Do you know what are the precautions for the installation of ventilation fans? Have you noticed that sometimes you feel very suffocated at home, and you can't tell what is uncomfortable, but as soon as you go outside to breathe fresh air, you will instantly feel better! This situation is usually caused by poor indoor air circulation! Ventilation fans are used to improve indoor air and promote indoor air circulation! Therefore, many friends now choose to install ventilation fans at home! Today, Xiao Wan will share with you the precautions for the installation of the ventilation fan and the installation location of the ventilation fan!!

1. Precautions for installation of ventilation fans

1. The ventilation method of the ventilation fan is different, and its meaning is different. When the ventilation fan is fully ventilated, the ventilation fan is used to replace the air in the whole room to reduce the degree of indoor air pollution.

2. When the ventilation fan is a partial ventilation, the ventilation method is to ventilate a part of the room or part of the household. When exhausting gas from kitchens, baths, toilets, toilets, etc., ventilators are used to ventilate locally in places where polluting substances (combustion gases, moisture, smoke, odors, etc.) occur. If it is a separate room such as a living room, it is a separate exchange of individual objects.

3. Read the manual carefully before use, and the ventilation fan should be able to start smoothly after the power is turned on; If the ventilation fan still does not rotate after being connected to the electricity, check whether the fuse connected to the motor is disconnected, and whether the wiring is correct and firm. If it does not rotate after ruling out the above reasons, you should find an electrical professional for inspection.

4. The ventilation fan should be installed at a height of more than 2.3 meters from the ground and not close to the high temperature source, and the installation must be reliable and firm.

5. When using the socket for power supply, the power cord of the ventilation fan should be matched with a plug that meets the safety standards.

6. When the power cord of the ventilation fan is directly connected with the power supply line, an omnipolar power switch with a contact opening distance of at least 3mm should be installed on the power supply line.

7. The yellow and green two-color wire in the power cord is the grounding wire, which must be well grounded, and its wiring should be carried out by electrical professionals. When disassembling or cleaning the ventilation fan, the power supply must be cut off first.

8. The ventilation fan must ensure that the power supply has been turned off before maintenance or repair. Do not use water to clean electrical parts such as switches and motors. The cleaning of metal paint or plastic parts can be cleaned with a soft cloth dipped in soapy water, and organic solvents such as benzene and gasoline should not be used.

9. The plastic parts of the ventilation fan, especially the fan blades, shall not be soaked in hot water higher than 60 degrees. If the motor is found to be faulty in operation, the power supply should be cut off, and the maintenance personnel should be asked to check and repair. When there is a product quality problem with the ventilation fan, please find a normal after-sales service and maintenance channel.

Second, the installation position of the ventilation fan

1. The key position of the ventilation fan and the ventilation dam

(1) When ventilating as a whole, try to set up an air supply port away from the ventilation fan. In the case of partial ventilation, due to the small space of the ventilation object, try to set up a vent close to the ventilation fan to reduce the impact on other aspects.

(2) It is suitable for buildings, parking lots, boilers, power supply rooms, machinery rooms, kitchens, warehouses, etc.

2. Install a ventilation fan in the bathroom or toilet

When installing ventilation fans in bathrooms and toilets, vents must be installed (except for the simultaneous supply and exhaust method). It is suitable for clean rooms, toilets, mechanical cooling, etc.

3. Install a ventilation fan in the room of the semi-sealed burning appliance

In cold places, when a stove with a chimney is installed without a proper ventilation, once the fan is used, the chimney becomes a vent, and the exhaust gas is dangerous to flow back into the chamber. It is suitable for residential buildings such as houses, toilets, and boiling water rooms, as well as coffee houses.

The above is the sharing of the precautions for the installation of ventilation fans and the installation location!! Please note that when installing the ventilation fan, it should be based on the purpose of installation, installation location, installation height and so on! You can read the article again for details!! The installation location of the ventilation fan is also very important, so you should ask a professional when choosing!
