6. Scope of delivery
Upon receipt of the shipment check the packing lists to make sure the shipment is
complete. If you are missing parts please report in writing to the shipping

If the fan is not installed immediately after shipment, it has to be properly stored at
a protected location. The fan has to be properly covered to make sure no dust or
moisture can enter the fan.
Turn the impeller by hand several rotations once a month.

9. Technical information
Air inlet and outlet
The characteristic curves imply a uniform irrotational speed distribution in the fan
inlet. This means for instance that an inlet nozzle has to be mounted in an open
inlet.
If mounted in channels or pipelines an inlet or discharge area of 1.5 times the
diameter of the fan has to be provided.
If the design does not allow that, baffle plates have to be mounted to optimize the
air flow, so that the air speed is as equal as possible when entering the fan.
For an open outlet of the fan the shock loss in relation to the discharge speed (ring
surface) has to be observed.
