Working With Service Station

On Vehicles With Connection On Low And High-pressure Side Of
Refrigerant Circuit

Service station, connecting for measurement and testing
- Switch ignition off.
- 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.
- Unscrew caps from service connections (with valve).
- Connect service station via service connections with quick-release coupling adapters to vehicle refrigerant circuit.
- Screw in handwheel of quick-release coupling adapters until valves are definitely open at refrigerant circuit connection (observe pressure gauge, do not strain valves).
- Perform planned tests and measurements.
