Working On The Refrigerant Circuit

WARNING: This page is about a different car, the 2010 Porsche Cayenne, 2009 Porsche Cayenne, and 2008 Porsche Cayenne. However, it is still accessible from the selected car via links, so may be relevant.

WARNING: Risk of injury!

→ The leaking refrigerant is not only colourless and odourless, but is also heavier than air and therefore displaces oxygen.

→ If refrigerant gas escapes despite all safety measures having been taken, there is an undetectable risk of suffocation in poorly ventilated rooms and erection pits.

→ The gas/air mixture formed when refrigerant escapes should not be breathed in but rather extracted via suitable extraction systems (workshop extraction system).

→ No welding, soldering or hard-soldering should be carried out on any part of the filled air-conditioning system.

→ This also applies to welding and soldering work on the vehicle when there is a danger of parts of the air-conditioning system heating up.

→ The warming causes very strong overpressure in the system, which can cause the refrigerant system to burst.

Work on the refrigerant circuit should only be carried out in areas with good ventilation. There should be no erection pits, shafts or cellar stairs within a radius of 5 metres. Any extraction systems should be switched on.
