RECEIVING AND INSPECTION
Immediately upon receipt of a shipment, carefully inspect
for damage and shortage. Turn the impeller by hand to see
that it turns freely and does not bind. If any damage and/or
shortage is detected or suspected, the carrier must be asked
to conduct an inspection. The consignee’s representative
should not accept a shipment without a notation on the
delivery receipt indicating items not delivered or the apparent
extent of damage.
When a shipment is opened and damage is found which was
not evident externally (concealed damage), it is mandatory
that the consignee request an immediate inspection by the
carrier. Report any damage to the carrier within 15 days.
Failure to report damage within the above time limit will result
in rejection of a claim.
HANDLING
When handling fans and their accessories, always use
equipment and methods that will not cause damage. Fans
should be lifted using slings and padding or spreaders to
avoid damage.
CAUTION! Always make sure that all lifting and handling
equipment and techniques conform to current safety
standards.
Avoid lifting fans in a way that will bend or distort fan parts.
Never pass slings or timbers through the orices of fan.
CAUTION! Do not lift by the fan hood. Fans with special
coatings or paints must be protected in handling to prevent
damage.
STORAGE
Fans are protected against damage during shipment. If
they cannot be installed and put into operation immediately
upon receipt certain precautions are necessary to prevent
deterioration during storage. Responsibility for integrity of
fans and accessories during storage must be assumed by the
user. The manufacturer will not be responsible for damage
during storage. These suggestions are provided solely as a
convenience to the user, who shall make his own decision as
to whether to use any or all of them.
INDOOR: The ideal storage environment for 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
at between 70°F and 105°F (wide temperature swings may
cause condensation and “sweating” of metal parts). Windows
should be covered to prevent temperature variations caused
by sunlight. Provide thermometers and humidity indicators at
several points and maintain the atmosphere at 40% relative
humidity, or lower.
It may be necessary to use trays of renewable desiccant or
portable dehumidier to remove moisture from the air in the
storage enclosure.
Thermostatically controlled portable heaters (vented to
outdoors) may be required to maintain even temperatures
inside the enclosure.
CAUTION! Provide re extinguishers, or re alarms, or
emergency response communication to protect building and
equipment against re damage. Be sure that building and
storage practices meet all local, state and federal re and
safety codes.
The following fans or accessories must be stored indoors, in
a clean dry atmosphere:
a. Propeller wall fans not in wall housings.
b. Any fan is protected by a cardboard carton.
c. Motors dismounted from fans.
d. Spare wheels or propellers.
e. Belts, sheaves, bushings and other parts when not
mounted on fan.
f. Boxes, bags or cartons of hardware.
g. Curbs
h. Dampers
Remove any accumulations of dirt, water, ice or snow and
wipe dry before moving indoor storage. Allow cold parts to
reach room temperature to avoid “sweating” of metal parts.
Open boxes or cartons. Remove any accumulated moisture;
if necessary use portable electric heaters to dry parts and
packages. Leave coverings loose to permit air circulation and
to permit periodic inspection.
Rotate wheels or propellers by hand to distribute bearing
grease over the entire bearing surfaces.
Store at least 3 ½” off the oor on wooden blocks covered
with moisture proof paper or polyethylene sheathing. Provide
aisles between parts and along all walls, to permit air
circulation and space for inspection.
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 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
For the PRN Model with hurricane construction that complies
with Florida Building Code including High Velocity Hurricane
Zones (HVHZ) see the ADDITIONAL INSTALLATION AND
MAINTENANCE INSTRUCTIONS on page 4.
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. If the fan manufacturers prefab curb is used, a ange is
provided for mounting the damper. Damper should be
installed before setting exhauster.
5. If damper box is being used, assemble box and mount in
curb before setting exhauster. Damper may be installed
at this time if desired. Damper should be fastened to the
bottom of the damper box, curb anges or nailing strips in
curb.
6. Impeller Adjustment: Turn centrifugal impeller by hand to
make sure it rotates freely. If impeller hits orice, adjust
by loosening set screw in impeller hub and move impeller
back on motor shaft.
7. CAUTION! Guards must be installed when fan is within
reach of personnel or within eight (8) feet (2.5 m) of
working level or when deemed advisable for safety.
8. Remove the motor compartment cover (small hood).
CAUTION! Before proceeding, make sure electrical
service to fan is locked in “OFF” position. Run wires
through the internal wiring post to the motor, to disconnect
switch if used. WARNING! The wiring post is sealed to the
curb cap with a large washer and sealing gasket. If the
wiring post is loosened, the seal may be broken, thereby
creating a possible water leak.
9. All wiring should be in accordance with local ordinances
and the National Electric Code.
For EC Motor Wiring
See form 613084 for wiring diagrams on EC Motors
10. WARNING! Check voltage at the fan to see if it
corresponds with the motor nameplate. High or low
voltage can seriously damage the motor. Extra care
should be taken when wiring two speed motors since
improper connections will damage motor and void motor
warranty.
