Overhead fans are installed on a suspended ceiling consisting of plastic panels, as well as on the rack ceiling to the ventilation hole in the wall with the installation of the corrugated pipe. And the easiest way to connect a cooling fan is to install it in the ventilation duct. After that, it is necessary to remove the wires from the ventilation pipe, which are used to supply power to the fan itself. Route the wiring in the wall and connect it to the switch.

According to the established rules, the air in the bathroom and toilet must have a tenfold exchange in 1 hour.

If you do not want your fan to work as long as the light in the bathroom or toilet is lit, you can power the fan separately. To do this, take a wire the length of the distance from the switch to the junction box and from the ventilation shaft to the switch. Then find the phase in the box, zero and power the wire. Usually, simple fans are not sensitive to polarity, but this depends on the motor model installed in it. Be sure to pay attention to it, otherwise you can get not a hood, but a fan that sucks in air. At the end of the finishing works in the bathroom or in the toilet, you can start the installation itself, as well as connect the fan. Lead the wire through the special holes, then insert the fan into the shaft hole and secure. To attach the fan to the plastic, use self-tapping screws, and for silk tiles, silicone sealant is perfect. Finally, connect the wire and replace the fan guard.
