Harvest Cycle:

During the harvest cycle, the refrigerant flows from
the condenser, through the discharge line to a
branch in the line containing the Hot Gas Valve.
This valve is Open during the harvest cycle,
allowing the hot discharge gas to bypass the
condenser and enter the evaporator at its inlet.
The hot discharge gases warm up the evaporator
enough to allow the surface of the ice frozen to the
evaporator to melt. The remaining ice will then fall
off into the bin.
