7. LIGHT WALL INSTALLATION
1 Before proceeding with the installation, verify the integrity of the damper, the correct positioning of the blade in the
closed position and operation of the command.
2 Provide an opening in the wall (fig.1A) having larger dimensions than the nominal size of the damper (see table 1
according to the type of installation).
3 Apply band expanding around the entire perimeter of the damper. Place the center of the opening the damper and
making sure that the blade in the closed position is parallel to the wall. Maintain the axis of rotation of the blade
horizontal as from tests carried out. Observe the projections indicated in fig.2A Table 1.
4 Fix the damper to the wall using the brackets, then fill with cement mortar class M10 and dab from both of the sides
of the wall with the plasterboard thickness 12.5mm.

8. SUGGESTIONS
After installation it is recommended to perform a function test by checking the correct rotation of the blade and the
efficiency of the command (manual or motorized). It can be done in manual version rearming, with the lever, the
damper and pressing the test button simulating so the operation. In the motorized version act on the lever of the
thermoelectric fuse.
