••
PSIG
Typical Discharge Pressure, In Harvest:
••
PSIG
High Pressure Cut Out
••
Cuts out at 380 PSIG, resets at 315 PSIG
Thermostatic Expansion Valve
••
Superheat is 3

F.
Ice Size Thermostat:
••
Switches to harvest cycle with temperature fall to 38
o
F.. Resets at 43
o
F.
Ice Size Heater
••
Adds heat to ice size thermostat to prevent premature harvest. 6,000 ohms resistance.
Harvest Termination Thermodisk
••
Switches from contacts C-NC to contacts C-NO at a temperature rise to 55
o
F. At that point the
machine returns to the Freeze Cycle or switches OFF. The thermodisk resets at 40
