Replacing an existing light fixture with a ceiling fan is only slightly more cumbersome than installing a light fixture.
Ceiling stand 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.
Determine how far down your fan will hang once mounted. Measure from the floor to the ceiling and subtract the fan measurements. 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.
Install the hook or hanging support and hang the housing unit. If the box fan requires a hanger pipe, thread wires through the pipe. Attach the pipe to the box and fan per manufacturer’s instructions.
Follow the manufacturer’s instructions to attach the blades and install decorative pieces of evaporative air coolers. 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.
