W A R N I N G
Possible death or severe injury from hazardous electrical voltage!
► Prior to reaching into the water, isolate (switch off and disconnect) all units/devices used in the water.
► Isolate the device (disconnect from the power supply) before carrying out any work on it.
8.1 Cleaning the unit
► Do not use aggressive cleaning agents or chemical solutions as they could attack the housing or
impair the function of the unit.
► Recommended cleaning agent for removing stubborn limescale deposits:
– Pump cleaning agent PumpClean from OASE.
– Vinegar- and chlorine-free household cleaning agent.
► After cleaning, thoroughly rinse all parts in clean water.
8.2 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 error messages. ( → Error 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)
► Check the water level at the water level indicator on the inner cover.
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.
8.3 Cleaning foam filters
► When the water reaches the 100 % mark of the water level indicator, it is necessary to clean the foam
filters.
► Do not use any chemical cleaning agents as they would kill the filter bacteria.
Prerequisite
► The filter pump is switched off.
► All other electrical units of the filter system are switched off (e.g. UVC clarifier).
► The water level in the filter system has dropped by approx. 10 cm.
How to proceed:

N
1. Pull up the foam holders five or six times.
– This will compress the foam filters, washing out the dirt.
2. Open the DN 75 dirt outlet and allow the dirty water to drain out completely.
3. Rinse the container with running water. Then close the DN 75 dirt outlet.
4. Start up the unit again.
5. Repeat the process if the water is still above 25 % on the water level indicator.
