Once the electrical connections are complete and secure, gently lift the fan motor off the hanger hook. Now, attach the canopy (sometimes called a shroud) to the mounting bracket. This canopy covers the electrical wiring and provides a finished look. As you secure the fan in its final position, make sure that the slot in the nylon ball (located on the downrod of the fan) is perfectly in line with the guide pin on the mounting bracket. This ensures the fan hangs correctly and prevents wobbling.
