INSTALLATION INFORMATION
The multi-leaf dampers must not be tilted during installation.
Otherwise, this may result in problems with the adjustment
mechanism or in leaks.
The multi-leaf dampers are delivered in open position (cur-
rentless OPEN) and must be mounted as such.
NRWGs must be installed such that external forces do not
impair their permanent functioning.
They must be fastened by means of suitable mounting mate-
rials approved by the building supervisory authorities (see
Accessories) in accordance with the mounting instructions.
Protection from weather conditions must be guaranteed on
site!
