Cycle Times/24-Hour Ice Production/
Refrigerant Pressure Charts
These charts are used as guidelines to verify correct ice
machine operation.
Accurate collection of data is essential to obtain the
correct diagnosis.
Exclude all non-refrigeration issues before diagnosing
the refrigeration system.
Visually inspect the clearances, drains, condensers/
filters for dirt and replace the water filter.
Verify that the water flow is uniform throughout the
evaporator.
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.
Refer to “Operational Analysis Chart” for the list
of data that must be collected for refrigeration
diagnostics.
Zero out manifold gauge set before obtaining pressure
readings to avoid mis-diagnosis.
Discharge and suction pressure are highest at the
beginning of the cycle. Suction pressure will drop
throughout the cycle. Verify the pressures are within
the range indicated.
