.
Damage from freezing voids the softener warranty.
See page 17.
CAUTIONS
PLEASE READ AND COMPLY WITH THE FOLLOW
ING GUIDES TO PREVENT DAMAGE TO THE SOFT
ENER OR OTHER PROPERTY, PERSONAL INJURY,
OR POSSIBLE FATAL SHOCK.
A THIS SOFTENER WORKS ON 24 VOLTS ONLY. BE
SURE TO USE THE TRANSFORMER INCLUDED,
AND PLUG IT INTO A 120V OUTLET.
A Unplug the transformer right away if the power
cable sould become damaged or frayed. Make re
pairs before plugging back into the power outlet.
A Always unplug the softener from electrical power
before removing outer valve covers.
SECTION 1
1B. CHECK LIST OF ALL STEP-BY-STEP GUIDES TO INSTALL
To be sure you have done all the steps to install the
softener, read the following list. Refer to the
Installation Manual, part no. 7183613, 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
10 and 11.
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. 12, page 19 of this manual.
WATER SOFTENER START-UP
✓ Is the valve drain hose connected the right way,
and without sharp bends or kinks that could
stop or reduce water flow? See page 16.
Page numbers referred to are in the Installation
Manual unless otherwise noted.
✓ Is the softener power cable connected to the
transformer? Is the transformer plugged into an
inside, 120V-60HZ electrical outlet? See page 20
in the installation manual, and the wiring sche

it by adding to the water hardness number. For
exanrple, assume your water is 20 gpghard and contains
2 ppm iron. Add 5 to the hardness number for each 1
ppm of iron. In this example, you would use 30 for your

first, proceeding the normal re
generation sequence (see page
12). This provides extra clean

regenerated with the salt brine. To conserve water,
if your water supply does not contain iron or
sediments, be sure this feature is set to OFF. Use the

1D. SANITIZING THE WATER SOFTENER
WATER SOFTENER START-UP
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, instal
ling 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 (FIG. 3) and pour
about 3/4 ounce, or 1 to 2 tablespoons, of
common
co, BoPeep, White Sail, Eagle, etc.) in the
softener brinewell.
4. Press the ON/OFF-HOLD button and hold for 3
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 need
ed.
— It gets all the air out of the resin tank.
— It prepares the resin bed (see page 12) for
service.
NOTES:
This recharge takes about 2-1/2 or 2-3/4 hours,
depending on the salt type setting (page 7).
You can sanitize the softener with or without
salt in the storage tank.

Recommended by the Water Quality Association. On
some water supplies, the water softener may need pe
riodic disinfecting.

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 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 20.
system (see page 10).
NOTES:
The salt monitor system, page 10, 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.
In humid areas, it is best to fill the storage tank
half-full, and to refill it more often. Salt bridging
(see page 15) occurs more often when conditions
are humid.
WATER SOFTENING SALT WITH IRON REMOV
ING 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.
Be sure to set the salt monitor
FIG.3
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.
ADD SALT

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 sodium and other drinking water contami
nants.
You have now finished the water softener start up. After the sanitizing recharge, on
page 8, the softener will be giving you soft water.

HOW YOUR WATER SOFTENER WORKS
EXTRA RECHARGE
Sometimes, a manually started regeneration (re
charge) 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.

indicator light to remind you to refill the storage
tank with salt. To set this monitor system:
1. Lift the salt hole cover and level the salt in the
storage tank.
2. The salt level decal, on the brinewell inside the
tank, has numbers from 0 to 8 (see drawing on
page 9 and below). Observe the number the
leveled salt is at or closest to.
3. Now, press the SALT LEVEL ADJUST button
until black bars display up to the salt level
number. For example, the pictures below show
the salt level at 6.
4. Finally, set the level you want the low salt
indicator light to come on. Press the SIGNAL
LIGHT ADJUST button until a (Y) shows
opposite this number. In the example below,
the light will come one 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. To turn the
salt monitor off, press the SIGNAL LIGHT
ADJUST button until OFF shows above.

If the CLEAN feature is set to ON, a cleaning
