HOW YOUR WATER SOFTENER WORKS
I
ed. This cleaning is called regeneration or recharge
Regeneration is started at 2:00 a.m by the electronic
timer (See page 16)It takes place in 5 stages or
cycles. These are:
[-_ FILL I_] BACKWASH
[2] BRINING [] FAST RINSE
I-'3-] BRINE RINSE
REGENERATION
[_ FILL: Salt, dissolved in water, is called brine.
Brine is needed to clean the hardness minerals from
the resin beads_ To make the brine, water flows into
the salt storage area during the fill stage as shown in
FIGo 21. The fill cycle lasts from 9 to 21 minutes,
depending on how much soft water making capacity
you have used since the last regeneration° It fills
longer, the more water you have used, and makes
more brine The greater amount of brine cleans more
hardness minerals from the resin bed (see below).

[] BRINING: During brining, the brine is taken from
the salt storage tank and put into the resin tank° Brine
makes the resin beads let go of the hardness
minerals and they are carried to the drain. How much
brine is needed to clean the resin depends on 2
things--
The amount of resin in the softener
How fast the brine goes through the bed_
The nozzle and venturi (FIG 22) make suction to take
brine from the salt tank and put it into the resin tank.
They keep the brine flow down to a very slow rate
to get the best resin cleaning with the least salt.
[] !BRINE RINSE: After all of the brine goes into the
resin tank, the brine valve closes, Water keeps flow-
ing the same way it did during brining except the brine
flow has stopped. Hardness minerals and brine flush
from the resin tank to the drain Brining and brine
rinse together vary in length, from 47 to 71 minutes,
relative to fill cycle length.
