Maintenance and cleaning
WARNING
Serious injury or death from electric shock is possible.
Disconnect all electrical devices in the water from the power supply before reaching into the wa-
ter.
Disconnect the device from the power supply before starting work on the unit.
CAUTION
Risk of injury due to sharp-edged components.
Proceed with caution during any work on the filter container to prevent injuries caused by sharp-
edged components.
Cleaning the unit
• Do not use aggressive cleaning agents or chemical solutions as they could damage 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.
Regular tasks
The filter system is self-cleaning. Carry out the following work regularly to ensure the optimum clean-
ing 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 soil-
ing (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 slide valve for the dirt outlet (at the bottom of the container) once a month for 10 sec-
onds.
• Remove accumulated dirt in front of the filter drum.
• Remove string algae from the dirt channel.
• Remove accumulated dirt from the level detection device.
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. Open the slide valve for the dirt outlet at the bottom of the container and dispose of the soiled
water in a permissible way.
4. Carry out cleaning measures.
– Rinse the Hel-X bio-elements in the container with running water.
5. Close the slide valve (dirt outlet).
6. Start up the filter system again. (→ Commissioning/start-up)
