Cycle Times, 24 Hr. Ice Production and
Refrigerant Temperature Charts
These charts are used as guidelines to verify correct
ice machine operation.
Accurate collection of data is essential to obtain the
correct diagnosis.
• Beginning temperatures are taken 1 minute after
the water pump energizes.
• Refer to "Operational Analysis Chart" for the list of
data that must be collected for refrigeration
diagnostics.
• Ice production checks that are within 10% of the
chart are considered normal. This is due to
variances in water and air temperature. Actual
temperatures will seldom match the chart exactly.
• Suction temperature is highest at the beginning of
the cycle. Suction temperature will drop throughout
the cycle. Verify the temperatures are within the
range indicated.
