SECTION 1
WATER SOFTENER START-UP
1E.
FILL THE STORAGE TANK WITH SALT
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. Be sure to set the salt monitor 
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.

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.
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.
