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.
