N260.3, 323 12 www.norcold.comVentilationWARNING! The installed unit must be completely isolated fromthe combustion system of the refrigerator and it must have complete andunrestricted ventilation of the flue exhaust which, in gas mode, can producecarbon monoxide. The breathing of carbon monoxide fumes can causedizziness, nausea, or in extreme cases, death.Certified installation needs one lower intake vent and one upperexhaust vent. Install the vents through the side wall of the vehicleexactly as instructed in the N260.3 Installation Manual or the 323Installation Manual. Any other installation method voids both thecertification and the factory warranty of the refrigerator.The bottom of the opening for the lower intake vent, which is alsothe service access door, must be even with or immediately belowthe floor level. This allows any leaking propane gas to escape tothe outside and not to collect at floor level.CSA International certification allows the refrigerator to have zero(0) inch minimum clearance at the sides, rear, top, and bottom.While there are no maximum clearances specified for certification,the following maximum clearances are necessary for correctrefrigeration:Bottom 0 inch min. 0 inch max.Each Side 0 inch min. 1/2 inch max.Top 0 inch min. 1/4 inch max.Rear 0 inch min. 1 inch max.These clearances plus the lower and upper vents cause the naturalair draft that is necessary for good refrigeration.Cooler air goes in through the lower intake vent, goes aroundthe refrigerator coils where it removes the excess heat from therefrigerator components, and goes out through the upper exhaustvent. If this air flow is blocked or decreased, the refrigerator maynot cool correctly.Each NORCOLD® model is certified by CSA International forcorrect ventilation.!WARNING! Do not allow the leak detecting solution to touch theelectrical components. Many liquids are electrically conductive and cancause a shock hazard, electrical shorts, and in some cases fire.Leak Test - DetergentUsing a solution of liquid detergent and water:■ Examine the propane gas supply system for leaks: make surethe propane gas supply line and all gas connections have noleaks. Do not use any liquid that contains ammonia.Leak Test - Compressed AirIf you use compressed air for the test:■ The pressure of the compressed air at the 3/8 inch male flarefitting of the refrigerator must not be more than 1/2 psi (14inches Water Column).■ If the pressure of the compressed air is more than 1/2 psi (14inches Water Column), remove the gas supply line from the 3/8inch male flare fitting of the refrigerator before the test.■ If the pressure of the compressed air is equal to or less than 1/2psi (14 inches Water Column), push and turn the gas control tothe OFF ( ) position before the test.!Propane Gas ComponentsThe refrigerator operates on propane gas at a pressure of 10.5inches Water Column min. to 11.5 inches Water Column max.WARNING! Be very careful when working on or near the propanegas system.■ Do not smoke, or use an open flame near the propane gassystem.■ Do not use an open flame to examine for leaks.■ Do not connect the refrigerator to the propane gas tank withouta pressure regulator between them.■ To avoid possible propane gas leaks, always use two wrenchesto tighten or loosen the propane gas supply line connections.■ Leaking propane gas can ignite or explode and result in danger-ous personal injury or death.!Electrical Connections120 Volts AC Electrical ConnectionThe refrigerator is equipped with a three prong plug for protectionagainst shock hazard and must be connected into a recognizedthree prong attachment receptacle. The length of cord is 24”. Thecord must be routed so as not to come in contact with the burnercover, flue pipe or any other component that could damage thecord insulation.WARNING! Do not remove (cut)grounding plug from therefrigerator AC power cord. Removal of this prong can result in a severeelectrical shock, as well as voiding the refrigerator’s electrical certificationand warranty.■ Verify AC power cord is in a grounded three-prong receptacle.■ Verify receptacle is within easy reach of the lower intake vent.■ Verify power cord does not touch the burner cover, the fluepipe, or any hot component that could damage the insulation ofthe power cord.!
