Introduction
The 255 series control incorporates five cycles during operation, Figure 3 and is
responsible for directing the flow of water during all phases of regeneration. The
water conditioner consists of a control valve, mineral tank, resin and a salt storage
tank. During the service cycle, hardness contaminants are removed from the
water by the resin bed. The regeneration process consists of backwash, brine and
slow rinse, fast rinse and brine refill cycles. During the regeneration process the
hardness contaminants are removed from the resin bed and flushed to the drain,
while the resin bed is regenerated with brine. A description of each cycle and its
function is listed below:

1. 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.

2. Backwash (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.

3. Brine/Slow Rinse (Downflow):
The control directs water through the brine injector and brine is drawn from
the salt tank. The brine is then 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 regenerated during the
brine cycle. Brine draw is completed when the air check closes.

5. Brine Refill (Downflow):
Brine refill occurs during a portion of the fast rinse cycle. Water is directed to
the salt tank at a controlled rate, to create brine for the next regeneration.
