Connecting the Wires

Now it’s time to install the wiring. Have an assistant support the weight of the fan while completing the wiring. Here are the steps:

  1. Pass the ceiling fan wires up through the mounting bracket. Include at least 6 to 9 inches of wire above the bracket.
  2. Connect the ground (green or bare copper) wires together with a plastic wire connector. Wrap the connection with electrical tape.
  3. Connect the white (neutral) wires from the ceiling and fan together with a wire connector. Wrap the connection with electrical tape.
  4. Connect the black (hot) wires from the ceiling to the black and blue wires from the fan with a wire connector. Wrap the connection with electrical tape.

Note: The black wire from the ceiling box is usually the “hot” wire while the white is “neutral”. The black and blue wires from the fan are hot.

  2. Tighten the setscrew firmly on the mounting bracket hook to keep the fan securely in place.
  3. Check that the fan is safely seated with no loose connections. Give it a gentle tug to confirm nothing slips.
  4. Slide the fan canopy up to cover the mounting bracket. Insert the canopy screws into the mounting holes and tighten.

Ensure all connections are secure and hidden safely behind the canopy. Check that the fan is firmly anchored and does not wobble.

Finishing Touches

Before restoring power, complete these final installation steps:

  • Attach the fan blades using the provided blade arm screws. Start a screw into each blade, then tighten them gradually to evenly mount the blade. Repeat for each blade.
  • Install light bulbs and glass light covers if your fan includes lights. Take care not to touch the bulbs with your fingers
  • Secure pull chain accessories and remote controls if included.
  • Restore power at the breaker and test that the fan is operating properly on all settings.

Safety First: Make sure everyone stays clear of the blades until you verify correct operation.

That covers the key steps for safely wiring and installing a new ceiling fan. With the right preparation and careful attention to wiring details, you can enjoy cool breezes from your stylish new ceiling fan.
