Electrical Service

GENERAL

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

VOLTAGE

The maximum allowable voltage variation is ±10% of the
rated voltage at ice machine start-up (when the electrical
load is highest).
The ice machine must be grounded in accordance
with national and local electrical codes.

Observe correct polarity of incoming line voltage.
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).

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.)
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.

ELECTRICAL REQUIREMENTS

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