Eliminates the need for additional solenoid valves. (4 way) In the de-energized position, the discharge gas is routed through the main condenser and the auxiliary condenser is pumped out to suction. (3 way) In the energized position, discharge gas is fed through the valve and into the auxiliary condenser. The pump out line is automatically closed. This diagram is a typical heat reclaim configuration.
