Analyzing Suction Pressure - Koolaire KY0275W Technician's Handbook

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.
