GETTING STARTED FLUVAL U1
FLOW CONTROL

2. Decide on filter placement. Allow enough space above the filter to be able to easily
open the top cover
3. Once all parts have been identified, rinse the foam in tap water before the first
installation.
4. Insert the 3 suction cups into the 3 slots on the rear of the filter. (ill. A).
5. Insert the output nozzle with venturi vent into the output on the filter body, making
sure that the vent is facing up. (ill. B).

Note: In order to have the airflow /venturi work properly, it must remain above water.
Keep this in mind when putting the filter into its final position. Turning the valve located

on the top of the venturi valve will regulate the quantity of air produced.
7. The filter can now be fitted into the aquarium. Grasp the filter by the sides and
hold it into position. When properly positioned push against the filter adhering
the 3 suction cups to the wall of the aquarium.
Note: Be sure the line cord is correctly positioned in the slots on the back side of the
filter body (ill. D).
