OPERATION Your Unique fridge, like any battery-powered refrigerating appliance, requires different care than appliances plugged into an electric utility. Prudent operation is the key to extended service. STARTING THE FRIDGE After the fridge has been properly connected to the 24V DC power source, the compressor will automatically turn on and the cabinet will begin cooling. Allow the cabinet to cool for at least 4 hours prior to adding foodstuff.
OPERATION continued ADJUSTMENTS As the ambient temperature changes with the season, it may be necessary to adjust the thermostat to achieve the proper internal temperature. If the room/ambient temperature approaches the appliance’s internal operating temperature, the appliance will not function as it should. The appliance will tend to run colder during these conditions and it may be necessary to turn the thermostat to a warmer setting (lower number).
OPERATION continued DEFROSTING Before cleaning or repositioning the fridge, you must DISCONNECT the appliance from the electrical power supply. DEFROSTING THE UNIT The fridge compartment will become progressively covered with frost. This should be removed periodically with a plastic scraper. However, when the ice becomes very thick on the interior walls, complete defrosting should be carried out. Perform this operation when the appliance is empty and disconnected from the power supply.
OPERATION continued CLEANING Internal Cleaning Wash the inside of the appliance with luke warm water and a mild soap. Never use abrasive or corrosive cleaning agents, steel wool, scouring sponges, chemical cleaning agents, or highly perfumed cleaning products to clean the interior as these will damage the surface and leave behind a strong odor. A sponge, towel, or soft brush is recommended. Washing with a mixture of two tablespoons (30ml) of baking soda to 1 quart (1.14L) warm water.
ENERGY SAVING TIPS • Do not install the fridge close to sources of heat, such as a stove, boiler, heater, chimney, etc, and avoid exposure of the appliance to direct sunlight. • Locate the appliance in a cool well-ventilated room and make sure that the air vents of the compressor housing cover are not obstructed. Also allow adequate spacing around the cabinet for air circulation (3” or 7.5cm) • Avoid unnecessary frosting in the cabinet by packing all food and liquids in airtight packages or containers.
