5. Discharge line temperature is greater than 150°F
(66°C) [22" Models Only - 140°F (60°C)] at the end of
the freeze cycle?
See “Discharge Line Temperature Analysis” on
.
6. Connect refrigeration manifold gauge set to the
access valves on the front of the ice machine.
Establish baseline by recording suction and discharge
pressure and freeze & harvest cycle times. (Refer to
“Cycle Times/24-Hour Ice Production/Refrigerant
Pressure Charts” on page 201 for data collection
detail.)
7. Freeze cycle Head Pressure is in the range indicated in
the cycle time/24 hour ice production and operational
pressure chart?
If the head pressure is low refer to “Freeze Cycle
.
8. Freeze cycle Suction Pressure normal?
Refer to if
suction pressure is high or low.
9. Harvest cycle suction and discharge pressures are
lower than indicated in the cycle times/refrigerant
pressures/24 hour ice production chart?
Replace Harvest Pressure Regulating solenoid.
