ANALYZING DISCHARGE PRESSURE

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-Hour Ice Production/

Refrigeration Pressure Chart 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.

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 drop throughout the Freeze cycle.
