WATER FLOW THROUGH THE SOFTENER VALVE
SERVICE CYCLE
Hard water enters the valve inlet port. Internal
valve porting routes the water down and out the
top distributor, into the resin tank. Hard water is
softened as it passes through the resin bed, then
enters the bottom distributor. Soft water flows back
into the valve and out the valve outlet, to the
house soft water pipes.

FILL CYCLE
To begin a regeneration, the electronic timer ener-
gizes the circuit to the valve motor. The valve
motor rotates the rotor and disc and the valve cam
until the position switch lever drops, to open the
motor circuit and position the valve in FILL. As the
rotor and disc rotates, the port opens for SOFT
water fin through the venturi. Fill flow continues to
the brine valve, and into the salt storage tank. Soft
water is still available to the house lines.in.

BRINING AND BRINE RINSE CYCLES
After fill, timer/switch action allows the motor to
turn the rotor and disc into BRINING position.
Water flow is directed to the nozzle. Suction, creat-
ed by the nozzle and venturi, draws brine from the
salt storage tank and injects it into the resin bed
via the bottom distributor. Flow continues out the
top distributor and to the drain. Hard water is avail- BypassHard
able at the valve outlet. WaterTo

When the brine valve closes to end brine draw,
water flow continues in the same directions to
