Fig. 4: Turboflotor Multi SL, hang on, tilted at 2%
Set up beside or inside the filter tank of a sump or under tank filter system (Fig. 4)
The Turboflotor Multi SL can also be used in a sump or under tank filter system. It can be placed
either in- or outside the filter.
See the above hang-on procedures for installing the skimmer on the outside of the filter tank. It is
attached to the frame of the filter tank. If the filter tank is not high enough, the skimmer is placed
beside the tank. For the return flow, outflow boxes (9) may be used. If the water level in the filter
tank is very low or there is a shortage of space in the tank, two 90°-elbow fittings may be
connected to the outlets (7) and the water will then directed down to the water surface in the tank.
This avoids splashing and reduces noise. 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 is kept as short as possible (Fig. 4).
The pump should be placed close to the water surface. To prevent the pump from running dry, we
recommend to use an automatic level controller (e. g. aquaniveau single) to ensure replacement of
evaporated water and to keep the water level in the filter constant.
