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.
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 provided for
each ice machine.
• A qualified electrician must determine proper wire
size dependent upon location, materials used and
length of run (minimum circuit ampacity can be used
to help select the wire size).
• The maximum allowable voltage variation is +/-10 of
the rated voltage at ice machine start-up (when the
electrical load is highest).
• Check all green ground screws in the control box and
verify they are tight before starting the ice machine.
Part Number 80-1620-3
Warning
!
! Warning
Observe correct polarity of incoming line voltage.
Incorrect polarity can lead to erratic ice machine
operation and a safety issue. This is especially critical on
230 volt / 50 cycle ice machines.
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.
