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.
3. Ensure wheel backplate is equidistant from inlet cone
ID on both sides (in case of double-wide wheel) for
proper wheel centering.
