USER GUIDE
Environmental Requirements 1
SAFETY • INSTALLATION & INTEGRATION • OPERATING INSTRUCTIONS • MAINTENANCE • SERVICE
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.

PREPARE SITE
Your U-Line product has been designed exclusively for a
built-in installation. When built-in, your unit does not
require additional air space for top, sides, or rear.
However, the front grille (plinth strip/base fascia) must
NOT be obstructed.
CAUTION
!
Unit can NOT be installed behind a closed cabinet
door.
U-Line products are designed and manufactured
to be installed in the specified cutout openings
shown, and variance to the floors or cabinetry
must be accounted for in your installation.

Side-by-Side Installation
OTHER SITE REQUIREMENTS
Side-by-Side Installation
Units must operate from separate, properly grounded
electrical receptacles placed according to each unit’s
electrical specifications requirements.
Cutout width for a side-by-side installation is the total of
the widths listed under Cutout Dimensions in each unit’s
Installation Guide. Each door can be opened individually
(one at a time) without interference.
However, to ensure unobstructed door swing (opening
both doors at the same time), 1/4" (6.4 mm) of space
needs to be maintained between the units.
Hinge-by-Hinge Installation (Mullion)
When installing two units hinge-by-hinge, 13/16" (22 mm)
is required for integrated models. Additional space may be
needed for any knobs, pulls or handles installed.
Stainless steel models which include the standard stainless
handle will require 4-9/16" (116 mm) to allow both doors
to open to 90° at the same time.

Anti-Tip Bracket 1
SAFETY • INSTALLATION & INTEGRATION • OPERATING INSTRUCTIONS • MAINTENANCE • SERVICE
Anti-Tip Bracket
CAUTION
!
The anti-tip bracket must be installed to prevent
the unit from tipping when doors are fully
opened or excess weight is placed on the front of
the unit.
The anti-tip bracket has multiple mounting options.
Mounting will depend on your particular cabinet
configuration. Follow the instructions below to secure the
anti-tip plate to the unit. Locate your anti-tip bracket and
5 #8x5/8" screws included with your unit.
TOP MOUNT
Top mount configurations work well with fully secured
wood or laminate countertops.
1. Align the bracket on top of your unit as shown above.
The bracket must be used to ensure a secure mount.
2. Using 2 of the supplied #8x5/8" screws, install screws
into the plate using a #2 Phillips head screwdriver.
3. Completely slide the unit into its position in the
cabinet. Be certain unit height is properly adjusted.
(See GENERAL INSTALLATION).
4. Open door completely. Make certain door clears
surrounding cabinetry.
5. Using a 3/32" drill bit, drill 3 pilot holes 5/8" (16 mm)
deep into bottom of counter top. Use the anti-tip
bracket as a template.
6. Install the 3 remaining #8x5/8" screws into the plate
using a #2 Phillips head screwdriver.
SIDE MOUNT
Side mount configurations work well if you have a granite
countertop or do not wish to mount the bracket to the
underside of your countertop.
1. Align the bracket to the hinge side of the unit as shown
above.
2. Using 2 of the supplied #8x5/8" screws, install screws
into the plate using a #2 Phillips head screwdriver.
3. Completely slide the unit into its position in the
cabinet. Be certain unit height is properly adjusted.
(See GENERAL INSTALLATION).
4. Open door completely. Make certain door clears
surrounding cabinetry.

LEVELING INFORMATION
1. Use a level to confirm
the unit is level. Level
should be placed along
top edge and side
edge as shown.
2. If the unit is not level,
remove grille and
adjust legs as
necessary.
3. Confirm the unit is level after each adjustment and
repeat the previous steps until the unit is level.
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.
INSTALLATION
1. Plug in the power/electrical cord.
2. Gently push the unit into position. Be careful not to
entangle the cord.
3. Re-check the leveling, from front to back and side to
side. Make any necessary adjustments. The unit’s top
surface should be approximately 1/8" (3 mm) below
the countertop.
4. Install the anti-tip bracket.
5. Remove the interior packing material and wipe out the
inside of the unit with a clean, water-dampened cloth.

SAFETY • INSTALLATION & INTEGRATION • OPERATING INSTRUCTIONS • MAINTENANCE • SERVICE
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.
NOTICE
If your unit is already undercounter, it will need
to be moved out to access the hinge. With the
90° stop pin in place, you will not be able to
replace the hinge cover.

2. Remove hinge cover by lifting top and bottom of hinge
cover and sliding the cover inwards to remove from
hinge.
3. Once cover is removed, slide hinge pin into hole as
shown. Pin should slide into place, stopping the door at
90°; if the pin does not go into the hole shown, hold
the door less than 90° open and try again.
4. To fully seat the pin, tap it lightly with a hammer.
5. Carefully slide your unit back in place.
NOTICE
The pin can be removed to return the door swing
back to its original 115° swing by tapping the pin
out from the bottom of the hinge.

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

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.
