On Vehicles That Have A Connection On The Low And High Pressure Side Of The Refrigerant Circuit

Service station, connecting for measurement and testing

- Switch off ignition.
- Connect service station to power supply.
- Connect quick-release coupling adapter to charging hoses of service station (handwheels not screwed in/hand shut-off valve not open).
- Switch on service station and evacuate charging hoses (only necessary if there is air in charging hoses).
- Switch off service station.
- Remove caps from service connections (with valve).
- Connection service station with service connections with quick-release coupling adapters on vehicle refrigerant circuit.
- Screw in hand-wheel of quick-release coupling adapters only until valves are definitely open at refrigerant circuit connection (observe pressure gauge, do not strain valves).
- Perform planned tests and measurements.
