the following criteria. If any of these criteria are not
met, select another location.

contaminants.
• 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.
INSTALLATION REQUIREMENTS
• The air temperature must be at least 50°F (10°C),
but must not exceed 110°F (43°C).
• The water temperature must be at least 50°F
(10°C), but must not exceed 100°F (38°C).

POTABLE WATER REQUIREMENTS
• Plumbing must conform to local codes
• 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.)
• If water pressure exceeds maximum pressure (6
bar) obtain a water pressure regulator from your
Manitowoc distributor.
• A union for both the ice making and condenser
water lines is required
• Water inlet lines require insulation to prevent
condensation.
DRAIN CONNECTIONS
• Drain lines must have a 1.5 inch drop per 5 feet of
run (2.5 cm per meter), and must not create traps
• The floor drain must be large enough to
accommodate drainage from all drains.
• Separate insulated bin and water-cooled
condenser drain lines are required
• The bin and ice machine drains require a vent.

ELECTRICAL SERVICE
Voltage
The maximum allowable voltage variation is ± 10% of
the rated voltage on the ice machine model/serial
number plate at compressor start-up.
Fuse/Circuit Breaker
A separate fuse/circuit breaker must be provided for
each ice machine.
Ground Fault Interrupter Circuit (GFIC)
A GFCI/GFI circuit protection is not recommended
with our equipment. If a GFCI/GFI is required by code
a GFCI/GFI breaker rather than outlet must be used to
avoid intermittent nuisance trips.
