Connecting With Adapter V.A.G /10 to Refrigerant Circuit

Service Station, Connecting With Adapter V.A.G /10 To Refrigerant Circuit







- Unscrew cap from connection with valve - A - (at compressor).
- Attach O-ring - B -to connection (8.9 mm; 1.8 mm).
- Screw adapter V.A.G /10 - C - to connection - B -.
- Install valve opener - D - with appropriate seal in charging hose connection.

NOTE:
- The type of valve opener - D- and seals required depends on the charging hose used (specific to manufacturer).
- The quick-release coupling adapter is not required for connection on the low-pressure side of Audi vehicles.
- Screw charging hose - E- (to service station) to adapter V.A.G/10.







- To minimize the amount of air and moisture penetrating into the charging hoses and thus into the refrigerant circuit, the charging hoses should be connected together as illustrated.

A. Charging hose to service station
B. Hand shut-off valve
C. Charging hose (short version) with valve opener for connection to adapter - D -
D. Adapter V.A.G/10
E. Charging hose (short version) with quick-release coupling adapter (for vehicles with quick-release coupling adapter on low-pressure side)

- Perform planned tests and measurements.

Service station, connecting for measurement and testing
- Switch off ignition.
- Connect service station to power supply.
- Assemble adapter set and screw to connection on low-pressure side.
- 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 hoses).
- Switch off service station.
- Unscrew cap from service connection/connection with valve (or remove low-pressure switch and jumper relevant electrical connections).
- Connect service station via service connections with quick-release coupling adapters to vehicle refrigerant circuit.
- Only screw in handwheel of quick-release coupling adapters to the extent required to reliably open valve at refrigerant circuit connection (observe pressure gauge, take care not to strain valve).
- Perform planned tests and measurements.
