Hood in the bathroom: selection rules and installation features

Ensuring adequate ventilation is crucial for designing a cozy and practical home atmosphere. The restroom is one place where this is very important. A bathroom hood, sometimes referred to as an extractor fan or exhaust fan, is essential for eliminating allergens, excess moisture, and odors from the air and preserving a hygienic and comfortable interior environment. This post will go over the significance of choosing the appropriate bathroom hood as well as important installation factors.

Selecting the ideal bathroom hood requires more thought than simply picking the first one you come across. A number of variables come into play, including the size of your bathroom, the amount of moisture created during baths or showers, and the desired degree of noise reduction. You should also take into account the hood’s overall performance and energy efficiency to make sure it effectively removes moisture and odors while using the least amount of energy.

Another crucial element in guaranteeing the efficiency of your bathroom hood is installation. In addition to guaranteeing peak performance, proper installation lowers the possibility of structural damage to your house. It’s crucial to evaluate your bathroom’s layout and choose the hood’s ideal placement to optimize ventilation and airflow before installing a bathroom hood.

A crucial factor to take into account while installing is the ducting. In order to effectively remove moist air from the bathroom and outside, proper ductwork is necessary to stop the growth of mold and mildew. In order to minimize bends and obstructions that can impede airflow and lower the effectiveness of the hood, the ductwork should be installed and sized appropriately.

And lastly, to guarantee that your bathroom hood remains effective over time, routine maintenance is essential. This entails routinely cleaning the ductwork and hood to get rid of any accumulated dirt, dust, or debris that can impede airflow. Additionally, you can prolong the life of your bathroom hood and make sure it keeps working properly for years to come by looking for any signs of wear or damage and taking quick action to fix any problems.

Main types of ventilation

The bathroom’s ventilation can be:

• natural;
• forced.

Conventional air convection powers the first one. Naturally, heated air masses always rise beneath the bathroom ceiling. The air travels higher if there is a ventilation hole with an outlet to the ventilation duct in the upper portion of the bathroom or toilet. A natural draft is produced in the space as a result of the door drawing in new volumes in place of the ones that have left. There is consequently a continuous exchange of air.

Natural ventilation provides air circulation.

The second one functions because the bathroom has a fan that brings in more air or draws it in. In situations where natural ventilation is unable to provide the necessary amount of air exchange, forced ventilation is installed. These systems, however, are dependent on energy. It is advised that you install them in your home bathroom as a last resort.

The forced ventilation principle

Three categories of forced ventilation exist:

1. Supply.
2. Exhaust.
3. Combined (supply and exhaust).

In the first scenario, a running fan draws air from the ventilation duct into the room. It is forcefully drawn (sucked out) into the ventilation shaft from the bathroom and toilet in the second system. Combining the first two ventilation systems is the third option.

More about types of ventilation

To begin with, let’s review the fundamentals of ventilation. There are two varieties: natural and forced. Since many of them have precisely this type of ventilation, let’s start with the last one.

You can see that bathroom hoods come in a variety of sizes and shapes by examining the photos. all because each home may have a different air channel in which they are placed.

A natural ventilation system, which relies on the temperature differential between the air inside and outside the house, is installed in both modern and older Soviet-style homes. Such ventilation has the benefit of not requiring electricity to function, but the drawbacks are far more substantial.

First of all, air movement, which regulates temperature, is significantly hampered by a significant increase in street temperature. Furthermore, such ventilation gradually loses a great deal of its productivity in the absence of routine cleaning.

Because of this, people who live in homes with natural ventilation use exhaust fans in their bathrooms and, if needed, other rooms.

This is because natural ventilation may not always be sufficient to eliminate the increased humidity in the bathroom, which needs to be done.

Right now, forced ventilation is the best choice. For air circulation, ducts are also necessary, but you have the option to install them yourself. You can stop worrying about the weather and the heat outside because it no longer functions on temperature variations.

The only thing left to do is choose the appropriate fans for each room that the ventilation system will be connected to.

One drawback is that each fan must have its own connection to the electrical supply system in order for it to operate; otherwise, it cannot.

However, given that we live in the twenty-first century, having no power for days at a time is more of an extreme circumstance than a daily occurrence. As a result, the system’s need for electricity is perfectly normal.

Types of exhaust fans

There are two categories of modern bathroom hoods that are intended for installation: simple and automatic. Their designs, extra features, and prices are different from one another. For a separate room, the hood should provide 25 m3 of fresh air per hour; for a combined bathroom, it should provide 50 m3.

The basic apparatus consists of an electric fan housed in a plastic tubular housing. There are two varieties available: freestanding and built-in.

Automatic exhaust units are easier to use and require the room owner to be involved in the air exchange control process to a minimum.

One common method of activating the device is by flipping the bathroom light switch. When a person is using the restroom, this option permits the removal of contaminated air from the space.

Electronics installed in automatic equipment allow for effective control over the device’s operation.

Moisture cannot quickly escape from the space, so it is preferable to install an independent switch.

Hoods may be fitted with extra features, such as:

• shut-off timer
• humidity sensors;
• color backlight.

As soon as the humidity level exceeds what is allowed, the fan is turned on. Once this parameter returns to its normal state, the device shuts off.

Automatic models are practical and user-friendly appliances that operate the ventilation system without the apartment owner’s intervention.

Other features can be added to automatic products. A fan on the supply pipe with an adjustable diffuser won’t hurt the owners of private homes because their ventilation system is directly connected to the street.

A check valve installed in certain models prevents air from flowing in the other direction. Apartment dwellers in high-rise buildings can shield themselves from the smells of their neighbor’s bathroom by using this option.

The bathroom exhaust system is simple to design, but it does its job well and performs as intended.

The forced principle of action is used in modern bathroom hood installations. The apparatus is made up of a duct and a fan that are attached to the building’s ventilation channel.

The comparatively simple design of the axial exhaust fan has no bearing on how well it works. Its performance can be comparable to that of air conditioners.

It is essential to consider the unique features of the bathroom as well as the different types of ventilation systems that are currently in place when selecting the ideal hood. The devices may vary in terms of power, additional functions, design, and working principle.

Types of fans for closed rooms

Toilets and combined bathrooms are the two types of equipment used in bathrooms. These exhaust units are radial and axial. The second one is also known as centrifugal.

A traditional impeller is mounted on an axis, which is represented by an axial device. Its blades have an angled construction. The shaft rotates, drawing in the airflow. If the fan’s head generation is adequate to maintain regular air exchange, this fan is used.

Purchasing a domestic axial fan makes sense for owners of homes and apartments. It enables the room to be comfortably decorated with the least amount of money.

When using radial units, the airflow is drawn into the center and exits through a blade-adorned casing. The air masses are forced to the housing’s edges by centrifugal force and rarefaction as a result of their placement in the center, where they are released into the ventilation duct via the outlet pipe.

The most widely used models are overhead ones because they can evacuate volumes that axial models cannot, and they operate far more quietly and efficiently. Centrifugal fans are separated into basic and upgraded models based on the level of equipment. The second has an automated mode of operation.

A timer and sensors are additional features found on automatic centrifugal products. They provide the room’s owner the ability to manage how the apparatus functions.

When it comes to outfitting your bathroom with a hood, it"s crucial to understand the selection rules and installation features to ensure optimal performance and safety. The bathroom hood, also known as an extractor fan, plays a vital role in maintaining good air quality by removing excess moisture, odors, and pollutants from the space. When choosing a hood, consider factors like the size of your bathroom, the level of ventilation needed, and energy efficiency ratings. Installation should be done by a qualified professional to ensure proper positioning and connection to the ventilation system. Proper maintenance, including regular cleaning and filter replacement, is essential for keeping your hood functioning effectively over time. By following these guidelines, you can create a comfortable and healthy bathroom environment while maximizing the efficiency of your heating and insulation efforts throughout the house.

Main parameters of the bath hood

Because bathrooms are unique, designers have created gadgets that are made for extremely humid spaces. Since the fan runs on electricity, its casing needs to be hermetically sealed. The equipment’s internal construction is dependable shielded from the effects of moist steam on all sides.

Attention to the characteristics of the device

The International Electrotechnical Commission has created a standard for consumers to follow regarding the dependability of electronic devices. It has two digits and is labelled IP.

The first’s value, which ranges from 0 to 6, represents the level of defense against impurity penetration. The degree of moisture protection is indicated by the second digit. The figure needs to be at least 4 in order to use the product in a bathroom.

Every product needs to be accompanied by a certificate indicating its level of safety. It is preferable to select an appliance for the bathroom with an IP number higher than 34.

Performance and capacity are closely associated. The second indicator will be greater the higher the first one. The performance indicator can be calculated by multiplying the bathroom’s meterage by the total number of occupants in the home.

A fan with many extra features may have a capacity that is up to 10% higher than the estimated capacity. The most widely used are low-cost, nearly silent devices with power consumption ranging from 7 to 20 watts.

When high power devices are used, the room will not warm up enough and will be drafty.

The amount of noise produced by the appliance’s blades while it is in use is another crucial feature. It makes a lot less noise than when a kitchen hood is running. The standard acceptable sound level for an extractor fan is 30 dB or less. This is because sounds louder than 35 dB are perceived by humans as bothersome and invasive.

Timer, hygrostat, check valve

Conventional bathroom fans run in a slow, steady mode or are mechanically operated. An extra tool that lets you partially automate the process is a timer.

Because of a timer, the exhaust fan keeps on removing exhaust air from the bathroom after a person leaves. When it’s finished, it turns itself off.

The following article goes into great detail about these challenging problems and provides instructions on how to install and connect the extractor unit to the regular switch.

An apartment or home’s typical microclimate is not supported by the smells of cooking food, steam fumes, or smoke. It is advised to install hoods in the kitchen and bathroom to address this issue.

The ideal solution for the bathroom is the presence of a humidity sensor. The best control method is a hygrometer, which lets you set the humidity threshold from 40 to 100%, at which point the fan turns on automatically. It is uncommon to use a timer and hygrostat simultaneously. Generally, if a humidity sensor is available, a timer is not needed.

Measure the bathroom opening or bathroom opening when installing ventilation in a country home. This will help you figure out the ductwork’s diameter. The extractor hood’s standard fitment size is between 100 and 130 mm. A hole punch can be used to enlarge the hole in the bathroom wall if needed.

The best course of action is to choose a ventilation unit of the necessary size to guarantee regular air exchange and a comfortable interior climate.

A check valve is a tiny, simply designed device that keeps foul smells from nearby apartments from entering your apartment. In urban baths and bathrooms that are connected to a common ventilation duct, it is practically essential.

Ventilation and ventilation systems equipment

A ventilation duct to the common shaft (riser) and a wall grille are part of the traditional ventilation system in the restroom and toilet. Furthermore, filters are frequently installed in the ductwork. However, it must be present in the fan if the ventilation system is forced. Additionally, a control unit and other automatics have already been added to this equipment.

One ventilation channel is sufficient if supply or exhaust ventilation is the installation’s chosen mode. Between the restroom and the street, two separate ducts are needed for the combined supply and exhaust version. They will be utilized for air extraction and supply, respectively.

Options for designing with a duct or axial fan

For forced ventilation systems, duct fans are:

• Axial – air movement occurs along the axis of the motor;
• radial – the air flow inside is created with an inclination to the axis of the special bent forward or backward working blades;
• Centrifugal – air flow is generated by creating a pressure difference inside the casing.

An axial fan, which frequently comes in a single set with a ventilation grille, is the easiest to install. When the ventilation system is still in use, it is the simplest to maintain. To reduce noise from the grille, radial versions are often installed inside the duct at a specific distance from it.

Axial fan types used in forced ventilation

Their lower power consumption and greater efficiency set the centrifugal counterpart apart. Installing this fan is preferable if ventilation is required in a bathroom that is larger than 15 square feet.

An electric heater or recuperator is another feature of the supply system. The street must provide the necessary air, and it is initially chilly there. Therefore, these air masses are slightly preheated in the ventilation ducts so that the heating doesn’t require additional power.

Checking the ventilation system

It doesn’t matter if you live in an apartment or a private home; in the case of a natural ventilation system, it is imperative to diagnose it before installing an extractor hood.

However, it’s likely that you didn’t install natural air conditioning if your house wasn’t built very long ago. In such a situation, a private home must have an extractor hood.

In any event, it is imperative to verify that the ventilation system is, at minimum, functional. You’ll need matches or an ordinary candle for this. Keep an eye out for movement when bringing the fire to the ventilation.

If the room has adequate and functional ventilation, the fire should be directed toward the ventilation opening. If not, you must determine where the issue is coming from.

Most of the time, the issues are very minor; for example, a blocked ventilation system needs to be avoided. Another common reason is the use of low-quality plastic windows.

You see, one crucial function of wooden windows is that they don’t obstruct the flow of air within the space. But occasionally, the airflow is disrupted when wooden windows are swapped out for plastic ones. This occurs as a result of the new window’s highly undesirable lack of vents.

How to choose the right appliance?

A ventilation system for the bathroom will require the selection of an exhaust device. It is first necessary to ascertain its capabilities, which include the capacity to propel a given amount of air. The appliance’s diameter determines this indicator.

Devices with pipe cross sections of 80, 100, 120, or 150 mm are available from manufacturers. The ideal diameter for Khrushchevka will be 80 or 100 mm. Apartments in newly constructed buildings have better layouts; in this case, a 120 mm cross-section is a good place to stop.

A factor of equal importance is appearance. A lot of manufacturers make hoods with removable exterior panels. Fans from brands like Ballu, Timberk, Electrolux, Elicent, and others are available in a range of hues.

The benefits of hood models with detachable panels include the device’s ease of maintenance and the opportunity to execute daring design concepts.

A fashionable and eye-catching gadget can be integrated into the interior as an accent piece or positioned so that it is not visually conspicuous. When making a decision, keep in mind that water and electricity shouldn’t come into contact because the fan will need to operate in extremely humid conditions.

Experts advise using a product made for long-term use in such rooms to prevent wiring issues.

Verifying the device’s noise level is reasonable because unneeded and unpleasant noises can irritate the hearing. A high-quality bathroom fan operates almost silently.

You can hear a faint air movement occurring in the device’s body tube when you turn on the silent exhaust unit.

It’s important to consider the device’s dependability and longevity as well. There aren’t many bathroom fan manufacturers who can promise that their models will last for several years. The manufacturer’s warranty period attests to high quality. Purchasing this device is not advised if it will be used for less than a year.

Criteria for selecting equipment

There is a large selection of forced and natural ventilation equipment on the market. Small-sized household fans are the only kind of exhaust devices that are appropriate for use with toilets and bathrooms. These gadgets come in a huge variety. There is a hierarchy among them based on the installation technique, air injection design and principle, and functionality. But performance is the primary criterion for selection.

This is an indicator that shows the device’s capabilities. Its objective is to induce forced air circulation, which allows the air to exit through the ventilation duct. The amount of air masses the device can pump in an hour is indicated by its capacity. The steps to accurately calculate the needed value for a given room are outlined below.

The most important technical characteristics

Along with performance, it’s important to consider the following aspects of the fan:

• installation diameter (otherwise: spigot diameter);
• power (or energy consumption)
• noise level;
• electrical safety class.

Style and design are examples of secondary traits. These are also significant, but not enough to influence the decision. Lovely, useless, low-power appliance.

The installation diameter shows the size of the hole in the wall needed to fit the fan. The appliance’s rear, projecting section is called the spigot. It must match the cross section of the ventilation duct when it is inserted.

The power rating indicates the maximum force of airflow that the fan can produce. The device uses more electricity the more powerful it is. These two parameters are therefore identical and dependent on each other.

The amount of noise the operating fan makes is a crucial feature. This number shouldn’t go above 40 dB in small spaces like restrooms and loos. Louder noises are exhausting and irksome.

The electrical safety class of a device denotes the level of protection afforded to its electrically powered motor (or motors). High humidity and splashing can result in a short circuit, which can start a fire. All products powered by electricity must adhere to standards that have been adopted in order to prevent this issue. IP44 class is for domestic fans.

Options that increase the functionality of fans

Three fundamental components make up the most basic fan:

• motor;
• Axles or wheels with blades;
• Grid-type or solid front panel.

This kind of device does exactly what it’s supposed to do: it lets the air in the room exchange. However, more features added to more recent models give owners a great deal of control over the device and its programming. Pricey hoods can be fully automated, doing away with the need for manual on/off switches.

1. Power regulator. Allows you to save electricity.
2. Air humidity sensor. Necessary for programming the unit.
3. Motion sensor. Allows the fan to operate automatically under certain conditions.
4. Timer. Necessary to program the appliance.
5. Check valve. Prevents air from entering from a wall or ceiling vent. Electric bathroom extractor hood with check valve – the best choice possible.

Installation options

There are three ways to mount fans in homes, and these kinds of devices are categorized into three groups based on which method is chosen:

• Wall-mounted;
• recessed;
• ceiling.

The first category exhaust units’ design calls for them to be positioned on the wall with their backs facing the ventilation duct. As a result, they extend past the wall plane, which could be detrimental to the room’s design.

Integrated models are preferred by those who wish to conceal the device’s existence as much as possible. Their front panel thickness—which could be as little as a few millimeters—is the only thing that separates them from the wall.

The most fashionable models are those that are mounted on the ceiling because of their prominent and well-lit placement. installed, including on stretch ceilings, on any surface.

Calculation of the minimum required capacity

The air exchange rate must be known in order to accurately compute the exhaust unit’s technical specifications. This number indicates how many times new air should replace "old" air in an hour. These standards are laid out in SNiP. Depending on the circumstances of use, the multiplicity for restrooms and sanitary rooms should be either 6 or 8.

A 6-fold replacement is sufficient if fewer than three people use the room on a regular basis. Select the 8-fold option if the apartment or private home is shared by more than one person.

Determine the room’s volume before calculating the fan’s performance requirements. To accomplish this, multiply the room’s length, width, and height in turn. The multiplicity discovered is then multiplied by the number that was obtained. Consequently, the device achieves the necessary performance.

Choosing a fan

You can choose the fan if everything with the ventilation system is in working order. Prior to considering how to build a bathroom hood, consider the size and shape of the existing hole. All because you will choose a fan that fits the channel based on these data.

You’ll see that there are many options in the store, but how do you decide? It should come as no surprise that a quiet bathroom hood will always be more expensive than the most popular choices. You have the final say in this matter because noise level is a significant factor in such purchases for some individuals.

Both the fan and the grille that covers it from the outside are typically sold by the store. However, since the decorative grate can be bought separately if the complete set isn’t to your liking, it’s crucial to base your decision on the fan’s quality.

Ultimately, in order for the hood to function, it must be connected to the network. There is a small workaround: the hood can be wired to the bathroom light switch so that it activates when a person enters the space, though this is not the best solution.

Whether you have installed the most common fan or a bathroom hood with a check valve, the outcome is almost always obvious and there is nothing complicated about it.

Selecting a model

It is important to choose the primary functional product—the fan—with extreme care so that the exhaust vent operates as efficiently as possible. As a result, it’s essential to gain a deeper comprehension of the specific elements that will make determining the type of ventilation design easier.

Ventilation scheme

Noise level

It is normal for household appliances to make some noise while they are in use. This indicator is always present on ventilation equipment according to its passport. Installing a system of approximately 35 decibels, which is regarded as a high level of noise isolation because this sound is undetectable to human hearing, is possible in bathrooms and restrooms. Because of their annoyance, fans with higher sound values are already regarded as inappropriate for use.

Power-controlled fan

Engine

The bathroom gadget should have the required power and a substantial durability reserve. It is the fan motor’s responsibility to manage these parameters. Its design should be taken into consideration right away during inspection. Ball bearings and installed bushings are required; the latter two are dependent on how long the engine runs for and how much noise it makes. To be fair, these models are thought to be the most silent, long-lasting, and productive.

Strong fan

Performance

This is one of the most crucial indicators for the ventilation system as a whole to function properly. The productivity makes it possible to figure out how much fresh air enters the restroom or bathroom during a 60-minute operation. It should be recognized that the following factors directly affect the fan’s performance:

• the area of the room;
• the level of humidity;
• number of active users.

Exceptional fans

There is a fairly simple formula that can be used to determine the necessary ventilation equipment capacity. To find the value of the number of complete changes in the atmosphere in the restroom, multiply the total volume of the desired room by a multiple of the air exchange, or the index. The approximate multiplicity for a bathroom will be equivalent to an indicator ranging from 7 to 10 units.

Since technology is clearly not stagnating in the modern era, inventive ventilation system examples with the following features are already available on the market:

• automatic connection to the switch;
• independent operation when a certain level of humidity is reached;
• programmed setting of tasks according to various criteria.

Tips for installing ventilation in the bathroom

The exhaust version of forced ventilation is typically installed in apartment bathrooms and toilets. In order to accomplish this, a small axial fan with the necessary capacity is fixed in the existing ventilation duct. There are already air ducts; they cannot be expanded upon or entirely replaced with new ones. The only thing left to do is put an exhaust fan in them if needed.

Plan for installing forced air conditioning using a shared ventilation shaft

You can select any kind of bathroom ventilation for a cottage. However, even in this situation, if the house has already been constructed, a system with a traditional duct exhaust is typically installed. It is less expensive and simpler to make by hand than others. This is not a well-supplied water supply for the device; installers with specialized equipment must be invited. You can do it on your own here.

It is simple to add an electric fan to the bathroom’s existing natural ventilation system to boost effectiveness. All that needs to be done is accurately determine its capacity.

1. Remove the ventilation grille.
2. Clean dust and dirt from the ductwork.
3. Cover the fan housing with polymer glue and put it in place in the channel.
4. Connect the electrical wiring to this device.
5. Install a mosquito net and a front cover.

An electrical schematic of a forced-air bathroom

Punching them out will be required if the room lacks ventilation ducts. Nonetheless, it is imperative to accurately determine their dimensions and installation location in advance. It is preferable to leave the bathroom ventilation design to a professional in this kind of circumstance. The air exchange in the entire house, not just the bathroom, must be considered in this situation. Without the necessary information, it is unlikely that calculations can be completed accurately and correctly.

Choices for setting up the air conditioning system

If you are doing everything by yourself, positioning the grille under the ceiling across from the entrance door will allow for the greatest amount of draught to be created in the ventilation channel. In restrooms, ventilation is typically installed in this manner.

The ventilation system should be set up to minimize internal duct bends. To ensure optimal performance and minimal noise, the fan to be installed inside the ventilation duct must be precisely the correct size.

Construction components for the ventilation system

Placing ventilation equipment close to heating appliances is also a bad idea. Since the fan warms up during operation, it is not recommended to use additional heat from other devices.

Preparing the place for the extractor fan

There are several preparatory tasks that need to be completed before installation. First, you must place a lit match or candle against the inlet opening to see if the ventilation channel is operating correctly. The flame ought to be facing the grille.

You must act quickly to clean the unit before installing the hood if the lit flame suggests that the ventilation duct is clogged.

If the diameter of the vent hole is greater than the fan’s cross-section, you can insert a plastic or corrugated pipe that is the necessary diameter and fill the spaces with assembly foam. Once the mortar has set, trim off any excess foam with a sharp knife.

If the hole at the shaft’s entrance is smaller in diameter, a perforator is used to enlarge it.

Selecting the optimal connection scheme

Determine how the exhaust fan will be connected to the power source before installing any model in the bathroom.

Currently, there are various methods for connecting the hood:

1. The switch is located on the body of the unit. In this case, it can be switched on or off by means of a button or a lanyard on the housing.
2. Connecting the appliance to a separate switch. A switch is installed in front of the bathtub, where one of the keys switches on ventilation and the other switches on lighting.
3. Automatic switching on of the fan by a humidity or motion sensor. It starts to function if the permissible level of humidity is exceeded or there is movement.
4. The device is connected to the light switch. It can be equipped with a timer and connected in parallel to the luminaire. Turns on at the same time as the lights and turns off when the lights go out.

Since apartment dwellers frequently use the restroom for brief periods of time to swiftly wash their hands, brush their teeth, or wash their faces, the final method of connecting the device is less common. The turned-on hood will waste electricity in these situations.

The ventilation system’s connection to the light switch is rarely used because most people find that using a fan while relaxing or taking a bath interferes with their ability to unwind.

It is preferable to install the wiring beneath the tiles. If this isn’t feasible, you can cover up the cable with customized plastic containers.

Procedure of installation works

Read the instructions carefully as they outline the precise installation procedure before hooking up the bathroom fan. The chosen hood model is installed in the sanitary room or bathroom in compliance with the recommendations.

A specific order is followed when performing actions:

1. First, remove the front cover and apply liquid nails, silicone or polymer adhesive to all areas where the product adjoins the wall surface. These materials will ensure that the relatively lightweight plastic is firmly attached.
2. Insert the device so that the working part together with the electric motor is completely in the wall. Press firmly against the attachment point for a few minutes.
3. We put a mosquito net, which will not allow various insects and gnats to penetrate into the room.
4. Attach the front cover with self-tapping screws, which are included in the kit. this action is carried out in the last turn.

There shouldn’t be any exposed, bare wires in the room when connecting to the power supply. They are covered with corrugated iron and inserted into underground ventilation ducts.

There are safety precautions to take when attaching the hood to the power source. First and foremost, you need to confirm that the room’s electricity is off. When connecting wires, use more dependable terminal blocks as opposed to twisted ones.

Many users wire fans to light switches using a contact pair. Put the phase switch in place.

You can install a separate key to turn on the hood for future convenience when using the appliance. It is convenient to control the lighting with a single key if it is not needed when using the restroom. then the sound of whirring blades won’t disrupt the ambience of the space.
