2B. SOFT WATER SERVlCE AND REGENERATION

SERVICE
When the softener is giving you soft water, it is
called "Service"° During service, hard water flows
through 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. 4)_ As hard water passes through the bed,
each bead attracts and holds the hardness miner-
als. This is called ion_exchanging. It is much like a
magnet attracting and holding metals_ Water with-
out the hardness 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 regeneration or
recharge. Regeneration is started at 2:00 a.m. by the
electronic timer (see page t4)o It takes place in 5
stages or cycles° These are:
E] FILL [] BACKWASH
[_ BRINING [_ FAST RINSE
BRINE RINSE
NOTE:
If the CLEAN feature (page 7) is set to ON,
additional backwash and fast rinse cycles occur
before the fill cycle.

REGENERATION
[] FILL: Salt, dissolved in water, is called brine.
Brine is needed to clean the hardness rninerals
from the resin beads, To make the brine, water
flows into the salt storage area during the fill stage
as shown in FIG. 5. Fill cycle length depends on
how much soft water making capacity you have
used since the last regeneration. As you use more
water, fill time increases so more brine is made. The
greater amount of brine cleans more hardness
minerals from the resin bed,
