Always disconnect, lock and tag power source before 
installing or servicing. Failure to disconnect  power 
source can result in fire, shock or serious injury.

When servicing the fan, motor may be hot enough 
to cause pain or injury. Allow motor to cool before

atmospheres.

Only qualified personnel should install this fan. 
Personnel should have a clear understanding of 
these instructions and should be aware of general 
safety precautions. Improper installation can result 
in electric shock, possible injury due to coming in 
contact with moving parts, as well as other potential 
hazards. Other considerations may be required if 
seismic activity is present. If more information is 
needed, contact a licensed professional engineer 
before moving forward.

  1.  Follow all local electrical and safety codes, as 

well as the National Electrical Code (NEC) and 
the National Fire Protection Agency (NFPA), 
where applicable. Follow the Canadian Electric 
Code (CEC) in Canada.

  2.  The rotation of the wheel is critical. It must be 

free to rotate without striking or rubbing any 
stationary objects.

  3.  Motor must be securely and adequately 

grounded.

  4.  Do not spin fan wheel faster than max cataloged

amps.

in contact with oil, grease, hot surfaces 
or chemicals. Replace cord immediately if
