Filter Cartridge Replacement
Filter cartridge change as follows:
• Open the condensate valve of the final filter housing until it's depressurized (Fig.1)
• Unscrew filter housing cover by using the special filter tool (Fig.2)
• Place the T-piece end of the filter tool in the recess of the filter cartridge (Fig.3)
• Unscrew the filter cartridge anti-clockwise and pull the cartridge out of the housing (Fig.4)
• Open the packing of the new filter cartridge and place it with the filter tool in the filter housing
• Screw the new filter cartridge hand tight in by using the filter tool
• Screw the cover of the filter housing first manually in
• After it has been completely screwed in, turn cover anticlockwise for 90°. This avoids tightening
of the cover due to vibration
The filter cartridge change is now completed.
Note
Ensure that the old filter cartridge is disposed correctly at an approved waste point.
