DC POWER CONNECTION continued ATTENTION If a longer connection cable is necessary, the cable cross section (or gauge) must be equal to or greater than the cable sizes recom- mended on the following table. Be careful that the input voltage at the appliance does not drop below the cut-out voltage of the com- pressor.
OPERATION Your Unique fridge, like any battery-powered refrigerating appli- ance, requires different care than appliances plugged into an elec- tric utility. Prudent operation is the key to extended service. STARTING THE FRIDGE After the fridge has been properly connected to the 12 or 24 VDC power source, the compressor will automatically turn on and the cabinet will begin cooling.

OPERATION continued ADJUSTMENTS As the ambient temperature changes with the season, it may be nec- essary to adjust the thermostat to achieve the proper internal tem- perature. If the room/ambient temperature approaches the appliance’s internal operating temperature, the appliance will not function as it should.

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 pro- gressively 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.

OPERATION continued Light 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.
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 ob- structed.
