Ice Production & Refrigerant Pressure
These charts are used as guidelines to verify correct ice
machine operation.
Accurate collection of data is essential to obtain the
correct diagnosis.
• 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 for a
minimum of 10 minutes, then verify the pressures are
within the range indicated.
• Water temperature will affect suction and discharge
pressure - 50°F (10°C) water temperature will result in
pressures on the lower end of the ranges specified.
90°F (32°C) water temperatures will result in pressures
on the upper end of the range specified.
