Environmental Requirements
This model is intended for indoor/interior applications only
and is not to be used in installations that are open/
exposed to natural elements.
This unit is designed to operate between 50°F (10°C) and
100°F (38°C). Higher ambient temperatures may reduce
the unit’s ability to reach low temperatures and/or reduce
ice production on applicable models.
For best performance, keep the unit out of direct sunlight
and away from heat generating equipment.
In climates where high humidity and dew points are
present, condensation may appear on outside surfaces.
This is considered normal. The condensation will
evaporate when the humidity drops.
! CAUTION
Damages caused by ambient temperatures of
40°F (4°C) or below are not covered by the
warranty.

! WARNING
SHOCK HAZARD — Electrical Grounding
Required. Never attempt to repair or perform
maintenance on the unit until the electricity has
been disconnected.
Never remove the round grounding prong from
the plug and never use a two-prong grounding
adapter.
Altering, cutting or removing power cord,
removing power plug, or direct wiring can cause
serious injury, fire, loss of property and/or life,
and will void the warranty.
Never use an extension cord to connect power to
the unit.
Always keep your working area dry.
NOTICE
Electrical installation must observe all state and
local codes. This unit requires connection to a
grounded (three-prong), polarized receptacle
that has been placed by a qualified electrician.
The unit requires a grounded and polarized 115 VAC,
60 Hz, 15A power supply (normal household current). An
individual, properly grounded branch circuit or circuit
breaker is recommended. A GFCI (ground fault circuit
interrupter) is usually not required for fixed location
appliances and is not recommended for your unit because
it could be prone to nuisance tripping. However, be sure
to consult your local codes.
See CUTOUT DIMENSIONS for recommended receptacle
location.

height of 1/8" (3 mm) less than the opening’s rear height.
Shorten the unit height in the front by adjusting the front
legs. This allows the unit to be gently tipped into the
opening. Readjust the front legs to level the unit after it is
correctly positioned in the opening.

High ambient temperature and excessive humidity can
also produce frost.
! CAUTION
DO NOT use an ice pick or other sharp
instrument to help speed up defrosting. These
instruments can puncture the inner lining or
damage the cooling unit. DO NOT use any type of
heater to defrost. Using a heater to speed up
defrosting can cause personal injury and
damage to the inner lining.
NOTICE
The drain pan was not designed to capture the
water created when manually defrosting. To
prevent water from overflowing the drain pan,
place towels or other absorbent materials over
the interior drain trough (under the evaporator)
before defrosting.
To defrost:
1. Disconnect power to the unit.
2. Remove all products from the interior.
3. Prop the door in an open position (2 in. [50 mm]
minimum).
4. Allow the frost to melt naturally.
5. After the frost melts completely clean the interior and

Extended Non-Use
VACATION/HOLIDAY, PROLONGED SHUTDOWN
The following steps are recommended for periods of
extended non-use:
1. Remove all consumable content from the unit.
2. Disconnect the power cord from its outlet/socket and
leave it disconnected until the unit is returned to
service.
3. If ice is on the evaporator, allow ice to thaw naturally.
4. Clean and dry the interior of the unit. Ensure all water
has been removed from the unit.
5. The door must remain open to prevent formation of
mold and mildew. Open door a minimum of 2"
(50 mm) to provide the necessary ventilation.
WINTERIZATION
If the unit will be exposed to temperatures of 40°F (5°C)
or less, the steps above must be followed.
For questions regarding winterization, please
call U-Line at +1.800.779.2547.

All models incorporate rigid foam insulated cabinets to
provide high thermal efficiency and maximum sound
reduction for its internal working components. Despite this
technology, your model may make sounds that are
unfamiliar.
Normal operating sounds may be more noticeable because
of the unit’s environment. Hard surfaces such as cabinets,
wood, vinyl or tiled floors and paneled walls have a
tendency to reflect normal appliance operating noises.
Listed below are common refrigeration components with a
brief description of the normal operating sounds they
make. NOTE: Your product may not contain all the
components listed.
• Compressor: The compressor makes a hum or pulsing
sound that may be heard when it operates.

• Temperature setting.
• Ambient temperature where installed.
• Installation in direct sunlight or near a heat source.
• The number of door openings and the time the door is

• The time the internal light is illuminated. (This mainly
affects product on the top rack or shelf.)
CHECKING PRODUCT TEMPERATURE
To check the actual product temperature in the
unit:
1. Partially fill a plastic (nonbreakable) bottle with water.
2. Insert an accurate thermometer.

NOTICE
Use only genuine U-Line replacement parts. The
use of non-U-Line parts can reduce speed of ice
production, cause water to overflow from ice
maker mold, damage the unit, and void the
warranty.
Warranty parts will be shipped at no charge after U-Line
confirms warranty status. Please provide the model, serial
number, part number and part description. Some parts
will require color or voltage information.
If U-Line requires the return of original parts, we will
inform you when the parts order is taken. This
requirement will be noted on your packing list. A prepaid
shipping label will be included with the replacement part.
Please enclose a copy of the parts packing list and any
labor claims with your return. Please be sure the model
and serial numbers are legible on the paperwork. Tag the
part with the reported defect.
When ordering a non-warranty part, you will need an open
account and tax exemption on file at U-Line. Another
option would be to visit www.u-line.com to locate an
authorized parts distributor in your area.

Always assure that all thermistor connections are clean
and dry. Whenever opening a thermistor connection be
sure to apply a fresh dab of die electric grease.
REED SWITCH
A reed switch is used to monitor door state. When the
door is closed magnetic force pulls the reed to its contact
and closes the circuit which turns the light and display off.
When the door is open the reed pulls away from the
contact and opens the circuit. If the door is left open for
longer than 5 minutes, the switch will trigger an error code
and set an audible warning.

Thermistor two is located on the back of the evaporator

Thermistor connections must be kept clean. A thermistor
connection that has become corroded can cause
resistance values from the thermistor to change as they
pass through a dirty connection to the board.
It is for that reason that we apply die electric grease to all
of our thermistor connections. Die electric grease will help
to keep thermistor connections clean and dry.
If you change a thermistor in the unit please re-apply die
electric grease to the connection. If you encounter a dirty
thermistor connection, you should replace the thermistor
and the thermistor harness.
