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.
Possible cause
Harmless food-grade oil may leak from a
new rinsing pump for a short time when first
used
Insufficient Hel-X biomedia used
Unit has only been in operation for a short
time
The meshed tube has slipped
Defective meshed tube
Aerator rod is blocked
Aerator pump malfunction
Hel-X biomedia are not yet fully colonised.
Remedy
No measure is necessary
Use more Hel-X biomedia if necessary.
The full biological cleaning effect is only achieved
after several weeks.
Correct the position of the meshed tube.
Replace the meshed tube.
Replace the aerator rod.
Check the aerator pump.
It takes several weeks for the biomedia to become
colonised by bacteria. Wait for the natural process
to take place.
