B101Information About Electrical ConnectionElectrical Connection120 Volts AC-400 SeriesThe refrigerator is equipped witha three prong plug for protectionagainst shock hazard and must beconnected into a recognized threeprong attachment receptacle. Thefree length of cord is 24", so it isrecommended that the receptaclebe located to the left side of the refrigerator(viewed from rear) andapproximately 12" from the floor.This allows easy accessibilitythrough the vent door. The cordmust be routed so as not to comein contact with the burner cover, fluepipe or any other component thatcould damage the cord insulation.WARNINGDO NOT REMOVE (CUT) GROUND-ING PRONG FROM THE REFRIG-ERATOR AC POWER CORD. RE-MOVAL OF THIS PRONG CAN RE-SULT IN A SEVERE ELECTRICALSHOCK, AS WELL AS VOIDING THEREFRIGERATOR ELECTRICAL CER-TIFICATION AND WARRANTY.12 Volts DC Connection -400 SeriesThe 12 volt DC supply is necessaryfor the flame ignition circuit inthe gas mode, the interior light, humidityheater, and to supply powerfor 3-Way models in the DC mode.The AC mode (2-Way or 3-Waymodels) operates independently ofthe 12 volt DC. The DC supplyconnections are made at the terminalblock provided at the rear ofthe refrigerator. The terminal blockaccepts wire connections with 1/4"Quick Connect terminals. Correctpolarity must be observed whenconnecting to the DC supply. Thedistance the current must travelfrom the battery to the refrigeratordictates the AWG wire size to be used. Should the wire be too small for thedistance, a voltage drop will result. In case of 3-Way models, the voltagedrop affects the wattage output of the cartridge heater and resultant refrigeratorperformance.OPERATIONModels 442-443-452-453-462-463-482-483All use a single combination control to determine and regulate the mode ofoperation (LP GAS or Electric). The control is operated by two knobs, thefirst to select the mode of operation (LP GAS or Electric); the second, tocontrol the thermostat setting. The control consists of a gas shut off valve,safety valve, thermostat and electric interlock. The interlock prevents thepossibility of running on LP GAS and Electric at the same time. The safetyvalve is built into the combination control, and is designed so that any loss offlame will stop the gas flow to the burner. It is controlled by means of a thermocouplepositioned in the gas flame. As long as a flame is detected by the thermocouple,the valve will remain open. In the event of flame failure, the valvecloses, shutting off the gas flow. To light or relight the burner, the gas controlknob must be depressed or held in until the relighter establishes a flame. Therelighter is made active by means of an illuminated rocker switch. When the relighterswitch is in the on position it will illuminate, signaling that 12VDC is presentand energizing the relighter to send a spark to the burner. It will continueto spark until either a flame has been established or the switch is turned off.On the 3-Way models (A/C, D/C and LP Operation), there is an A/C-D/C selectorswitch. To operate the refrigerator on 120VAC, set the mode selectorto ELEC and depress the A/C switch. If 120VAC is available, the refrigeratorwill function on A/C current. To operate the refrigerator on D/C Electric whiletraveling, leave the mode selector switch in ELEC position, and depress theD/C switch for DC operation.Electrical Connection - 12 Volt DC12 volt DC must be connected (see Figure 3.1 below) at all times in orderto operate the electronic ignition system, and the interior light and high humiditycircuit.The 12 volt DC power source can be either a 12 volt "deep cycle battery" orthe vehicle’s convertor.
