Moisture reduction heaters: The refrigerator has heaters that prevent moisture from forming on the center divider between the two doors of the freezer compartment and on the movable door seal. The heaters operate only when the refrigerator is ON and the DC power is sufficient. The heater in the movable door seal also only operates when the left door of the fresh food compartment is closed.
Operating the Refrigerator Controls AC Operation 120 volts AC (108 volts min.-132 volts max.) Propane gas operation: Propane gas 12 volts DC - control voltage (11 inches water column pressure) (10.5 volts min. - 15.4 volts max.) The refrigerator operates on these energy sources. Operation out of these limits can damage the refrigerator electrical components and will void the warranty.
Automatic mode operation: When the refrigerator is in AUTO mode, it automatically uses the most efficient energy source that is available for operation. During operation, if a more efficient energy source becomes available, the refrigerator controls change from the current energy source to the more efficient energy source as follows: - The first choice is AC operation if 120 volts AC is available to the refrigerator.
- If 120 volts AC is available to the refrigerator: - The letters “AU” and then “AC” show in the center display. - After ten seconds, the “AU” and then “AC” go off and only a green power ON light remains. - This means that the refrigerator is operating on AC electric. - If 120 volts AC is not available to the refrigerator: - The letters “AU” and then “AC” show in the center display. - After five seconds, the “AU” and then “LP” show in the center display.
