Installing Air-Conditioning Compressor

→ Do not start the engine.

→ Do not tow the vehicle.

Information 

• New compressors are pressurized and are filled with the required amount of oil for the refrigerant circuit! 
• The remaining oil quantity in the individual components must therefore be taken into account! 
• Refrigerant oil from the compressor or refrigerant oil removed by suction from a previously run air-conditioning system may no longer be used (special-category waste)! 

1. If a new compressor is installed, correct the refrigerant oil quantity in the compressor first.
2. Replace O-rings for the refrigerant lines and wet the new rings with refrigerant oil.
3. Do not remove the stoppers for the lines and compressor connection until shortly before installation.
4. Connect the lines and screw in the two fastening screws -7, 8-  . → Tightening torque: 23 Nm (17 ftlb.) → Tightening torque: 23 Nm (17 ftlb.)
