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,
condenser 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).
Warning
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).
Warning
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 3 mm (3/16") 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 run, etc., so it must be determined by a
qualified electrician.
Ground Fault Circuit Interrupter
We do not recommend the use of a GFCI/GFI circuit
protection with our equipment. If a GFCI/GFI is required by
code, use a GFCI/GFI breaker rather than an outlet, which is
more prone to intermittent nuisance trips than panel circuit
breakers.
Important
3-Phase Scroll Compressors Only - Verify the direction
of rotation is correct on the 3-phase scroll compressor.
The ice machine will have high suction pressure, low
discharge pressure and will be noticeably loud. Reverse
any two incoming power leads to reverse rotation.
