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 instructions could result in personal injury 
and/or property damage!

®

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 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) 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 

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.

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 servicing.

Precaution should be taken in explosive atmospheres.

Greenheck’s Series L, low silhouette, models LD, LB, 
LDP, and LBP centrifugal roof exhaust fans provide the 
industry’s best performance and durability for general clean 
air applications. Series L exhaust fans have the broadest 
performance in the industry, up to 1.25 in. wg (311 Pa) and 
37,500 cfm (63,713 m

/hr).

The severe duty models LDP and LBP are far superior to 
any centrifugal roof exhaust fan currently in the market. 
Specifically designed for applications with extremely high 
structural design load requirements. Designed with structural 
steel supports and ESD-603D louver blades, the severe duty louver enclosure (SDLE) may be used in any 
application which requires a fan to endure high winds with the potential of wind blown debris. Miami-Dade
