Water Hookup
u-line.com
Water Hookup
PREPARE PLUMBING
The water valve uses a standard 1/4" (6.35 mm)
compression fitting. U-Line recommends using accessory
water hook up kit – part # 80-54674-00. The kit includes a
10' (3 m) braided flexible water supply line and a brass
hose fitting.
CAUTION
!
Plumbing installation must observe all state and
local codes. All water and drain connections
MUST BE made by a licensed/qualified plumbing
contractor. Failure to follow recommendations
and instructions may result in damage and/or
harm.
Water Supply Connection
When connecting the water supply, please note the
following:
• Before installing the unit and connecting to the cold
water supply, review the local plumbing codes.
• The water pressure should be between 20 and 120 psi
(138 and 827 kPa).
• The water line MUST have a shut-off valve in the
supply line.
• The water line should be looped into 2 coils. This will
allow the unit to be removed for cleaning and servicing.
Make certain that the tubing is not pinched or damaged
during installation.
WARNING
!
Connect to potable water supply only.
CAUTION
!
Do not use any plastic water supply line. The line
is under pressure at all times. Plastic may crack
or rupture with age and cause damage to your
home.
Do not use tape or joint compound when
attaching a braided flexible water supply line
that includes a rubber gasket. The gasket
provides an adequate seal – other materials
could cause blockage of the valve.
Failure to follow recommendations and
instructions may result in damage and/or harm,
flooding or void the product warranty.
Use new hose set. Do not reuse old hose set.
CAUTION
!
Turn off water supply and disconnect electrical
supply to unit prior to installation.
Use caution when handling back panel. The
edges could be sharp.
1. Turn off water supply and disconnect electrical supply
to product prior to attempting installation.

First Use
U-Line recommends allowing the unit to run
overnight before loading with product.
U-Line recommends discarding the ice produced
during the rst two or three hours of operation
to avoid possible dirt or scale that may dislodge
from the water line.
To turn the unit on or o:
Press the rocker switch located below the temperature
control dial in the center of the grille.
CONTROL DIAL
The control dial sets a single continuous temperature.
This set point temperature is a base setting used by the
controller to maintain the temperature zone in the unit.
The factory default MID setting, number 3 or 4 set point,
is approximately 38ºF (3ºC). The set point temperature is a
gauge for further temperature adjustments.
All U-Line controls are preset at the factory. Initial startup
requires no adjustments.

ICE MAKER OPERATION
When the ice bucket is full, the ice making mechanism will
shut off. However, the refrigeration system will continue
to cool and maintain the ice supply.
NOTICE
Do not place cans or bottles in the ice
compartment because they will freeze.
To turn off ice production: Raise the bin arm into
an upright and locked position. The unit will preserve
temperature for ice storage.
NOTICE
If not intending to use the ice maker, turn the
water supply valve off. It is also important to
raise the bin arm of the ice maker (see above).
Failure to raise the bin arm may result in damage
to the water valve.
Certain sounds are normal during the unit’s operation. You
may hear the compressor or fan motor, the water valve,
or ice dropping into the ice bucket.
CAUTION
!
NEVER use an ice pick, knife or other sharp
instrument to separate cubes. Shake the ice
bucket instead.
During periods of limited use or high ambient
temperatures, it is common for cubes to fuse together.
Gently shake the bucket to break apart cubes. If not using
the ice maker regularly, empty the ice bucket periodically
to ensure fresh cubes.
It is normal for cubes to appear cloudy. The cause is air
trapped in the water because of fast freezing. It is not
caused by the health, taste or chemical make up of the
water. It is the same air that is in every glass of water you
drink.
Remove the ice bucket for emptying and cleaning. To
remove the ice bucket, raise the bin arm and remove the
bucket from the ice compartment. Use the ice bucket for
ice storage only.

2. Find the adjusting screw on the ice maker assembly
control box (2). The adjusting screw is just below the
minus (-) and plus (+) signs on the control box.
CAUTION
!
Too large of an adjustment to the screw can
cause the water to overflow the ice maker and
can cause property damage.
3. Turn the adjusting screw toward the minus (-) sign
(clockwise) for smaller cubes or toward the plus (+)
sign (counterclockwise) for larger cubes.
4. Install the ice maker assembly cover.
ADJUSTING ICE HARVEST

Cleaning
u-line.com
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.
