OUTDOOR: Fans designed for outdoor use may be stored
outdoors, if absolutely necessary. The storage area should
be reasonably level and drained or ditched to prevent
accumulation of water. Fencing and lighting for security are
desirable. Roads or aisles for portable cranes and hauling
equipment are needed. Consider the use of drift fencing to
minimize accumulation of blowing snow or dirt.
The following fans may be stored outdoors, if dry indoor
storage space is not available:
a. Fans intended for outdoor use that are crated in
wood.
b. Wall fans where installed in wall housings.
All fans must be supported on wooden blocks or timbers
above water or normal snow levels. Provide enough blocking
to prevent settling into soft ground. Fans should be set in
place using the directional arrow markings on the crate as a
guide.
Locate pieces far enough apart to permit air circulation,
sunlight, and space for periodic inspection. Place all parts
on their supports so that rain water will run off, or to minimize
water accumulation. Do not cover parts with plastic lm or
tarps - these cause condensation of moisture from the air
passing through heating and cooling cycles.
Fan wheels and propellers should be blocked to prevent
spinning caused by strong winds.
INSPECTION AND MAINTENANCE
DURING STORAGE
Inspect fans and accessories at least once per month, while
in storage. Log results of inspection and maintenance
performed. A typical log entry should include the following:
a. Date
b. Inspector’s Name
c. Name of Fan
d. Location
e. Condition of Paint or Coating
f. Is moisture present?
g. Is dirt accumulated?
h. Corrective steps taken?
If moisture or dirt accumulations are found on parts, the
source should be located and eliminated. Fans should be
rotated at each inspection by hand ten to fteen revolutions to
redistribute the motor and bearing lubricant.
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. The most
critical items are pulleys, shafts and bearing locking collars.
At the rst sign of rusting on any of the above parts, remove
the original rust preventive coating with petroleum solvent and
clean lint-free cloths. Polish any remaining rust from surfaces
with crocus cloth or ne emery paper and oil. Do not destroy
the continuity of the surfaces. Wipe clean with lint-free cloths
and recoat surfaces evenly and thoroughly with Tectly 506
(Ashland Oil Company) or equal. For hard to reach internal
surfaces or for occasional use, consider using Tectly 511M
Rust Preventive or WD40 or equal.
REMOVING FROM STORAGE
As fans are removed from storage to be installed in their nal
location, they should be protected and maintained in similar
fashion, until the fan equipment goes into operation.
INSTALLATION
1. CAUTION! This unit has rotating parts and safety
precautions should be exercised during installation,
operation and maintenance.
2. WARNING! Do not use in hazardous environments
where the fan's electrical system could provide ignition
to combustible or ammable materials, unless the unit is
specically built for hazardous environments.
3. WARNING! If gases, other than clean air, are to be
exhausted using the fan, then the user bears the
responsibility of determining that the fan is appropriate
and safe for the application.
4. COMMERCIAL KITCHEN EXHAUST APPLICATIONS:
Ventilators should be installed in accordance with the
requirements of the National Fire Protection Association
Bulletin NFPA96 “Vapor Removal From Cooking
Equipment” taking specic note of the following:
(a) Ducts terminating into the base of an up-discharge
exhaust fan shall be constructed of carbon steel not
less than 16 MSG (1.6 mm) and extend a minimum
of 18" (457 mm) above the roof surface.
(b) Air velocity through the duct shall not be less than
1500 FPM (7.620 m/s).
(c) A minimum of 40" (1016 mm) clearance shall be
maintained between the exhaust discharge and
the roof surface. (To comply sizes 80 through 300
require 18" [457 mm] roof curb.)
(d) Fan Discharge shall be a minimum of 10 feet from
the fresh air intake.
5. GREASE TROUGH ACCESSORY: A container to collect
residue grease should be located under the grease drain
on the ventilator to prevent accumulation of grease on the
roof surface. An accessory grease trough that attaches
to the curb is available from the manufacturer at extra
cost. Containers should be serviced at regular intervals
to prevent overow. Curb hinges are also available as an
optional accessory. Installation instructions are shipped
with the accessories.
