Installation Instructions

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 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 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.

NOTE: Allowance must be made for removal when the
ice machine is built in. Monthly removal of the top
panel is required for cleaning & sanitizing.

Air-Cooled Water-Cooled

Installation Requirements

• 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 backflow preventer is required on water inlet lines.

• The ice machine and bin must be sanitized after
installation.

• Local water conditions may require treatment of the
water to inhibit scale formation, filter sediment, and
remove chlorine odor and taste.

• Routine adjustments and maintenance procedures
outlined in this manual are not covered by the
warranty.

RF-2300 Bin Adapter Installation

PERSONAL INJURY POTENTIAL

RF-2300 ice machines are not approved for use on
B970 bins. RF-2300 ice machines ship with a
bracket that must be used when installing on B1100
and B1400 Series bins.

1. Refer to diagram. Place bracket on bin top and slide
back to engage.

2. Place ice machine on bin: ice machine must fit
between bracket and front ridge.

Water and Drain Requirements

POTABLE WATER REQUIREMENTS

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.)

• If water pressure exceeds the maximum of 80 psig
(6 bar) recommended pressure, obtain a water
pressure regulator from your Manitowoc distributor.

• Install a water shut-off valve and union for both the
ice making and condenser water lines.

• Insulate water inlet lines to prevent condensation.

• Plumbing must conform to local codes.

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 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.

• Run separate bin and water-coole d condenser drain
lines. Insulate them to prevent condensation.

Part Number 000005653 10/09 5

Typical Water Su pply Drain Installation

• Vent the bin and ice machine drain to the
atmosphere. The ice machine drain requires an 18"
(46 cm) vent. Do not vent the condenser drain on
water-cooled models.

• Drains must have a union or other suitable means to
allow in place disconnection from the ice machine
when servicing is required.
