7.3. Replacing the filter cartridges
Replacing the filter cartridges becomes necessary when the filter cartridges are saturated with dirt in a
manner that despite of the cleaning the filter alarm is triggered again at very short intervals or
permanently. (The filter alarm is described in chapter “Cleaning the filter cartridges”.)
Whirling up dust is possible due to the polluted filter cartridges.
The filter cartridges must be cleaned before being replaced. This is done by carrying out 3
manual cleanings via the unit control (see separate operating instructions). The filter unit
must be switched off beforehand but without disconnecting the unit from the power supply.
After the cleaning, disconnect the filter unit from the power supply and secure it against
being switched on again. After cleaning the filter cartridges wait about 5 minutes before
opening the service door of the filter housing.
For a longer service life of the filter cartridges the new filter cartridges can be pretreated with filter
aid (e.g. precoat). However, this is not necessary when using nano filter cartridges. If you wish to
precoat the new filter cartridges nevertheless, please refer to the indications in the chapter
“Precoating new filter cartridges". There you can also find a description of the operating method
of a filter aid.
● Before changing the filter cartridges hold ready an appropriate container (e.g. PE bag) for
disposal.
The polluted filter cartridges must be packed into an appropriate container
(e.g. PE bag). PE bags are optionally available (see list of spare parts)! We recommend
having disposal bags in stock.
● Open the service door of the filter cartridges. Also open the service door of the cleaning
housing. This is only possible by means of a special electrical spanner.
● Slip the disposal bag from bottom to top over the filter cartridge (A).
● Unfasten the 3 thumb screws (B) of the filter cartridge by turning them clockwise.
