CAUTION: The oil plug on the fan models listed above must be replaced with the oil vent cap to optimize performance. The
proper oil vent cap is packaged in a bag attached to the motor unit.
If your fan model does not require an oil vent cap, proceed to "Installing Airfoils" (p. 26).
1. Replace Oil Plug

gear reducer may spill out.

Remove the oil plug, and then install the oil vent cap as shown. Screw the cap into place by hand, being careful not to strip the threads.
