Installation, Operation and Maintenance Manual

Please read and save these instructions for future reference. Read carefully before attempting to assemble, install, 
operate or maintain the product described. Protect yourself and others by observing all safety information. Failure 
to comply with these instructions will result in voiding of the product warranty and may result in personal injury 
and/or property damage.

General Safety Information

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. 

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 fan 

RPM. Adjustments to fan speed significantly effects 
motor load. If the fan RPM is changed, the motor 
current should be checked to make sure it is not 
exceeding the motor nameplate amps.

5.  Do not allow the power cable to kink or come in 

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

6.  Verify that the power source is compatible with the 

equipment.

7.  Never open access doors to a duct while the fan is 

running.
