Location of Ice Machine
The location selected for the ice machine must meet the
following criteria. If any of these criteria are not met, select
another location.
• The location must be free of airborne and other
contaminants.
• The air temperature must be at least 45°F (7°C), but must
not exceed 110°F (43°C).
• The water temperature must be at least 45°F (7°C), but
must not exceed 90°F (32°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 and allow the ice
machine to be level front to back and side to side.
• The location must allow enough clearance for water and
electrical connections in the rear of the ice machine. The
drain can be routed out the rear or bottom of dispenser.
• The location must not obstruct airflow through or around
the ice machine. Airflow is in the left side and out the
top. Refer to chart for clearance requirements.
These ice machines are intended for use in household and
similar applications such as:
• Staff kitchen areas in shops, offices and other work
environments.
• Clients in hotels, motels, farmhouses, bed and breakfast
and other residential type environments.
• Catering and similar non-retail applications.
Ice Machine Clearance Requirements
CNF201 CNF202
Top 24" (61 cm) 24" (61 cm)
Sides 8" (20 cm) 8" (20 cm)
Back* 5" (13 cm) 5" (13 cm)
* 5" (13 cm) is recommended for servicing the ice machine. Clearance can
be 0" when water and drain connections exit the bottom of the ice machine.
Notice
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”.
SEALING TO COUNTERTOP OR STAND
Ice machines installed without legs must be sealed to the
countertop or stand. This prevent liquids or debris from
infiltrating beneath the ice machine.
Caution
,
To avoid instability the ice machine must be installed in an
area capable of supporting the weight of the ice machine
and a full bin of ice.
