  • Use a claw grip for example to pull the filter element -E- upwards out of the condenser.
  • Seal open receiver with plastic screw plug -A- to prevent ingress of dirt and moisture.

Installing

Install in reverse order of removal; note the following.

Note The screw plug, O-ring and dryer cartridge are always to be replaced after opening the receiver.

Installing

Install in reverse order of removal; note the following.

Note

  • Screw the rubber bushing of the radiator on to the lock carrier, after you have cut the fasteners -arrows- on the rubber bushing. Screws.
  • Even if fitted correctly, there may be slight pressure marks on the radiator and condenser fins. This does not mean that the components are damaged. Neither radiator nor condensers are to be replaced on account of such minor pressure marks.
  • Slight bending of the condenser (up to 4 mm) is not a problem as long as there is enough of a gap (at least 4 mm) between the condenser and the radiator, the condenser is still functioning properly and there is no leakage. If there are slight deformations, the condenser does not have to be renewed.
  • If the condenser and radiator are no longer parallel as a result of slight deformation at the securing lugs on the sides of the condenser (e.g. following an accident), this can be corrected by bending the lugs back into position, provided that the condenser is still functioning properly and that there is no leakage.

    If the lugs are slightly deformed, the condenser does not have to be renewed.
