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 1.6°C, but must
not exceed 43.4°C.
• The location must not be near heat-generating
equipment or in direct sunlight.
• The location must not obstruct air flow through or
around the ice machine. Refer to the chart below for
clearance requirements.
Stacking Two Ice Machines on a Single
Storage Bin
A stacking kit is required for stacking two ice machines.
Installation instructions are supplied with the stacking kit.
Ice Machine 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 aircooled 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.

Leveling the Ice Storage Bin
1. Screw the leveling legs onto the bottom of the bin.
2. Screw the foot of each leg in as far as possible.
3. Move the bin into its final position.
4. Level the bin to assure that the bin door closes and
seals properly. Use a level on top of the bin. Turn
each foot as necessary to level the bin.
NOTE: An optional caster assembly is available for use
in place of the legs. Installation instructions are supplied
with the casters.
Leveling Leg and Foot
Air-Cooled Baffle
The air-cooled baffle prevents condenser air from
recirculating. To install:
1. Remove the back panel screws next to the
condenser.
2. Align the mounting holes in the air baffle with the
screw holes and reinstall the screws.

Caution
The legs must be screwed in tightly to prevent them
from bending.

Electrical Service
GENERAL
VOLTAGE
The maximum allowable voltage variation is ±10% of the
rated voltage at ice machine 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.
GROUND FAULT CIRCUIT INTERUPTER
Ground Fault Circuit Interupter (GFCI/GFI) protection is
a system that shuts down the electric circuit (opens it)
when it senses an unexpected loss of power,
presumably to ground. Manitowoc Ice, Inc. does not
recommend the use of a GFCI/GFI circuit protection with
our equipment. If code requires the use of a GFCI/GFI
then you must follow the local code. The circuit must be
dedicated, sized properly and there must be a panel
GFCI/GFI breaker. We do not recommend GFCI/GFI
outlets as they are known for more intermittent nuisance
trips than panel breakers.
MINIMUM 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.
!
Warning
All wiring must conform to local and national codes.
!
Warning
The ice machine must be grounded in accordance
with national and local electrical codes.
