Owner’s Manual 10Over heating shut-off device operation:Operating the refrigerator in high ambient temperatures can over heat the cooling unit and cause premature failure of the compressor(See the label inside the refrigerator).To protect the cooling unit from over heating, the refrigerator will automatically shut-off when the temperature of the power module is higherthan 212° F (100° C). The refrigerator will not restart until the temperature of the power module is lower than 176° F. (80° C).Low voltage protection system:In order to prevent completely draining the battery, the refrigerator will automatically shut-off when the DC supply voltage becomes toolow. The refrigerator will not restart until the DC supply voltages increases. These shut-off and restart voltage levels are:12VDC OperationShut-off 10.4 VDCRestart 11.7 VDCOver current protection system:Your refrigerator has an over current protection system in the electronic circuit to prevent damage to the inverter which may occur dueto a reverse polarity connection.If the refrigerator does not operate and the blue power light does not come on, check the fuse, which is located in-line with the DCconnector, and the polarity of the DC power supply. If the refrigerator still does not operate, another problem can exist in the powermodule. Have an authorized Norcold Service Center check the refrigerator.Read and understand the following maintenance sections of this manual.Norcold is not responsible for installation, adjustment, alteration, service, or maintenance performed byanyone other than an authorized Norcold Service Center.Have an authorized Norcold Service Center do these annual safety and maintenance checks:- Make sure the DC voltages are correct (See the “Electrical current necessary” section).- The 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 decrease the cooling performance of the refrigerator.Disconnect the positive (+) DC power supply wire from the battery before you do a “fast charge” of thebattery. Failure to disconnect the positive (+) power supply wire from the battery during a “fast charge” cancause damage to the refrigerator or other 12 volt DC appliances.- Make sure the area at the rear of the refrigerator is free of anything, especially combustible materials, gasoline, and otherflammable vapors and liquids.You may purchase replacement parts through your dealer or an authorized Norcold Service Center.If the supply cord is damaged, it must be replaced by the manufacturer, its service agent or similarly qualifiedpersons in order to avoid a hazard.- The LED lamps can only be replaced by the manufacturer, together with part of the appliance.Refrigerator Maintenance ChecklistNOTICECAUTION!Replacement PartsCAUTION!
