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 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 40°F

(4°C), but must not exceed 90°F (32°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.

• RF Models Only: A backflow preventer is required

on water inlet lines.

• Routine adjustments and maintenance procedures

outlined in this manual are not covered by the

warranty.

10 Part Number 000007661 7/10

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

(70 psig [483 kPa] RN1000; 80 psig [552 kPa] for

all other models) obtain a water pressure regulator

from your Manitowoc distributor.

• A water shut-off valve is required to clean the ice

machine.

• A union for both the ice making and condenser

water lines is required.

• Water inlet lines require insulation to prevent

condensation.

• RF Models: A backflow preventer is required on

water inlet lines.

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.
