• The location must be free of airborne and other
contaminants.
• The air temperature must be at least 35°F (1.6°C),
but must not exceed 110°F (43.4°C).
• The location must not be near heat-generating
equipment or in direct sunlight.
• The location must be capable of supporting the
weight of the ice machine and a full bin of ice.
• The location must allow enough clearance for
water, drain and electrical connections in the rear
of the ice machine.

* B.T.U./Hour
** Because the heat of rejection varies during the ice making
cycle, the figure shown is an average.
Ice machines, like other refrigeration equipment,
reject heat through the condenser. It is helpful to
know the amount of heat rejected by the ice machine
when sizing air conditioning equipment where selfcontained air-cooled ice machines are installed.
NOTE: The ice machine may be built into a cabinet.
There is no minimum clearance requirement for the
top or left and right sides of the ice machine. The
listed values are recommended for efficient operation
and servicing only.
CAUTION
The ice machine must be protected if it will be
subjected to temperatures below 32°F (0°C).
Failure caused by exposure to freezing
temperatures is not covered by the warranty.
See “Removal from Service/Winterization” on page
4-10.
