Maintenance and cleaning
Waste water outlet
The waste water outlet allows the drainage of polluted water into drains or a flower bed after you have
cleaned the filter sponges.
Cleaning the filter sponges
Over the time, contaminants accumulate inside the filter sponges, and their cleaning effective-
ness will be reduced. Therefore they should be cleaned on a regular bas, even weekly if ne-
cessary.
At any case, they should be cleaned when muddy or even dirty water flows out of the filter and
back into the pond. (The indicator lamp on the cleaning handle turns red.)
To clean the filter sponges proceed as follows:
1. Turn the function switch clockwise to the “cleaning” function until you hear a click.
2. Rotate the cleaning handle several times. Thus the filter sponges are pressed and
cleaned mechanically. Rotate clockwise and counter-clockwise to achieve a better result.
3. You will recognize clean filters when re-flowing water through the transparent hose of the
cleaning port is clean. Now put the function switch again to “filtration.”
4. The filter is now ready for use; check the water inlet to the pond.
Replacement of the filter sponges
If the flow is too low and it cannot be improved by the “cleaning” function, the sponges have to
be washed or replaced.
Please do not use chemical cleaning agents, for not to kill the microorganisms of the filter
sponges!
Proceed as follows:
1. Unplug the power cord.
2. Turn off the pump and make sure that it cannot be reconnected unintentionally. Remove
all nuts and hoses.
3. Remove the safety lock, then open the filter.
4. Lift the filter head with the filter sponges assembly. Place it upside down on a clean sur-
face. The filter sponges are on top.
5. Remove the filter sponges, wash or replace them.
6. Remove the filter sponges and wash them in clean water. Wring them out well afterwards.
The sponges may also be cleaned with pond water.
7. Clean the container, seals and o-rings with a garden hose.
8. Replace the filter sponges back to the previous position.
9. Place the o-ring 3 onto the upper edge of the container (in order to easy fit, you should
make it wet; see below picture of the o-ring 3 position).
10. The safety lock has to be in the right position. Close the clamp.
11. Again connect the filter to all hoses.
12. The filter is ready to operate again.
Caution:
There is a precisely fitting connection between container and lid.
