The fan is designed for mounting on a roof directly above a ventilation shaft or an air duct.
Installation procedure and mounting sequence are shown on pages 15-18.
To prevent water and snow ingress inside a ventilation shaft, the fan can be mounted on
a roof curb.
A roof fan can be connected to a ventilation shaft with an intake flange that is fixed directly
to the fan base.
The fan base has holes for fastening bolts for connection of the fan to the level surface or
to the roof curb.
The roof curb, intake flange and fastening bolts are not included in the delivery set and can
be ordered separately.
Power is supplied via a remote terminal box or a terminal box built into the motor casing.
The unit is rated as a Class I electrical appliance and must be grounded.
The terminal must be connected to the ground loop.
The fan design is constantly being improved, thus some models may be slightly different from
those described in this manual.
