Installation of the silencer
If the silencer is shorter than the wall thick-
ness, use the location brackets supplied with
the silencer to secure it in the wall.
It is possible to use two of the holes and
screws, which are used to secure the fan.
If the silencer is longer than the wall, unscrew
the retaining screws at the end of the silencer.
Lift off the end plate.
Cut the outer and inner pipe so the length fits
the wall thickness. Trim off excess mineral
wool insulation and mount the inlet plate.
Continue the installation as described below.
