Installation
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.
• Air temperature:
• Q130/Q170/Q210/Q270/QM45 must be at
least 40°F (4°C) but must not exceed 110°F
(43.4°C).
• QM20/QM30 must be at least 50°F (10°C) but
must not exceed 113°F (45°C).
• SM50 must be at least 50°F (10°C) but must
not exceed 110°F (43°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 (condenser airflow is in
and out the front). Refer to the chart below for
clearance requirements.
• 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.

** 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 self-contained
air-cooled ice machines are installed.

1. Screw the leveling legs onto the bottom of the ice
machine.
2. Screw the foot of each leg in as far as possible.
The legs must be screwed in tightly to prevent
them from bending.
3. Move the ice machine into its final position.
4. Level the ice machine to ensure that the siphon
system functions correctly. Use a level on top of
the ice machine. Turn each foot as necessary to
level the ice machine from front to back and side
to side.
NOTE: An optional 2-1/2" (6.35 cm) caster assembly is
available for use in place of the legs on the Q130,
Q170, Q210, Q270, or QM45. Installation instructions
are supplied with the casters.

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. Use a level to check the levelness of the ice
machine from front to back and from side to side.
2. If the ice machine is not level, adjust the leveling
glides or legs on each corner of the base of the
ice machine as necessary.
3. Check the levelness of the ice machine after each
adjustment.
4. Repeat steps 2 and 3 until the ice machine is level
from front to back and from side to side.

Electrical Requirements
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).
The 115/1/60 ice machines are factory pre-wired with
a 6' (1.8 m) power cord, and NEMA 5-15P-plug
configuration.
The 208-230/1/60 and 230/1/50 ice machines are
factory pre-wired with a power cord only, no plug is
supplied.
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).
TOTAL CIRCUIT AMPACITY
The total circuit ampacity is used to help select the
wire size of the electrical supply.
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.
