Table Of Contents; Removing From Storage - Greenheck USF-200 Installation, Operation & Maintenance Manual

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 506 (Ashland Inc.) or the
equivalent. For hard to reach internal surfaces or for
occasional use, consider using Tectyl
Preventive, WD-40 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 9.
