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.

Only qualified personnel should install this system. 
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 high winds 
or seismic activity are 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), the National Fire 
Protection Agency (NFPA), where applicable. Follow 
the Canadian Electrical Code (CEC) in Canada.

2.  All moving parts must be free to rotate without 

striking or rubbing any stationary objects.

3.  Unit must be securely and adequately grounded.
4.  Do not spin fan wheel faster than maximum 

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 the unit while it 

is running.
