Hard, unfiltered water enters the valve inlet port. Internal valve
porting routes the water down and out the top distributor, into the
mineral tank. The water is filtered as it passes through the
mineral bed, then enters the bottom distributor. Filtered water
llows back into the valve and out the valve outlet, to the house
filtered water pipes.

Timer/switch action allows the motor to turn the rotor & disc
to place the valve in BACKWASH. Water is routed down and
out the bottom distributor, upthrough 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, and iron deposits
to the drain.
During FAST RINSE, the rotor & disc is positioned so water
flow enters the mineral tank through the top distributor, and
exits through the bottom distributor, tothe drain. The fast flow
of water downward through the mineral bed flushes any re-
maining sediments to the drain. The mineral bed is packed and
prepared for return to service.
The solid state timer again energizes the motor to return the
valve to service. As the valve rotates, the position switch lever
drops to open the circuit. The valve remains positioned in ser-
vice until the timer initiates the next regeneration.
