SPECIFICATIONS/GENERAL INFORMATION

Fire damper suitable for installation on a wall, light wall and ceiling made from duct and galvanized steel components

, calcium silicate blade mono slab sp. 25 mm with perimeter seals to ensure sealing requirements to cold and hot

smoke. The control device ( manual with electromagnetic release or motorized ) consists of a plate removable and

replaceable even after installation, on which they are installed all the elements necessary for the proper operation and

functioning of the ﬁre damper; the particular geometry of the control mechanism, prevents that the pressure present

in the duct (up to 500 Pa) opening the blade if not acting directly from the reset lever. When installation is completed,

the command will be out of the masonry simplify any post-installation actions. The dampers, installed according to

the instructions in this manual , are used in HVAC systems by restoring the partitioning between two rooms, ensuring

perfect insulation from heat and smoke seal.

The installer has the obligation to follow the installation procedures and use of the equipment described in this

manual, in order to comply with the same conditions as the samples to be tested. Any deviation from the instruc-

tions, affect the validity of the certiﬁcation of the product and the declaration of correct installation

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

(Fig.3A).

CEILING 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 floor (fig.1A) having larger dimensions than the nominal size of the damper (see

table 1 according to the type of installation).

3 Place the center of the opening the damper, taking care that the plane containing the blade in the closed

position is parallel to the slab, and comply with the protrusions shown in fig.2 Table 1

4 Fix the damper to the floor with the brackets, then fill with cement mortar class M10

PRECAUTIONS FOR HANDLING AND INSTALLATION

CAUTION!

• All operations of handling and installation shall be made with the blade of the ﬁre damper in the closed position

(our standard delivery).

• All operations of connection power line must be performed by qualiﬁed service personnel.

• Keep clean the connecting end from residues of cement to securely connect the rest of the duct

• Avoid any deformation of the duct and / or obstacle inside the duct which may prevent the successful rotation of

the blade

• Check that there are no external obstacles (cables, pipes, etc. ..) to prevent the correct operation of the controls

outside of the duct

• Keep the most accessible as possible to the control side in order to ensure the necessary space usage and mainte-

nance of the damper.

MAINTENANCE

Is advisable to periodically run a check the correct operation of the actuating and signal the damper. In particular,

check the correct and complete opening and closing of the blade: for the operation of the controls follow the instruc-

tions listed “CONTROL OPERATION.” Also check that the warning devices at the beginning and ending are in good

condition and working properly.
