|A/C Service Station -VAS6007A- (and further or current A/C
|Refer to the Workshop Equipment Catalog.
|It is recommended to have an eye-flushing bottle
|If liquid refrigerant has come in contact with your
skin and eyes, immediately flush with cool water for 15
minutes. Afterwards instill eye drops and consult a
doctor immediately, even when the eyes are not hurting.
|The doctor must be informed that the injury was
caused by refrigerant R134a. Should refrigerant come
into contact with other parts of the body despite
compliance with safety regulations, these must likewise
be rinsed immediately for at least 15 minutes with cold
|Work on refrigerant system should only be performed
in ventilated areas (workshops). Turn on the exhaust gas
|Refrigerant must not be stored in low-lying areas
such as cellars or in their entry ways or windowsills.
|Do not attempt repair on filled air conditioning systems by
soldering, brazing or welding. This applies also for welding and
soldering work on the vehicle, in the event that parts of the
A/C system may heat up. When performing paintwork repairs, the
temperature in the drying booth or preheating zone must not
exceed 80 C (176 F).
|Exposure to heat increases the pressure in the system, which
could cause the pressure relief valve to open.
||Discharge refrigerant circuit with A/C service station.
|Always replace damaged or leaking A/C system components. Do
not attempt to repair them by soldering, brazing or welding.
|Refrigerant containers (for example, charging cylinders of
A/C service station) must never be subjected to excessive heat
or exposed to direct sunlight.
||Vessels must never be completely filled with liquid
refrigerant. Without sufficient room for expansion (gas
cushion), vessels will rupture with devastating effect in the
event of an increase in temperature. Refer to
→ Chapter "Refrigerant R134a Characteristics".
|Refrigerant is never to be transferred to systems or vessels
in which air is present.
||Evacuate systems and vessels before charging with
