Launching, Usage And Adjustment Of The Filter; Flooding Of The Filter With Water And Other Preparations - Aquael Unimax Professional FZKN 500 Manual Del Usuario

Elastic conduits (18) need not be fastened yet, this will be done later – see description at figures 16÷17.
Fig. 14. The figure – looking from the inside of the aquarium – shows an example of inlet element layout. The manner of
placement of the inlet elements may be adapted to the shape of the specific aquarium. We may only point out that later,
during automatic flooding of the filter with water drawn in form the aquarium, the water level in the aquarium will sig-
nificantly drop. During this operation, water from the aquarium will flow to the filter in the quantity of ca. 13-14 liters (the
case of FZKN 500) or ca. 18-19 l (the case of FZKN 700), and the drawing elements, that is the drawing pipe (2) and/or the
drawing basket (19) even at the end of this process should be in total submersion. Therefore, using appropriate quantity
of connecting pipes (35), the parts (2) and (19) should be submerged as deep as possible.
Fig. 15. The figure – also from the inside – shows the temporary layout of outlet elements. Why „temporary"? An explana-
tion is due here:
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 through
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 (2) (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 aquar-
ium, 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 inscription
„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 inscription
„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, ac-
cording to arrow 'I' . In this position all inlets and outlets of the filter are closed.
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 pro-
cess 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.
