Make sure the electricity is turned off.
Safety alert: Always turn off the breaker before working with any electricity. Make sure you attach a bold note to the breaker box that says, "Do not touch. I'm working with the electricity."
Read through the manufacturer's instructions and assemble all the tools you'll need.
Put up a support brace between the ceiling joists where you want the fan, because fans can weigh up to 50 pounds. If your ceiling is covered with drywall, you'll need to access the joists through the attic to attach the support brace. If you're attaching the fan where a light has already been, that's all you need to do. But if it's a new area, you'll then need to cut a piece of drywall the size of your electrical box from the ceiling, so that you attach an electrical box to house the fan.
Identify the wiring that is coming out of the electrical box. In this case, I'm working with a bare copper ground wire, the black "hot" wire and the white neutral wire. They will supply electricity to the fan. There's also a green ground wire that goes to the fan itself.
Put the fan motor in by slipping the swivel ball into the bracket.
Match the wires from the electrical box to the wires from the ceiling fan, following the manufacturer's instructions and twisting them. Fasten the ends together with wire nuts (Image 1).
Working smarter: Bring extra wire nuts when you go up on the ladder, so you won't have to come back down to get more if you drop one.
Stuff the wires back into the electrical box, and attach the cover (Image 2). Slip the cover's keyhole slots over the screws to keep the cover in place. Then finish attaching the screws, and slip the trim ring over the screws to cover them up.
Attach each of the fan blades to its bracket.
Working smarter: Save time by assembling the fan blades before you install the fan.
Use screws and a screwdriver to attach the fan blade brackets into the appropriate notches on the fan motor (Image 1).
Attach the light by clicking the light connector to the corresponding fan connector and then screwing the fixture to the fan (Image 2). Last, snap the dome over the light, screwing it in place if necessary.
