Operation

This section describes the rooftop component’s operating controls and settings.

Understanding the controls
This section describes the operating controls.

The selector switch has eight positions, including OFF, to control the fan speeds, the cooling modes, and the optional heating modes of operation. The thermostat control knob manages the compressor’s ON/OFF operation within a temperature range of approximately 65–90 °F (18–32 °C), measured at the ADB inlet.

Understanding the settings
This section describes the settings for the unit.

Cooling operation
NOTICE: Wait at least two minutes before restarting the compressor if it has been manually cycled off using the selector switch or the temperature set lever. Otherwise, the compressor will quick-cycle and could overload the compressor or supply circuit.
This section describes how to use the cooling setting to reduce heat on warm days or evenings.

1. Turn the selector control knob to one of the three positions in the blue area on the control panel.
2. Select the speed that best satisfies your needs:
   • High Cool (fan symbol) provides maximum cooling and dehumidification.
   • Medium Cool (middle position) provides normal cooling.
   • Low Cool (next to the optional Heat position) maintains the room at the current comfort level. Normally this speed is used for nighttime operation.
3. Set the thermostat at the desired temperature level.
   The compressor will cycle on and off as cooling is required to maintain the selected temperature level. The fan runs when the compressor is off to help keep the temperature uniform throughout the RV.

Heating operation (if heat strip equipped)
For the FreshJet, where the electric heat is not an option, or for other models where electric heat is not installed, skip to “Fan-only operation” on page 23.

Complete these steps to use the heat setting to remove the chill on cool days or mornings:
For heat strip-equipped models only. The heating mode will not replace a furnace for heating your RV in cold weather.

1. Turn the selector control knob to the optional Heat position. The heat strip will turn on and begin heating.
2. When the desired temperature level in the RV is reached, move the selector control knob to the OFF position or to one of the fan positions.

The thermostat does not control the fan or heater ON/OFF cycle.

Fan-only operation
This section describes how to use the fan setting to circulate the RV air without cooling or heating:

1. Turn the selector control knob to one of the three positions in the gray area on the control panel.
2. Select the fan speed that best satisfies your needs.
   • High Fan (fan symbol) provides maximum air circulation.
   • Medium Fan (middle position) provides normal air circulation.
   • Low Fan (next to the OFF position) provides low air circulation.

Controlling the airflow
Slide the lever to increase or decrease the volume of airflow entering the RV.

Maintenance

This section describes routine activities to maintain properly working system components.
The blower motor is factory-lubricated and requires no service.

Cleaning the Air filter
NOTICE: Never run the unit without the return air filter in place. Otherwise, dirt will restrict the rooftop component’s evaporator coil and may substantially degrade the performance of the unit over time.
This section describes how to maintain a clean air filter.

1. Periodically (or a minimum of every two weeks of operation) remove the return air filter located behind the return air vent grille and wash it with soap and warm water.
2. Let the filter dry completely before placing the filter back into position.

Cleaning the ADB housing
NOTICE: Never use furniture polish or scouring powders.
Clean the ADB housing and the control panel with a soft cloth dampened with a mild detergent.

Confirm the land line is properly-sized for the product’s power load.
Contact the local service center.
Frost forms on the evaporator coil, as visible through the air inlet hole with the filter removed.| The product is producing very cold output at a very low air speed.| Inspect and clean the filter.
Open the air vents and remove any obstructions.
Confirm a minimum of two distribution vents, or the quick cool vent (located in the middle of the plastic cover) and one vent, are open.
The outside temperature is relatively low.| Adjust the thermostat control knob to a warmer setting (counterclockwise).
Operate the product on any Fan Only setting until the coil is free of frost.
Contact the local service center.

Keep the windows and doors closed or minimize their use.
Avoid using heat-producing appliances inside the RV.
Operate the product in the High Fan/Cooling mode.
Start the product before the outside temperature increases.
Condensation forms on ceilings, windows, or other surfaces.2| The air contains water vapor that is below the dew point of the surface.| Keep doors and windows closed when the unit is in operation to reduce the formation of condensation.

1. For a more permanent solution to high heat gain, accessories like the Dometic outdoor patio or window awnings will reduce heat gain by removing the effects of direct sunlight.
2. During normal operation, this product is designed to remove a certain amount of moisture from the air, depending on the size of the space being conditioned. The manufacturer of this unit will not be responsible for damage caused by condensation forming on ceilings, windows, or other surfaces.
