ATTENTION
Smoke exhaust roof fans F400/F600 – B VD
can be screwed in on all four sides of the housing in the thread of the mounting screws of the discharge-side protection
guard.
These eyebolts must not be used as anchor points to lit the fan in any case . The anchor points are identified
separately with a label sticker, see shipping section .
The roof fan attenuator B HSDV has four mounted eyebolts for all sizes as standard.
If necessary, these eyebolts on the fan and roof fan attenuator can be used for on-site anchoring under high wind
loads. The need for on-site anchoring must be checked in individual cases depending on the local wind influences.
The installer must anchor the fan at the provided anchor points if such environmental influences are expected. The wind
load should be calculated according to DIN EN 1991-1-4.
