Section 2 Installation Instructions
Electrical Service
GENERAL
WARNING
All wiring must conform to local, state and national
codes.
VOLTAGE
The maximum allowable voltage variation is ± 10% of the
rated voltage on the ice machine model/serial number plate at
start-up (when the electrical load is highest).
The 115/1/60 ice machines are factory pre-wired with a 6’
power cord, and NEMA 5-20P-plug configuration.
The 208-230/1/60 and 230/50/1 ice machines are factory pre-
wired with a 6’ power cord only, no plug is supplied.
FUSE/CIRCUIT BREAKER
A separate fuse/circuit breaker must be provided for each ice
machine. Circuit breakers must be H.A.C.R. rated (does not
apply in Canada).
WARNING
The ice machine must be grounded in accordance
with national and local electrical codes.
TOTAL CIRCUIT AMPACITY
The total circuit ampacity is used to help select the wire size
of the electrical supply.
The wire size (or gauge) is also dependent upon location,
materials used, length of run, etc., so it must be determined by
a qualified electrician.
GROUND FAULT CIRCUIT INTERUPTER
Ground Fault Circuit Interupter (GFCI/GFI) protection is a
system that shuts down the electric circuit (opens it) when it
senses an unexpected loss of power, presumably to ground.
Manitowoc Ice, Inc. does not recommend the use of a
GFCI/GFI circuit protection with our equipment. If code
requires the use of a GFCI/GFI then you must follow the local
code. The circuit must be dedicated, sized properly and there
must be a panel GFCI/GFI breaker. We do not recommend
GFCI/GFI outlets as they are known for more intermittent
nuisance trips than panel breakers.

For United Kingdom Only
As the colours of the wires in the mains lead of the appliance may not correspond with the coloured
markings identifying the terminals in your plug, proceed as follows:
• The wire which is coloured green and yellow
must be connected to the terminal in the plug which is
marked with the letter E or by the earth ground symbol
or coloured green or green and yellow.
• The wire coloured blue
must be connected to the terminal which is marked with the letter N or coloured
black.
• The wire coloured brown
must be connected to the terminal which is marked with the letter L or
coloured red.
