ANALYZING SUCTION TEMPERATURE
The suction temperature gradually drops throughout
the freeze cycle. The actual suction temperature (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 temperature
drop throughout the freeze cycle, compare the
published suction temperature to the published freeze
cycle time.
NOTE: Analyze discharge temperature before
analyzing suction temperature. High or low discharge
temperature may be causing high or low suction
temperature.
