INSULATION REQUIREMENTS
To prevent condensation, the entire suction line
including the shut-off valve must be insulated. All
insulation must be airtight and sealed at both ends.
The following insulation requirements prevent
condensation at 90°F (32.2°C) ambient 90% Relative
Humidity. If higher humidity is expected, increase
insulation thickness.
The entire suction line set, including the suction service
valve located on the back of the ice machine, requires:

To prevent condensation the entire suction line
including the shut off valve must be insulated. All
insulation must be airtight and sealed at both ends.
The minimum requirements are for conditions at or
below 90% humidity and 90°F (32.2°C) ambient.
When higher humidity will be experienced, insulation
wall thickness will need to be increased.
