Electrical Service
GENERAL
VOLTAGE
The maximum allowable voltage variation is  10% of
the rated voltage on the ice machine model/serial
number plate at start-up (when the electrical load is
highest).
The 115/1/60 ice machines are factory pre-wired with a
8’ power cord, and NEMA 5-15P-plug configuration.
The 208-230/1/60 and 230/50/1 ice machines are
factory pre-wired with a 8’ power cord only, no plug is
supplied.
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).
TOTAL CIRCUIT AMPACITY
The total circuit ampacity is used to help select the wire
size of the electrical supply.
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.
GROUND FAULT CIRCUIT INTERRUPTER
Ground Fault Circuit Interrupter (GFCI/GFI) protection is
a system that shuts down the electric circuit (opens it)
when it senses an unexpected loss of power,
presumably to ground. Koolaire does not recommend
the use of a GFCI/GFI circuit protection with our
equipment. If code requires the use of a GFCI/GFI then
you must follow the local code. The circuit must be
dedicated, sized properly and there must be a panel
GFCI/GFI breaker. We do not recommend GFCI/GFI
outlets as they are known for more intermittent nuisance
trips than panel breakers.
K130/K170/K210/K270 ICE MACHINE
! Warning
All wiring must conform to local, state and national
codes.
! Warning
The ice machine must be grounded in accordance
with national and local electrical codes.
! Warning
PERSONAL INJURY POTENTIAL
If the supply cord is damaged, do not operate the
equipment until the cord is replaced by a service
agent or similarly qualified person.
