Electrical Service
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).
GROUND FAULT INTERRUPTER CIRCUIT (GFIC)
Ground Fault Circuit Interrupter protection is a system
that shuts down the electric circuit (opens it) when it
senses an unexpected loss of power, presumably to
ground. Manitowoc Ice, Inc. 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
(accept QuietQubes), 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.
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).
QF400 115/60/1 ice machines are factory pre-wired
with a power cord and 5-15P plug confirmation.
QF400 230/50/1 ice machines are factory pre-wired
with a power cord, no plug is supplied.
QF2300 with Remote Condensing Unit the ice
machine head section and remote condensing unit are
wired independent of each other. A separate dedicated
fuse/circuit breaker must be provided
for each section.
Circuit breakers must be H.A.C.R. rated (does not apply
in Canada).
TOTAL CIRCUIT AMPACITY
QF400 Only
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.
MINIMUM CIRCUIT AMPACITY
QC700/QF800/QF2300 Only
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.
!
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.
