Inserting the filter

The stainless steel cross bar supplied
/ max. 690 mm) and then attached to the shaft's collar. The prepared filter
tank dome from above, slid onto the supply pipe, which is protruding at least 100 mm, and fitted in the
cross bar using the previously adjusted chain suspension
Please note, that the filter basket has to be installed above the maximum water level. This prevents
that pollution in the filter decomposes and thus the water gets contaminated.
The strainer insert is removed for cleaning. During this process the strainer is rinsed thoroughly with water
until all pores are open. We would recommend cleaning every 4 - 5 weeks depending on dirt levels (more
frequently in autumn when the number of leaves present increases greatly).
After cleaning the filter strainer must always be refitted correctly or installed and fixed correctly using
the chain suspension. The overflow siphon should also be checked during maintenance and rinsed if
necessary.
