Installation and Owner’s Manual 13Connect the Electrical ComponentsAC Operation 120 volts AC voltage(108 volts min. - 132 volts max.)Current Draw 1.4 Amps at 110 Volts AC1.5 Amps at 120 Volts ACDC Operation 12 volts DC voltage(3-way models only) (11.5 volts min. - 15.4 volts max.)Current Draw 12 Amps at 12 Volts DC14 Amps at 14 Volts DCThis refrigerator operates on both AC and DC electricalsources. Operation out of these limits may damage therefrigerator’s electrical circuit parts and will void the warranty.Connect 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 correct ground can cause dangerouselectrical shock or death if you are touching the metalparts of the refrigerator.Put the AC power cord into a grounded three-prong receptacle:- Make sure the receptacle is positioned within easy reach ofthe lower intake 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 (3-way models only):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, avoltage drop occurs. The voltage drop decreases the output ofthe system heater and causes decreased cooling performance.WARNING: A circuit overload can result if the wires and/or fuses are not the correct size. Refer to your localcodes or the applicable RVIA Standards for the correctwire and fuse sizes.1. For the best performance, Norcold recommends that youuse the following wire and fuse sizes:- Measure the distance from the vehicle battery to therefrigerator:- Tighten all of the screws.- Make sure the travel latch engages the travel latch plate.- If not, loosen the screw and adjust the height of thetravel latch plate.- Tighten the screw.Connect the Propane Gas Components- If the distance is 0 - 20 feet, use #12 AWG min. wiresize and a 20 amp max. fuse.- If the distance is over 20 feet, use #10 AWG min. wiresize and a 30 amp max. fuse.The wire connections must be clean, tight and free ofcorrosion. 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 therefrigerator.The terminals for connecting the DC power supply are markedpositive (+) and negative (-) on the terminal block of the refrig-erator. Make sure that:- Each DC power supply wire is attached to the correctpolarity terminal.- The chassis or the vehicle frame is not used as one of theconductors.- The DC power supply wires including the fuses are routeddirectly from the battery to the refrigerator.2. Connect the D.C. power supply wires:- Attach a 1/4 inch Quick Connect terminal to each DC powersupply wire.- Push each power wire onto the terminal block [1] at the rearof the refrigerator (See Art00975).- Make sure each DC power supply wire is on the correctpolarity terminal.Connect the chassis ground:Connect a ground wire between the refrigerator and the vehiclechassis:- Use #8 AWG wire with a #8 ring terminal for the groundwire.- Remove the nut and washer from the grounding terminal ofthe refrigerator.- Put the ground wire, the washer, and nut on the terminal.- Tighten the nut.This 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 nearthe propane gas system.- Do not smoke or use an open flame near the propanegas system.
