USE OF FIRE DAMPER
To activate the damper rotate the control lever counter-clockwise.
To release the damper press the button highlighted in the figure.
IMPORTANT: Pay attention to the direction of rotation of the
lever: in case of vigorous rotation in the wrong direction the
closing device may break.
IMPORTANT: After installation, check that there are no
obstacles for the correct blade rotation.
IMPORTANT: When the AHU is disconnected from
the structure, close or protect ductworks to prevent
atmospheric elements from entering.
INSTALLATION OF FIRE DAMPER ON RIGID WALL
1
Prepare in the wall an opening with both base and height
increased by 85 mm with respect to the nominal dimensions
of the damper; for walls made of concrete blocks or bricks it
is recommended to provide a strengthening beam above the
opening;
2
Insert the damper in the opening so that the fixing flange
rests on the wall surface;
3
Fasten the damper to the wall through the holes present
in the fixing flange using self-tapping screws or screw anchors
with 6 mm diameter.
For further information, refer to the manual supplied with
the dampers.
