Wet Installation
Using Concrete Filling
1. The supporting construction opening must be prepared in a way depicted in the “Opening preparation” section
(as per Fig. 1 – Fig. 2). Opening surfaces must be even and cleaned. The exible wall opening must be reinforced
as per the standards for plasterboard walls. The opening dimensions are driven by the nominal dimensions of the
damper with added clearance. The opening will be made with dimensions W
1
and H
1
( Fig. 4 ).
2. Insert the closed damper into the middle of the opening so that the damper blade is in the wall. Use the bendable
hanger to secure the damper against the wall by using a suitable screw (3; recommended screw diameter 5,5;
e.g. DIN7981).
For damper widths greater than 600 mm, it is recommended to use a duct support inside the damper during
installation to avoid any damage to the damper housing from the weight of the lling.
3. Fill in the area between the wall and the damper with gypsum plaster, or mortar or concrete lling (2), while
paying attention to prevent the fouling of the damper’s functional parts, which could limit its correct functionality.
The best way is to cover the functional parts during installation. To prevent seepage of the lling material, the use
of boards is recommended.
First let the plaster, mortar or concrete lling harden and then perform the next steps.
4. After the lling hardens, remove the duct support from inside of the damper.
5. If needed, uncover and clean the damper after installation.
6. Check the damper’s functionality.
