Warnings
Some grille parts may have sharp edges – therefore to protect yourself from harm, please use gloves during
installation and manipulation. In order to prevent electric shock, re or any other damage which could result
from incorrect damper usage and operation, it is important to:
1. ensure that installation is performed by a trained person.
2. follow the written and depicted instructions provided within this User Manual closely.
3. perform air transfer grille inspection in accordance with this User Manual.
4. check the damper’s functionality as per the chapter “FGS Functionality Check” on page 17 before you
can install the grille. This procedure prevents the installation of a damper that has been damaged during
transportation or handling.
Do not install non-functioning air transfer grille!
Installation
• The air transfer grille driving mechanism can be placed on either side of the wall, however it needs to be placed so
as to ensure easy access during inspection.
• The distance between the air transfer grilles mounting frames must be at least 200 mm according to EN 1634-1.
• The distance between the wall/ceiling and the air transfer grille mounting frame must be at least 250 mm according
to EN 1634-1.
• The air transfer grille must be installed into a re partition supporting construction in such a way that the blades are
located inside this supporting construction and the frame suspension plane is aligned with its surface.
• The gap in the installation opening between the air transfer grille and the wall/ceiling can be increased by up
to 50% of the gap area, or decreased to the smallest amount possible that still provides sufcient space for the
installation of the seal.
• In case of installation into thicker supporting construction than the provided frame its mesh should be mounted on
the mounting frame thereby nested in the supporting construction.
• Installation into thinner wall is allowed only if the thickness of the wall in circumference 200 mm from the opening
is constructed in the same way and with the same thickness as prescribed in this manual. The resistivity is
decreased to the level of the thinner supporting construction.
• All air transfer grilles can be installed only with the blade axis in a horizontal position.
• The air transfer grille must not bear any part of the supporting construction. This could lead to damage and the
subsequent failure of the Air Transfer Grille.
