TECHNICALLY REQUIRED MINIMUM DISTANCES
To allow regular and extraordinary maintenance work on the unit, minimum distances
of
1 m
from walls, railings, other appliances or similar obstacles must be provided on
all sides of the unit.
If the unit is inadequately fixed, it may come loose and start moving. There is a danger of per-
sonal injury or damage to property.
Secure the device properly and in accordance with the requirements of the installation site. The fasteners
must be distributed evenly across all system feet. Both through holes in the feet must be used for screw
connections. The type of fastener must be determined independently by the installer. Check whether drilling
into the ceiling is permitted.
The fastening is planned and completed on site. In particular, when selecting the fasteners and weights for
any loading, the expected weather conditions and other project-specific influencing factors must be taken
into account. The dimensioning of the fastening must be carried out in accordance with DIN EN 1991-1-4.

continuous operation. A corresponding release line is therefore not provided for the ventilation components.
