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.

Components

The refrigerant circuit of the roof air conditioner consists of the following main
components (fig. 1, page 2):
• Compressor (1)
The compressor draws in the refrigerant used and compresses it. This raises the
pressure and therefore the temperature 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.
• Blower (4)
A blower distributes the cooled air within the vehicle through an air outlet unit.
