ANALYZING DISCHARGE LINE TEMPERATURE
1. Determine the ice machine operating conditions:
Air temp. entering condenser ______
Air temp. around ice machine ______
Water temp. entering sump trough ______
2. Refer to “Cycle Times, 24 Hr. Ice Production and
Refrigerant Temperature Charts” on page 101 for
ice machine being checked.
Use the operating conditions determined in step 1 to
find the published normal discharge temperatures.
Freeze Cycle ______
Harvest Cycle ______
3. Perform an actual discharge temperature check.
4. Compare the actual discharge temperature
(step 3) with the published discharge temperature
(step 2).
The discharge temperature is normal when the actual
temperature falls within the published temperature
range for the ice machine’s operating conditions. It is
normal for the discharge temperature to be higher at
the beginning of the freeze cycle (when load is
greatest), then drop through out the freeze cycle.
