Tips for installing a ceiling fan
By Caryn Colgan, Networx
Replacing an existing light fixture with a ceiling fan is only slightly more cumbersome than installing a light fixture. While it is best to leave electrical projects to licensed electricians, do-it-yourselfers with electrical experience often install ceiling fans themselves. The tricky parts involve purchasing the right sized fan and lifting the sometimes heavy motor unit in place. If you have installed light fixtures, you can install a ceiling fan.
Ceiling fans are an unobtrusive and economical way to cool a room in summer and move heat back down to floor level in winter. For best air flow, locate a ceiling fan in the midpoint of the ceiling. If the existing light fixture is off center but close to center, it is easier to use its wiring than to install a new box and wiring.
How Low Can You Go?
Determine how far down your fan will hang once mounted. Measure from the floor to the ceiling and subtract the fan measurements. For safety reasons, the result should be at least 7'. The fan blades should also be at least 12" below the ceiling with an optimum distance of 18".
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.
Assemble the Ceiling Fan
Follow the manufacturer's instructions to attach the blades and install decorative pieces.
How to Mount the Ceiling Fan
Install the hanger bracket to the box with screws and lock washers. Use lock washers to prevent the fan's vibration from loosening the screws. Connect the wires by matching black to black and white to white by twisting to the right with wire nuts. Wrap with electrical tape. Next, ground the fan to the box. A grounding wire is either green or a bare copper wire. Using a wire nut and twisting right, connect the ground wires from the box and the fan together. Wrap each wire nut with electrical tape and gently push wiring inside the box. Finish by installing any other decorative pieces.
Ceiling fans are an economical way to reduce heating and cooling costs. While hiring a professional electrical contractor is the best way to ensure your fixture is installed according to building codes, it is also the most expensive option. Careful do-it-yourself weekend warriors can install a ceiling fan and enjoy year round comfort.
