How to connect a fan in the bathroom to the switch with your own hands

The process of installing a fan in the bathroom does not require as much time for installation as for preparatory work. To get down to business, you need to draw up a clear plan of action, decide on the type and model of the ventilation system, study the electrical wiring of the apartment, and also choose the way to turn on the hood.

It is worth noting that the question: how to connect a fan in the bathroom, can be answered by experts in various forums. With any complications - this will simplify installation work.

A hood in the bathroom, as a rule, is not necessary in all cases. If a standard ventilation system completely copes with its tasks, do not waste time installing a more efficient system. However, when basic ventilation is insufficient, serious problems can occur:

  • lack of oxygen;
  • unpleasant odors;
  • condensation on walls, mirrors, etc .;
  • tile destruction;
  • the emergence of pathogenic microbes (mainly mold and microbes).

If any of the above problems occurs, it is recommended to check the standard ventilation for proper operation. To do this, take a match and bring it to the air duct grille. If at this moment the match flame goes out or stretches towards the ventilation side - the system works quite efficiently. Of course, with the opposite behavior of the fire, we can safely conclude that the standard duct does not function.

In some, rather rare cases, it is possible to resume the natural ventilation process. However, to do it yourself, you need to spend a huge amount of time. In addition, during the repair process, the aesthetic appearance of the bathroom can be severely affected.

What is required to install the hood

In order for the installed device to function for a long time and cope with its purpose, it is necessary to create favorable conditions for it.

  1. A properly functioning ventilation duct must be present in the bathroom. In case of clogging and similar problems, after installing the hood, the system will not work. Thus, before installing the fan, you must carefully clean the duct.
  2. When buying a device, you should carefully study its technical specifications. The fan must fully comply with the operating conditions of the bathroom. It is recommended to pay more attention to: cost, functionality, noise level and efficiency indicators.
  3. Since the ventilation system of the bathroom is completely based on replacing moist air with fresh, care should be taken about its source. For these purposes, as a rule, you need to make a 2-cm hole under the door. Thanks to these simple manipulations, fresh air will enter the room through the gap made.

It is worth paying special attention to the fact that installing a fan with your own hands requires a responsible attitude to the installation process. Thus, by the time of installation, all the nuances should be considered. Ideally, it is best to draw up a work plan and be guided by instructions. Also, in case of any complications, it is recommended to refer to special forums on the Internet or to specialists.

Preparing for fan installation

First of all, you need to decide on the model of the fan itself. The selected device must fully comply with the operating conditions.It is recommended to use devices with the following layout:

  • timer, for self-switching on and off the fan if necessary;
  • hydrostat so that the level of humidity in the bathroom is also under control.

Most often, bathrooms use a fan with all the necessary qualities, including moisture resistance, a timer and independence from an uninterruptible power supply.

When installing the hood yourself, you should study the wiring in detail, since it is from it that the device will subsequently be powered. In general, installing a fan requires:

  • gaskets for independent power supply;
  • installation of the device directly into the ventilation duct;
  • sealing joints with mounting foam and putty.

If you correctly draw up an action plan, the entire installation process will not cause any difficulties. However, with problems in understanding and the process of work, it is recommended to seek help from specialists. In an extreme case, there may be a malfunction with the entire power supply of the apartment.

Greater efficiency of the exhaust ventilation system can be achieved if there is an additional source of fresh air (supply ventilation) on one side of the bathroom. The inlet duct and exhaust hood must be located opposite each other, otherwise (with a close proximity) the ventilation of the room will greatly decrease.

Power Operation

The usability of the installed hood is directly affected by both the technical capabilities of the device and the method of switching it on. For each DIY installation method, as a rule, a unique fan connection diagram is required. All required drawings can be easily found online in various forums.

Before finally deciding on the choice of the method of turning on the device, it is necessary to study in detail the positive and negative sides. This way you can simply avoid inconvenience problems.

Through the lighting

The most convenient, in some cases, is the way to turn on the fan while lighting the bathroom. That is, every time a person enters the bathroom, the hood automatically turns on. Thus, when the light is turned off, the ventilation system is also deactivated.

The main problem of this switching method is the inability to use a timer, which is why the device does not have time to clean the air in the room while it is in the bathroom. In addition, if a non-silent fan is used, taking a bath at night will simply not work out due to strong noises and vibrations.

Do not forget that connecting the device to the same line with the lighting can also cause technical problems with an insufficiently responsible approach to work. It follows from this that it is best to turn to specialists, and not do the connection yourself.

Using a cord

Many fan models, initially, have their own switch. Often this switch takes the form of a cord extending from the housing. When manipulating the cord (pulling), the fan turns on or off.

It is worth paying attention to the fact that this method of turning on the device is, most often, inconvenient. This is due to the high location of the ventilation duct (under the ceiling). In addition, sometimes it is necessary to install the hood in hard-to-reach places, which is why direct access to it is very limited.

This method of turning on and off is most convenient in the case of repair work. In addition, you can safely, in addition to the main cord, lay additional wires and install an independent switch for the fan. However, it should be borne in mind that when laying wiring outside of repair work, the aesthetics of the walls of the bathroom can be severely affected.Also, do not forget about the need to connect the main wiring with a hood.

Automatic (independent) inclusion

With this method of turning on the fan, it will be possible to turn it on and off manually. However, in the active state, the device itself will analyze the situation in the bathroom and deactivate if necessary. A timer, a motion sensor, or a hydrostat may be responsible for analyzing a room.

It is worth noting that a fan with an automatic shutdown system is most often equipped to turn on when people are detected in the room and turn off according to the built-in timer. However, be that as it may, such fans are not in great demand in the market due to the high cost.

Self switch

When installing the fan in the bathroom with your own hands, you can conduct separate wiring for the device by connecting it through an independent switch. The option to turn on the device through the cord is completely analogous to this method, but it is more convenient due to the lack of the need for direct access to ventilation.

The most common is the way to turn on via a two-gang switch, that is, at the exit from the bathroom, instead of a conventional light switch, a new two-gang switch is mounted.

This type of switch is not suitable only in case of high humidity in the room.

Wiring

When working with laying, the wire should be based on instructions and safety precautions. Under no circumstances should you work with active electrical wiring - the apartment must be de-energized before the installation process.

When connecting wires to each other, it is recommended to use special brands. Thanks to such connections, the contact between the wires will be much better.

A copper wire must also be connected to the ventilation duct (fan). Ideally, it should be carried out during redecoration, under the tiles. If repairs are not planned, wiring is carried out on top of the wall covering.

Installation work

Usually, in the fan assembly, you can find special instructions for installing the device. In addition, there are all the instructions for further operation and maintenance of the device. All further work must be carried out in full accordance with the requirements.

Installation of the fan takes much less time than preparatory work. Thus, installing a fan in the bathroom will take about 15 minutes.

  1. It is necessary to remove the front side of the fan.
  2. At the junction of the device with the walls, glue or silicone must be applied.
  3. The fan must be carefully placed in the duct and pressed firmly for several minutes (drying time of the connecting substance).
  4. It is necessary to fix the device cover using self-tapping screws. Most often, all the necessary components are supplied with the device.

In addition to the basic installation work, it is recommended to install a mosquito net on top of the device.

The entire installation process can be considered complete. After installing the device, but before closing the lid, as a rule, it is necessary to connect the fan to the previously laid wire.

In case of any non-compliance with safety standards, serious problems are possible, fraught with both unstable power supply of the entire apartment, due to short circuits, and the inoperability of the installed fan.

It is worth noting that the question of how to connect a fan in the toilet and bathroom can be considered exhausted. Incomprehensible nuances can be found on forums on the Internet or read the instructions that came with the fan.
