Installation
General points
∎
The installation must comply with the installation manual delivered with the product and the classification report.
∎
Axis orientation: see the declaration of performance.
∎
Avoid obstruction of adjoining ducts.
∎
Product installation: always with closed damper blade.
∎
Verify if the blade can move freely.
∎
Please observe safety distances with respect to other construction elements. The operating mechanism must also remain
accessible: allow for a clearance of 200 mm around the housing.
∎
The air tightness class will be maintained if the damper is installed according to the installation manual.
∎
Rf-t fire dampers are always tested in standardised constructions according to EN 1366-2. The achieved results are valid for similar
supporting constructions with a fire resistance, thickness and density equal or superior to the supporting construction used
during the test.
∎
The damper must remain accessible for inspection and maintenance.
∎
Schedule at least two running visual checks each year.
