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 indoors.
• 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.
• The location must allow enough clearance for
water, drain and electrical connections in the rear
of the ice machine.
• The location must not obstruct airflow through or
around the ice machine. Refer to the chart below
for clearance requirements.
• RFC Condensing Units ONLY - Interconnecting
wiring (115/60/1 or 230/50/1) is required between
the ice machine and condensing unit to energize
the contactor coil.
• 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

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
sizing air conditioning equipment where self-contained
air-cooled ice machines are installed.
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 using 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
condenser. Use the peak figure for sizing the cooling
tower.

The location selected for the Remote Units must meet
the following criteria. If any of these criteria are not

• The air temperature must be at least -20°F
(-28.9°C) but must not exceed 120°F (49°C).
• The location must not allow exhaust fan heat and/
or grease to enter the condenser.
• The location must not obstruct airflow through or
around the condensing unit. Refer to the chart
below for clearance requirements.
• RFC Condensing Units ONLY - Interconnecting
wiring (115/60/1) is required between the ice
machine and condensing unit to energize the

General
All wiring must conform to local, state and national
codes.
Voltage
The maximum allowable voltage variation is ± 10% of
the rated voltage on the ice machine model/serial
number plate at start-up (when the electrical load is
highest).
Fuse/Circuit Breaker
A separate fuse/circuit breaker must be provided for
each ice machine. Circuit breakers must be H.A.C.R.
rated (does not apply in Canada).
The ice machine must be grounded in accordance
with national and local electrical codes.

CIRCUIT AMPACITY
The minimum circuit ampacity is used to help select
the wire size of the electrical supply. (Minimum circuit
ampacity is not the ice machine’s running amp load.)
The wire size (or gauge) is also dependent upon
location, materials used, length of run, etc., so it must
be determined by a qualified electrician.
