Inlet connection
We advise the use of a soft connection for the inlet to reduce
the noise and the vibrations of the fan.
To connect the fan inlet to a hose, proceed as follows:
Fig. 4.6
• Loosen the bolts of the inlet grid (A).
• Remove the inlet grid.
• Install the connection flange (B) with the bolts of the inlet
grid.
• Tighten the bolts.
• Attach the soft connection to the connection flange.
• Tighten the hose clamp (C).
• Attach the soft connection to the hose.
• Tighten the hose clamp (D).
Outlet connection
ATTENTION!
In case the fan is not placed directly next to the
filter system, make sure the extraction duct is
sufficiently supported.
We advise the use of a soft connection for the outlet to reduce
the noise and the vibrations of the fan and to avoid damage to
the duct.
To connect the fan outlet to a duct, proceed as follows:
Fig. 4.6
• Attach the soft connection to the outlet of the fan.
• Tighten the hose clamp (E).
• Attach the soft connection to the duct.
• Tighten the hose clamp (F).

Outlet connection
ATTENTION!
In case the fan is not placed directly next to the
filter system, make sure the extraction duct is
sufficiently supported.
We advise the use of a soft connection for the outlet to reduce
the noise and the vibrations of the fan and to avoid damage to
the duct. In addition, we advise the use of a (square to round)
outlet transition.
To connect the fan outlet to a duct, proceed as follows:
Fig. 4.7
• Loosen the bolts of the outlet grid (A).
• Remove the grid.
• Attach the outlet transition to the outlet of the fan with the
bolts of the grid (D).
• Tighten the bolts.
• Attach the soft connection to the outlet transition.
• Tighten the hose clamp (E).
• Attach the soft connection to the duct.
• Tighten the hose clamp (F).
