Charts

Cycle Times, 24 Hr. Ice Production and

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.

• Production and cycle times are for dice cube - Half

dice cube cycle times can be 1-2 minutes faster

depending on model and ambient temperature.

• 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.

• Regular cube production derate is 7%.

• 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.

• Record beginning of freeze cycle suction pressure

one minute after the water pump energizes.

• 50Hz dice and half dice production derate is 12%.

• 50HZ regular cube production derate is 14%.
