The dampers must be suspended using threaded rods and
mounting profiles. Their dimensioning depend on the
weight of the damper.
■
The dampers and the duct must be suspended separately.
■
Following air-conditioning duct must be suspended or
supported so that all load transfer from the following duct
to the damper flanges is absolutely excluded. Adjacent
duct must be suspended or supported, as required by the
duct suppliers.

Threaded rods longer than 1,5 m must be protected by
fire insulation.
