A/C service station VAS 6007A (and other or currently available service stations)
Catalog workshop equipment
- The operations "testing, extraction (recycling), evacuation and charging" are to be performed in line with the relevant operating instructions.
- The filters and dryers installed are to be replaced at the latest at the end of the period of use specified in the operating instructions and whenever the station has been drained (keep replacement filter to hand; available from equipment manufacturer, refer to operating instructions).
- Use can also be made of service stations not described here.
Catalog workshop equipment
NOTE:
- This service station comprises the following standard components: Charging cylinder, pressure gauge set, vacuum pump, shutoff valves and charging hoses.
- One quick-release coupling each (for service connections on high and low-pressure side) is included in the scope of delivery of this service station.
