Charts

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.

• Refer to “Refrigeration System Diagnostics” for the

data that must be collected. This list includes:

before beginning service, ice production check,

installation/visual inspection, water system

checklist, safeguards, discharge and suction

pressure analysis.

• 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.

• Zero out manifold gauge set before obtaining

pressure readings to avoid misdiagnosis.

• Discharge and suction pressure are highest at the

beginning of the cycle. Allow system to stabilize,

then verify the pressures are within the range

indicated.

• All pressure readings must be obtained at the ice

machine head section. Lineset length will affect

pressures at the condensing unit.

• Water temperature will affect suction and

discharge pressure - 50° water temperature will

result in pressures on the lower end of the ranges

specified. 90° water temperatures will result in

pressures on the upper end of the ranges

specified.
