Installation Manual 11The wire connections must be clean, tight and free of corrosion. If any of these items are not correct:- A voltage drop to the refrigerator will occur.- The voltage drop will reduce the cooling performance of the refrigerator.2. Install a fuse in DC power supply wires between the battery and the refrigerator:- Put fuse as close to the battery as possible.3. Connect the DC power supply wires:- Attach a 1/4 inch female Quick Connect terminal to each DC power supply wire.Do not use the chassis of the refrigerator or the vehicle frame asone of the conductors. Attach the DC power supply wires only to thebattery and the power board [49] of the refrigerator (See Art00975).- Push the positive DC power wire onto the power board terminal that is marked12VDC.- Push the DC ground wire onto the power board terminal that is marked GND.- Make sure each DC power supply wire is on the correct polarity terminal. 49 91 Art00975165Connect the Propane Gas ComponentsThis refrigerator operates on propane gas at a pressure of 11 inches Water Column Propane.Connect the propane gas supply system:Be very careful when working on or near the propane gas system.- Do not smoke or use an open flame near the propane gas system.- Do not use an open flame to examine for leaks.- Do not connect the refrigerator to the propane gas tank without a pressure regulator between them.- To avoid a propane gas leak, always use two wrenches to tighten or loosen the gas supply line connections.- Leaking propane gas can ignite or explode and result in dangerous personal injury or death.Connect the gas supply line to the refrigerator:- Make sure all tubing and fittings obey all local, state, and national codes about size and type.- Make sure that all flexible metal connectors obey the current CAN1-6.10 Standard.- Make sure that the materials used for the gas supply line obey both the current ANSI A 119.2 (NFPA 1192) and CSA Z240Standards on Recreational Vehicles. Norcold recommends the use of 3/8 inch copper tubing as the gas supply line and requires a3/8 inch SAE (UNF 5/8-18) male flare fitting as the connection to the refrigerator.- Put the propane gas supply line up through the floor of the enclosure.- Make sure the hole through the floor is large enough to allow clearance for the gas supply line.- Put a weather resistant seal (grommet, sealant, etc.) around the gas supply line where it goes through the floor to prevent vibrationand abrasion.NOTICEWARNING!
