english 2c) Use of empty shafts or
unused
chimneys
In a property with an unused
chimney or empty shafts, the
tubes can be vertically routed
from the vacuum sockets to the
vacuum unit inside the chimney
through the floors.
1. Determine the positions of
the vacuum sockets. Ensure
that the vacuum sockets are
not directly opposite each
other but have a height diffe-
rence of at least 17 cm.
2. Then draw a diagram sho-
wing the socket arrangement
with exact distances and
lengths.
3. The tubes can now be as-
sembled without using adhe-
sive.
4. If everything is correct, mark
the tubes as described in
3.1.1 “General rules”.
5. Glue the tubes to smaller
elements so that they can be
conveniently inserted into the chimney.
6. Now glue the elements to each other, paying attention to the
marks and directions.
7. Secure the tubes and attach the vacuum socket connections to
the tube system.
Tips + Tricks when installing in
existing houses:
• Install suction tube along base of
wall or in a corner.
• Install the suction tube system
behind furniture. You can then
make a vacuum socket break-
through behind the furniture so
that a vacuum socket can be
installed in the adjacent room.
• Please note that floor vacuum
sockets must always be located
near the wall in order to minimise
the risk of tripping.
