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.

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.

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 # WATERHOOKUP. The kit

includes a 10' (3 m) braided flexible water supply line and

a brass hose fitting. When using a 1/4” (6.35 mm) O.D.

soft copper supply line use the brass nut and sleeve

included with the nut.

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.

CAUTION

!

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.

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).

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.

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.

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.

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.

Troubleshooting

BEFORE CALLING FOR SERVICE

If you think your U-Line product is malfunctioning, read

the CONTROL OPERATION section to clearly understand

the function of the control.

If the problem persists, read the NORMAL OPERATING

SOUNDS and TROUBLESHOOTING GUIDE sections below

to help you quickly identify common problems and

possible causes and remedies. Most often, this will resolve

the problem without the need to call for service.

IF SERVICE IS REQUIRED

If you do not understand a troubleshooting remedy, or

your product needs service, contact U-Line Corporation

directly at +1.800.779.2547.

When you call, you will need your product Model and

Serial Numbers. This information appears on the Model

and Serial number plate located on the upper right or rear

wall of the interior of your product.

NORMAL OPERATING SOUNDS

All models incorporate rigid foam insulated cabinets to

provide high thermal efficiency and maximum sound

reduction for its internal working components. Despite this

technology, your model may make sounds that are

unfamiliar.

Normal operating sounds may be more noticeable because

of the unit’s environment. Hard surfaces such as cabinets,

wood, vinyl or tiled floors and paneled walls have a

tendency to reflect normal appliance operating noises.

Listed below are common refrigeration components with a

brief description of the normal operating sounds they

make. NOTE: Your product may not contain all the

components listed.

• Compressor: The compressor makes a hum or pulsing

sound that may be heard when it operates.

• Evaporator: Refrigerant flowing through an evaporator

may sound like boiling liquid.

• Condenser Fan: Air moving through a condenser may

be heard.

• Automatic Defrost Drain Pan: Water may be heard

dripping or running into the drain pan when the unit is

in the defrost cycle.

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.

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.

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.

• 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.
