Safety instructions for maintenance
If faults develop in the refrigerant circuit, the system must be tested and repaired by an authorized specialist
repairshop. Under no circumstances may refrigerant be discharged into the atmosphere (refer to Section 8
of the regulation dated 6 May 1991 banning CFCs and halones).
Never heat refrigerant cylinders with a naked flame.
Liquid refrigerant must never be allowed to come into contact with the skin.
Always wear protective clothing and goggles when handling refrigerant.
WARNING
Do not perform soldering or welding directly on components of the closed
refrigerant circuit or in its vicinity. The heating will cause a rise in the circuit
pressure. There is a danger of explosion.
Before performing any work allow the system to cool down completely. Risk
of injury due to burns on the condenser, compressor and hoses.
Installation, maintenance and repair work must be carried out by duly
qualified personnel. Such work may only be undertaken with the engine off
and the power supply switched off.
The battery must be disconnected before opening the roof-top air-
conditioner, removing the compressor or starting any work on the electrical
wiring.
Do not wear metal jewellery (bracelets, watches, necklaces, rings) when
working on the air-conditioning system.
