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.

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 affects 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.

These compact inline fans are the ideal selection for indoor clean air applications including intake, exhaust, return, or make-up air systems. The square housing design, compact size, and straight-thru airflow also provide the system designer the flexibility to mount in horizontal and vertical orientations. Each fan displays a permanently stamped metal nameplate with complete model number, mark, and unique serial number for future identification. 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.
