Before commissioning and at every inspection, the lifting out mechanism must be positioned at 90° to the
inlet so that no large objects such as leaves and twigs can catch on the handle. The straining filter is
removed for cleaning and the basket must be thoroughly cleaned with water until all the pores are open. It
is advised to clean every 4 to 5 weeks (more often in autumn due to more leaves and twigs) or according
to requirements.
The filter strainer basket must be lightly pressed into place taking care that the seal sits precisely after
every cleaning.
At the occasion of each inspection, the overflow siphon must be checked and flushed in necessary.
