8.2 Regular tasks
The filter system is self-cleaning. Carry out the following work regularly to ensure the optimum cleaning
capacity of the filter system.
Regular checks
► Check the display of the control system for any system messages. (→ System messages)
► Check the area in front of the separating plate and the inside of the filter drum for excessive soiling
(e.g. string algae). To do this, remove a screen element. (→ Removing/fitting a screen element)
Removing accumulated dirt
Dirt that cannot be collected by the filter drum, sinks to the bottom and has to be removed.
► Open the DN 75 dirt outlet for approx. 10 seconds once per month.
► Remove accumulated dirt in front of the filter drum.
► Remove string algae from the dirt channel.
► Remove accumulated dirt from the level detection device.
8.3 Cleaning the entire filter system
► The entire filter system only needs to be taken out of operation for cleaning and maintenance if it is
extremely soiled.
► Do not use any chemical cleaning agents as they would kill the filter bacteria.
How to proceed:
1. Switch off all filter pumps.
2. Switch off all other electrical units of the filter system (e.g. UVC clarifier).
3. Gravity fed systems only: Close the slide valves (supply and return) of the filters connected in series
to prevent further water flow.
4. Open the slide valve for the DN 75 dirt outlet at the bottom of the container and dispose of the soiled
water in a permissible way.
5. Carry out cleaning measures.
– Rinse the Hel-X bio-elements in the container with running water.
