ANALYZING SUCTION PRESSURE
The suction pressure gradually drops throughout the
freeze cycle. The actual suction pressure (and drop rate)
changes as the air and water temperature entering the
ice machine changes. These variables also determine the
freeze cycle times.
To analyze and identify the proper suction pressure drop
throughout the freeze cycle, compare the published
suction pressure to the published freeze cycle time.
NOTE: Analyze discharge pressure before analyzing suction
pressure. High or low discharge pressure may be causing
high or low suction pressure.
