5.1 System Testing
• Check the voltage with the motor nameplate rating.
• Check that the transport securing device holding the motor shaft and impeller in place has been
removed.
• Determine if the impeller is free and has not been subject to misalignment in shipping or installation.
• Apply power and check that the impeller is rotating in the direction of the arrow on the side of the top motor
cover. All ENERVEX fans run in a clockwise direction when viewed from the top. Double check
if three phase motor is tested on temporary wiring. Switching any two leads will reverse the rotation.
