Aqua Medic EVO 1001 Manual De Instrucciones página 9

Set-up:
Assemble the necessary parts of the skimmer (see Fig. 1). Now, it can be attached to the aquarium. Look for a
protected place within easy reach - at the side or the back. The venturi pump is connected with the pressure
fitting (Fig. 1, No. 10). The length of the flexible hose should be as short as possible. A fixing of the pump
at the glass pane is not necessary. The pump must be placed directly below the surface because the air intake
will decrease and the water flow will increase if it is mounted deeper. This would lead to humid foam and fine
air bubbles.
An 8-mm air tube is connected to the air injector (Fig. 2, No. 10) and fixed above the water level so the pump
can draw in air. Use the full length of the air hose which is attached to the sound absorber (Fig. 1, No. 13). This
will be connected to the holding plate and fixed at the outside above the water level. Now, the skimmer can be
aligned with the aquarium. The two spacer bolts at the bottom of the skimmer are adjusted in such a way that
the skimmer is hanging safely on the aquarium. It is advantageous if the skimmer is not 100% upright but
leaning slightly (2°) to the aquarium (Fig. 4). The skimmer is not only hanging more safely then but also back-
flow of water from the outflow box over the aquarium frame is prevented. Both spacer bolts at the bottom are
supplied with silicone suckers for increased safety. The skimmer is now ready for use and can be started.

Set-up beside or inside the filter tank (Fig. 5):
The EVO 1001 can also be installed in the cabinet filter. It can be placed either in or outside the filter tank.
The set-up outside the aquarium (at the side) is done as described above. It is attached to the edge of the filter
tank. If the filter tank is not high enough, the skimmer is placed beside the tank. If the water level in the filter
tank is very low or there is a shortage of space in the tank, the outflow elbow fitting (Fig. 1, No. 8) may be
connected to the outlet and then water will be directed to the water surface in the tank. This avoids splashing
and reduces noises. The venturi pump is fixed inside the filter tank in such a way that it will not run dry and the
length of the pressure tube shall be kept as short as possible. The pump should be placed close to the water
surface. To prevent the pump running dry, we recommend to use an automatic level controller (e. g. Refill
System, aquaniveau or Niveaumat) to ensure replacement of evaporated water and to keep the water level in
the filter constant.
5. Starting/Performance
The system can be started when the skimmer is correctly installed. After switching on the pump, air is
automatically drawn into the skimmer. To minimize the noise level, connect the air inlet tube with the blue
connecting piece of the silencer supplied. Fix the silencer with the holding device on the aquarium or the filter
system.
The needle wheel breaks the air into small bubbles. This method eliminates the greater proportion of noise.
After the initial start, it might take a few days until the foam production is ideal. This is due to a reaction between
the surface of acrylic glass and aquarium water. Equilibrium of electrical charges takes place. The quantity of
liquid and organic substances is dependent on the pollution of the aquarium.
