4. Placement and Assembly
4.1.
Smoke control dampers single are designed to remove heat and combustion products (e.g. smoke) from single fire
compartment according EN1366-9.
Smoke control dampers single are designed for installation with horizontal or vertical axis of the blades. Backtoback smoke
exhaust duct has to be hung or supported so as all load transfer from the backtoback smoke exhaust duct to the
damper is absolutely excluded. To provide needed access space to the control device, all other objects must
be situated at least 350 mm from the control parts of the damper.
4.2.
During installation the damper blade must be in position CLOSED. The damper body should not be deformed
in the course of installation. Once the damper built in, its blade should not grind on the damper body during opening
or closing.
