Maintenance and 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
extremely soiled.
• Do not use any chemical cleaning agents as they would kill the filter bacteria.
7.1

Cleaning the container

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 Pond Pads in the container with running water.
6. Close the slide valve (dirt outlet).
7. Start up the filter system again. (→ Commissioning/start-up)

Replacing the aerator stone

How to proceed:
 E
1. To increase visibility of the aerator stone, remove approx. ⅔ of the Pond Pads and store in a moist
area. After completing the maintenance work, return the Pond Pads to the container.
2. Pull the aerator stone out of the clamping holder.
3. Disconnect the hose from the aerator stone and connect it to the new aerator stone.
– Fasten the connecting hose with a hose clip.
4. Push the aerator stone back into the clamping holder.
