5. Use a measuring tape to meas-
ure 42 cm (for ∅ 65 - 75 mm)
or 43 cm (for ∅ 76 - 95 mm)
downwards from the top and
mark this position (fig. D).
6. Slide the installation aid down
to this marked position and
mark the lower edge for instal-
lation, again, if possible over
the entire diameter, of the
downpipe (fig. D).
7. Use a suitable saw to cut out
the marked section from the
downpipe. Ensure that the cut
is clean and straight (fig. E).
Use a file to deburr the cut
edges.
3. Cleaning the filter
The condition of the fine mesh
8
filter
can be determined by
looking through the transparent
4
filter hood
. The fine mesh filter
is practically a self cleaning filter,
larger items such as leaves are
held back from the flow by the
coarse filter at the filter inlet and
pass down the downpipe.
Cleaning the coarse filter
To clean the coarse filter (block-
age by larger items e.g. leaves)
remove the Rain Water Collection
Filter reversing the installation
4. Shutting off the collection of water
Before the frost period begins
or if the Rain Water Tank is full,
the collection of water can be
shut off as follows:
1. Open the filter hood
shown in fig. H.
5. Integrated overflow
If the outlet of the Rain Water
Collection Filter is installed at the
same height as the Rain Water

between both ends of the
downpipe (e).
5. Connect the Rain Water
Collection Filter and the
(fig. H / I)
procedure. Then remove all block-
ing items and reinstall the Rain
Water Collection Filter.
Tip : If your gutter tends to block,
we recommend the installation of
a leaf collector box at the upper
entrance to the downpipe.
Cleaning the fine mesh filter
Should however the fine mesh
filter become blocked, it can be
cleaned as follows:
1. Open the Rain Water Collection
Filter by unfolding the filter
hood
2. Turn the outlet bypass
downwards and away from
you (fig. J) and close the filter
hood again.
