Maintenance of the lter
• Always disconnect from the mains supply before carrying out any maintenance!
• Clean lter regularly, after rst installation. If your pond is heavily polluted, the lter sponge should initially be cleaned daily.
Remove the lter compartment cover (C-f) by simultaneously pressing the catch (C-g) on both sides and lifting the cover up.
• Take out the lter sponge and rinse with clean tap water.
• Activated carbon absorbs color and toxins from the water and therefore becomes saturated. Replace the lter sponge and the
lter media twice a season (more often if necessary), a Combi Clear Filter Media Set (art. 06020760 and art. 06020763) is available
from your SuperFish dealer.

Press the catch (C-h) of the front cover on both sides and lift the cover up.
• The pump and the UVC-unit are connected to each other by a 90° bend, loosen one of the swivels (D-i) to disconnect the pump
