Environmental Requirements
u-line.com
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 & PRODUCT DIMENSIONS for recommended
receptacle location.

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.

LEVELING INFORMATION
1. Use a level to
conrm the unit is
level. Level should
be placed along top
edge and side edge
as shown.
2. If the unit is not level, adjust the legs on the corners of
the unit as necessary.
3. Conrm the unit is level after each adjustment and
repeat the previous steps as needed.
INSTALLATION TIP
If the room oor is higher than the oor in the cutout
opening, adjust the rear legs to achieve a total unit rear
height of 1⁄8” (3 mm) less than 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.
INSTALLATION
1. Plug in the power/electrical cord.
2. Gently push the unit into position. Be careful not
to entangle the cord or water and drain lines, if
applicable.
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 interior packing material and wipe out the
inside of the unit with a clean, water-dampened cloth.

Door Swing
For Integrated models that are installed adjacent to a wall,
1/2" (13 mm) clearance is recommended from wall on
hinge side to allow the door to open 90°. Allow for
additional space for any knobs or pulls installed on the
integrated panel/frame.

DOOR ALIGNMENT AND ADJUSTMENT
Align and adjust the door if it is not level or 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
rmly in contact with the cabinet all the way
around the door (no gaps). Carefully examine the
door’s gasket to ensure that it is rmly in contact
with the cabinet. Also make sure the door gasket
is not pinched on the hinge side of the door.
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 both the upper and lower hinge plates.
3. Square and align door as necessary.
4. Tighten Torx head screws on hinge.
5. Reinstall gasket into the channel starting at the corner.
REVERSING THE DOOR
1. Open door.
2. Using T-25 Torx bit loosen screw #1 and remove screw
#2 on top and bottom hinge. Slide and remove the
door from the unit.
Note: One hinge includes a metal spacer. Spacer
must be used with that hinge when reversing the
door.
3. Remove caps from screw heads on opposite side (2 on
top and 2 on bottom). Using #2 Phillips bit, remove
the 4 underlying screws. Reinstall the screws and caps
on the opposite side.
4. Partially install screw #1 in the outer most holes on
top and bottom. Rotate door 180o, align hinge over
screw #1 and slide/seat into position. Reinstall screw
#2 on top and bottom. Tighten both screws and install
hinge cover.

Cleaning
Stainless Models
Stainless door panels and handles can discolor when
exposed to chlorine gas, pool chemicals, saltwater or
cleaners with bleach.
Keep your stainless unit looking new by cleaning with a
good quality all-in-one stainless steel cleaner and polish
monthly. For best results use Claire® Stainless Steel
Polish and Cleaner. Comparable products are acceptable.
Frequent cleaning will remove surface contamination that
could lead to rust. Some installations may require cleaning
weekly.
Do not clean with steel wool pads.
Do not use stainless steel cleaners or polishes on
any glass surfaces.
Clean any glass surfaces with a non-chlorine glass
cleaner.
Do not use cleaners not specifically intended for
stainless steel on stainless steel surfaces (this
includes glass, tile and counter cleaners).
If any surface discoloring or rusting appears, clean it
quickly with Bon-Ami® or Barkeepers Friend Cleanser®
and a nonabrasive cloth. Always clean with the grain.
Always finish with Claire® Stainless Steel Polish and
Cleaner or comparable product to prevent further
problems.
Using abrasive pads such as Scotchbrite™ will
cause the graining in the stainless steel to
become blurred.
Rust not cleaned up promptly can penetrate the
surface of the stainless steel and complete
removal of the rust may not be possible.
Integrated Models
To clean integrated panels, use household cleaner per the
cabinet manufacturer’s recommendation.
INTERIOR CLEANING
Disconnect power to the unit.
Clean the interior and all removed components using a
mild nonabrasive detergent and warm water solution
applied with a soft sponge or non-abrasive cloth.
Rinse the interior using a soft sponge and clean water.
Do not use any solvent-based or abrasive
cleaners. These types of cleaners may transfer taste to
the interior products and damage or discolor the lining.
DEFROSTING
Under normal conditions this unit does not require manual
defrosting. Minor frost on the rear wall or visible through
the evaporator plate vents is normal and will melt during
each off cycle.
If there is excessive build-up of 1/4" (6 mm) or more,
manually defrost the unit.
Ensure the door is closing and sealing properly.
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.
