How to properly install a fan in the bathroom

The bathroom is considered a place of increased dampness. And this can not be avoided even if the walls, floor and ceiling are well finished and insulated. To date, more ways of how to reduce dampness in the bathroom are being developed. One of the most effective ways of normalizing conditions is to install a fan in the bathroom. Here we have in mind not an ordinary fan, but a special, more serious device. It operates from an electrical network on the principle of an exhaust system.

Ventilation installation

The installation of ventilation in the bathroom is the best way to get rid of dampness and moisture.

Installation of a fan in the bathroom is not so difficult. You can do it on your own, if you listen to some useful advice of experienced specialists and masters. Let's consider the whole process in more detail.

First, you need to determine correctly where you place the fan. The best option for this is the place of natural drawing. There will be best air injection, and you do not have to bother with a separate hole in the wall.

The fan should enter the hole as tightly as possible, so immediately make the necessary measurements before buying the design. But it also happens that the ideal size is not obtained. Then you just need to either expand the opening in the wall with a powerful perforator, or, on the contrary, seal the slots during installation with a good mounting foam.

After that you can take up the installation. To do this, it is necessary to remove the front cover, and that part of the housing, which will be adjacent to the wall, should be smeared with special silicate glue. Then tightly press the device and wait for adhesion of the adhesive to the surface.

Pay special attention to sealing the slots in the hole around the appliance after its installation. It is necessary to use a mounting foam even when the device almost perfectly fits into the opening. After all, small slits will still be there. On top of the foam after hardening it is necessary to level the surface with putty and wait for it to dry.

If you plan to install a high power fan, then you will have to focus not on the hood, but on the newly made opening. You will have to tinker with the wall, then install the device there and seal up the gap in the way described above. However, the need to install a powerful fan justifies itself only in large houses, where the bathroom room is also quite large.

Connecting to power

So, when you have entered the device into the wall, you can start the most critical part of the work - to connect it. To do this, you first need to carefully read the instructions and only then start work. The best fans can be installed so that all the wires are not hidden inside the opening. Therefore, you will only need to turn off the electricity and connect the circuit in the wire instructions from the fan with the wiring.

Particular attention should be paid to the safety of further use of the ventilation system. For this purpose, it is better to use special terminals during the connection of the contacts, rather than the usual twists. And the wires should be located just below the ceiling level and covered with a plastic box so that in the event of a breakdown there is no electric shock.

As a rule, most fans work from the network, by plugging the plug into a socket. So the outlet, if it is located directly in the bathroom, should also be reliably protected. To do this, consider installing directly around the outlet of a plastic sealed enclosure that will prevent moisture from entering there. And in order to protect against steam, special removable covers are usually provided, which provide an additional degree of protection.

But fans can be connected to power and in other ways. A common option is to use a regular cord to turn on the device, like a sconce, when moving downward, the device starts working. In this case, the main part of the power connection will be in the exhaust opening. Here it will be necessary to conduct copper wiring and entrust the connection to an experienced electrician.

Another option is the operation of the fan in the bathroom simultaneously with the light sources. Then the light switch in the bathroom adapts additionally to the fan. To do this, a copper wire is drawn directly from the fan, which is connected to the switch by terminals. Naturally, the wire is then protected by a box. Note that in this case it is more expedient to use a powerful switch, adapted to the operation of several devices from it simultaneously.

And one more option is the automatic operation of the fan in the bathroom. This is the most difficult option, because, in addition to the fan, you will also need to purchase a motion sensor. So, when you are in the room, the fan will automatically work. The power connection system here is complicated, so it must be completely trusted by a specialist who is versed in electricity.

So, the basic subtleties of installing a fan in the bathroom are considered.

As you have already seen, installing the equipment yourself is not difficult. The difficulty is only to connect to the food, which can be produced in several different ways. Which method to choose depends on your preferences and capabilities.
