Installation
N.B.: before carrying out any work or maintenance on your aquarium, disconnect all electrical
appliances installed inside or outside of it. Check that the voltage indicated on the product
corresponds to that of your power supply network. The Professional lter should be below the
level of the aquarium when it is primed (g. 1).
If you wish to position it at the side, you must do so only once the lter has begun functioning.
Preparation of the lter

• Mount the pre-lter grid onto the suction unit.
• Choose the position you consider most appropriate for the suction unit, using the clips with
suction caps (g. 3).
• Assemble the delivery unit and choose a position for it, if possible at a distance from the suction
unit, in order to ensure eective recirculation (g.4).
• If you wish, you may apply the perforated bar to improve oxygenation at a 90° angle (g.4 -5),
positioning it all in the aquarium at the surface of the water (g.6).
• Cut the exible tubes to the length required to ensure the water runs through as straight as
possible, so as to prevent possible (g.7) obstruction of the exible tubes (g. 20).
