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.

! 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.

INSTALLATION TIP
If the room floor is higher than the floor in the cutout opening, adjust the rear legs to achieve a total unit rear 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. Adjust the front legs to level the unit after it is correctly positioned in the opening.

Door Stop
Your U-Line unit was shipped to you with the optional 90° pin.
Your unit’s door(s) will open 115° straight from the factory. If you would like the door stop at 90° follow these instructions.

Door Adjustments
DOOR ALIGNMENT AND ADJUSTMENT
Align and adjust the door if it is not level or is not sealing properly. If the door is not sealed, the unit may not cool properly, or excessive frost or condensation may form in the interior.
NOTICE
Properly aligned, the door’s gasket should be firmly in contact with the cabinet all the way around the door (no gaps). Carefully examine the door’s gasket to ensure that it is firmly in contact with the cabinet. Also make sure the door gasket is not pinched on the hinge side of the door.
! CAUTION
Do not attempt to use the door to raise or pivot your unit. This would put excessive stress on the hinge system.
Alignment and Adjustment Procedure
1.Open door and remove gasket near the hinges.
2.Using a T-25 Torx Bit, loosen each pair of Torx head screws on both the upper and lower hinge plates.
