System Operation

Treated Water (Downflow)
Untreated water is conditioned as it flows through the
resin bed and up the riser. The 269 upflow conditioner
is a system that will refill the salt tank at the start of a
regeneration cycle. When a regeneration cycle
begins, the salt tank is filled and brine is allowed to
develop before Cycle 1 starts
Regenerant Refill – Cycle C8
Water is directed to the regenerant tank to create
regenerant for the next regeneration.
Backwash (Upflow) – Cycle C1
Flow is reversed by the control valve, directed down
the riser, up through the resin bed and sent to drain.
The bed is expanded and debris is flushed to the
drain.
Regenerant Draw (Downflow) – Cycle C2
Water passes through the injector and regenerant is
drawn from the regenerant tank. The regenerant is
directed to the resin bed. The hardness ions are
displaced by sodium ions. Regenerant draw is
completed when the air check closes.

Slow Rinse (Downflow) – Cycle C3
Water flow moves the regenerant through the resin
at a specific rate and rinses to the drain. The resin is
regenerated.
Repressurization – Cycle C4
Pressure is balanced in the valve before continuing
the regeneration.
Fast Rinse (Downflow) - Cycle C5
Water passes through the resin bed and up through
the riser to drain. All remaining regenerant residual is
rinsed from the resin bed.
nd
2 Backwash (Upflow) – Cycle C6
Flow is identical to C1 Backwash. The resin is
reclassified.
nd
2 Rinse (Downflow) - Cycle C7
Flow is identical to C5 Fast Rinse. The resin bed is
rinsed to quality.
