SAFETY GUIDES

• 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 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.
• Protect the softener and piping from freezing.
Damage from freezing voids the softener warranty.
See page 17.

SANITIZING

THE WATER SOFTENER

ADD WATER

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.

WATER SOFTENING SALT WITH IRON REMOVING ADDITIVES -- Some salts have an additive to

Although
this additive

softener parts.

During

SALT BRIDGE

Sometimes,
a hard crust or salt bridge forms in the

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

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.

pencil
mark

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. 9. 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
