9.3 Replacing the filter cartridge
After an extended operating time, the filter cartridge must be replaced with a new one.The reason for this is
the fact that the pores of the filter material will clog slowly over time and can no longer be cleaned. The filter
cartridge must be replaced when the cleaning intervals are growing disproportionately short. The rated air
volume flow for drive mode is no longer warranted.If the visual inspection in the clean air area of the device
leads to dust penetration (dust vane), this means that the wear threshold of the filter cartridge has been
reached and that replacement is also mandatory.
WARNING
• At the work it is absolutely necessary to wear personal protection equipment (single-way suits,
protecting mask and protective goggles)!
• While carrying out this work, an endangering of other persons must be ruled out!
9.4 Procedure when replacing the filter cartridge
• Switch off the device and disconnect it from the mains!
• Fasten the two latchable casters of the deduster.
• Remove the manual cleaning crank.
• Turn out the 8 screws M6 of the filter chamber cover and remove the cover.
• Remove the earthing cable from the lid of the filter cartridge.
• The filter cartridge is fastened with 3 centring mandrels. Pull out the filter cartridge via the cleaning shaft
by slight canting to overcome the resistance produced inside the filter cartridge with the 2 wipers.
The new filter cartridge is inserted in the reverse order.
Comments:
• Please observe that the felt seal attached to the crank is not damaged.
• First slightly loosen the 8 screws "crosswise", and then screw open all the way. When screwing shut,
also screw on the screws "crosswise", then screw in opposing screws tightly!
• Removal of the old and installation of the new filter cartridge should only be performed by qualified and
instructed staff.
• Visually inspect when replacing the filter chapter. In particular, observe possible dust vanes or other
damage to the cleaning shaft, rubber wipers, etc.
• The support face for the filter cartridge rubber seal must be cleaned thoroughly especially before
installation of the cartridge to prevent possible leaks.
• Dispose of the filter cartridge in a container that can be closed (e.g. plastic bag) under observation of
the already-described safety provisions and according to the local rules. Observe that a particle filter
mask P2 must be worn for the above work.
NOTICE
The vacuum line of the container to the filter chamber/raw air area of the device must be inspected for
clogging at each replacement of the dust/chip bag. Clogging of the vacuum line will lead to the dust/chip
bag being sucked into the inner area of the filter cartridge and thus to strong reduction of the volume flow or
interruption of the extraction function.
