Location of the Ice Machine
The location selected for the ice machine must 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 per-
formed from the top of the ice machine.
• The location must be free of airborne and other con-
taminants.
• Do not place the unit within 18" (457) of a trash com-
pactor or trash/recycling container.
• The air temperature must be at least 50°F (10°C).
But, the air temperature 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 equip-
ment.
• 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 are designed and
approved for outdoor installation.
The ice machine must be protected if it will be sub-
jected to ambient temperatures below 32°F (0°C).
Component failure caused by exposure to freezing
temperatures is not covered by the warranty.
Area Requirements
Before moving the ice machine into place, be sure the
finished opening dimensions, electrical location and
plumbing location are accurate.
Be sure the plumber, electrician and cabinet installer
have this information before finishing work is complet-
ed.
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 con-
nection.
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 found later in this
section.
NOTES:
•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.
•The floor under the ice machine must be at the same
level as the surrounding finished floor.
•When moving the unit, use a hand truck or dolly, posi-
tion 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 with
appropriate material to avoid any damage from
moving the unit.

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
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.
NOTE: All National Electrical Code regulations must be
followed. In addition, be aware of local codes and ordi-
nances when installing the services.
Voltage
• 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.

PLUMBING REQUIREMENTS
NOTE: Plumbing must conform to state and local
codes.
Water Supply
Prepare water supply line and drain before installation
of the 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 sup-
plied with a drain hose for gravity draining. The option-
al 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 for-
mation, 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 replace-
ment is required.
Water Inlet Lines
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.)
• If water pressure exceeds the maximum recommend-
ed pressure (80 psi–551.5 kPA), obtain a water pres-
sure regulator from a local plumbing contractor.
• Install a water shut-off valve for the ice making water
lines.
• Insulate the water inlet line to prevent condensation.
Drain Connections
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 1-1/2” drop per 5 feet of run
(2.5 cm per meter), and must not create traps.
• The floor drain must be large enough to accommo-
date 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).
APPROXIMATE HEIGHT OF
ICE MACHINE DRAIN
Standard Installation 5” (127mm)
Improper drainage can lead to water flowing back
into ice machine and poor performance.

#7012423 - Revision B - May, 2011
NOTES
• If air temperature is less than 60°F (16°C), water temperature must be equal to or greater than 50°F (10°C).
• Plumbing must conform to state and local codes.
• 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 Cement 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.
