Page 7: Installation A Refrigerator
2. INSTALLATION A REFRIGERATOR ■ How to Install the Refrigerator. (1) Your shockproof fridge is best installed on a solid surface. (2) Be sure your fridge is not placed near a gas stove, heater or other heat-generating appliances. (3) Adequate ventilation and suitable distance from each wall (at least 150mm or more) is necessary for the maximum cooling efficiency and minimum electric current consumption for "free standing use"( see Fig.1 shown below). -
Page 8: Electric Power Sources
2. INSTALLING A REFRIGERATOR ■ Electric Power Sources Connect only to either of the following power sources: • 240V AC from wall outlet (U1D type is AC120V) • 12V or 24V DC battery. AC and DC voltages may be connected simultaneously, when AC will be automatically selected if both voltages are applied. -
Page 9: Onboard Direct Wiring With Optional Kit
2. INSTALLATION A REFRIGERATOR ■ Onboard Direct Wiring with Optional Kit Twisting lead wire To further reduce the radio interference during DC operation, twist the negative and positive cables (use separate cables) together into a spiral form, between thebattery and the DC outlet socket. Connecting refrigerator directly to battery Any switches and lead wires for other electrical equipment should not be shared with the wiring between the refrigerator and the battery. -
