(as per
Fig. 1 and Fig. 2). Opening surfaces must be even and cleaned off. The exible wall opening must be
reinforced as per the standards for plasterboard walls. Insert the open damper into the middle of the opening so that
the damper blade is in the wall.
2. For installation purposes, make a round opening with a diameter of DN + 60 mm into the wall.
3. Insert the duct inside the middle of the opening.
Applies only for Installation with Continuous Duct:
With one end of the duct not further than 500 mm as the damper must remain accessible for installation
and inspection. Additional label provided in the packaging must be applied on the duct on the inspection side.
Applies only for Installation into the End of a Duct Fitted with Valve:
End of the duct must be aligned with the wall/ceiling surface on the side of future valve placement.
Additional label provided in the packaging must be applied in to the duct on the valve side.
4. Fill in the area between the wall and the damper with mineral wool (3) thoroughly but in such a way that will not
deform the duct.
5. Check the damper’s functionality
6. Insert the open re damper into the duct with the distance of 45 ± 10 mm from one wall edge to the damper body
(side with external gasket).
7. Close the gap between the damper and the mounting opening, use PRC coverplates (5) with screws (6)
through pre-drilled holes.
8. All the gaps between the coverplates, between coverplates and the wall and between coverplates and the duct
need to be lled with re resistive coating (7).
