4.6.4 Installation of secondary silencer
Secondary silencers are supplied separately and must
be mounted directly on the VAV terminal unit at the
installation location. Suspend sound attenuator sepa-
rately.
Secondary silencer TX
To optimise acoustics and flow, the TX sound attenuator
has an empty chamber. When mounting, observe the
arrangement of the empty chamber depending on the
installation location of the sound attenuator (in front of
or behind the terminal unit in air direction).
