R.6.2 Dampers
Rubber seals between the damper blades and the frame
are to be checked once a year. These seals are not to be
lubricated or treated in any other way.
Each damper blade is driven by a gear drive of a tempera-
ture-resistant, glass-fibre reinforced PA6 nylon compo-
site. Gear-drive as well as bearings do not require
lubrication
The damper blades are fitted with synthetic bearings requiring no lubrication. Air-tightness of the damper, when the
damper motor is in the closed position, must be visually checked once a year. The damper motor is to be adjusted if the
damper does not close tightly.
