Principle of operation
The skimmer with venturi pump has to be placed in a separate filter tank. The water is pumped to the skimmer
by the venturi pump. The pump draws water from the filter tank and mixes it with air. Within the pump housing,
the bubbles are cut into very fine pieces by the Aqua Medic Power Wheel. The air/water mixture is pumped back
into the skimmer. The treated water flows through the outlet out of the skimmer back into the filter tank.

Venturi pump
The
DC Runner
series of magnetically coupled centrifugal pumps are very quiet in operation. They have fully
encapsulated synchronous motors. All materials are saltwater resistant.
The polished ceramic shaft and bearing is practically wear-resistant, ensuring a long operating life. The pumps
can easily be taken apart for cleaning. The direction of the rotation is controlled electronically. This enables a
very efficient operation.
3.1. Connections
Suction side:
The included air injection nozzle is placed at the pump’s suction side.
Pressure side:
The pressure side is connected to the skimmer by the existing connection by a piece of hose.
Please make sure that the O-ring (Fig. 1, No. 18) is placed into the groove.
If possible, mount the pump horizontally for best air power and quiet operation.
Fig. 2: Depending on the available space, the pump can be mounted in different positions.
3.2. Setup of the pump
The pump DC Runner is operated by an electronic safety transformer at AC 110 – 240 V / 50 – 60 Hz and 24 V
DC output. To open the pump, remove retaining plate and release the pump lock by turning it. After setting the
pump up, please ensure you can always reach the power plug easily.
Safety advices
The pump is constructed for indoor use only. Before working on the aquarium or pump, the power
plug has to be disconnected from the mains. The connection cable and the power plug must not be
changed. If the power cable is damaged, the pump must be scrapped.
