Electrical Requirements
The ice machine must be installed with adequate clear‑
ance for electrical connection at the rear of the unit. The
electrical supply for the ice machine requires installation of
a grounded receptacle on a separate circuit, servicing only
this appliance. Follow the National Electrical Code and
local codes and ordinances when installing the receptacle.
IMPORTANT NOTE: Although it can be located anywhere
on the back wall, it is recommended that the receptacle
be placed in an adjacent cabinet or in the lower right of
the opening. If it is placed within the opening, additional
cabinet depth may be required. Refer to the illustration
below.
Models UC15IO and UC‑15IPO are designed and safe for
use in outdoor applications. When installed outdoors, a
ground fault circuit interrupter (GFCI) is required to reduce
the risk of electrical shock. For outdoor models, or if a
ground fault circuit interrupter (GFCI) is required by local
codes, it must be a breaker type, not an outlet type.
Electrical Requirements
Power Supply 115 V AC, 60 Hz
Receptacle 3‑prong grounding‑type
Circuit Breaker 15 amp
Minimum Circuit 4.1 amp
The electrical supply for the ice machine must be installed
by a qualied electrician in accordance with all applicable
national and local electrical codes. Observe the following:
• The ice machine must be grounded in accordance with
national and local electrical codes.
• A separate fuse or 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'
or #12 for more than 100'
(31 m) to 200' (61 m), use solid
(31 m)
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 qualied electrician must determine the
proper wire size, although #14 is the minimum size
allowed.
• The minimum circuit requirement is used to help select
the wire size of the electrical supply. Minimum circuit
requirement is not the ice machine’s running amp load.
• Observe correct polarity of incoming line voltage.

DRAIN CONNECTION
Models UC‑15I and UC‑15IO are gravity drain models that
require a drain tube that is pitched down from the outlet
at the back of the unit to the sanitary sewer connection.
Models UC‑15IP and UC‑15IPO have a built in drain pump
that will pump water up to a drain point, such as a sink.
Gravity drain models are supplied with a drain hose for
gravity draining. A pump model must be used if a gravity
drain is not possible. Both drain methods require routing
to an open site drain. Do not connect directly to a drain
line as bacteria from the drain line may contaminate the
ice machine. Locate the drain in an adjacent cabinet.
Refer to the illustrations below. For installations that will
not allow the drain to be placed in an adjacent cabinet, the
drain must be located within
1
/2" (13) of the back wall.
