S
• 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.
C
T
• 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 polluted water or make it safe to drink.
• Protect the softener and piping from freezing. Damage from freezing voids the softener warranty.

These salts may be used if your water supply has a

It is recommended
to use Sears

to keep your resin bed clean.
This is available
at
your local Sears store.
You must keep salt in the tank, but because the water softener
is very efficient, it is not necessary
to
keep it full. Especially
in humid areas, it is best to

3) Check the brine tank and brine well (black tube in

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. 10. Make a pencil mark on
the handle, 1" or 2" below the top height of the rim.
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
