Installation Instructions Section 2
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 1.6° C (35°F),
but must not exceed 43.4°C (110°F).
• 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 ic e
machine.
• The location must not obstruct airflow through or
around the ice machine (condenser airflow is in and
out the front). Refer to the chart below for clearance
requirements.
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 aircooled ice machines are installed.
Leveling the Ice Machine
After moving the ice machine into the installation
location, it must be leveled for proper operation. Follow
these steps to level the ice machine:
1. Check the level of the ice machine from front to back
and from side to side.
Self-Contained Air-Cooled
Top/Sides 5” (127 mm)*
Back 5” (127 mm)*
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” Section 4.

Section 2 Installation Instructions
Electrical Service
!
Warning
All wiring must conform to local, state and national
codes.
Voltage Phase Total Amps
Never use an extension cord. If an outlet is not
within reach of the ice machine’s power cord, have
a proper amperage outlet wired closer to the ice
machine.
!
Warning
230/50/1 2.6
115/60/1 5.2
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).
!
Warning
The ice machine must be grounded in accordance
with national and local electrical codes.
FUSE/CIRCUIT BREAKER
A separate fuse/circuit breaker must be provided for
each ice machine.
NOTE: A disconnect means must be provided for field
wiring.
ELECTRICAL RATING
The electrical rating is used to help select the wire size
of the electrical supply. The wire size (or gauge) also
depends on location, materials used, length of run, etc.,
so it must be determined by a qualified electrician.
