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.
6. Close the slide valve (dirt outlet).
7. Start up the filter system again. (→ Commissioning/start-up)

the parts.

Decalcifying the screen elements

The error messages Er33, Er55 or an excessive rise in the frequency of cleaning cycles (counter) indicate
that there are limescale deposits on the screen elements. (→ Reading out the number of cleaning cycles)
Oase recommends that you descale the unit every two to three months as a preventative measure if the
water is very hard.
► Recommended cleaning agent for removing stubborn limescale deposits:
– Pump cleaning agent PumpClean from OASE.
– Vinegar- and chlorine-free household cleaning agent.
