Sub‑Zero Undercounter Ice Machine
IMPORTANT NOTE: The importance of the installation
of the Sub‑Zero ice machine cannot be overemphasized.
Installation must be completed by a qualied installer.
Read this entire installation guide prior to installation.
There are key details that you should observe during the
installation to make the process easier, problem‑free and,
most importantly, safe. The homeowner should keep this
installation guide for future reference.
Any questions or problems regarding the installation
should be directed to your authorized Sub‑Zero dealer
or Sub‑Zero customer care at 800‑222‑7820. You may
also check the contact & support section of our website,
subzero.com.
Important product information, including the model and
serial number of your unit are listed on the product rating
plate, located in the upper left corner of the ice bin and on
the back of the unit. Refer to the illustration below.
Proper installation requires connection to the water
supply, a drain and a dedicated electrical circuit. These
connections are the responsibilities of the installer.
Improper connections can result in personal injury,
property damage and improper operation.

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.
Incorrect polarity can lead to erratic ice machine oper‑
ation and a safety issue.
Do not use an extension cord or two-prong adapter.
Electrical ground is required on this appliance.
