SECTION 2 .ow YOUR WATER SOFTENER WORKS

2B. SOFT WATER SERVICE, AND REGENERATION
SERVICE
When the softener is giving you soft water, it is called
"Service" During service, hard water comes from
the house main water pipe into the softener. Inside
the softener resin tank is a bed made up of
thousands of tiny, plastic resin beads (FIG. 7 ). As
hard water passes through the bed, each bead
attracts and holds the hardness minerals This is
called ion-exchanging. It is much like a magnet at-
tracting and holding metals. Water without the hard-
ness minerals (soft water) flows out of the softener
and into the house soft water pipes.
After a period of time, the resin beads become coated
with hardness minerals and they have to be cleaned
This cleaning is called recharge, or regeneration.
Regeneration is started at about 2:00 a.m. (factory
setting) by the timer It takes place in 5 stages or
cyctes. These are:
[] FILL [] BACKWASH
[] BRINING [] FAST RINSE
[] BRINE RINSE

[] FILL: Salt, dissolved in water, is called brine.
Brine is needed to clean the hardness minerals from
the resin beads. To make the brine, soft water flows
into the salt storage area during the fill cycle as
shown in FIG 8.
The length of the fill cycle is factory set to provide
softening capacity for an average family. You can
reset this time when "fine4uning" the water softener,
