What Are The Installation Precautions for Exhaust Fans?

Preparation before installation

1. Check the fan components: Before installation, carefully check whether the exhaust fan is intact and intact, whether the fastener bolts are loose or fallen off, whether the impeller has collided with the windshield, and whether the fan blades or louvers have been deformed and damaged during transportation.

2. Confirm the basic conditions: To ensure that the installation foundation has sufficient strength and appropriate size, the fixing screws must comply with the fan installation dimensions. In addition, it is also necessary to check whether the positions and installation dimensions of the air inlet and outlet at the installation location are relative.

3. Check the circuit and environment: Check the circuit and environment: Check whether the power supply voltage, switches, etc. comply with electrical regulations, and whether the wiring is correct. At the same time, the installation location should be as empty as possible to facilitate air flow, avoid building obstructions in front of the exhaust fan shutters, and should not be installed in a smelly location. Or the exhaust port of odorous gas.

Key points of the installation process

1. Ensure stable installation: During installation, attention should be paid to the horizontal position of the exhaust fan, and the exhaust fan should be adjusted to be level and stable with the plane of the foundation. The motor should not be tilted. The mounting bracket should also be level and stable with the plane of the foundation. If necessary, angle irons can be installed for reinforcement.

2. Ensure good sealing: The wall on the exhaust fan side must be sealed, especially there should be no gaps around the exhaust fan. Sun panels/glass glue/foaming agent, etc. can be used for sealing.

3. Pay attention to the installation height and distance: the exhaust fan can be installed on indoor walls, windows, roofs, etc., but the air must be kept clear and fresh. If possible, it should be installed in the upper direction of the dominant wind in the cooling environment.

Inspection and debugging after installation

1. Check the internal debris: After the installation is completed, check whether there are any leftover tools and debris inside the exhaust fan. Move the fan blades with your hands or levers to check whether they are over-tightened or rubbed.

2. Confirm the direction of rotation: Before use, check whether the rotation direction of the fan blades is consistent with the exhaust fan mark.

3. Check the circuit safety: Have professional electricians perform power distribution. The control switches must have functions such as defect protection, leakage protection, and current overload protection. The wires and cables used must be able to withstand the load of the motor current. All wire joints must be wrapped with electrical tape for nsulation, all lines are buried in wire troughs and conduits in accordance with regulations.
