Handling
Fans are to be rigged and moved by the lifting brackets
provided or by the skid when a forklift is used. Location
of brackets varies by model and size. Handle in such
a manner as to keep from scratching or chipping the
coating. Damaged finish may reduce the ability of the
fan to resist corrosion. Fans should never be lifted by
the shaft, fan housing, motor, belt guard, windband or
accessories.
Storage
• Rotate fan wheel monthly and purge bearings once
every three months
• Energize fan motor once every three months
• Store belts flat to keep them from warping &
stretching
• Store unit in location which does not have vibration
• After storage period, purge grease before putting
fan into service
If storage of fan is in a humid, dusty or corrosive
atmosphere, rotate the fan and purge the bearings once
a month. Improper storage which results in damage to
the fan will void the warranty.
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.
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°F (-1°C) and
110°F (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 build
up. Leave coverings loose to permit air circulation and
to allow for periodic inspection.
The unit should be stored at least 3½ in. (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.
Inspection & 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. Wipe clean thoroughly
®
with Tectyl 506 (Ashland Inc.) or the equivalent.
For hard to reach internal surfaces or for occasional
use, consider using Tectyl
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 fully assembling and installing the fan and
system components, inspect the fan assembly to make
sure it is in working order.
1. Check all fasteners, set screws, wheel, bearings,
drive, motor base and accessories for tightness.
2. Rotate the fan wheel by hand and assure not
parts are rubbing. Access to the wheel is obtained
through an access panel located on the side of the
fan housing.
3. Ensure proper wheel settings for radial gap and
alignment. See pages 9-10.
