Receiving and Inspection
Carefully inspect the fan and accessories for any damage and shortage immediately upon receipt of the fan.
• Turn the wheel by hand to ensure it turns freely and
does not bind.
• Check dampers (if included) for free operation of all
moving parts.
• Record on the Delivery Receipt any visible sign of
damage.
Handling
Lift the fan by the base or by the shipping carton. Never
lift by the shaft, motor or housing.
Damper Installation
If your fan is supplied with dampers, follow the directions
below. If your fan does not include dampers, proceed to
Belt and Pulley Installation.
a. Place the damper inside the curb. Ensure the dam pe r
will open freely for the correct direction of the airflow.
b. Secure to curb at the damper shelf.
c. Drill a hole in the curb shelf for conduit needed for
motor wiring.
d. Operate the dampers manually to ensure the blades
move freely. Dampers should be released from full
open position to check for proper closing.
e. Install fan over curb with the conduit location in line
with the conduit hole in the curb.
Belt and Pulley Installation
Belt tension is determined by the sound of the belts when
the fan is first started. The belts will produce a loud squeal,
which dissipates after the fan is operating at full capacity. If
belt tension is too tight or too loose, lost efficiency and dam age can occur.
Do not change the pulley pitch diameter to change ten-
sion. The change will result in a different fan speed.
Storage
If the fan is stored for any length of time prior to installation, store it in its original shipping crate and protect it from
dust, debris and the weather.
Installation
To prevent damage to the fan during shipping, motors 5
HP and larger, and extremely heavy motors (cast iron or
severe duty) are shipped loose and must be field mounted
by bolting the motor on the motor mounting plate in the
existing mounting slots.

GAP
a. Loosen the motor plate adjustment bolts on motor base
and move motor plate in order that the belts can easily
slip into the grooves on the pulleys. Never pry, roll, or
force the belts over the rim of the pulley.
b. Adjust the motor plate until proper tension is reached.
For proper tension, a deflection of approximately 1/4”
per foot of center distance should be obtaine d by firmly
pressing the belt. Refer to Figure 1.
c. Lock the motor plate adjustment bolts in place.
d. Ensure pulleys are properly aligned. Refer to Figure 2.
Pulley Alignment
Pulley alignment is adjusted by loosening the motor pulley
setscrew and by moving the motor pulley on the motor shaft.
Figure 2 indicates where to measure the allowable gap
for the drive alignment tolerance. All contact points (indicated by WXYZ) are to have a gap less than the tolerance
shown in the table. When the pulleys are not the same
width, the allowable gap must be adjusted by half of the difference in width. Figure 3 illustrates using a carpenter’s
square to adjust the position of the motor pulley until the
belt is parallel to the longer leg of the square.
Refer to the Wiring Diagrams, next page.
Lock off all power sources before unit is
wired to power source.
Leave enough slack in the wiring to allow
for motor movement when adjusting belt tension. Some fractional motors have to be
removed in order to make the connection with
the terminal box at the end of the motor.
Figure 3
Follow the wiring diagram in the disconnect switch and
the wiring diagram provided with the motor. Correctly
label the circuit on the main power box and always
identify a closed switch to promote safety (i.e., red tape
over a closed switch).
Fan Installation
The fan support (roof curb) should provide a level surf ace
for installation. If the roof is pitched more than 1/2:12, a
sloped curb must be used to correct for the incline. Place
fan over roof opening. Secure the fan with lag screws,
anchor bolts, or other suitable fasteners.
For easier installation larger size fans may be disassembled on the ground and transported to the roof in sections.
However, if the sections are not assembled properly the
wheel may rub against the fan inlet causing noise.
This can be prevented by:
• Ensuring the wheel is tightly fastened on the shaft.
• Ensuring the wheel is not dropped on the shaft before
the setscrews are tightened.
Should interference occur, disconnect the power source.
Refer to Bearing Replacement on page 5.
Wiring Installation
All wiring should be in accordance with local ordinances
and the National Electrical Code, NFPA 70. Ensure the
power supply (voltage, frequency, and current carrying
capacity of wires) is in accordance with the motor nameplate.
Final Installation Steps
a. Inspect fasteners and setscrews, particularly fa n
mounting and bearing fasteners, and tighte n according
to the recommended torque shown in the table on page
4, Recommended Torque for Setscrews/Bolts.
b. Inspect for correct amperage and voltage with an
ammeter and voltmeter.
c. Ensure all accessories are installed.
d. Inspect wheel-to-inlet clearance on power roof fans.
e. Test the fan to be sure the rotation is the same as indi-
cated by the arrow marked Rotation.
Do not allow the fan to run in the wrong direction.
This will overheat the motor and cause serious damage. For 3-phase motors, if the fan is running in the
wrong direction, check the control switch. If is possible
to interchange two leads at this location so that the fan
is operating in the correct direction.

Pre-Start Checks
a. Lock out all the primary and secondary power sources.
b. Inspect fasteners and setscrews, particularly those
used for mounting the fan, and tighten if necessary.
c. Inspect belt tension and pulley alignment. (Remember,
if belt tension is correct, a loud squeal occurs as the
fan increases to full power.)
d. Inspect motor wiring.
e. Ensure the belt touches only the pulleys.
f. Ensure fan and ductwork are clean and free of debris.
g. Test the fan to ensure the rotation of the wheel is the
same as indicated by the rotation label.
h. Restore power to unit.
Start Up
Turn the fan on. In variable speed units, set the fan to its
lowest speed. Inspect for the following:
• Direction of rotation.
• Excessive vibration.
• Unusual noise.
• Bearing noise.
• Improper belt alignment or tension (listen for a continu-
ous squealing noise).
• Improper motor amperage or voltage.
If a problem is discovered, immediately shut off the
fan. Lock out all electrical power and check for the
cause of the trouble. Refer to Troubleshooting, page 6.
Inspection
Inspection of the fan should be conducted at the first 30
minute, 8 hour and 24 hour intervals of satisfactory opera-
tion. During the inspections, stop th e fa n a nd inspect as per
the chart below.
30 Minute Interval
Inspect bolts, setscrews, and motor mounting bolts.
Adjust and tighten as necessary.
8 Hour Interval
Inspect belt alignment and tension. Adjust and tighten as
necessary.
24 Hour Interval
Inspect belt tension. Adjust and tighten as necessary.
Maintenance
Establish a schedule for inspecting all parts of the fan.
The frequency of inspection depends on the operating conditions and location of the fan.
Inspect fans exhausting corrosive or contaminated air
within the first month of operation. Fans exhausting contaminated air (airborne abrasive s) should be inspected
every three months. Clean the wheel and air inlets if material build-up is excessive. Excessive build-up can cause
imbalance and failure of the wheel.
Regular inspections are recommended for fans exhausting non-contaminated air.
It is recommended the following inspections be conducted twice per year.
• Inspect bolts and setscrews for tightness. Tighten as
necessary.
• Inspect belt wear and alignment. Replace worn belts
with new belts and adjust alignment as needed. See
Belt and Pulley Installation, page 1.
• Bearings should be inspected as recommended in the
Conditions Chart, page 5.
• Inspect for cleanliness. Clean exterior surfaces only.
Removing dust and grease on motor housing assures
proper motor cooling.
Fan Bearings
The fan bearings are provided prelubricated. Any specialized lubrication instructions on fan labels supercedes
information provided herein. Bearing grease is a petrole um
lubricant in a lithium base conforming to a NLGI #2 consistency. If user desires to utilize another type of lubricant,
they take responsibility for flushing bearings and lines, and
maintaining a lubricant that is compatible with the installation.
A NLGI #2 grease is a light viscosity, low-torque, rustinhibiting lubricant that is water resistant. Its temperature
range is from -30°F to 200°F and capable of intermittent
highs of 250°F.
Bearings should be relubricated in accordance with the
condition chart below.
For best results, lubricate the bearing while the fan is in
operation. Pump grease in slowly until a slight bead forms
around the bearing seals. Excessive grease can damage
seal and reduce life through excess contamination and/or
loss of lubricant.
In the event that the bearing cannot be seen, use no
more than three injections with a hand operated grease
gun.

Motors are provided with prelubricated bearings. Any
lubrication instructions shown on the motor nameplate
supersede instructions below.
Direct Drive 1050/1075,1200,1300 &1500 rpm units use
a prelubricated sleeve bearing that has a oil saturated wicking material surrounding it. The initial factory lubrication is
adequate for up to 10 years of operation under n ormal conditions. However, it is advisable to add lubricant after 3
years. Use only LIGHT grade mineral oil or SAE 10W oil up
to 30 drops. If the unit has been stored for a year or more it
is advisable to lubricate as directed above. For VCR direct
drive units and other units in severe conditions, lubr ication
intervals should be reduced to half.
Motors without sleeve bearings (as described above) wi ll
have grease lubricated ball or roller bearings. Motor bearings without provisions for relubrication will operate up to
10 years under normal conditions with no maintenance. In
severe applications, high temperatures or excessive contaminates, it is advisable to have the maintenance department disassemble and lubricate the bear ing s after 3 years
of operation to prevent interruption of service.
For motors with provisions for relubrication, follow intervals of the table below.

Motor Services
Should the motor prove defective within a one -ye a r
period, contact your local Loren Cook representative or
your nearest authorized electric motor service representative.
Changing Shaft Speed
All belt driven fans with motors up to and including 5HP
are equipped with variable pitch pulleys. To change the fan
speed, perform the following:
a. Loosen setscrew on driver (motor) pulley and remove
key, if equipped.
b. Turn the pulley rim to open or close the groove facing.
If the pulley has multiple grooves, all must be adjusted
to the same width.
c. After adjustment, inspect for proper belt tension.
Speed Reduction
Open the pulley in order that the belt rides deeper in the
groove (smaller pitch diameter).
Pulley and Belt Replacement
a. Clean the motor and fan shafts.
b. Loosen the motor plate mounting bolts to relieve the
belt tension. Remove the belt.
c. Loosen the pulley setscrews and remove the pulleys
from the shaft.
If excessive force is required to remove the pulleys,
a three-jaw puller can be used. This tool, however, can easily war p a pulley . If the p uller is used,
inspect the trueness of the pulley after it is
removed from the shaft. The pulley will need
replacement if it is more than 0.020 inch out of
true.
d. Clean the bores of the pulleys and place a light coat of
oil on the bores.
e. Remove grease, rust and burrs from the shaft.
f. Place fan pulley on the fan shaft and the motor pulley
on the motor shaft. Damage to the pulleys can occur
when excessive force is used in placing the pulleys on
their respective shafts.
g. After the pulleys have been correctly placed back onto
their shafts, tighten the pulley setscrews.
h. Install the belts on the pulleys. Align and adjust the
belts to the proper tension as described in Belt and
Pulley Installation, page 1.
Bearing Replacement
The fan bearings are pillow block ball bearings.
a. Loosen screws on bearing cover.
b. Push bearing cover toward the wheel. As the bearing
cover moves toward the wheel it will slide down to
reveal the bearings and shaft.
c. Remove the old bearing.
d. Remove any burrs from the shaft by sanding.

tion and loosely mount bearings onto the bearing support. Bearing bolts and setscrews should be loose
enough to allow shaft positioning.
f. Correctly position the wheel and tighten the bearing
bolts securely to the bearing support.
g. Align setscrews bearing to bearing and secure tightly to
the shaft.
Never tighten both pairs of sets crews before securing bearing mounting bolts. This may damage the
shaft.
h. Inspect the wheel position again. If necessary, readjust
by loosening the bearing bolts and setscrews and
repeat from step e.
Wheel Replacement
a. Drill two holes approximately centered between the
shaft and the edge of the hub OD with the following
dimensions:
• 1/4" diameter
• 3/8" to 1/2" deep
• 180° apart in face of hub
b. Tap 1/4" holes to 5/16" thread with the 5/16" hole tap.
Do not drill or tap any larger than recommended.
c. Screw the puller arms into the tapped holes full depth of
threads (3/8" to 1/2" approximately). Align center of
puller with center of shaft. Make certain all setscrews in
hub (normally a quantity of two) are fully removed.
Work puller slowly to back wheel of f the shaft.
Recommended Puller
Lisle No. 45000 Sterling Wheel Puller. This puller is available at most automotive parts retail outlets.
A uniform radial gap (space between the edge of the cone
and the edge of the inlet) is obtained by loosening the inlet
cone bolts and repositioning the inlet cone.

inlet.
•Improper wheel alignment.
Excessive Vibration and Noise
•Damaged or unbalanced wheel.
•Belts too loose; worn or oily belts.
•Speed too high.
•Incorrect direction of rotation. Make sure the fan rotates in same direction as the arrows on the motor or belt drive assembly.
•Bearings need lubrication or replacement.
•Fan surge.
Overheated Motor
•Motor improperly wired.
•Incorrect direction of rotation. Make sure the fan rotates in same direction as the arrows on the motor or belt drive assembly.
•Cooling air diverted or blocked.
•Improper inlet clearance.
•Incorrect fan RPMs.
•Incorrect voltage.
Overheated Bearings
•Improper bearing lubrication
•Excessive belt tension.
Wheel-to-Inlet Clearance
The correct wheel-to-inlet clearance is critical to proper
fan performance. This clearance should be verified before
initial start-up since rough handling during shipment could
cause a shift in fan components. Refer to wheel/inlet drawing for correct overlap.
Adjust the overlap by loosening the wheel hub and moving the wheel along the shaft to obtain the correct value.
