RECEIVING AND INSPECTION
humidity indicators at several points and maintain the
atmosphere at 40% relative humidity, or lower.
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 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 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
It may be necessary to use trays of renewable desiccant or
portable dehumidifier 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 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.
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 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.
2. WARNING! Do not use in hazardous environments where
the fan’s electrical system could provide ignition to
combustible or flammable materials, unless the unit is
specifically built for hazardous environments.
3. Impeller Adjustment: Turn centrifugal impeller by hand to
make sure it rotates freely. If impeller hits orifice, remove
side panel (both sides are removable) and motor or drive
enclosure panel as in shown Figure1.
Figure 1
Adjustment is made as follows:
4.
Direct Driven Units
Loosen bolts holding the motor to the mounting frame.
This will allow free movement of the impeller in all
directions for adjustment. Do not loosen the set screws in
the impeller hub since this will only allow movement in or
out on the motor shaft. Tighten all bolts before operating
the unit.
Belt Driven Unit
The bearing support base and the bearing lower housing
are slotted for adjustment. Loosen the bolts indicated in
Figure 2 and center the impeller over the orifice. Tighten
all bolts before operating the unit.
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. These units are not air tight and should not be used where
escape of contaminated air would cause problems.
CAUTION! This unit has rotating parts and safety
precautions should be exercised during installation,
operation and maintenance.
Page 2
Figure 2
Belt drive units are shipped without the sheaves mounted.
5.
Remove the sheaves from the drive package and install
on the fan. The rear cover is removable if required.
6. Check the pulley alignment and belt tension. Adjust the
belt tension using motor base jack screws. Belt should
depress its width when pressed firmly inward at midway
point between the pulleys. Replace all panels and tighten
corresponding bolts.
7. If unit is to be equipped with isolators and/or support
brackets they should be attached at this time using the
mounting instructions (Form 613101) included with them.
8. Securely support the unit and attach the duct work.
9. Units used outdoors should be installed to provide
maximum weather protection. Direct driven units should
be positioned so that the breather tube to the motor
compartment will not let moisture enter. Belt driven units
should include a motor cover to protect the motor and belt
enclosure opening from moisture.
10. CAUTION! Before proceeding, make sure electrical
service to the fan is locked in the “OFF” position.
11. All wiring should be in accordance with local ordinances
and the National Electric Code.
12. WARNING! Check the 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 the motor and void the
motor warranty. On belt driven units, leave enough slack
in wiring to allow for motor movement when adjusting belt
tension.
13. Apply power momentarily and compare the rotation of the
impeller with the directional arrow on fan. WARNING!
Operation in the wrong direction will deliver air but will
overload the motor to the extent of blowing fuses and
seriously damaging the motor. In the case of three phase
motors, the direction can be changed by interchanging
any two of the three motor leads. In the case of single
phase motors, the reversing instructions will appear on the
wiring diagram in the motor wiring compartment.
14. CAUTION! Guards must be installed when the fan is
within reach of personnel or within eight (8) feet (2.5m) of
working level or when deemed advisable for safety.
MAINTENANCE
1. Under normal usage, no spare parts are recommended for
one year of operation. Recommended spare parts are
shown on Pages 6 and 7.
2. CAUTION! Before proceeding, make sure electrical
service to the fan is locked in the “OFF” position.
WINDMILLING: Even when the power supply is locked
out, fans may cause injury or damage if the impeller is
subject to “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. Acme Duplex Split pillow block bearings are prelubricated
and do not require relubrication. Units with pillow block
bearings have grease fittings and, under normal operating
conditions, 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 overheating. For normal operating conditions
it is standard practice to fill only 30% of the bearing void
with grease. Do not over lubricate.
4. Motor bearings are prelubricated. Consult information
printed on the motor for lubrication instructions.
5. On belt driven units, check belt tension after the 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
the bearings. The belt should be tight enough to prevent
slippage. When replacing a worn belt, replace the motor
pulley if “shoulder” is worn in groove. WARNING! Do not
replace the 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. Do not operate at higher speeds than that
cataloged for this equipment.
6. If it should become necessary to remove the impeller, first
remove the motor and impeller or shaft, bearing and
impeller assembly.(See Figure 1) On model sizes 120,
137 and 161 there is a sleeve which fits inside the impeller
hub. To remove the impeller from the shaft, completely
remove the two socket head cap screws that go through
the sleeve. The impeller will then slide off the sleeve and
the set screws attaching the sleeve can be loosened
allowing its removal. The impellers on larger size units are
attached with a roll pin. Remove the roll pin by driving it
out with a drift pin.
7. On belt driven units: If impeller shaft bearings need
replacement, replace with bearing comparable to the
original equipment. If Acme Duplex Split pillow block
bearings are used, install new bearings into neoprene
rings, check correct position of impellers with orifice,
position bearings in the die-formed recess and tighten the
set screws. Replace the die-formed bearing cap and
tighten the four bolts.
NOTE: If locking collar type bearing is used, collar must
first be positioned against the inner race on the bearing
nearest the impeller and turned in the direction of impeller
rotation with a drift pin and hammer until it locks. Locking
collars must be on the inboard (facing) sides of the
bearings. Secure the bearing to the shaft with set screws.
Lock and secure the other bearing to the shaft in the same
manner.
NOTE: If pillow block type bearings are used, slide
bearings onto 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
propeller with inlet orifice. Then secure bearings to shaft
by tightening set screws.

VARIABLE FREQUENCY
DRIVES AND MOTORS
There are occasions when a Variable Frequency Drive (VFD)
will cause poor motor performance and possible damage. To
avoid these problems, the Company recommends the
following:
1. Select compatible motor and VFD inverter; if possible, the
motor and the inverter should be from the same
manufacturer or at least the inverter selected should be
recommended by the motor manufacturer.
2. A motor shaft grounding system should be used to prevent
motor bearing damage from eddy currents.
NOTE: The Company will not honor motor warranty
claims if the customer fails to follow these recommendations.
Wiring Diagram for EC Motors
When XD fans are used with EC Motors and the optional remote speed control, the following wiring diagram should be
observed. A 120/24 VAC transformer will be added to the fan assembly for the purpose of powering the logic circuits in both
the motor and the remote speed control. The remote speed control will output a DC signal that varies from 0 to 10V. This
signal will vary the motor speed. All 120V connections will be made in the supplied junction box. Wire to the remote speed
control is to be supplied by others and must meet all applicable codes. The remote speed control location is limited by a
maximum wire length of 100 feet. Up to 6 fans can be operated from one remote control. Only one transformer should be
used. The 0-10 VDC (red) wires should be connected together, the common (white) wires should be connected together, and
the 24 VAC (black) should be connected together.
To use the remote variable speed control the speed control on the motor (if present) should be set full clockwise.
