Installing

NOTE:
- 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 there fore 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. First, open the cap on the high-pressure side and relieve the pressure from the compressor -A-.






2. Open the oil filler screw -B- on the compressor.
3. Empty approx. 80 cubic cm of refrigerant oil out of the compressor and into a measuring glass. The remaining quantity of oil (approx. 120 cubic cm) remains in the compressor.
4. Always replace the sealing ring.

Tightening torque for oil filler plug:
- M10 x 1 26 to 36 Nm (19 to 27 ft. lbs.)

5. Use fastening screws from the new compressor. Replace O-rings and wet the new rings with refrigerant oil.

Tightening torque for refrigerant line:
- M8 x 32 screws 23 Nm (17 ft. lbs.)

6. Do not remove the plugs for the lines and compressor connection until shortly before installation.
7. Install compressor with lines.
8. Engage electrical connection and install compressor with fastening screws.
9. Install expansion tank with hydraulic pump.

Tightening torque for the compressor fastening screws on the console:
- M8 screws 23 Nm (17 ft. lbs.)

Tightening torque's of the fastening screws for the belt pulley and hydraulic pump expansion tank:
- M8 screws 23 Nm (17 ft. lbs.)
- M6 screw 10 Nm (7.5 ft. lbs.)

10. Mount bell pulley for hydraulic pump and fit drive belt.
11. Install throttle body and engage frequency valve.
12. Fasten the fuel supply lines on the fuel cooler. Make sure to counter when doing this.
13. Install the pressure pipe to the throttle body and air cleaner assembly.
14. Secure the hose on the left and right on the pressure pipe.
15. Connect the battery.
16. Fill the heating/air-conditioning system with refrigerant.
