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.
