There may be some scratches on the inner wall surface of the duct. This happens in the factory in the testing and balancing process.
The scratches have no affect on performance.

We will not accept units back because of this scratching


Do not touch the centre fan mounting screw unless you have to replace the fan blades as this will destroy the dynamic balancing
