Arrangement of forced ventilation in the bathroom provides installation of the hood. The cooler must be connected according to a pre-prepared scheme. A drawing is made on millimeter paper. Connection and installation work is carried out using the fan instruction.
The installation of ventilation in the bathroom is the best way to get rid of dampness and moisture.
To ensure that the bath was free of condensation and microbes, they arrange forced ventilation. Experts recommend regularly checking the ventilation duct for serviceability. To do this, a fired match is brought to the grate of the air exchanger. Additional ventilation is not settled if the flame is drawn to the grate and does not go out. Otherwise, the bathroom will need to install and connect an exhaust fan.
The device is chosen taking into account its technical characteristics. Experts recommend buying a device with a hydrostatic. A similar unit controls the humidity of the air. If the humidity level is above normal, then the fan automatically turns on.
Scheme of fan connection.
Increase the effectiveness of the ventilation system can be, having arranged on one side of the bathroom the input of air masses, and on the other - the air outlet. To ensure a constant influx of fresh air masses, a grid is mounted at the bottom of the door.
A switch is provided in the body of the unit. The device can be switched on simultaneously with lighting. Experts do not recommend connecting the hood and fan to one switch. Otherwise, the device without the "timer" function will not be able to update the air until the light is turned off in the bathroom. Specialists recommend to install a two-key switch: one key is used to illuminate the room, and the second - to turn on the device.
If necessary, the device can be turned on / off by itself, pulling the string or pressing the button.
To equip the automatic shutdown of the unit, install a humidity or motion sensor.
The device turns off after the time set on the timer. The bathroom is de-energized beforehand. Terminal blocks provide reliable contact. Copper cable is masked in a box.
The exhaust fan is recommended to be installed near the outlet. The ventilation standard channel ensures the passage of air masses pumped by a fan with a capacity of 100 cubic meters per hour. The device is selected taking into account the diameter of the channel.
If the diameter of the channel is less than that characteristic of the fan, then the hole is expanded with a perforator. Otherwise, use a plastic pipe or corrugation (taking into account the diameter of the hood). Emptiness is sealed with foam. Surplus material is cut with a knife. Putty is used when the diameter of the hole is larger than the lattice size.
The front cover of the device is dismantled. On the installation site, silicone or polymer glue is applied to the wall. A similar fixing method is used for a plastic device. The fan is mounted in the corresponding hole. The front cover is fixed to the self-tapping screws. Fasteners are included in the kit. The mosquito net prevents the penetration of various insects into the house. It is recommended to install it before installing the lid. To muffle the noise that appears when the device is operating, sound absorbing material is used. It is allowed to install a sound attenuator (behind the main unit). Such work is recommended to be done with the help of professionals.
