Rigid floor/ceiling installation (mortar sealing)

The floor/ceiling is composed of concrete blocks
(minimum density of 550 kg/m³) or reinforced
concrete (minimum density of 2200 kg/m³) and

with a minimum thickness of 100 mm. Installation
material is gypsum plaster or mortar.

INSTALLATION

1. Create an opening in the floor/ceiling (minimal

dimensions on page 13) and bend the fixing
bracket

(1)

90°. Place the damper in the opening

up to the wall limit mark

(7)

on the damper.

Damper blade must be closed during installation!

2. Fix the damper to the slab using screws (bracket

screw hole is 6 mm in diameter).

3. /3*. Fill the space between the damper and the

slab with mortar

(2)

or gypsum plaster.

Test the operation of the damper blade!
