Please refer to the attached manual.
3.4. Maintenance / Cleaning the pump
Depending on contamination, the pump and Power Wheel have to be cleaned occasionally, at least in two-months
intervals, if necessary more frequently.
First of all, remove the retaining plate. Then, take off the pump lock. Now, the complete impeller can be taken
out.
4. 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 (Fig. 1, No. 5). The silencer has to be
put into a borehole of the foam cup's lid. 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.
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 (Fig. 1, No. 6) 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.
Fig. 3: There is a height-adjustable overflow pipe in the foam cup. From there, the water can be led from the
foam cup into a container standing next to the skimmer. Make sure that the external container does not overflow.
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.
5. 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.
