ENSURING YOUR WARRANTY STAYS VALID
CLEANING AND MAINTENANCE
• Clean the Condenser Every Six Months
Failure to keep the condenser clean can result in permanent damage to the compressor.
The condenser coil is located near the compressor and usually at the bottom of the machine. In order for the condenser to perform
eciently, it must be cleaned about every six months to remove dust and debris and prevent overheating.
• Deep Clean the Ice Machine Every Six Months
Neglecting this cleaning will lead to mold or mildew buildup, cloudy ice, reduced water ow, reduced ice production,
and damage to the machine.
Use only manufacturer-approved, nickel-safe ice machine cleaner and follow all label warnings and
directions. Order ice machine cleaner online: www.u-line.com.
Every six months the ice machine requires a thorough cleaning to remove debris from the bin and ush out impurities that accumulates
from the water supply; clear, craft, and nugget machines are equipped with a built-in cleaning cycle.
• Clean Stainless Steel Surfaces
Your machine is built with quality stainless steel, but it can still rust when not properly maintained.
- Avoid exposure to outdoor elements such as rain, snow, sprinklers or pool splash.
- Use only a non-chlorine, non-abrasive stainless steel cleaner.
- Inspect the machine for any signs of rust. When spotted early, the rust is only on the surface and can usually be scrubbed o.
SAFE INSTALLATION AND MAINTENANCE
• Outdoor Operation
Only machines designed for outdoor use may be operated outdoors.
- The machine should be installed under cover, to avoid exposure to rain, snow, and direct sun.
- The machine should not be not be exposed to chlorinated water such as from pool or hot tub splash.
- Do not operate in temperatures below 45°F (7°C) or above 100°F (38°C).
• Indoor Operation
- Install where the machine will not be exposed to direct sunlight - especially if the appliance a glass door.
- Do not install the machine where it will be exposed to chlorinated water such as from an indoor pool or hot tub splash.
- Do not operate in temperatures below 50°F (10°C) or above 100°F (38°C).
• Location and Ventilation
- Do not block the grille on the front base of the machine; proper airow is essential to cooling.
- Do not operate the appliance inside a cabinet; it has been designed to operate under a counter or free-standing (certain models only).
• Proper Sealing - Beverage Dispensers
- If not sealed properly, excessive condensation, limited cooling, and damage to the machine will occur. When correctly installed, the
insulation should extend from within the refrigerator, through the counter, and into the tap tower.
ELECTRICAL AND DRAINAGE REQUIREMENTS
• Operate With a Safe Electrical Connection
Only operate the appliance on a dedicated circuit to avoid power uctuations and overloads.
- Do not use an extension cord. Only the supplied power cord directly connected to an outlet ensures that the machine will safely receive
adequate power. Extension cords can become unplugged accidentally, overheat, or become damaged. Improper electrical connection will
void the warranty.
• Operate With Proper Drainage
If your appliance requires a drain hookup consult a plumber for proper installation. Improper drainage can cause damage to the machine
as well as its surroundings. Improper drainage will void the warranty.
