Refrigerant: Service and Repair

Evacuating and Charging Valve, Low and High Pressure Sides

Special tools, testers and auxiliary items required

• Torque Wrench (V.A.G 1783)

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

• Ratchet Insert 1/4 (VAS 6234)

• Adapter Set With Service Connection (T10364)


There is a danger of ice-up.

Refrigerant and refrigerant oil will leak out if the refrigerant circuit has not been evacuated.

Refrigerant must be extracted before opening the refrigerant circuit. If the refrigerant circuit is not opened within 10 minutes after extracting it, pressure may build up in the circuit again. Extract refrigerant once more.

- Evacuate the refrigerant circuit using, for example, (ROB 134APF) then replace the valve - 2 -.






• Environmentally hazardous draining of refrigerant is an offense punishable by law.

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

- Remove the cap - 3 -.

- Remove the valve insert - 2 - (2.4 ± 0.2 Nm) with the (T10364) - 4 - from the refrigerant line- 1 -.
