To install a ceiling fan lamp, the first step is to deactivate the circuit by removing the corresponding fuse or tripping the circuit breaker. Alternatively, you can turn off the main switch to cut off the power to your home.

Next, remove the original light fixture from the ceiling by unscrewing or unbolting it. Once removed, lower the lamp and disconnect the wires, being sure to mark each wire with masking tape for later identification.

Consult the manufacturer's color coding instructions for wiring and recommended steps for ceiling fan installation. Typically, there are two wires in the circuit and three wires in the lamp. Connect the black wire to the black wire, the white wire to the white wire, and connect the remaining ground wire (which may be bare or green) to the metal junction box or to other locations suggested by the manufacturer. Use wiring nuts to secure the connections and check for tightness after connecting.

Check the wiring again, referring to the manufacturer's instructions, and carefully push all the wires into the junction box (which may be a metal or plastic box for electrical connections). Connect the ceiling fan to the junction box or hook according to the manufacturer's instructions.

If you are installing a light under the fan, make sure the two parts belong to the same brand and are designed to work together for easier installation. Remove the bottom cover from the fan unit, then pull out the ends of all loose wires, and connect them according to the manufacturer's instructions. This usually involves connecting the black wire to the black wire, the white wire to the white wire, and the ground wire to the ground wire.

Finally, re-energize the circuit and test the system. While many home appliance repairs can be done by yourself, it is important to take appropriate safety precautions and contact a professional if necessary.
