Water Hookup
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 # ULAWATERHOOKUP. 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.

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.

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.

USER GUIDE
ICE MAKER OPERATING CYCLES (U-CO29F
MODEL)
NOTE: The refrigeration system operates independently of
the ice maker. This is a new design for U-Line. All other
U-Line ice makers use a double throw control system
where the unit is either in a freeze mode or harvest mode.
In the U-CO29F, the refrigeration system will cycle on and
off depending on the temperature of the freezer. In most
cases, this means the refrigeration system will be
operating during the ice making and harvest modes. If the
freezer control is set too warm, the refrigeration system
may cycle off during ice making mode, slowing the ice
production rate. If this happens, adjust the freezer control
colder.
Freeze Cycle
• Ice maker thermostat (located behind grille) open.
• Freezer control closed and refrigeration system is
operating.
Harvest Cycle - 1
• Ice maker thermostat closed.
• Refrigeration system operating.
• If bin arm is up, the harvest will not initiate.
• Power goes through the bin switch to the ice maker
motor and mold heater.
Harvest Cycle - 2
• Ice maker ejector blades reach 2:00 position and cam
depresses the hold switch.
• Ejector blades stall on ice and ice maker motor
pulsates until mold heater warms and ice releases.
• Refrigeration system operating.
Water Fill Cycle
• Ice maker blades reach approximately 10:00 position
and cam depresses the water fill switch.
• Power to the water valve. Ice maker mold fills.
• Refrigeration system operating.
Eject Cycle
• Ejector blades push ice into bucket and stop at 12:00
position.
• Ice maker temperature control opens.
• Refrigeration system still operating.

LIMIT SWITCH SPECIFICATIONS
• Normally closed Bi-metal switch
• Open temperature: 104°F
• Close temperature: 83°F
The function of this switch is to open in the event of an
overheating condition. This bi-metal thermostat is
normally closed and does not initiate the ice harvest
cycle. The ice harvest cycle is initiated by a double throw,
single pole temperature located remotely from the ice
maker assembly.

VIEWING ACTUAL TEMPERATURE
In viewing temperature in these modes any offsets are
taken into account. This means that if you place a therm-
istor in a known temperature, let’s say ice water, it may
not read the 32°F that you would assume. If the control
offset was preset at -3°F while you placed the thermistor
in an icebath, the actual thermistor reading when viewing
actual temperature would read 35°F. In the unit this would
cause the cabinet to push itself 3° cooler. To view pure
thermistor readings you must go into the service menu
and choose the correct option.
To view the thermistor temperature, push and release the
up and down keys. The display will show the corrected
refrigerator temperature.
