6 Technical limits and conditions

The roof air conditioner is intended for vehicles with roofs with a thickness of 25 mm … 60 mm. The roof top air conditioner will operate ambient temperatures between -2 °C … 52 °C. The roof air conditioner is designed to be installed within ± 10 ° of the horizontal plane.

7 Technical description

The roof air conditioner supplies the vehicle’s interior with cool or warm air which is without dust and dirt and can be dehumidified.

The roof air conditioner can lower the temperature within the vehicle to a certain level that depends on the type of vehicle, the ambient temperature and the cooling capacity of the roof air conditioner. Below an outer temperature of 16 °C the roof air conditioner does not cool anymore.

The roof air conditioner is operated with the following operating elements:

• Control panel
• Remote control (only some models, see List of models on page 6)

7.4 Air conditioning modes

A

| You specify the temperature, and the roof air conditioner brings the interior to this temperature by heating or cooling and by controlling the necessary fan speed.
Cooling| | You specify the temperature and fan settings, and the roof air conditioner cools the interior to this temperature.
Heating| | You specify the temperature and fan settings, and the roof air conditioner heats the interior to this temperature. The fan will only start after 2 min (on Low speed) and then after around 5 min will go to the set fan speed (after the evaporator reaches temperature).
Ventilation| | You specify the fan settings, and the roof air conditioner circulates air without heating or cooling.
Dehumidifying| | The roof air conditioner removes moisture from the air without heating or cooling the interior thus decreasing the relative air humidity.
Air purifier| | The roof air conditioner ionizes the air, thus collecting dust and particles including to viruses and bacteria out of the air.

7.5 Additional functions

reduce the noise levels for comfortable sleeping.
I Feel| | The remote control measures the room temperature and transmits this measurement to the roof air conditioner every 10 min. The roof air conditioner adapts the target value to this measurement.
Soft start| | The peak current that the compressor start produces is reduced by the soft start function. If a generator is used as power supply, the generator will not be overloaded.

8 Before initial use

Inspection before starting up

Before switching on the roof air conditioner, observe the following:
1. Check whether the supply voltage and frequency correspond to the values specified in Technical data on page 23.
2. Ensure that both the air intake openings and the air nozzles are free. All ventilation grilles must always be kept free to ensure that the roof air conditioner is able to operate at maximum capacity.

Prepare the remote control

3. Insert the batteries (Replacing the remote control batteries on page 15).

Set the time

4. Set the current time (Setting the current time on page 13).

13 Disposal

NOTE

NOTE

Disposal refrigerant: Provide the refrigerant in the correct recovery cylinder back to the refrigerant supplier with a waste transfer bill. Do not mix refrigerants in the refrigeration systems and the cylinders.

If compressors or compressor oils are to be disposed of, ensure that the compressors have been evacuated to an acceptable level to ensure that no flammable refrigerant remains in the lubricant. To speed up the evacuation process, the compressor housing must only be heated electrically. When draining oil from a system, ensure that it does not ignite or come into contact with the ground.
