Installation of the fan in the bathroom and toilet .

In this article we will talk about mechanical ventilation in the toilet and bathroom. Forced ventilation is when inserted in the vent fan. In this article we consider the basic models of fans that are frequently used and their connection schemes.
Do I need a forced ventilation?

Forced ventilation is necessary to do then when conventional ventilation is not effective or too weak. The first signs that the ventilation is not doing its job is fogged mirror, condensation on the walls, odors and mold.

If you encounter this problem, first of all you need to check on the serviceability of the vent. He checked very easy for this to the vent need to bring a burnt match. If the memory delays in the ventilation means to vent all right, he just can not cope with this area of the room. And in such cases need to install a forced ventilation. And if the flame does not even match fluctuates, it is necessary to clean the air ducts. To do this, on the roof to vent the weight is lowered tapered.
The fan in the bathroom.

I recommend to install the fan in the bathroom so that you have gone to the bathroom, turned on the light and automatically turn on the fan. Came out of the closet, turned off the light and thus turns off the fan. There are three-pin fan with timer and humidity, which after the light is turned off for some time work, self timer and moisture sensor, you can adjust himself. They are called fans with timer. In my opinion, a fan with a timer in the bathroom, as well as the bathroom is more effective than usual. And should he not much more expensive than usual.

This diagram shows the wiring diagram of the classical fan. Which turns on the fan with the light on and off together also. The scheme is simple enough. It should be connected in parallel with the fan lighting. Zero of the junction box is right on the lights and fan, and phase through the switch.

This diagram shows the connection with a single speed fan timer. This scheme is a little more difficult the previous one. From the junction box directly to the fan is the phase and zero, and zero to the bulb only. And through the switch to the bulb and the fan is phase. Only phase that goes through the switch to the fan must be connected to the terminal which is marked on the fan as LT or T. A time that the fan should run after switching off the light is regulated directly on the fan. You can also directly connect the fan with three contacts - to connect the neutral N (zero) and L & T connects plus.

The fan in the bathroom

Fan in the tub may be connected by methods such as described above, and still others may be. On the other methods of connecting the fan, we now discuss.
If ventilation in the bathroom more - less than normal, and the need to include mechanical ventilation only need while taking a shower or bath, then I recommend you the following connection diagrams forced ventilation.
One of which is a fan with an external switch. He serves as the shifter in some models of fans. The principle of operation of the fan is that it does not operate continuously. You turn it on when it's really needed. Typically, the switch is a cord that is outside. Pulling it, you can turn off the fan speed or switch. This fan is very practical because the bathroom is not necessary to constantly switched on the fan.
Quite similar to the previous method of connection is the following method. You turn off the fan is not directly on the fan, pulling the rope, and the entrance to the bathroom. To do this, put on input series switch, wherein the first key is responsible for the lighting in the bathroom, and the second for the fan.

Next, we consider the fan wiring diagrams of these two methods.

The scheme is simple enough. Here directly from the junction box is the phase and zero to the fan.

Wiring diagram for the fan to switch.

Zero directly from the junction box is on a ventilator. A phase to the fan goes through the switch.

Attaching the fan.

When will we hooked our fan remains the case for small, install a fan. Usually in such vents we need to install the fan.

On the back side of the fan smear glue. It may be silicone, liquid nails, and the like.

Pressed against the wall and hold for about one minute, then let go.
