Section 2

Electrical Service

!
All electrical work, including wire routing and
grounding must conform to all applicable national and
local electrical codes.

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.
• A separate fuse/circuit breaker must be provided for
each ice machine.
• The wire size (or gauge) is dependent upon location,
materials used, length of run, etc., so it must be
determined by a qualified electrician.
• The ice machine must be grounded. Check all green
ground screws in the control box and verify they are
tight before starting the ice machine.
• The maximum allowable voltage variation is ±10% of the
rated voltage at ice machine start-up (when the
electrical load is highest).
! Caution
Observe correct polarity of incoming line voltage.
Incorrect polarity can lead to erratic ice machine
operation. Operate equipment only on the type of
electricity indicated on the specification plate.

Warning

GROUND FAULT CIRCUIT INTERRUPTER

Ground Fault Circuit Interrupter (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.
GFCI/GFI circuit protection is not recommended 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.

If a power cord is used, the wire size to the receptacle is
dependent upon location, materials used, length of run, etc.,
so it must be determined by a qualified electrician. Local,
state or national requirements will supersede our minimum
requirements.

FOR UNITED KINGDOM ONLY

As the colors of the wires in the mains lead of the appliance may not
correspond with the colored markings identifying the terminals in your
plug, proceed as follows:
• The wire which is colored 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
• The wire colored blue must be connected to the terminal which is
marked with the letter N or colored black.
• The wire colored brown must be connected to the terminal which is
marked with the letter L or colored red.
