4.1. 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.
4.2. DC Runner Controller
Please refer to the attached manual.
4.3. Maintenance / Cleaning the pump
Depending on contamination, the pump and needle wheel have to be cleaned occasionally, at least in two-
months intervals, if necessary more frequently. First of all, the pump is dismantled in reverse order according
to the installation instructions. Then, take off the pump lock. Now, the complete impeller can be taken out.
5. Starting the skimmer
 The air tube has always to be installed upward over the water level in the skimmer. This air tube must not
hang down. Therefore, it should always be connected to the silencer. Connect the bottom end of the tube
to the air intake of the pump. The foam cup is simply inserted into the skimmer's housing from the top.
 The ideal water level for each skimmer is listed in the table. With higher or lower water levels, airflow rate
and skimming power will decrease. The filter sump should either contain an overflow edge that keeps the
water level in the ideal range or it should be equipped with an automatic refill unit, such as Aqua Medic Refill
System easy.
 The skimmer will be filled by starting the venturi pump on a low level. A very quick water flow leads to very
fast overflowing of the foam cup. Here, special caution is required, if one connects the outflow nozzle of the
foam cup via a hose with a container standing beside the filter sump. There is the danger that the container
overflows if the skimmer cooks over. Thus, this would also lead to strong loss of water in the filter sump
whereby other devices could run dry and therefore, could be damaged. The flow should be adjusted by using
the adjusting screw and/or the pump controller so that a nearly dry foam will be produced. There is an arrow
on the adjusting screw. If it points to the skimmer, the outlet is set to the lowest level.
 Ensure, when filling the skimmer that the water level of the aquarium resp. filter sump is not lowered too
much. Possibly, keep freshly prepared saltwater ready for refilling.
 After first use or after cleaning the skimmer, it takes some time for the initial foam to build up in the reaction
pipe of the collection cup. This is because the cleaned acrylic initially reacts with the water until a build up of
fatty acids naturally takes place.
 After approx. 24 hours, the foam should be pushed slowly and evenly into the collection cup. The quantity of
liquid and organic substances depends on the pollution of the aquarium.
6. Maintenance
 Foam cup: Depending on the organic load, the cup should be cleaned daily to weekly.
 Skimmer pipe: This only needs occasional cleaning. We recommend intervals from 6 to 12 months.
 Reaction pipe: For a complete cleaning, the base can be unscrewed.
 Venturi pump: The maintenance of the pump should be done at least every two months, if necessary, even
more often:
- Drain the water out and dismantle the pump. Flush the pump housing and needle wheel with clean water
and, if necessary, use a brush. The same should be done with the air injection nozzle.
7. Failures
Problem: The pump or the skimmer do not run properly or not at all.
Cause: Check that the ceramic axle of the needle wheel rotates freely in the ceramic bushing of the
pump bearing.
Action: Clean the pump more often. Try to turn the ceramic axle carefully in the bushing.
