Analyzing Discharge Pressure in the Freeze Cycle
1. Determine the ice machine operating conditions:
Air temp. entering condenser ______ °
Water temp. entering sump trough ______ °
2. Refer to Operating Pressure table (starting on page
201) for ice machine being checked.
3. Use the operating conditions determined in step
1 to find the published normal discharge pressures:
Freeze Cycle ______
Harvest Cycle ______
4. Perform an actual discharge pressure check.
Freeze Cycle
psig (kPa)
1 Minute into the
Freeze Cycle __________
Middle of Freeze Cycle __________
End of Freeze Cycle __________
5. 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 drop throughout the Freeze cycle.
