Go to the liquid propane tank on the RV and turn the valve to the right to open gas flow to the on position.
Open the refrigerator door and look for the LP./AC switch. Turn the switch to the LP setting if the RV is not plugged into electric connections.
Set the temperature for your desired setting in the refrigerator by turning the temperature setting dial to your desired setting. Close the door.
Turn the switch to AC when the RV is parked and connected to AC electric hookups. This by-passes the LP tank and powers the RV from the electric, saving the use of the LP gas.
