Assembly: Ald-S - Lunos ALD Einbauanleitung

Assembly: ALD-S

Prepare the wall opening for the wall-tube
(e.g. via core drilling, core bit Ø162 mm).
If necessary, shorten the wall-tube to the
installation length required. In doing so, en-
sure the necessary excess length of the tube
on both sides to bridge the plaster thickness.
If necessary, reduce the sound-absorber in
such a way that the outlined distances to the
pipe edge remain the same.
If necessary, shorten the outer star-shaped
sound-absorber e.g. using a cutter knife.
Insert the wall-tube and seal it all around
(assembly adhesive Order No. 038 733).
Apply the internal and external plaster.
In the case of an external closure to be plas-
tered, first replace the plaster protection cap
outside with the external closure.
Arrange the sound-absorber twistedly towards
one another, as pictured.
