Installation Instructions

Installation Prerequisites

• Must have open site (gravity) drain available or
purchase optional drain pump (see W ater Supply and
Drain Requirements).

• Must have a grounded, polarized electrical power
supply on a dedicated electrical circuit (only
appliance on circuit). If GFCI (ground fault circuit
interrupter) is required by your loca l electrical code , it
must be breaker type, not outlet type (see Electrical
Service).

• Must have cold water supply line available at Ice
Machine (see Water Supply and Drain
Requirements).

• Clearance and air temperatures must be met (see
Location of Ice Machine).

• If built into a cabinet, ice machine must be removable
for yearly cleaning procedure (see Interior Cleaning
and Sanitizing in section 3).

General

Call Manitowoc Foodservice at [phone] for the
name of a local company capable of installation and
start-up services.

Proper installation requires connection to the water
supply, a drain and a dedicated electrical circuit.
These connections are the responsibilities of the
owner/operator. Improper connections can result in
personal injury, substantial property damage and
erratic machine operation. If you are unsure of your
ability to safely connect the ice machine, consult
qualified professionals or contact Manitowoc
Foodservice.

Failure to follow these installation guidelines may
affect warranty coverage.

Caution

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 ice machine may be built into a cabinet, however
the location must allow removal of the ice machine
for cleaning and servicing. Service diagnostics are
performed from the top of the ice mach in e. Refer to
Minimum Cut-Out for Built-In Installations on page
2-2.

• 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 location must not be near heat-generating
equipment.

• The location must not obstruct air flow through the
condenser (airflow is in and out the front of the ice
machine).

• The location must allow enough clearance for water,
drain and electrical connections at the rear of the ice
machine.

• The ice machine may be installed outside.

CLEARANCES

Top/Sides 5” (12.7 cm)*

Back 5” (12.7 cm)
Front 24” (60.9 cm)

*The ice machine may be built into a cabinet. There is no minimum clearance
requirement for the top or sides of the ice machine. The listed values are
recommended for efficient operation and servicing only.

The ice machine must be protected if it will be
subjected to ambient temperatures below 32°F
(0°C). Component failure caused by exposure to
freezing temperatures is not covered by the
warranty. See “Removal from Service/
Winterization”.

Warning

Important

Electrical Service

GENERAL

Observe correct polarity of incoming line voltage.

All wiring must conform to local, state and national
codes.

Prepare electrical circuit before installation of your ice
machine. Installation requires a grounded (three-pr ong),
polarized receptacle with a separate fuse/circuit breaker
in an electrical service box.

VOLTAGE

The maximum allowable voltage variation is ±1 0% of the
rated voltage at ice machine star t-up (when the electrical
load is highest).

The ice machine must be grounded in accordance
with national and local electrical codes.

All electrical work, including wire routing and grounding,
must conform to local, state and national electrical
codes. The following precautions must be observed:

• The ice machine must be grounded.

• A separate fuse/circuit breaker must be provide d fo r
each ice machine.

• The maximum allowable voltage variation is +/-10%
of the rated voltage at ice machine start-up (when the
electrical load is highest).

Incorrect polarity can lead to erratic ice machine
operation and a safety issue.

MINIMUM CIRCUIT AMPACITY

The minimum circuit ampacity is used to help select the
wire size of the electrical supply. (Minimum circuit
ampacity is not the ice machine’s running amp load.)

ELECTRICAL REQUIREMENTS

Refer to Ice Machine Model/Serial Plate for voltage/
amperage specifications.

GFCI REQUIREMENTS

If GFCI (ground fault circuit interrupter) is required by
local electrical code, it must be breaker type.

• Check all green ground screws in the control box and
verify they are tight before starting the ice machine.

• Manitowoc’s recommended minimum wire size is
#14 for less than 100’ or #12 for more than 100’ to
200’ (solid copper conductor only). The
recommended breaker is 15 amp. Local or state
electrical code, length of run or materials used, can
increase the minimum wire gauge required. A
qualified electrician must determine the pr op er w ire
size, although #14 is the minimum size allowed.

Water Supply and Drain Requirements

WATER SUPPLY

Prepare water supply line and drain before in stallation of
your ice machine. Installation requires a 1/4" ID copper
cold water line and compression fitting (not supplied).
The ice machine is supplied with a drain hose for gravity
draining. The optional drain pump must be purchased if
a gravity drain is not possible. Both drain methods
require routing to an open site drain. Do not connect
directly to drain line as bacteria from drain line may
contaminate the ice machine.

The included water filter is designed to inhibit scale
formation, filter sediment, and remove chlorine odor and
taste. The life expectancy of the water filter is 6 months
during normal usage. The ice machine control board will
monitor water usage and indicate when replacement is
required.

WATER INLET LINES

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.)

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.

• Drain pump discharge line must terminate at an open
site drain.

• Maximum rise - 12 feet (3.7 m)

• Maximum run - 100 feet (30.5 m)

Approx. Height of Ice Machine Drain

Standard Installation 3" (76 mm)

Installation with Leg Option 7" (179 mm)

• If water pressure exceeds the maximum
recommended pressure (80 psi - 55 bar), obtain a
water pressure regulator from your Manitowoc
distributor.

• Install a water shut-off valve for the ice making water
lines.

• Insulate the water inlet line to prevent condensation.
