INSTALLATION & MAINTENANCE INSTRUCTIONS
Models XB, XD, USB and USD
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 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 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.
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
Page 2
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.
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.
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
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.
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.
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
Page 2
Page 3
4. Adjustment is made as follows:
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.
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.
Figure 2
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.
5. Belt drive units are shipped without the sheaves
mounted. 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.
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. 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 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.
Page 3
Page 4
4. Motor bearings are prelubricated. Consult
information printed on the motor for lubrication
instructions.
2. After 500 operating hours or three months,
whichever comes first, tighten set screws to the full
recommended torque.
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 duplex split pillow block
bearings are use and 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.
3. At least once a year, tighten set screws to the full
recommended torque.

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 converter; if
possible, the motor and the converter should be from
the same manufacturer or at least the converter
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.
SET SCREW TIGHTENING SCHEDULE
1. Before initial operation of the fan, tighten set screws
according to the procedure outlined below.

NOTE: The Company will not honor motor warranty
claims if the customer fails to follow these
recommendations.
