5. To change cartridge filter
Replace or clean the dust bag and cartridge filter at the latest
every 6 months or after approx. 25 working hours. This depends
on the amount of dust collected in the dust bag.
The extent to which fluff and dust accumulates at the cartridge filter
depends on dust type and suctioning and is quite normal.
It has hardly any effect on the suction power.
Do not fail to keep to the stipulated cleaning intervals!
Cleaning/changing the cartridge filters
• Turn off the vacuum cleaner and pull out the mains plug.
• Open the snappers at the vacuum cleaner, take out the
dust container and place under the vacuum cleaner.
• Slacken the wing nut and twist it together with the flat
washer off from the threaded rod retainer.
• Pull the cartridge filter downwards.
Pointer:
For an easier, cleaner removal of the cartridge filter we
would recommend – before removal – pulling a PE dust
bag from below over the cartridge filter. This together with
the PE dust bag is then to be fully removed downwards.
• Slip the cleaned/new cartridge filter with the flat washer
centrally onto the threaded rod retainer up to the top stop-
per.
• Secure the cartridge filter with the wing nut and the flat
washer. Hand-tighten the wing nut.
• Re-fit the emptied dust container to the vacuum cleaner
and secure in place by closing the snappers.
Important!
Do never use the vacuum system without a filter
or if the filter is damaged!
Note:
The THOMAS filter bag set can be used to dispose of the
suctioned material (special accessory).
The vacuum socket of the Centra Clean 18-451 system
may not be used in connection with with the filter bag!
