GENERAL INFORMATION
RECEIVING & INSPECTION
When receiving fans, a thorough inspection of the fan must be made to assure no damage was incurred
during shipment. Check fan completely for any dents or scratches. If any damage is found, report damage
to carrier and notify factory immediately. Failure to report any shipping damage may result in additional
costs to the customer. If possible, take pictures (preferably digital) of the damage. If there is minor
damage and can be repaired at sight, contact factory for replacement parts or touch-up paint.Any damage
to working parts of fan (wheel, shaft, motor,) may require a return to the factory. Call factory for a return
goods authorization.
IDENTIFICATION INFORMATION
Every fan manufactured by Car-Mon products is thoroughly tested before it leaves the factory, and is
assigned a manufacturing number.

HANDLING
Fans should be hoisted with slings placed around the fan housing. When a single hoist is used, a "spreader" will
keep the sling from slipping on the housing. If it is necessary to use hooks placed in lifting holes of fans, BE
CAREFUL NOT TO DISTORT OR BEND THE HOUSING. Large units may have lifting lugs or holes which should
be used in place of the sling.
Chain or wire slings should be well padded where they contact the fan, especially where special coatings and
paints are involved. Rubber, phenolic enamels, etc. require special care as they may easily be damaged by
contact in lifting. Even a small chip will destroy the corrosion prevention seal of the coating and allow corrosion to
start. Always repair scratched surfaces with touch-up like coating prior to installation.
STORAGE
If the fan is to be stored for any length of time, appropriate care should be taken to protect bearings, shaft and
finished surfaces from moisture, dirt, dust, etc. Do not store other products on top of fan equipment. Periodic
inspections of the unit should be made until it is ready to be put into service. If fans are stored for a considerable
period that may pass the time of the warranty agreement, the warranty will not apply.
FOUNDATIONS-GENERAL
A rigid level foundation is a must for every fan. It assures permanent alignment of fan and driving equipment and
freedom from excess vibration, minimizing maintenance costs. Foundation must be cast separate from any
adjacent floor structure and separated around edges by at least 3/4" tar felt to prevent transmission of vibration in
either direction. The sub-foundation (soil, stone, rock, etc.) should be stable enough to prevent uneven settling of
fan foundation. Car-Mon is not responsible for foundation design. The natural frequencies of the foundation must
be sufficiently removed from the rotational frequency of the fan to avoid resonant conditions.
EQUIPMENT MOUNTED FANS
If the fan is mounted on equipment having parts which cause vibration, it is very important that the fan support is
rigid enough to prevent such vibration being carried to the fan. The resonant frequency of the support should
avoid the fan running speed by at least 20%. It may be advisable to use vibration isolators under the fan.
STRUCTURAL STEEL FOUNDATION
When a structural steel foundation is necessary, it should be sufficiently rigid to assure permanent alignment. It
must be designed to carry, with minimum deflection, the weight of the equipment plus the loads imposed by the
centrifugal forces set up by the rotating elements. We recommend welded, riveted, or suitably locked structural
bolted construction to best resist vibration. In certain applications, it is recommended that vibration isolators,
selected specifically for weight and span conditions, be installed.
Fans installed above ground level should be located near to, or above a rigid wall or heavy column. An overhead
platform or support must be rigidly constructed, level and sturdily braced in all directions.
POURED CONCRETE FOUNDATIONS RECOMMENDED
Poured concrete under the fan and all drive components is the best fan foundation. a generally accepted rule of
thumb is that the weight of the concrete foundation be a least three (3) times the total weight of the equipment it
will support. This weight acts as an inertia block to stabilize the foundation. Where the ground is soft the
foundations should be flared or the footing course increased in size to resist settling. the top should extend at
least size (6) inches outside the outline of the fan base and should be beveled on the edges to prevent chipping.
VIBRATION ISOLATION
Car-Mon recommends the use of vibration isolation. Rubber in shear (RIS) can be used with the fan mounted on
grade with fan wheel diameters up to but not including 27 inches. At 27" and larger only spring isolation should be
used. Other construction is available. On occasion it may be advisable to use an isolation base to better distribute
the load to be isolated.

WIRING
Make sure that the fan is wired properly and the motor is running in the proper direction. Damage caused to
motors by improper wiring will not be covered in the warranty. Wiring diagrams for most of the motors supplied on
our fans are located on page in this manual. There should also be a wiring diagram on each motor plate. If you do
not have the proper diagram, please contact the factory with the motor brand and model number and we will send
a copy of the diagram to you.
PRE-OPERATION INSPECTION
With the fan mounted in operating position:
1. Lock out electrical power to prevent accidental fan operation.
2. Recheck tightness of foundation bolts, wheel setscrews, motor mounting bolts, bearing bolts and setscrews,
coupling setscrews, access door bolts, etc. Tighten to proper torque values if necessary. NOTE: Fan hub
setscrews should be tightened when vertically below the shaft.
3. Rotate wheel manually to make sure it runs freely without binding or striking the inlet or housing. If the wheel
strikes the housing, the wheel may have to be moved on the shaft.
4. Check bearing alignment and make certain they are properly locked to the shaft and lubricated if applicable.
5. If fan is belt driven, check sheave alignment. Improper sheave alignment is one of the most frequent causes
of excessive fan vibration. Check belt tension. Belt tension is the usual cause of shortened belt bearing life.
6. If equipped with inlet vanes and/or dampers, check for correct linkage operation. Make sure that the operator
opens and closes these control devices to the proper position.
7. If this product was furnished with a motor mounted by the factory, refer to and observe the motor
manufacturer's instructions attached to the fan before removing the electrical lockout of the power source.
START UP
Check the correct direction of rotation by "hitting" the ON button and then the OFF button. Correct the rotation if
necessary and the unit can be put into service. Keep a close watch for any unusual vibration, noise, etc.
If you observe any unusual vibration or noise, stop and lockout the unit and recheck all items in the preoperation
inspection check list above before requesting assistance from our factor representative.
After 24 hours of satisfactory operation, shut down the equipment and check all foundation bolts and setscrews
for looseness, tightening where required.
SOME CAUSES OF VIBRATION
1. Bearings: Misaligned or worned loose bolts or setscrews.
2. Motor: Misaligned or unbalanced, worn bearings, loose bolts or setscrews.
3. Bent shaft: Equipment dropped during shipment or installation.
4. Coupling: Misaligned
5. Loose foundation mounting bolts.
6. Wheel: Loose setscrews, material accumulation or wear and erosion causing imbalance.
7. Fan inlet or outlet volume control devices completely closed off.
8. External source of transmitted vibration.

1. Bearings are pre-lubricated at the factory. For grease recommendations see bearing manufacturer or consult
factory.
2. Bolt and setscrew tightness. Check bolts and setscrews to assure they are still tight.
3. V belt drive, worn belts or sheaves, proper tension. Check periodically to see if these parts are showing
excessive wear. If it is necessary to replace one belt on a multiple belt drive unit, replace all the belts with a
matched set.
4. Wheel wear or material build up on wheel causing unbalance will quickly damage bearings or cause self
destruction of the fan wheel. Check for any build up of foreign material.
MODIFYING FAN PERFORMANCE-BELT DRIVE FANS
If you want to raise or lower a belt drive fan's performance by opening or closing the adjustable sheave, it is highly
recommended that before making these adjustments you consult the factory or the Car-Mon Fan Catalog to
assure the motor horsepower is adequate for the new performance. If you need an additional sheave or another
motor, please contact your local Car-Mon representative. Please note that changing performance, drives, or
motors may void the original factory warranty.
MAINTENANCE & ADJUSTMENTS
A planned program of regularly scheduled maintenance will return dividends in averting a possible costly and
unexpected period of down time. Following are some of the more imprint considerations:
SAFETY PRECAUTIONS
Any piece of machinery should be treated with respect and not over confidence. Over confidence usually leads to
carelessness and carelessness leads to injury. Following is a list of safety DO'S and DON'TS.
DO
1. On a belt drive unit, fan should be equipped with either a belt guard or a weather hood.
2. If there is no inlet duct work, fan should be equipped with an inlet screen.
3. If there is no outlet duct work, fan should be equipped with an outlet screen.
4. Make sure fan is stopped and electrical power locked out before putting hands into fan inlet or outlet opening
or near belt drive. We suggest a warning sign on START SWITCH cautioning not to start when fan is being
serviced and a padlock on the disconnect.
DO NOT
1. Put hands near or allow loose and hanging clothing to be near belts, sheaves, couplings or cooling wheels
while fan is running.
2. Put hands into inlet or outlet while fan is running.
It is sometimes difficult to tell whether or not a fan is running. BE SURE it is not running and cannot be operated
before any inspection.
ADDITIONAL SAFETY PRACTICES
For additional safety practices on installation and operation, please consult AMCA Publication 410-96 "Safety
Practices For Users and Installers of Industrial and Commercial Fans" A copy of this should be enclosed in the
packet with these instructions. If copy was missing or you require extras, please contact Car-Mon Customer
Services.
The adjustable sheave is mounted on the motor. The fan's performance
can be increased or decreased by opening or closing the sheave.
Before making adjustments, please call the factory. Improper adjustment
may seriously damage the motor and void the warranty of the fan.

belts may last for years,
however they should be
checked annually for wear.
Disconnect power from fan,
remove belt cover, and
check both belts carefully.
To change the fan belts,
loosen the bolts on both
sides of the motor base,
raise base up several inches
until belts are clear of drives.
