Refrigerant Circuit

Refrigerant Circuit

Special tools, testers and auxiliary items required

• Torque wrench (V.A.G 1331/) (5 to 50 Nm)

• drip tray for shop crane (VAS 6208)

• Hose clamps up to dia. 40 mm (3093)

• A/C service station (VAS 6007A) or succeeding model.

• Refrigerant must be extracted before hand using e.g. A/C service station (VAS 6007A).

• The previously used service stations can still be used => catalog V.A.G tools.

• To prevent the ingress of dampness all components of the refrigerant circuit which have been opened must be sealed with suitable plugs.

• The color coding of O-rings for the R134a refrigerant circuits has been discontinued. Colored and black O-rings are used.

• Under certain conditions, fluid reservoir with dryer is no longer to be replaced after each time the refrigerant circuit is opened. In ELSA, see Heating/Ventilation/Air Conditioning; Air Conditioning with R134a Refrigerant; Replacing Components.

• Information for repairing vehicles with air conditioning and working with refrigerant can be found in ELSA under Heating-Ventilation-Air Conditioning; Air Conditioning with R134a Refrigerant; Technical Data.

CAUTION!
There is a danger of ice-up.

Refrigerant leaks out if refrigerant circuit is not discharged.

Refrigerant must be extracted before opening refrigerant circuit. If refrigerant circuit is not opened within 10 minutes of extraction, pressure may form in refrigerant circuit due to evaporation. Extract refrigerant once more.





1 Fluid reservoir with drier

• Under certain conditions, fluid reservoir with dryer is no longer to be replaced after each time the refrigerant circuit is opened. In ELSA, see Heating/Ventilation/Air Conditioning; Air Conditioning with R134a Refrigerant; Replacing Components.
