ATTENTION: Upon completion of the mechanical installation of the fan and before powering on, spin
the fan around multiple times by hand to ensure all brackets are clear from contact with other parts on
the fan. Thoroughly inspect the hub, the bolts and brackets within the hub to guarantee clear and proper
rotation. If you find that the fan has a bracket that is hitting another object on the hub, contact Canarm
for a resolution.
