DC Operation Precautions (3-way models only)

This refrigerator is made to operate on DC power while your vehicle is "in transit" and AC power or propane gas sources are not
available. Operate the refrigerator on DC power only when the vehicle engine is running.
For the refrigerator to operate correctly on DC power, the battery must be maintained in a fully charged condition.
For the battery to be fully charged at all times during refrigerator operation on DC, the vehicle engine must be running and the battery
charging system must be in good operating condition.
Keep in mind the following electrical precautions for DC operation of the refrigerator:
- Good battery condition is necessary for correct DC operation.
- The capacity of the battery charging system must be more than what is necessary for the refrigerator and other DC appliances.
- While the vehicle engine is running, make sure the voltage of the DC power supply leads at the refrigerator is more than 11.5 VDC.
Owner's Manual 8
If you open the door(s) too often, the temperatures inside the freezer and fresh food compartment do not
become stable. Allow the refrigerator to operate for about one hour after each adjustment change before you
examine the contents. The number "9" is the coldest temperature setting.
