First of all, according to the situation and needs of the bathroom, there are generally two kinds ofexhaust fans - top suction type and window straight type.
1) Top suction type: This exhaust fan is installed on the ceiling, which is more beautiful, but it needs to have an exhaust hole with a diameter of 9cm (it needs to be professionally made in the wall), and there needs to be a certain space above the ceiling.
2) Window in-line type: It can be installed directly on the window, but the stability of the mounting bracket and the cutting of the glass should be considered.
In the case of the installation of a top-suction exhaust fan, the following steps are required:
1) Lay the exhaust hole in advance, generally find a professional master to do it, and the price ranges from 30-80 yuan.
2) There is a switch terminal in advance, generally on the multiple sets of switches next to the bathroom door, and one group is to control the ventilation fan. If it is a separate exhaust wiring, it is relatively simple, and the reserved two wires can be directly connected to the two wires of the exhaust fan; If it is heating, shifting, and synthesizing, it is recommended to directly use the control switch provided by the original manufacturer, and properly connect the wire of the original switch with the reserved wire. If there is no reserved dark line, you can only take the bright line in the form of a wire slot.
3) The position installation is relatively simple, remove the ceiling piece, and replace the original position. The current top suction type is generally 30*30 cm, which just occupies the area of a ceiling piece.
In the case of the installation of an in-line exhaust fan, the following steps need to be processed:
1) Measure the installation size in advance and plan the installation location when purchasing. If aluminum windows, you can consider installing them directly on them, in the form of drilled holes and self-tapping screws. For even more firmness, you can also add an aluminum strip yourself.
2) Reserve the dark line, if there is no reservation, you can use the form of a trunking to arrange the open line on the wall, or use the way to connect with the lighting (exhaust as soon as the light is turned on).
3) The wiring is generally only two wires, the live wire and the neutral wire, and the strong and weak gears are controlled by the mechanical wiring switch. It should be noted that the wiring should be insulated with adhesive tape and waterproof.
