SYSTEM RECHARGE CYCLES

9-CYCLE OPERATION

Service (Downflow):
Untreated water is directed down through the
resin bed and up through the riser tube. The
hardness ions attach themselves to the resin
and are removed from the water. The water is
conditioned as it passes through the resin bed.
1. Brine Refill:
Water is directed to the salt tank at a
controlled rate, to create brine for the next
recharge.
2. Brine Prep (Dissolve Salt)
After the refill cycle fills the salt tank with
water, this cycle allows time for the salt to
dissolve into the water.
3. Backwash 1 (Upflow):
The flow of water is reversed by the control
valve and directed down the riser tube
and up through the resin bed. During the
backwash cycle, the bed is expanded and
debris is flushed to the drain.
4. Brine Draw (Downflow):
The brine draw cycle takes place during
the slow rinse cycle. The control directs
water through the brine injector and brine
is drawn from the salt tank. Brine draw is
completed when the air check in the salt
tank closes.

Slow Rinse (Downflow):
The brine is directed down through the
resin bed and up through the riser tube to
the drain. The hardness ions are displaced
by sodium ions and are sent to the drain.
The resin is recharged during the brine
cycle.
Repressurize Cycle (Hard Water Bypass
Flapper Open):
This cycle closes the flappers for a
short time to allow the air and water to
hydraulically balance in the valve before
continuing the recharge.
Fast Rinse 1 (Downflow):
The control directs water down through the
resin bed and up through the riser tube to
the drain. Any remaining brine residual is
rinsed from the resin bed.
Backwash 2 (Upflow):
The flow of water is reversed by the control
valve and directed down the riser tube
and up through the resin bed. During the
backwash cycle, the bed is expanded and
debris is flushed to the drain.
Fast Rinse 2 (Downflow):
The control directs water down through the
resin bed and up through the riser tube to
the drain. Any remaining brine residual is
rinsed from the resin bed.
