Location of Ice Machine
A Manitowoc ice machine operates most efficiently
when it is:
1. Located Away From Heat Sources
Do not install the ice machine near heat-
generating equipment or in an area of direct
sunlight.
Air Temperature Around Ice Machine
Minimum Maximum
35°F (1.7°C) 110°F (43.3°C)
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
“Winterization” in the Owner/Operator Use and
Care Guide.
2. Located in a Contaminant-Free Area
Airborne contaminants can damage ice machines.
Air-cooled models are particularly vulnerable.
3. Provided with Sufficient Air Clearance
Adequate airflow through and around the ice
machine is essential for maximum ice production
and long component life.
Air Clearance Around Ice Machine
Model Area Clearance
Self-Contained Top 8” (20 cm)
Air-Cooled Sides 8” (20 cm)
Back 5” (12 cm)
Water-Cooled Top
or Remote Sides 5” (12 cm)

This clearance is not required, but it is recommended
for efficient operation and servicing.
Important
Two stacked ice machines may share a single ice
storage bin. A stacking kit is required for stacking
two ice machines. Follow the instructions supplied
with the stacking kit.
Heat of Rejection
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 you are sizing air conditioning
equipment for the ice machine installation area.
This information is also necessary when evaluating
the benefits of using water-cooled or remote
condensers to reduce air conditioning loads. The
amount of heat added to an air conditioned
environment by an ice machine with a water-cooled
or remote condenser is negligible.
Knowing the amount of heat rejected is also
important when sizing a cooling tower for a water-
cooled condensing unit. The peak figure is used for
sizing the cooling tower.

Because the heat of rejection varies during the ice
making cycle, the figure shown is an average.
