Removing from Storage
As fans are removed from storage to be installed in their
final location, they should be protected and maintained
in a similar fashion until the fan equipment goes into
operation.
Prior to assembly and installation of the unit and system
components, inspect the fan assembly to make sure it is
in working order.
1. Check all fasteners, set screws on the fan, wheel,
bearings, drive, motor base and accessories for
tightness.
2. Rotate the fan wheel by hand and assure no parts
are rubbing. Access to the wheel is obtained through
a bolted panel located on the side of the fan housing.
3. Ensure proper wheel settings for radial gap and
alignment. Refer to Radial Gap, Overlap and Wheel
Alignment section on page 10.
