available in 115, 230 and 460 volt models. The damper motor nameplate
voltage should be verified prior to connection. **A transformer may be provided in some installations to correct the damper motor voltage to the
specified voltage.
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. To
remove motor , remove bolts se curing motor base to power
assembly. Do not remove motor mounting bolts.
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).

If your fan is a direct drive, proceed to Blower Installa-
tion.
Belt tension is determined by the sound the belts make
when the fan is first started. Belts will produce a loud
squeal which dissipates after the fan is operating at full
capacity. If the belt tension is too tight or too loose, lost efficiency and possible damage can occur.
Do not change the pulley pitch diameter to change tension. This will result in a different fan speed.
a. Loosen motor plate adjustment nuts on L-bolts 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 Figure1.
c. Lock the motor plate adjustment nuts in place.
d. Ensure pulleys are properly aligned. Refer to Figure

Upon receiving a SQN for a side discharge installation,
please note that the rear discharge block-off panel is
installed on the unit and that the cor rect number of side discharge duct connection collars are provided (4 steel
flanges for a single side discharge and 8 for dual).
To install the side discharge duct connection collar,
remove the appropriate access door. Install the side discharge duct connection collar using the bolts that were
removed with the access door . Then connect the duct work.
See page 5 for examples.
Final Installation Steps
a. Ensure that all accessories are installed.
b. Ensure that the blower is secured to ductwork.
c. Inspect wheel-to-inlet clearance. Ensure wheel does
not rub against the inlet.
d. Test the fan to ensure the rotation of the wheel is the
same as indicated by the rotation label.
e. Inspect for correct amperage with an ammeter and
correct voltage with a voltmeter.
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. It is possible to interchange two leads at this location so that the
fan is operating in the correct direction.
Operation
Pre-Start Checks
a. Lock out all the primary and secondary power
sources.
b. Inspect and tighten fasteners and s etscrews, particu-
larly fan mounting and bearing fasteners. Refer to
Torque chart.
c. Inspect belt tension and pulley alignment.
d. Inspect motor wiring.
e. Ensure fan and ductwork are clean and free of
debris.
f. Close and secure all access doors.
g. Restore power to the fan.
Start Up
Turn the fan on. In variable speed units, set the fan to its
lowest speed and inspect for the following:
• Direction of rotation.
• Excessive vibration.
• Unusual noise.
• Bearing noise.
• Improper belt alignment or tension (listen for squealing).
• Improper motor amperage or voltage.
If a problem is discovered, immediately shut the fan
off. Lock out all electrical power and check for the
cause of the trouble. See Troubleshooting on page 7.
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 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.
Yearly 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. Refer to Torque chart.
• Inspect belt wear and alignment. Replace worn belts

• Inspect for cleanliness. Clean exterior surfaces only.
Removing dust and grease o n motor housing assures
proper motor cooling.
Fan Bearings
The fan bearings are provided prelubricated. Any specialized lubrication instructions on fan labels supersedes
information provided herein. Bearing grease is a petroleu m
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.
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 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 be arings 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.

Lubricants
Loren Cook Company uses petroleum lubricant in a lithium base. Other types of grease should not be used unless
the bearings and lines have been flushed clean. If another
type of grease is used, it should be a lithium-based grease
conforming to NLGI grade 2 consistency.
A NLGI grade 2 grease is a light viscosity, low-torque,
rust-inhibiting lubricant that is water resistant. Its temperature range is from -30°F to +200°F and capable of intermittent highs of +250°F.
Motor Bearings
Motors are provided with prelubricated bearings. Any
lubrication instructions shown on the motor nameplate
supersede instructions 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 Fan Speed
All belt driven fans with motors up to and including 5 HP
are equipped with variable pitch pulleys.
a. Loosen setscrew on motor pulley.
b. Open or close the groove facing to change the pitch
diameter.
Speed Reduction - Open the pulley in order that the
belt rests deeper in the groove.
Speed Increase - Close the pulley in order that the
belt rests higher in the groove. Ensure RPM lim its
of the fan and the horsepower limits of the motor
are maintained.
c. Retighten pulley setscrew on one of the flat areas of
the motor shaft.
d. After the adjustment is made, check for proper belt
tension. See the Belt and Pulley Installation section.

The correct wheel-to-inlet clearance is critical to proper
fan performance. This clearance should be verified be fore
initial start-up since rough handling during shipment co uld
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 b y loosening the
inlet cone bolts and repositioning the inlet cone.
