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.

General Installation

LEVELING INFORMATION

NOTICE
Because these units do not have leveling legs, it is extremely important that they sit on a level surface. If they are not level, the ice mold will not fill evenly. Use a level to
confirm the unit is level. Level should be placed along top edge and side edge as shown.

Grille Installation
REMOVING AND INSTALLING GRILLE

WARNING
Disconnect electric power to the unit before removing the grille. When using the unit, the grille must be installed.

WARNING
DO NOT touch the condenser fins. The condenser fins are SHARP and can be easily damaged. Removing the grille

Disconnect power to the unit.
Remove control knob (4).
Loosen the two screws (1).
Remove grille (2) and grille cap (3) from unit.

Make sure grille cap (3) is behind grille in slots provided in grille before attaching grille to unit.
Align cabinet and grille holes and secure, but do not over tighten grille screws (1).
Install control knob (4) if equipped.
Reconnect power to the unit.

Door Swing
Units have a zero clearance for the door to open 90°, when installed adjacent to cabinets. Stainless Steel models require 2-1/8″ (54 mm) door clearance to accommodate the handle if installed next to a wall.

Door Latch
The door latch assembly included with your unit can be installed to prevent the door from opening when the vehicle is in motion.

To install, perform the following:

Remove the two outer most screws from the nonhinge side.
Place spacer (2) over mounting holes. Place latch (1) on top of spacer (2).
Note : Spacer (2) only required if included with unit.
Re-install the screws, but do not tighten all the way.
Verify door latch engagement and adjust as necessary.
Tighten screws

Door latch can be used to prop door open approximately 1/2” (13 mm) when unit is not in use

First Use

All U-Line controls are preset at the factory. Initial startup requires no adjustments.

NOTICE
U-Line recommends allowing the unit to run overnight before loading with product. U-Line recommends discarding the ice produced during the first 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 off:

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.

Ice

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.

ICE MAKER ADJUSTMENT

Ice Cube Thickness Adjustment
Interval – As Required On ice maker equipped models, adjust the cube size by changing water amount injected into the ice maker assembly as follows:

FIG-16

Remove the ice maker assembly cover (1).
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
Turn the adjusting screw toward the minus (-) sign (clockwise) for smaller cubes or toward the plus (+) sign (counterclockwise) for larger cubes.
Install the ice maker assembly cover

ADJUSTING ICE HARVEST

Remove the front grille (see GRILLE INSTALLATION).
Using a flat tip screwdriver, turn the adjusting screw (3) a small increment clockwise for a COLDER setting (slower ice production) or counterclockwise for a WARMER setting (faster ice production).
Reinstall the front grille (two screws).

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.

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.

NOTICE
The drain pan was not designed to capture the water created when manually defrosting. To prevent water from overflowing the drain pan and possibly damaging water sensitive flooring, the unit must be removed from cabinetry.

To defrost:

Disconnect power to the unit.
Remove all products from the interior.
Prop the door in an open position (2 in. [50 mm] minimum).
Allow the frost to melt naturally.
After the frost melts completely clean the interior and all removed components. (See INTERIOR CLEANING).
When the interior is dry, reconnect power and turn unit on.

INTERVAL – EVERY SIX MONTHS
To maintain operational efficiency, keep the front grille free of dust and lint, and clean the condenser when necessary. Depending on environmental conditions, more or less frequent cleaning may be necessary.

WARNING
Disconnect electric power to the unit before cleaning the condenser.

WARNING
DO NOT touch the condenser fins. The condenser fins are SHARP and can be easily damaged.

NOTICE
DO NOT use any type of cleaner on the condenser unit.

Remove the grille. (See GRILLE-PLINTH INSTALLATION).
