During the automatic flooding of the filter with water drawn in from the aquarium (this operation is described in item
6), similarly as in the case of the inlet system, the ends of the outlet water lines must also be submerged, because during
this operation water may be sucked into the filter not only through the inlet elements according to figure 14, but also thro-
ugh the outlet conduits.
Therefore, in setting up this temporary layout it is important that:
• the ends of the „pipelines" are placed in the water as low as possible,
• the ends of the pipes must closed with mesh – e.g. parts (38) (otherwise small fish may be sucked into the filter).
Fig. 16-17. Considering the location of the filter and placement of the inlet and outlet assemblies on the edge of the
aquarium, from the elastic conduit (18) supplied in one piece you need to cut four sections as appropriate. The hoses may
be of different lengths, depending on the setting of the filter respective of the aquarium.
The bottom ends of the inlet conduits should be pressed until refusal onto the inlet stubs of the filter with the inscrip-
tion „IN", and secured with clamp nuts (17). The top ends of these conduits should in the same way be connected to
external stubs of the inlet system (figure 14.), here the ends of the conduits needs also to be secured with clamp nuts
(figure 13.).
In the same way you should connect the inlet conduits: at the bottom to the outlet stubs of the filter with the inscrip-
tion „OUT", and at the top to the outlet system (figure 15.), not forgetting to secure all ends of the conduits with clamp
nuts (17).
NOTES:
• In order to ensure tightness, the ends of the elastic conduits need to be cut straight and pressed until refusal onto the stubs.
• In order to ensure longevity of the elastic conduits, they should be guided along the shortest route from the filter to the
aquarium, so they do not hang loose or bend or loop (fig. 17).
Possible folds of the elastic conduits may be straightened out in warm water, which will make them soft. Hose ends can
also be softened in warm water, which facilitates making connections.
To carry out the operations described above it is not necessary to take out the control unit (16). However, if – for the purpose
of easier connection of the elastic conduits or out of simple curiosity – we wish to remove it, it is possible. The manner of
removal and replacement of the control unit is described in item 7.1, see figure 21, and in item 7.4, see figures 27-29.

6. LAUNCHING, USAGE AND ADJUSTMENT OF THE FILTER

Following performance of all preparatory operations described in chapter 5, the aquarium should – if it is still empty – be
filled with water, to the possibly highest level.

6.1. Flooding of the filter with water and other preparations

Fig. 18. Turn the control unit (16) in the cover (1) clockwise by 45° until refusal, into the position shown in the figure,
according to arrow 'I' . In this position all inlets and outlets of the filter are closed. [In the course of this action the turn lock
(19) slightly moves out, but this is of no importance at this point.]
Pull up the tip of the auxiliary pump „P", pump it several times (5-10) vigorously according to the arrow II, and finally leave
it in the bottom position. This way some of the air is pumped out of the filter, and there is a partial vacuum inside.
Directly after these pumping motions set the control unit vigorously back into its original position (shown on figure 16.).
Now the negative pressure causes automatic suction of water from the aquarium into the filter. In the first phase this
process may take place slowly, but nevertheless it should lead to automatic filling of the filter with water.
If – for reason of inadequately vigorous pumping movements, or delay in commencement of flooding – automatic flood-
ing of the filter with water does not take place, the operation described above should be repeated, increasing somewhat
the number and vigorousness of movements, and after the pumping the control unit (16) should be replaced promptly,
right away and without delay.
The quantity of water sucked this way is taken from the aquarium, which should be replenished.
NOTE: The auxiliary pump „P" after this operation is in the bottom position, and it should stay this way. However, its
rising (even during operation of the filter) does not cause any interference in the operation of the filter, nevertheless we
recommend not to raise it, because it may then be difficult to press it back into the bottom position.
Fig. 19. Verify the position of the turn lock (19). If it is otherwise, we request to set it in bottom position „19Q". In this
position it prevents making unknowing motions that nay lead to removal of the control unit.
Fig. 20. Remove – and put aside for subsequent launches in the future – the terminal elements of the temporary outlet
system, which was assembled according to figure 15 for the purpose of effecting automatic flooding of the filter with
