Function description
B
Path of the water: Drawn in by a pump into the pump
unit, the water flows through the filter modules, ar‐
ranged above each other in stages to form the filter
unit. Each filter module is equipped with a foam filter and/
or filter fleece (top filter module). The water en‐ters the
filter module through the inlet on the side and exits
through the small flow‐out nozzles or the central outlet,
depending on the position of the outlet control knob.
INSTALLATION AND CONNECTION
N O T E
Ensure that the pump never runs dry!
Possible consequences: The pump will be destroyed.
Protective measure: Regularly check the water level in
the aquarium.

The supplied suction cups serve for fastening the unit
to a clean, smooth surface.
Push the suction cups into the mounting holes of
the pump unit with a twisting movement.
– Pay attention to the alignment of the tab (it
should point upwards or to the side).
Fasten the unit in a corner of the aquarium: Ensure
that the flow‐out nozzles are just below the surface
of the water.
COMMISSIONING/START‐UP
D, B
• Route each power connection cable such that it
forms a drip loop.
Switching on: Connect the unit to the mains. The unit
switches on immediately. When the unit is switched
on, it takes several minutes for the air to escape from
the unit (this makes a noise).
Use the outlet control knob to determine which wa‐
ter outlet is used (central outlet or flow‐out noz‐
zles).
Switching off: Disconnect the unit from the mains.
Remedy
Check the mains voltage.
