  3. When the sleeper compartment cools to the desired temperature, turn the temperature control switch clockwise to adjust outlet air temperature. Then, turn the fan switch to adjust the air flow level.
    The system will automatically maintain the selected outlet air temperature.
  4. When air conditioning is not desired, turn the temperature control switch clockwise and turn the fan off.

    Important: To prevent the buildup of fumes or odors inside the sleeper (for example, from smoking) do not operate the heater and air conditioning system in a recirculation mode for more than 20 minutes.

    Note: Whenever the refrigerant compressor is operating, the fan will always run at a very low speed, even with the fan switch in the off position. This prevents ice from forming on the evaporator, especially during humid weather.
