Electrical Requirements - Sub-Zero UC-15I Service Manual

Installation Information

ELECTRICAL REQUIREMENTS

Prepare electrical circuit before installation of the ice
machine. Installation requires a grounded (three-
prong), polarized receptacle (See Figure 2-2), with a
separate fuse/circuit breaker in an electrical service
box.
Proper Three-Prong Polarized Receptacle
NOTE: All National Electrical Code regulations must be
followed. In addition, be aware of local codes and ordi-
nances when installing the services.
Voltage
ELECTRICAL SHOCK HAZARD. DO NOT USE AN
EXTENSION CORD OR TWO PRONG ADAPTER.
ELECTRICAL GROUND IS REQUIRED ON THIS
APPLIANCE. DO NOT REMOVE THE POWER SUP-
PLY CORD GROUND PRONG.
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.
• The maximum allowable voltage variation
is +/-10% of the rated voltage at ice
machine start-up (when the electrical load
is highest).

• The minimum wire size is #14 for less than 100 feet
(30.5 m) or #12 for more than 100 feet (30.5 m) to
200 feet (61 m) (solid copper conductor only). The
recommended breaker is 15 amp. Local or state
electrical code, length of run or materials used, can
increase the minimum wire gauge required. A quali-
fied electrician must determine the proper wire size,
although #14 is the minimum size allowed.
NOTE: Observe correct polarity of incoming line volt-
age. Incorrect polarity can lead to erratic ice machine
operation and a safety issue.
Minimum Circuit Requirements
The minimum circuit requirement is used to help select
the wire size of the electrical supply.
NOTE: Minimum Circuit Amps listed below is not the
ice machine's running amp load.

GFCI Requirements
For Models UC-15IO and UC-15IPO or if a GFCI
(ground fault circuit interrupter) is required by local elec-
trical code, it must be breaker type.
