Installation of the damper outside the wall is considered a violation of this rule. In case of such an application of
dampers, the section of the ventilation duct present between the damper partition and the fire separation has to be
protected using fire protection panels or layers of mineral wool, as well as a structural reinforcement in accordance
with the Manufacturer's recommendation.
Connecting the embedded damper to the ventilation duct has to be made coaxially. During the damper installation,
the damage to the damper body should be prevented, particularly its strains. The damper may not be a "load bearing
element" of the duct or the ventilation system on which it is installed. Drilling through the damper enclosure, driving
screws, bolts or other elements passing through the enclosure to the inside of the damper is unacceptable. After
connecting the ventilation duct, check the correctness of damper operation again.
During the installation of a mcr FID S/... c/P damper, pay particular attention so that the thermal release (fuse element)
do not get damaged, do not expose it to high temperature (fire, welders, soldering irons) that cause its activation (it
is a single use element and is not subject to warranty replacement). Do not expose swelling gaskets installed in the
damper enclosure to high temperature. Gasket swelling makes it impossible to close the damper. After finishing the
installation, carefully clean the damper and make sure that there is no debris which could influence the correctness
of operation.
NOTE
It is crucial to observe the device embedding border, so that the release and control mechanism is
outside the separation wall and allows easy access.
