My bulb for my fan has gone out, but I'm having difficulty removing the glass dome to get to the bulb.

Any instructions?

If possible, does anyone know how to get an instructional manual for it? I've seem to have lost it.

Harbor Breeze 52" Armitage White Ceiling Fan
Item #: 20776 | Model #: CC52WW5C

If it is a half dome and you can't see any set screws, try holding the fan steady and twist the dome counterclockwise, it is snugged into 3 detents and should drop out. You may have to pry slightly but be careful you don't break the dome. Good luck.
