Preparation for the Ceiling Fan
Begin by turning off the power at the panel or by unscrewing the fuse in older systems. Never trust the switch. Remove the existing light fixture. Since each fan may be different, refer to the installation guide included in the fan kit.
Consider using a fan support unit that can be inserted through the existing metal junction box hole. Do not install a ceiling fan to a plastic box since it will not be strong enough. Always use a metal junction box to support a ceiling fan. If your fan is heavier than 35 pounds, you will need to secure your fan via a beam or other support, not a junction box.
Install the hook or hanging support and hang the housing unit. If the fan requires a hanger pipe, thread wires through the pipe. Attach the pipe to the box and fan per manufacturer's instructions.
