4.1 Faults in the air-condi-
tioning / heating system
Possible causes:
Faulty evaporator or condenser fan
Air filter and/or plate fins of condenser,
evaporator or heat exchanger fouled
or clogged
Loss of refrigerant or too little refrig-
erant in the system
Loss of coolant or too little coolant in
the system
Air in coolant circuit (bleed circuit via
bleed valve of CC8 system)
The air-conditioning system must be in-
spected by an authorized repairshop if the
air-conditioning / heating system cuts out
continuously.
4.2 Faults in the refrigerant
circuit
If faults arise in the refrigerant circuit, the
system must be inspected and repaired by
an authorized specialist repairshop. Under
no circumstances may refrigerant be dis-
charged into the atmosphere (Section 8 of
the regulation dated 6 May 1991 banning
CFCs and halones).
