Installation Manual 10WARNING: The rear of the refrigerator cooling systemhas hot surfaces and sharp surfaces that can damageelectrical wiring. Make sure that there is a good clearancebetween all electrical wiring and the cooling system ofthe refrigerator. Position any electrical wiring within therefrigerator enclosure opposite the burner side of therefrigerator. Do not put any electrical wiring through theroof exhaust vent. Failure to correctly position electricalwiring can result in electrical shock or fire.Connect the 120 volts AC supply:WARNING: Connect the AC power cord(s) only to agrounded three-prong receptacle. Do not remove theround ground prong from any of the AC power cords. Donot use a two prong adapter or an extension cord withany of the AC power cords. Operation of the refrigeratorwithout correct ground can cause dangerous electricalshock or death if you are touching the metal parts of therefrigerator.Put the AC power cord(s) into a grounded three-prong receptacle:- Make sure the receptacle is positioned within easy reach ofthe lower intake vent.- Make sure the power cord(s) does not touch the burnercover, the flue pipe, or any hot component that coulddamage the insulation of the power cord.Connect the 12 volts DC supply:As the distance from the vehicle battery to the refrigeratorincreases, the correct AWG wire size and fuse size alsoincreases. If the wire size is too small for the distance, a voltagedrop occurs. The voltage drop decreases the output of thesystem heater and causes poor cooling performance.1. Determine the min. wire size and the max. fuse size to use:WARNING: If you use an incorrect wire size and/or fusesize, electrical fire can result.- On 2-way models, use a minimum of 18 AWG wire and amaximum 6 Amp fuse.- On 3-way models, measure the distance from the vehiclebattery to the refrigerator.- If the distance is 0 - 20 feet, use a minimum of 10 AWGwire and a maximum 30 Amp fuse.- If the distance is over 20 feet, use a minimum of 8 AWGwire and a maximum 40 Amp fuse.- If the wire size is larger than the min. size, use the correctfuse per RVIA A119.2 standard or local codes.Connect the Propane Gas ComponentsThis refrigerator operates on propane gas at a pressure of 11inches Water Column Propane.The controls operate on 12 volts DC (10.5 volts min. - 15.4 voltsmax.). Operation out of these limits can damage the refrigeratorelectrical circuit parts and will void the warranty.Connect the propane gas supply system:WARNING: Be very careful when working on or near thepropane gas system.- Do not smoke, or use an open flame near the propanegas system.- Do not use an open flame to examine for leaks.- Do not connect the refrigerator to the propane gas tankwithout a pressure regulator between them.- To avoid a propane gas leak, always use two wrenchesto tighten or loosen the propane gas supply lineconnections.- Leaking propane gas leak can ignite or explode andresult in dangerous personal injury or death.Connect the gas supply line to the refrigerator:- Make sure that all tubing and fittings obey all local, state, andnational codes about size and type.2. Install a fuse in DC power supply wires between the batteryand the refrigerator:- Put fuse as close to the battery as possible.3. Connect the DC power supply wires (See Art00966):- Attach a 1/4 inch Quick Connect terminal to each DC powersupply wire.NOTE: Do not use the chassis of the refrigerator or the vehicleframe as one of the conductors. Attach the DC powersupply wires only to the battery and the power board[49] of the refrigerator.- Push the positive DC power wire [50] onto the power boardterminal that is marked 12VDC.- Push the DC ground wire [51] onto the power board terminalthat is marked GND.- Make sure each DC power supply wire is on the correctpolarity terminal.!!!!
