Roof Supply Fan

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.

Centrifugal Supply Fans

Fans are specifically designed for filtered roof supply 
applications. Fans feature permanent washable 
aluminum filters for years of reliable use and double-
width forward-curved wheels for high efficiency and 
low sound. Available with straight-sided hood or 
architectural louvered penthouse housing.

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 affect 
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.

DANGER

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

CAUTION

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

CAUTION

Precaution should be taken in explosive atmospheres.

DANGER

Pour écarter les risques d’incendie, de choc électrique 
ou de blessure grave, veiller à toujours débrancher, 
verrouiller et étiqueter la source de courant avant 
l’installation ou l’entretien.

ATTENTION

Lors de toute intervention sur la soufflante, le moteur 
peut être suffisamment chaud pour provoquer une 
douleur voire une blessure. Laisser le moteur refroidir 
avant toute maintenance.

ATTENTION

Faire preuve de précaution dans les atmosphères 
explosives.
