2.4 Extractor, filler and measurement valves
for quick couplings of the AC service
station on the refrigerant circuit
WARNING
Before removing the extractor and filler valves, the refrigerant
must be drained off with the aid of the A/C service station.
If the refrigerant circuit is not opened within 10 minutes after
draining it off, pressure can arise in the refrigerant circuit due
to the post-evaporation. Drain the refrigerant once again.
Note
Only use valves and connections that are resistant to refrig‐
♦
erant R134a and related refrigerant oils.
Different connections (outside diameter) for the high-pressure
♦
and low-pressure side guarantee that the quick-coupling
adapters are not interchanged.
Carefully screw in the handwheel of the service coupling after
♦
connecting the A/C service station and only so far until the
valve of the service connection is safely opened (observe the
pressure gauge, do not over-press the valve).
After disconnecting the quick-coupling adapter tighten the
♦
caps to prevent any dirt from penetrating.
Special tools and workshop equipment required
♦ Socket inserts -T10364-
