Important: Before operating the Parked HVAC system, make sure that the intake and outlet vents for the A/C and heater units are clear. Blocked vents will hamper the operation of the unit.

The control panel for the parked A/C and heater is located on the back wall of the sleeper near the left side. It has a temperature control dial, and a four-position mode selector switch. Turn the temperature control dial to the left for cooling, and to the right for heat. See Fig.. See Table. for a description of the function of the mode switch.

The system must be turned off whenever it is not in use, or the batteries may not charge properly. After using the system, turn the mode switch to the OFF position, even if the unit is not running.
