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.

Shorten the unit height in the front by adjusting the front
legs. This allows the unit to be gently tipped into the

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]

Adjust the temperature to a cooler set point.
Ensure unit is not located in excessive
ambient temperatures or in direct sunlight.
Ensure the door is closing and sealing
properly.
Ensure the interior light has not remained
on too long.
Ensure nothing is blocking the front grille,
found at the bottom of the unit.
Ensure the condenser coil is clean and free
of any dirt or lint build-up.
6. After 24 hours, check the temperature of the water. If
required, adjust the temperature control in a small
increment (see CONTROL OPERATION).
Causes which affect the internal temperatures of
the cabinet include:
• 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
open.
• 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.
3. Tighten the bottle cap securely.
4. Place the bottle in the desired area for 24 hours.
5. Avoid opening the unit during the testing period.

Product Liability
Field service technicians are authorized to make an initial
assessment in the event of reported damages. If there are
any questions about the process involved, the technician
should call U-Line for further explanation.
While inspecting for defects or installation issues, photos
should be taken to document any damages or issues
found.
During the assessment, if the service technician is able to
find the source of the damage and it can be resolved by
replacement of a part, the servicer is authorized to
replace the part in question. The part that caused the
damage must be returned to U-Line in its entirety. The
part must be clearly labeled with the serial number of the
unit it was removed from, the date, and the servicer who
removed the part.
If the service technician determines the damage is the
result of installation issues (water connection/drain, etc.),
the consumer would be notified and the issues shall be
resolved at the direction of the consumer.
If damage is evident and the service technician is unable
to find the source, U-Line must be contacted at 1-800799-2547 for further direction

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

(DO NOT MAKE AN ADJUSTMENT TO THIS WITHOUT
CONTACTING TECH LINE: 800-779-2547)
This calibration is only to be used if actual
temperature at thermistor #1 is off from set
point.
By adjusting the offset higher we can force the
unit to drive the temperature down below the set
point. (example: adjusting from 0 to +2 will drop
the unit temperature 2 degrees)

HOURS
This will adjust the interval between defrosts
from 3 to 24 hours. Adjusting from the factory
settings may cause undesired temperature in
the refrigerator section.
13. ADJUST DEFROST DURATION — 0 TO 99
MINUTES
The length of the defrost can be adjusted 0 to 99
minutes long. The other defrost parameters still
apply. Lengthening a defrost may cause higher

Thermistors
1000 Series Self Preservation Mode:
Thermistors are used for various temperature readings.
minutes.
The unit will cycle on for 10 minutes then off for 40
Thermistors provide reliable temperature readings using a
resistance which varies based on surrounding
temperatures. If a faulty thermistor is suspected it may
be tested using an accurate ohmmeter.
Both thermistors in the unit are identical. If a thermistor is
suspected of being defective, the resistance can be
verified. Place the thermistor in an ice water bath, the
resistance should read 16.1k OHMs +/-5% on your meter.
Evaporator Thermistor
If the evaporator thermistor fails, the unit will rely on a
preset defrost timer during defrost cycles. The unit will
otherwise operate normally. Refer to defrost section.
