Installation Section 2
Electrical Requirements
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
(dedicated circuit) must be provided
for each ice machine head section, or
condensing unit.
• 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).
nWarning
All wiring must conform to local, state and
national codes.
Voltage
The maximum allowable voltage variation
is +10%/‑5% of the rated voltage at ice
machine start‑up (when the electrical load
is highest).
nWarning
The ice machine must be grounded
in accordance with national and local
electrical codes.
Fuse/Circuit Breaker
A separate electrical disconnect, which
disconnects all poles and has 1/8" (3 mm)
contact separation, must be provided
for fixed wiring. Circuit breakers must be
H.A.C.R. rated in USA.
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) also depends
on location, materials used, length of
