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.

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)

Storage/overwintering

Decommissioning depends on whether or not the unit is protected against freezing.
The unit is protected from frost (e.g. stored in a garage or other enclosure)
The unit can be operated as long as the water temperature does not go below +4 °C.
The unit is not protected from frost (e.g. outdoor installation)
Take the unit out of operation at water temperatures below +8° C or, at the latest, when freezing
temperatures are to be expected.
• Drain the unit as far as possible, clean thoroughly and check for damage.
• Empty all hoses, pipes and connections as far as possible.
• Leave the slide valves open.
• Cover the container so that no rain water can enter.
• Protect pipes and slide valves that are in contact with water from frost.
