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.
