How to connect the fan?
A fan can be installed to eliminate odors and reduce humidity in the toilet or bathroom. Due to the different type of fans, it can be installed both during repair and after it.
Possible fan options
There are overhead and duct fans. They all differ in the method of installation. There are several ways to connect fans. You can bring the fan to a separate switch or connect it directly to the main lighting of the bathroom or toilet. In the second case, it will work only when the light is turned on. In addition, modern models of fans have humidity sensors. They continue their work until moist and damp air comes out of the room (only with a separate switch). Before you buy a fan, you need to choose the most convenient way how to connect a fan and, based on this, make your choice. Thus, duct fans and fans with a sensor are almost never used in apartments, since they often break.In addition, for such fans it is recommended to install a separate switch, which adds additional complexity during the installation process. Although this switch is much more convenient. Also, before buying you need to choose a place where to connect the fan. Overhead fans are installed on a suspended ceiling, consisting of plastic panels, and also on a rack ceiling to a ventilation hole in the wall with installation of a corrugated pipe. And the easiest way to connect a cooling fan is to install it in the ventilation duct. Then 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.
Calculation of fan power
It is not necessary to buy a large fan, since a small fan also has the necessary performance. According to the established rules, the air in the bathroom and toilet should have a tenfold exchange in 1 hour. To calculate the performance of the fan for one hour, multiply the volume of the bathroom or toilet by 10.To make it easier to cope with the work of connecting the fan, read the step-by-step guide on how to connect the fan in the bathroom or toilet: So, when choosing a fan, mainly pay attention to its power, performance and size. All these data are listed on the packaging.
It is advisable to prepare for the installation of the fan at the very beginning of repair work. The preparatory work consists of wiring the electrical wire to the place where the fan will be located (ventilation shaft).
It is also very convenient to connect in parallel the fan to the lighting device. To do this, turn off the power to the mains, then take the wire of the required length and connect it to the wire that supplies electricity to the bathroom or toilet. It should be noted that both wires must be made of the same material and have the same cross section. If you do not want your fan to work as long as the lights in the bathroom or the toilet are lit, you can power the fan separately. To do this, you will need to take a wire with a length equal to the distance from the switch to the junction box and from the ventilation shaft to the switch.After that, find the phase in the box, zero and power the wire. Usually, simple fans are not sensitive to polarity, but this depends on the engine model installed in it. Be sure to pay attention to this, otherwise you can get not a hood, and the air sucked inside the fan. At the end of the finishing work in the bathroom or in the toilet, you can begin the installation itself, as well as the connection of the fan. Pull the wire through the special holes, then insert the fan into the hole of the shaft and fasten it. To attach the fan to the plastic, use self-tapping screws, and silicone tile is perfect for tile. Finally, attach the wire and reinstall the fan guard.
