open site (gravity) drain available
(see page 8).
A grounded, polarized electrical power
supply on a separate circuit servicing only
this appliance is required. If GFCI (ground
fault circuit interrupter) is required by your
local electrical code or in an outdoor installation, it must be breaker type, not outlet
type (see page 7).
Must have cold water supply line available
at ice machine (see page 8).
Clearance and air temperature requirements
must be met (see page 6).
If built into a cabinet, ice machine must be
removable for yearly cleaning procedure
(see page 23).
Proper installation requires connection to
the water supply, a drain and a dedicated
lectrical circuit. These connections are
e
the responsibilities of the owner/operator.
Improper connections can result in
personal injury, substantial property
damage and erratic machine operation. If
ou are unsure of your ability to safely
y
connect the ice machine, consult qualified
professionals or contact Sub-Zero.
IMPORTANT NOTE:
Failure to follow these
installation guidelines may affect warranty
coverage.

meet the following criteria. If any of these
criteria are not met, select another location.
The ice machine may be built into a
cabinet, however the location must allow
removal of the ice machine for cleaning and
servicing. Service diagnostics are
performed from the top of the ice machine.
The location must be free of airborne and
other contaminants.
Do not place the unit within 18" (457) of a
trash compactor or trash/recycling
container.
The air temperature must be at least 50°F
(10°C), but must not exceed 100°F (38°C) for
models UC-15I and UC-15IP and 110°F
(43°C) for models UC-15IO and UC-15IPO.
The location must not be near heat-generating equipment.
The location must not obstruct air flow
through the kickplate (airflow is in and out
the front of the ice machine).
The location must allow enough clearance
for water, drain and electrical connections
at the rear of the ice machine.
Models UC-15IO and UC-15IPO may be
installed outside.

efer to pages 7–11.
R
Be sure your plumber, electrician and
cabinet installer have this information before
finishing work is completed.
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 nearby sink. Refer to
specifications on pages 8–9.
IMPORTANT NOTE:
If the ice machine is
installed in a corner, the door swing may be
limited due to handle contact with the wall
or cabinet face.
IMPORTANT NOTE:
The floor under the
ice machine must be at the same level as the
surrounding finished floor.
IMPORTANT NOTE:
When you move the
unit using a hand truck or dolly, position the
dolly on the side of the unit and secure the
door so it does not open while transporting
the unit.
Any finished flooring should be protected
The ice machine must be protected if it
will be subjected to ambient temperatures below 32°F (0°C). Component failure
caused by exposure to freezing temperatures is not covered by the warranty. See

Do not use an extension cord or twoprong adapter. Electrical ground is
required on this appliance. Do not remove
the power supply 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:
MPORTANT NOTE:Observe correct

Incorrect polarity can lead to erratic ice
machine operation and a safety issue.

You must follow
all National
Electrical Code
regulations. In
addition, be aware
of local codes and
ordinances when
installing your
services.
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 qualified electrician must determine the
proper wire size, although #14 is the
minimum size allowed.

Prepare water supply line and drain before
installation of your ice machine. Installation
requires a minimum
1
/4" ID copper cold water
line and compression fitting (not supplied).
Models UC-15I and UC-15IO are supplied with
a drain hose for gravity draining. The optional
drain pump or pump models UC-15IP and
UC-15IPO must be purchased if a gravity drain
is not possible. Both drain methods require
routing to an open site drain. Do not connect
directly to drain line as bacteria from drain line
may contaminate the ice machine.
The included water filter is designed to inhibit
scale formation, filter sediment, and remove
chlorine odor and taste. The life expectancy of
the water filter is 6 months during normal
usage. The ice machine control board will
monitor water usage and indicate when
replacement is required.
W A T E R I N L E T L I N E S
Follow these guidelines to install water inlet
lines:
Do not connect the ice machine to a hot
water supply. Be sure all hot water restrictors installed for other equipment are
working. (Check valves on sink faucets,
dishwashers, etc.)
D R A I N C O N N E C T I O N S
Follow these guidelines when installing drain
lines to prevent drain water from flowing
back into the ice machine and storage bin:
Drain lines must have a 1
eet of run (2.5 cm per meter), and must
f
1
/2" drop per 5
not create traps.
The floor drain must be large enough to
accommodate drainage from all drains.
Drain pump discharge line must terminate at an open site drain.
Maximum rise – 12 feet (3.7 m)
Maximum run – 100 feet (30.5 m)

Improper drainage can lead to water
flowing back into ice machine and poor
performance.
If water pressure exceeds the maximum
recommended pressure (80 psi–551.5 kPA),
obtain a water pressure regulator from your
local plumbing contractor.
Install a water shut-off valve for the ice
making water lines.
Insulate the water inlet line to prevent
condensation.

and local codes.
IMPORTANT NOTE:
Although the ice
machine has been designed to be serviced in
place, in some cases it may be necessary to
pull the unit out for service. For that reason
do not restrict access to the unit at the front,
top and bottom.
If a floor is to be installed after the ice
machine, shims the thickness of the floor
should be installed under the unit to keep the
ice machine level with the floor. Also, allow
1
/8" (3) clearance on each side of the unit for
protruding screw heads.
Installations on a slab:
Use a Model
UC-15IPO or UC-15IP, with built-in drain
pump and pump the water to the point of
drainage. Drain pump models will pump
12 feet (3.7 m) high.
Installations over a crawl space or
basement:
If there is not enough room
behind the ice machine for a drain /waste
water receptacle, the drain will have to be
below the floor.
