Installation Manual 8Connect the gas supply line to the refrigerator:- Make sure that all tubing and fittings obey all local, state,and national codes about size and type.- Make sure that all flexible metal connectors obey the currentCAN1-6.10 Standard.- Use 3/8” diameter copper tubing as the propane gas supplyline and use a 3/8” SAE (UNF5/8 -18) male flare fitting asthe connection to the refrigerator.- Put the propane gas supply line up through the floor of theenclosure.- Make sure the hole through the floor is large enough allowclearance for the gas supply line.- Put a weather resistant seal (grommet, sealant, etc.)around the gas supply line where it goes through the floorto prevent vibration and abrasion.- To prevent vibration and abrasion, make sure that the gassupply line is not against anything in the enclosure.- Attach the gas supply line to the bulkhead fitting of therefrigerator.Examine the propane gas supply line for leaks:WARNING: Do not allow the leak detecting solution totouch the electrical components. Many liquids areelectrically conductive and can cause electrical shortsand in some cases, fire.Use a leak detecting solution to examine the gas supply lineand all propane gas connections for leaks.If you use compressed air for the test:- The pressure of the compressed air at the manual shut offvalve of the refrigerator must not be more than 1/2 psig (14inches Water Column).- If the pressure of the compressed air is more than 1/2 psig(14 inches Water Column), remove the gas supply linefrom the bulkhead fitting of the refrigerator before the test.- If the pressure of the compressed air is equal to or lessthan 1/2 psig (14 inches Water Column), close the manualshut off valve of the refrigerator before the test.Connect the Propane Gas ComponentsPropane Gas OperationPropane gas(11 inches water column pressure)12 volts DC control voltage(10.5 volts min. - 15.4 volts max.).This refrigerator operates on these energy sources. Operationout of these limits can damage the refrigerator electrical circuitparts and will void the warrantyConnect the propane gas supply system:WARNING: Be very careful when working on or nearthe propane 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 twowrenches to tighten or loosen the propane gas supplyline connections.- Leaking propane gas can ignite or explode and resultin dangerous personal injury or death.NOTE: Do not use the chassis of the refrigerator or thevehicle frame as one of the conductors. Attach theDC power supply wires only to the battery and thepower board [1] of the refrigerator.- Push the positive DC power wire [2] onto the power boardterminal that is marked 12VDC.- Push the DC ground wire [3] onto the power board terminalthat is marked GND1 .- Make sure each DC power supply wire is on the correctpolarity terminal.
