NOTE
The roof air conditioner can lower the temperature within the vehicle to a certain level.
The temperature depends on the type of vehicle, the ambient temperature and the
cooling capacity of your roof air conditioner.
Below an outer temperature of 16 °C the roof air conditioner doesn't cool anymore. In
this case only use the air conditioning mode "Circulating air" (
The roof air conditioner is protected against over-voltage. When the supply voltage is above 265 V, the roof air
conditioner stops working. It resumes normal service when the supply voltage is within the allowed range.
7.1 Components
The refrigerant circuit of the roof air conditioner consists of the following main components (fig. 1, page 3):
• Compressor (1)
The compressor draws in the refrigerant used and compresses it. This raises the pressure and therefore the tem-
perature of the refrigerant.
• Condenser (2)
The built-in liquefier works like a cooler or heat exchanger. The air flowing past absorbs the heat and the hot
refrigerant gas cools down and becomes liquid.
• Evaporator (3)
The evaporators cool down and dehumidify the air flowing past them. The refrigerant absorbs the heat and
vaporises.
