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, created 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 available at the valve outlet.

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

directions to slowly RINSE brine from the resin bed and to the drain.

Timer/switch action again allows the motor to turn the rotor & disc to place the valve in BACKWASH,

stopping water flow to the nozzle. Water is routed

down and out the bottom distributor, up through the

bed, and out the top distributor to the drain. The fast

flow (controlled by a flow plug in the drain fitting)

flushes dirt, sediments, iron deposits, remaining brine

and hardness to the drain.
