Machined parts coated with rust preventive should be
restored to good condition promptly if signs of rust
occur. Immediately remove the original rust preventive
coating with petroleum solvent and clean with lint-free
cloths. Polish any remaining rust from surface with
crocus cloth or fine emery paper and oil. Do not destroy
the continuity of the surfaces. Thoroughly wipe clean
with Tectyl

or the equivalent.
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 8.
