Location of Ice Machine
Section 1
Leveling the 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 10°C (50°F), but must
not exceed 43°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 ice machine.
• The location must not obstruct airflow through or aroun d the
ice machine (condenser airflow is in and out the front). Refer
to the chart below for clearance recommendations.

Top/Sides 203 mm (8 in.)* 127 mm (5 in.)*
Back 127 mm (5 in.)* 127 mm (5 in.)*
* 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 0°C (32°F). Failure caused by exposure to
freezing temperatures is not covered by the warranty.
Self-Contained

Levelers are included with all ice machine. Legs are an available
option.
1. Screw the legs or levelers into the bottom of the ice
machine.

2. Screw the foot of each leg or leveler in as far as possible.
Move the ice machine into its final position.
3. Level the ice machine 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.

Installation Instructions
GENERAL
All wiring must conform to local, state and national codes.
WARNING
VOLTAGE
The maximum allowable voltage variation is ± 6% of the rated
voltage on the ice machine model/serial number plate at start-up
(when the electrical load is highest).
All ice machines are factory pre-wired with a 2 meter (6 ft)
power cord, no plug is supplied.

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. An electrical disconnect switch must be provided if the
ice machine is hard wired (wired without a plug).
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., This must be determined by a
qualified electrician.

Water Service/Drains
WATER SUPPLY
Local water conditions may require treatment of the water to
inhibit scale formation, filter sediment, remove chlorine, and
improve taste and clarity.
WATER INLET LINES
Follow these guidelines to install water inlet lines:
• Do not connect the ice machine to a hot water supply. Be
sure all hot water restrictors installed for other equipment are
working. (Check valves on sink faucets, dishwashers, etc.)
• Water pressure to the machine should be between 1.4 to 5.5
bar (20 to 80 psi).
• If water pressure exceeds the maximum 5 bar recommended
pressure, obtain a water pressure regulator from your
Manitowoc distributor. Adjust pressure to 2.5 bar (37 psi).
• Install a water shut-off valve.
• Connect to a potable water supply only.

If you are installing a water filter system, make sure that
you use a separate line for water-cooled condenser.
Filter life will be greatly reduced if filtered water is used
for water-cooled condenser.
DRAIN CONNECTIONS
Follow these guidelines when installing drain lines to prevent
drain water from flowing back into the ice machine and storage
bin:
• Drain lines must have a 3.8 cm (1.5 inch) drop of run for
each meter (3 feet), and must not create traps.
• The floor drain must be large enough to accommodate
drainage from all drains.
• Run separate bin and water-cooled condenser drain lines.
Insulate them to prevent condensation
