If the sleeve is needed, insert the sleeve into the
garnish ring positioning the notch in the sleeve to line
up with the wiring.
•
Raise the garnish ring to the ceiling/wall ensuring
that the garnish ring is centered over the fan
opening.
•
If using the sleeve, the sleeve will overlap the base
that extends in the opening. This will help center the
garnish ring in the opening.
•
Ensure that the wires are not pinched. The wires
should be routed on the outside of the sleeve. The
