Premier AF-40K - System Recharge Cycles (9-Cycle Operation)

System Recharge Cycles (9-Cycle Operation)
Service (Downow):
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 Rell:
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 rell cycle lls the salt tank with water, this cycle
allows time for the salt to dissolve into the water.
3. Backwash 1 (Upow):
The ow 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 ushed to the drain.
4. Brine Draw (Downow):
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.
5. Slow Rinse (Downow):
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.
6. Repressurize Cycle (Hard Water Bypass Flapper Open):
This cycle closes the appers for a short time to allow the
air and water to hydraulically balance in the valve before
continuing the recharge.
7. Fast Rinse 1 (Downow):
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.
8. Backwash 2 (Upow):
The ow 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 ushed to the drain.
9. Fast Rinse 2 (Downow):
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.
