Storage
Fans are protected against damage during shipment.
If the unit cannot be installed and operated
immediately, precautions need to be taken to prevent
deterioration of the unit during storage. The user
assumes responsibility of the fan and accessories
while in storage. The manufacturer will not be
responsible for damage during storage. These
suggestions are provided solely as a convenience to
the user.
Indoor
The ideal environment for the storage of fans and
accessories is indoors, above grade, in a low humidity
atmosphere which is sealed to prevent the entry of
blowing dust, rain or snow. Temperatures should be
evenly maintained between 30° to 110°F (-1° to 43°C)
(wide temperature swings may cause condensation
and "sweating" of metal parts). All accessories must
be stored indoors in a clean, dry atmosphere.
Remove any accumulations of dirt, water, ice or snow
and wipe dry before moving to indoor storage. To
avoid "sweating" of metal parts, allow cold parts to
reach room temperature. To dry parts and packages,
use a portable electric heater to get rid of any
moisture buildup. Leave coverings loose to permit air
circulation and to allow for periodic inspection.
The unit should be stored at least 3½ inches (89 mm)
off the floor on wooden blocks covered with moisture
proof paper or polyethylene sheathing. Aisles between
parts and along all walls should be provided to permit
air circulation and space for inspection.
Outdoor
Fans designed for outdoor applications may be stored
outdoors, if absolutely necessary. Roads or aisles for
portable cranes and hauling equipment are needed.
The fan should be placed on a level surface to prevent
water from leaking into the fan. The fan should be
elevated on an adequate number of wooden blocks
so that it is above water and snow levels and has
enough blocking to prevent it from settling into soft
ground. Locate parts far enough apart to permit air
circulation, sunlight and space for periodic inspection.
To minimize water accumulation, place all fan parts on
blocking supports so that rain water will run off.
Do not cover parts with plastic film or tarps as these
cause condensation of moisture from the air passing
through heating and cooling cycles.
Fan wheels should be blocked to prevent spinning
caused by strong winds.

Inspection and Maintenance during
Storage
While in storage, inspect fans once per month. Keep a
record of inspection and maintenance performed.
If moisture or dirt accumulations are found on parts,
the source should be located and eliminated. At each
inspection, rotate the wheel by hand ten to fifteen
revolutions to distribute lubricant on motor. If paint
deterioration begins, consideration should be given
to touch-up or repainting. Fans with special coatings
may require special techniques for touch-up or repair.
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.
