The first thing you should do is remove the ventilation grille from your bathroom. Then you will need to carefully read the instructions so you can route the wires from the bulb to the exhaust fan. Then you plug them into the power source of the bulb. Place the extractor on the ceiling and, with a saw, adjust the ceiling gap with its measurements. Then turn on the power. Verify that it works perfectly once you press the light switch. You can test it several times to verify its normal operation. In addition to all its advantages, this device will also save you a lot of energy.
