Filling

Important: Before and during the filling, the horizontal position of the filter must be checked.
The lengthwise embedding of the filter is with smooth sand with a grain size of 8/16 accord-
ing to DIN 4226 – 1 with a width of approximately 30 cm Each layer is to be of no more than
30 cm and must be tamped down lightly with a compacting machine or hand held tamper.
Care must be taken during the embedding to ensure the filter is not damaged. To ensure that
no forces are applied to the filter housing, the telescope must be well embedded and com-
pacted. (For areas traversed by light traffic see section 5.3.2) Finally, the cover is set in place
and secured so that it is child proof (Section 1.1 must be followed). The
screws holding down the cover are to be made so tight that they can
not be removed and the cover opened by a child!
5.5 Installation and removal (lift out mechanism)
To facilitate removal of the filter unit in cases of a deeper installation, the
removal – lift out mechanism that is included in the delivery pack should
also be assembled. The screws of the upper connecting rod should be em-
ployed for the assembly.
