Notes
● The fan is designed for installation on a roof directly
above a ventilation shaft or ventilation pipe.
● Observe the permissible roof load.
● Install ventilation ducts properly.
● Lay the mains cable firmly to the installation site.
● It is essential to observe the relevant regulations for
electrical installation and device mounting, in Germany
in particular DIN VDE 0100 with the corresponding parts.
● To avoid vibration transmission to the pipe system, use
elastic fastening collars (type ELR).
● To avoid leakage, only screw the roof base onto a
suitable, level substructure. For direct mounting of the
RADONTEC ALPHAEX on the ventilation duct, dismantle
the roof base (3 self-tapping screws).
● Use suitable insulation, soundproofing and in
stallation
material between the unit and the roof base.
● The fan can be mounted on a roof box to prevent snow
and water from entering a ventilation pipe.
