Harvest Sequence

The air compressor (when used) and the harvest
valve(s) open at the beginning of the water purge to
divert hot refrigerant gas into the evaporator.
The water pump continues to run, and the water dump
valve energizes to purge the water in the water trough.
Single evaporator models energize the water fill valve
for the last 15 seconds of the water purge cycle.
