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 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).

• The ice machine and bin must be level

• Vent the ice machine and bin drains separately

• Bin drain termination must have an air gap

• A back flow preventer is required on water inlet

lines

• Routine adjustments and maintenance procedures

outlined in this manual are not covered by the

warranty.

8 Part Number STH48 6/15

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.

ICE MACHINE CLEARANCE REQUIREMENTS

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.

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.
