The correct wheel-to-inlet clearance is critical to proper fan performance.

Verify the wheel-to-inlet clearance before initial start-up.

Adjust the overlap by loosening the wheel hub and moving the wheel along the shaft to obtain the correct value.

Check if the wheel hub has been loosened and the wheel moved along the shaft.

A uniform radial gap is obtained by loosening the bearing bolts and set screws which will allow for correct repositioning.
