Carefully lift the assembled fan motor and downrod. Hook the ball on the end of the downrod into the mounting bracket installed on the ceiling. There will be a slotted area in the bracket to securely hold the ball. Make sure it's properly seated. Now, proceed with the electrical connections. Connect the wires from the fan to the corresponding household wires using wire nuts and electrical tape. Typically, a red wire from the ceiling connects to the black fan motor wire, a blue wire from the fan motor connects to the black light wire (from the downrod), all white (neutral) wires connect together, and all green/bare copper (ground) wires connect together. Always consult your specific fan's instruction manual for precise wiring diagrams. Once connections are made, carefully tuck them into the electrical box.
