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.
• 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.
