Brining; Brine Rinse; Backwash - Kenmore IntelliSoft 350 Series Owner's Manual

SOFT WATER SERVICE AND REGENERATION
BRINING: During brining, the brine is moved from the
salt storage area, into the resin tank. See Fig. 43.
Inside the resin tank, brine cleans hardness minerals
from the resin beads and they are discharged out the
drain. How much brine is needed to clean the resin
depends on:
• The amount of water used between regenerations.
• The amount of resin in the softener,
• How fast the brine goes through the bed.
The nozzle and venturi makes 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 is moved into the
resin tank, the brine valve closes. Water keeps flowing
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 the length of time they take, relative to
the fill cycle length. See Fig. 43.
BACKWASH: During backwash, water flows UP
through the resin tank at a fast rate to flush iron miner-
als, dirt and sediments from the bed and to the drain.
The bed lifts and expands for good cleaning. See Fig.
44.
