6. Service
When the Solitaire valve is in service, the inlet/by-pass valve is open to the
inlet position and the outlet valve is open. The control, safety and drain
valves are closed. Hard water flows down the central distributor tube and
up through the resin bed.
7. Control Flow
When the set point volume has metered through the Solitaire valve
(determined by the hardness setting on the AccuDial), the control valve
opens to drive a regeneration.
8. Open By-pass / Close Inlet
In the first step in a regeneration, the inlet/by-pass valve shifts to the
by-pass position to allow hard water to by-pass the softener while it is in
regeneration.
9. Isolate
During the isolation step, the outlet valve closes.
