In order to ensure the fire resistance of the fire separation element, it is mandatory to keep the embedding envelope
boundary: the damper isolation partition rotation axis must be within the wall envelope.
The embedded fire damper must be coaxially connected to the ventilation duct. Protect the fire damper casing from
damage, and specifically from straining the casing during the installation process. The fire damper cannot bear the
load of the ventilation duct or the ventilation system in which it is installed. Drilling the damper enclosure or driving
screws, bolts or other elements that pierce through the casing to the inside of the damper is prohibited. Once
connected to the ventilation ducts, re-verify the fire damper performance.
During the installation of the mcr FID S/... p/... fire damper mind specifically that the thermal trigger (a fusible element)
must not be damaged or exposed to high temperature (from fire, and welding/soldering equipment), which might
trigger it (it is a single use element and not subject to warranty replacement). Do not expose the intumescent gaskets
installed in the fire damper casing to high temperature. Swollen gaskets make it impossible to close the damper. With
the installation finished, carefully clean the fire damper and make sure that there is no debris which could influence
proper performance of the device.
CAUTION
It is crucial to keep the device embedding envelope so that the trigger control gear is outside of
the wall envelope and easily accessible.
