4. Dimensions and connection measures
There are 3 marked areas for attaching the inlets in DN110 and DN160 as well as 2 outlet
nozzles (1 x DN 110 or 1 x DN 160) to choose from. The suitable seal (DN110 or DN160) is
included of the respective filter
5. Extension
Using the extension RWZR2153 the filter can be adapted to the
ground level and the position of the tube route.
A needs-based
height adjustment is made by sawing off.
A larger difference is
realizable by using 2 extensions.
The extension tube may have to be ordered separately
6. Installation
Avoid damaging buildings, pipelines and vegetation. Underneath the filter there has to be a well
compacted water-permeable stable layer of filling material of at least 100mm thickness. It must
be able to take weight, compactable and must be frost-proof. Suggested is gravel 0/32. Do not
use
cohesive soils.
The further filling has to be arranged by layers of 100mm each. For the last
100mm under the ground surface any material is usable. The outflow tubes must have at least
the diameter of the inflows,
as well as have the same or greater gradient than the inlet pipes
