Maintenance and cleaning

The filter system is self-cleaning. Dead biomass drops to the bottom and has to be removed. To do this, open
the DN 75 dirt outlet for approx. 10 seconds.
 The entire filter system only needs to be taken out of operation for cleaning and maintenance if it is ex-
tremely 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 pre-
vent 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.
6. Close the slide valve (dirt outlet).
7. Start up the filter system again. (→ Commissioning/start-up)
