The fan should be transported horizon-
tally and may only be lifted by the lower 
casing (for VDA 200 to 560, see pos. 7, for

base (VDA 200 to 560, see pos. 13).

Installation of the VDA roof 
fan

■

 The fan must be installed horizontally 

in order to prevent wind and rain from 
entering;

■

 A weather resistant seal of sufficient 

thickness should be fitted under the fan 
to ensure airtight installation;

■

 Using bolts and rings, ensure that the 

fan is mounted securely so that in the 
event of heavy winds it remains in situ;

■

 When mounting the fan on a silencer 

(type GDH or GDB) or roof mounting 
curb (type DOS), use must be made of 
the mounting bolts and rings supplied 
and fitted;

■

 Install the fan in such a manner that 

there is no risk of any person touch-
ing the side of the fan not fitted with a 
protective grille (see EN 294).
