Refrigerant Circuit Components

Refrigerant Circuit Components

Special tools, testers and auxiliary items required

• Drip Tray For Shop Crane (VAS 6208)

• Hose Clamps Up To Diameter 40 Mm (3093)

• Robinair A/C Service Unit (ROB 134APF) or equivalent

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

• Refrigerant must be extracted before hand using e.g. (ROB 134APF).

• The previously used service stations can still be used. Refer to V.A.G workshop equipment catalog.

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

• The color coding of refrigerant circuit O-rings with R134a 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.

There is a danger of ice-up.

Refrigerant leaks out if refrigerant circuit is not discharged.

Refrigerant must be extracted before opening the 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.
