ANALYZING DISCHARGE PRESSURE
1. Determine the ice machine operating conditions:
Air temperature entering condenser ______
Air temperature around ice machine ______
Water temperature entering sump trough ______
2. Refer to “Installation/Visual Inspection Checklist” on
page 100 for ice machine being checked.
Use the operating conditions determined in step 1 to find
the published normal discharge pressures.
Freeze Cycle ______
Harvest Cycle ______
3. Perform an actual discharge pressure check.
Freeze Cycle

Harvest Cycle
PSIG
Beginning of
Cycle __________ __________
Middle of
Cycle __________ __________
End of
Cycle __________ __________
4. Compare the actual discharge pressure (Step 3) with
the published discharge pressure (Step 2).
The discharge pressure is normal when the actual
pressure falls within the published pressure range for the
ice machine’s operating conditions. It is normal for the
discharge pressure to be higher at the beginning of the
freeze cycle (when load is greatest), then drops throughout
the freeze cycle.
