Installation and Owner’s Guide 14This refrigerator operates on propane gas at a pressure of 11inches Water Column Propane.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.Connect the Propane Gas ComponentsConnect the 120 volts AC supply:WARNING: Connect the AC power cord only to agrounded three-prong receptacle. Do not remove theround ground prong from the power cord. Do not use atwo-prong adapter or an extension cord. Operation of therefrigerator without a correct ground could cause danger-ous electrical shock or death if you are touching the metalparts of the refrigerator or the vehicle.Put the AC power cord into a grounded three-prong receptacle:- Make sure the receptacle is within easy reach of the lowerintake vent.- Make sure the power cord does not touch the burner cover,the flue pipe, or any hot component that could damage theinsulation of the power cord.Connect the 12 volts DC supply (model 323 only):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 fires can result.- Measure the distance from the vehicle battery to therefrigerator:- If the distance is 0 - 20 feet, use a minimum of 12 AWGwire and a maximum 20 amp fuse.- If the distance is more than 20 feet, use a minimum of10 AWG wire and a maximum 30 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 DC negative wire from the battery to the blackDC wire on the terminal block of the refrigerator.- Connect the DC positive wire from the battery to the red DCwire on the termnal block of the refrigerator.- Install a 20 Amp in-line fuse on the DC positive wire and asnear the battery as possible, between the battery and theterminal block of the refrigerator.NOTE: This in-line fuse is necessary for added safety, eventhough the refrigerator has a DC fuse in the controlassembly.- 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 possible propane gas leaks, always use twowrenches to tighten or loosen the gas supply lineconnections.- Leaking propane gas can ignite or explode and result indangerous personal injury or death.Connect the gas supply line to the refrigerator:- Make sure all tubing and fittings obey all local, state, andnational codes about size and type.- Make sure that all flexible metal connectors obey the currentCAN 1-6.10 Standard.- Make sure that the materials used for the gas supply lineobey both the current ANSI A 119.2 (NFPA 1192) and CSAZ240 Standards on Recreational Vehicles. Norcold recom-mends the use of 3/8 inch copper tubing as the gas supplyline and requires a 3/8 inch SAE (UNF 5/8-18) male flarefitting as the 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 to allowclearance for the gas supply line.- Put a weather resistant seal (grommets, sealant, etc.)around the gas supply line where it goes through the floor toprevent 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 system for leaks:WARNING: Do not allow the leak detecting solution totouch the electrical components. Many liquids areelectrically conductive and can cause a shock hazard,electrical shorts and in some cases, fire.Use a leak detecting solution to examine the gas supply line andall propane gas connections for leaks.If you use compressed air for the test:- The pressure at the gas control of the refrigerator must notbe more than 1/2 psig (14 inches Water Column).- If the air pressure is more than 1/2 psig (14 inches WaterColumn), remove the gas supply line from the bulkheadfitting of the refrigerator before the test.- If the air pressure is equal to or less than 1/2 psig (14 inchesWater Column), turn the gas control to OFF before the test.
