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’srepresentativeshouldnotaccepta
shipment without a notation on the delivery receipt
indicating items not delivered or the apparent extent of
damage.
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 dehumidifier to remove moisture from the air
in the storage enclosure.
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 orifices
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 uponreceipt certain precautionsare
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
Thermostatically controlled portable heaters (vented to
outdoors)mayberequiredtomaintaineven
temperatures inside the enclosure.
CAUTION! Provide fire extinguishers, or fire alarms, or
emergency response communication to protect building
and equipment against fire damage.Be sure that
building and storage practices meet all local, state and
federal fire 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 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 floor 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 film or tarps-these cause condensation of
moisture from the air passing through heating and
cooling cycles.
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 fine 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
final 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 fan’s electrical system could provide ignition to
combustible or flammable materials, unless the unit
is specifically built for hazardous environments.
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 fifteen
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 first sign of rusting on any
3. The fan should be mounted on a solid foundation
equipped with anchoring devices (such as anchor
bolts). Level the fan on the foundation, shimming
where necessary.Anchor the fan securely to the
foundation.If vibration isolators are used, these
should be installed between the fan and the
foundation. When mounted on suspended platforms
adequate cross bracing will be required.
4. Check pulley alignment and belt tension. Belt should
deflect ½" to 3/4" (13mm to 19mm) when depressed
by hand midpoint between pulleys.
5. CAUTION! Before proceeding, make sure electrical
service to fan is locked in “OFF” position.
6. All wiring should be in accordance with local
ordinances and the National Electric Code.
7. 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.
8. Apply power momentarily and compare the rotation
of the impeller with directional arrow on fan. In the
case of three phase motors, the direction can be
reversed by interchanging any two of the three motor
leads.In the case of single phase motors, the
reversing instructions appear on the wiring diagram
in the motor wiring compartment.

9.WARNING! Operation in the wrong direction will
deliver air but will overload the motor and could
seriously damage the motor.
maintenance may be required as often as once a
month.Regularmaintenanceshouldinclude
inspection and cleaning of all fan parts.
10.OUTDOORS When installed outdoors, units should
be provided with Weather Covers available as an
optional accessory from the Company.Outlet
dampers attached to the fan discharge should be
normally closed when the fan is not running.
11.CAUTION! Inlet guards (available from the company
as optional equipment) must be installed whenever
the fan is installed without ducts attached to the fan
inlet.
12.CAUTION! Guards must be installed when fan is
within reach of personnel or within seven (7) feet
(2.134m) of working level or when deemed advisable
for safety.
13.IMPELLER-INLETVENTURIADJUSTMENT
Adjustment can be achieved through the use of the
slotted holes provided in the fan construction.
For vertical movement, adjust the bearing base
support up or down on the side plates of the motor
and drive compartment. After any adjustment, the
bearing base should be checked to assure its being
level.
For horizontal movement the lower half of the duplex
split pillow bearing housing is slotted for sideways
adjustment. By loosening either set of these bolts,
the impeller can be moved to provide running
clearance between it and the inlet venturi. Be sure to
re-tighten all bolts after proper clearances are
obtained.
MAINTENANCE
1.Undernormalusage,nosparepartsare
recommendedforoneyearofoperation.
Recommended spare parts are shown on page 4.
2.CAUTION!Before proceeding, make sure the
electrical service to the fan is locked in “OFF”
position.
WINDMILLING:Even when the power supply is
locked out, fans may cause injury or damage if the
impeller is subject “windmilling” which is the turning
of the impeller and drive components due to a draft
in the system.To guard against this hazard, the
impeller should be secured to physically restrict
rotational movement.
3.REGULAR MAINTENANCE Determined by the
condition of the air passing through the fans,
regularly scheduled inspection of all fan parts
establishes a good maintenance routine. When the
air is clean, maintenance can be as infrequent as
onceayear.Whenairiscontaminated,
4. Check belt tension after first 48 hours of operation
and thereafter annually.Belt should depress its
width when pressed firmly inward at midway point
between the pulleys. Too much tension will damage
bearings.Belt should be tight enough to prevent
slippage. When replacing worn belt, replace motor
pulley if “shoulder” is worn in groove.For 2 belt
drives, be sure to replace both belts with a matched
set. Do not adjust belts too tightly as this will cause
undue wear on the bearings of both fan and motor.
Motor pulleys should be inspected regularly and
replaced if they show evidence of excessive wear or
“grooving”.
WARNING! Do not operate at speeds higher than
that cataloged for this equipment. Do not replace
motor pulley with a larger diameter pulley. Do not
replace the fan pulley with one smaller in diameter.
The pulley ratios are set so that the motor will not be
overloaded.
5. Impeller shaft bearings on units with duplex split
pillow block housing are prelubricated and do not
require relubrication. Units with pillow block bearings
have grease fittings and, under normal operation will
need no relubrication for 3 to 5 years. If relubrication
is required, use a grease conforming to NLGI No. 2.
CAUTION! Lubricating bearings with a high pressure
gun can blow bearing seals and overfill the bearing
with grease. This condition can result in excessive
churning and over heating.For normal operating
conditions it is standard practice to fill only 30% of
the bearing void with grease. Do not over lubricate.
NOTE: If locking collar type bearing is used, collar
must first be positioned against inner race on bearing
nearest impeller and turned in direction of impeller
rotation with drift pin and hammer until it locks.
Locking collars must be on inboard (facing) sides of
the bearings. Secure bearing to shaft with set screw.
Lock and secure other bearing to shaft in same
manner.
NOTE: If pillow block type bearings are used, slide
bearings onto the shaft to desired location and bolt
bearing block securely to support base. Slide shaft
back and forth in secured bearing (do not drive with
hammer) and rotate to make certain it turns freely.
Check correct position of impeller with inlet orifice.
Then secure bearings to shaft by tightening set
screws.
