Open Plenum Array

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.

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.

Only qualified personnel should install this array. 
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. 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 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 the wheel faster than max cataloged 

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.
