PRIOR TO ASSEMBLY AND COMMISSIONING
Each SCHAKO product comes with in-
structions on [Safety / Transport /
Disposal] and [Installation / Commis-
sioning / Maintenance]. For safety
reasons, they must be read and ob-
served. Multi-leaf dampers may not
be lifted at the louvres and not be
used as "ladder".
At the gear wheels and cutting edges, there is a risk of injury.
Mounting to the wall/ceiling must take place without defor-
mation, without tensions, level and without angular errors.
The multi-leaf dampers must be installed in open position.
MARKING
The product is labelled with the marking
shown opposite in accordance with the
Construction Products Regulation

The operating safety of the devices is
only guaranteed when used in accord-
ance with their designated use.
DISPOSAL
After its final decommissioning, the multi-leaf damper must
be properly disposed of by a competent body.

ance with legal regulations (at yearly intervals). Accordingly,
functional checks should also be carried out at regular inter-
vals. Maintenance must always be performed by personnel
trained for this purpose.
Note
Impure and humid air may impair permanent operational
safety. If maintenance agreements are concluded for RWA
systems, the functional checks of the NRWG should be in-
cluded in these maintenance agreements.
VERIFICATION
Visual inspection
Check NRWGs for damage and contamination
Carry out necessary cleaning work
When cleaning, please note that cleaning agents may
damage seals.
Functional check
Check actuator for perfect functioning and condition (ob-
serve manufacturer's operating instructions)
Check actuators and fastening for tight fit
Check entire opening and closing process of the NRWG:
-
Spring return
