The pump DC Runner 1.1 is operated by an electronic safety transformer at AC 110 – 240 V / 50 – 60 Hz and
24 V DC output. Power consumption of the pump is max. 7 watts, protection rating is IP X8. To open the pump,
remove retaining plate and release the pump lock (Fig. 2, No. 9) by turning it. The pump must be mounted
with the suction side upwards (see Fig. 1), otherwise the pump may stop.

3. Theory
Protein skimming is a method of physical water treatment. It uses a phenomenon known from our daily
experience: the adhesion of surface active substances to air water layers. If we add a drop of oil to a water
surface, a thin film is produced with a thickness of only one molecule. Surface active compounds like proteins
behave in the same way. The skimmer EVO 500 uses its air bubbles to create a large water surface for the waste
