Swing Out Door
All moving parts that require maintenance are mounted
on a hinged door that opens to provide easy access.
• Disconnect power to the unit.
• Clear area around door to allow it to swing open.
• Remove locking pin(s) from door (door latches may
have to be loosened slightly).
• Loosen restraining bolts located at the top and bottom
of door.
• Loosen and remove door latches in steps to insure
even opening of door.
• Pull door open.
• Reverse the steps above to close door.
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.
