Ensure a thorough understanding and familiarity with the fan samples, including specifications, types, impeller rotation direction, and air flow in and out. Before installation, check for any rubbing between impellers, and inspect all components, ensuring that accessories are complete and connections between parts are secure.Thoroughly inspect the blades for any damage or deformation during transportation; otherwise, wait for repairs before proceeding.Installation underway.

2. Ducts connecting the inlets and outlets of the fan should be supported separately; it is not permitted to add the weight of the pipe to the fan components. During the installation of the fan, attention should be given to the horizontal position of the fan. The junction between the fan and the foundation surface, as well as the connection with the exhaust duct, should be adjusted to ensure a natural and gentle fit, and not to force a connection.

3. After the fan installation, manually or with a lever, rotate the impeller to check for any tightness or rubbing. Ensure there are no items obstructing rotation. Only proceed with the trial operation if there are no abnormalities. The exposed parts of the fan's transmission should be protected with a guard (provided by the user). If the fan's intake is not connected to a pipeline, a protective mesh or other safety devices (also provided by the user) should be installed as well.

4. Ensure the fan wiring is accurate and reliable. The fan housing must be properly grounded, with a reliable grounding connection. The power supply to the fan must be complete and meet all relevant requirements. Electrical wiring must be done by a knowledgeable electrician.
