Painting Vehicles with A/C
When performing paint work repairs, object temperatures of 80°
C are not to be exceeded in drying booths or their pre-heating
areas.
Reason:
Exposure to heat creates considerable pressure in the system,
which could cause it to burst.

Refrigerant Circuit, Draining
Refrigerant is never to be allowed to escape into the atmosphere,
but rather it is to be extracted from the refrigerant circuit using an
extractor or A/C service station. The drained refrigerant will be
locally recycled or is send to an environment-recycling place to
the manufacturer (different or additional laws may apply in indi‐
vidual companies). Transfer the vehicle to a workshop that has
the necessary tools and equipment and where the work can be
performed by qualified personnel. Refer to ⇒ Refrigerant R134a
