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 with union nut
(13). Please make sure that the O-rings (14) are placed into the groove.
If possible, mount the pump horizontally for best air power and quiet operation.

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.
3.3. DC Runner Controller 1.1
The included DC Runner Controller is switched between power supply and pump to adjust the output. The
power can be adjusted by pressing the +/- buttons, the level is displayed by LED. If you press the button
„FEED", the output will stop for 10 minutes.
There is an automatic shut off if there is no water for 2 minutes. Pull the plug and then re-insert it to take
the controller back into operation. Controller, plugs and sockets have to be kept dry.
0 - 10 V: The pumps must be operated with at least 60% power, otherwise damage will occur. When
inserting the plug into the 0 - 10 V socket (Fig. 3, No. 4) it will be switched to 0 – 10 V automatically, this
will be indicated by two lit LEDs.
