Rotating Parts & Electrical Shock Hazard:
Disconnect electric power before working on unit.
Follow proper lockout / tagout procedures to ensure
the unit cannot be energized while being installed or
serviced.
A disconnect switch should be placed near the fan in
order that the power can be swiftly cut off, in case of
an emergency and in order that maintenance
personnel are provided complete control of the power
source.
Grounding is required. All field-installed wiring must
be completed by qualified personnel. All fieldinstalled wiring must comply with National Electric
Code (NFPA 70) and all applicable local codes.
Failure to follow these instructions could result in
death or serious injury.
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.
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.
The attachment of roof mounted fans to the roof curb
as well as the attachment of roof curbs to the building
structure must exceed the structural requirements
based on the environmental loading derived from the
applicable building code for the site. The local code
official may require variations from the recognized
code based on local data. The licensed engineer of
record will be responsible for prescribing the correct
attachment based on construction materials, code
requirements and environmental effects specific to
the installation.
Failure to follow these instructions could result in
death or serious injury.
Dampers
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 damper
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.
Handling
Lift the fan by the base or by the shipping carton.
NOTICE! Never lift by the shaft, motor or housing.
HLC
Belt and Pulley Installation
1 foot
1/4 inch
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
damage can occur.
Do not change the pulley pitch diameter to change
tension. The change will result in a different fan speed.
Belt and Pulley
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 obtained by firmly
pressing the belt. Refer to Figure 1.
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.

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.
Refer to the Wiring Diagrams, next page.
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.
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 surface
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.
Final Installation Steps
a. Inspect fasteners and setscrews, particularly fan
mounting and bearing fasteners, and tighten 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
indicated by the arrow marked Rotation.
NOTICE! 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.

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
continuous squealing noise).
• Improper motor amperage or voltage.
NOTICE! 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
operation. During the inspections, stop the fan and 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 abrasives) 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.
• Inspect for cleanliness. Clean exterior surfaces only.

Fan Bearings
The fan bearings are provided prelubricated. Any
specialized lubrication instructions on fan labels
supersedes information provided herein. Bearing grease is
a petroleum 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.
Motor Bearings
Motors are provided with prelubricated bearings. Any
lubrication instructions shown on the motor nameplate
supersede instructions below.
4
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 normal 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 direct drive units and other units in severe conditions,
lubrication intervals should be reduced to half.
Motors without sleeve bearings (as described above) will
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 bearings after 3
years of operation to prevent interruption of service.
For motors with provisions for relubrication, follow
intervals of the table below.

Motors are provided with a polyurea mineral oil NGLI #2
grease. All additions to the motor bearings are to be with a
compatable grease such as Exxon Mobil Polyrex EM and
Chevron SRI.
The above intervals should be reduced to half for vertical
shaft installations.
Motor Services
Should the motor prove defective within a one-year
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).
Speed Increase
Close the pulley in order that the belt rides higher in the
groove (larger pitch diameter). Ensure that the RPM limits
of the fan and the horsepower limits of the motor are
maintained.

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 warp a pulley. If the puller 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.
e. Slide new bearings onto the shaft to the desired loca-
tion and loosely mount bearings onto the bearing sup-
port. 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.
5
g. Align setscrews bearing to bearing and secure tightly
to the shaft. NOTICE! Never tighten both pairs of
setscrews 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 off the shaft.
Recommended Puller
Lisle No. 45000 Sterling Wheel Puller. This puller is available at most automotive parts retail outlets.

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.
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.
