GB Operating instructions GB
Note: We recommend that you not return the filtered water directly into the pond, but
rather that you introduce the cleaned water indirectly, e.g. via a small watercourse.
This additionally enriches the water with oxygen.
2. Cover the tubing with soil if the tubes are not UV resistant.
Mounting on the cleaning discharge
You will require tube pieces and elbows for the water discharge ( Biotec 18 : DN 50, Biotec
36 : DN 70). Insure that the drain tube is UV resistant if you lay the tubing in the open.
1. Put the tube pieces together and lay the tubing from the water discharge to the
pond on a slight incline (at least 1%).
2. Cover the tubing with soil if the tubes are not UV resistant.
Insert substrate tubes
1. Open the filter cover and swing the sieve insert up.
2. Remove the partition between filter and substrate chamber, in order to more eas-
ily insert the substrate tubes.
3. Remove the protective packaging of the four substrate tubes and insert these in
the guide in the substrate chamber.
4. Re-insert the partition and swing down the sieve insert.
5. Close the lid of the filter.
Now your Biotec filter is ready for operation.
8. Commissioning
– You must read and follow the safety instructions (chap. 4) before the installation!
– The filter system is a biologic system and requires a few weeks until full biologic
effectivity when newly installed.
Correct water jet adjustment
The strength of the water jet depends on the pump capacity; it can be controlled with
the regulator on the water distributor.
1. Turn the pump on.
2. Open the lid of the filter.
3. Adjust the water jet for the filter operation in such a manner that the water jet
occurs in the first third of the sieve. In this manner an optimal turbulence and
distribution of the water is achieved above the sieve surface.
4. Close the lid of the filter.
9. Cleaning/Maintenance
– Follow the safety instructions (chap. 4).
– Clean the filter system only as needed.
– Clean the filter system immediately if the red “Maintenance” LED of the display is
blinking.
Maintenance indicator
If the red “Maintenance” indicator LED is blinking, this can have two causes:
– The “Screenex” has become blocked with debris. Water is no longer running into
the filter; rather it is flowing sideways via the sieve.
Remedy Clean sieve.
– Filter pads are dirty. The water can no longer flow through the dirty filter pads fast
enough. Thereby the water level in the filter container increases.
Remedy Clean filter pads.
