bserve correct
polarity of incoming line voltage.
Incorrect polarity can lead to erratic ice
machine operation and a safety issue.

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

repare electrical circuit before installation of
your ice machine. Installation requires a
grounded (three-prong), polarized receptacle
w
ith a separate fuse/circuit breaker in an elec-
trical service box.

All electrical work, including wire routing and
grounding, must conform to local, state and
national electrical codes. The following precau-
tions must be observed:
The ice machine must be grounded.
A separate fuse/circuit breaker must be
provided for 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).
The minimum wire size is #14 for less than
100 feet (30.5 m) or #12 for more than 100
feet (30.5 m) to 200 feet (61 m) (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
proper wire size, although #14 is the
minimum size allowed.
Do not use an extension cord or two-
prong adapter. Electrical ground is
required on this appliance. Do not remove
the power supply cord ground prong.
