The correct wheel-to-inlet clearance is critical to proper
fan performance. This clearance should be verified
before initial start-up since rough handling during
shipment could cause a shift in fan components. Refer
to wheel/inlet drawing for correct overlap.
Adjust the overlap by loosening the wheel hub and
moving the wheel along the shaft to obtain the correct
value.
A uniform radial gap
(space between the
edge of the cone and
the edge of the inlet) is
obtained by loosening
the inlet cone bolts and
repositioning the inlet
cone.
