When entering and leaving the air pipeline, you should adjust it naturally. You must not be forcibly connected.Horizontal position.2. Install strictly in accordance with the position and size shown in the drawings. Pay attention to ensure that the gap between the air inlet and the impeller should be specially ensured.3. When installing the adjustment door, be careful not to install it, and ensure that the direction of the air intake is consistent with the rotation direction of the leaf wheel.4. After installation, try to dial the transmission group to check whether there is too tight or whether it is collided with the fixed part. If the wrong is found, it should be adjusted immediately.

The important thing is to install it. Please ask professional people to help install.Features: 1. Many industrial factories, especially color steel plate buildings, poor heat dissipation conditions, and abnormal heat heat dissipation in summer, resulting in low work efficiency and decline in product quality.Added powerless roof fan can effectively improve indoor air quality, provide a comfortable working environment, and improve work efficiency.2. Many industries, due to the special nature of production, cause air pollution in the factory, not only low environmental quality, but in the long run, employees health must be harmed.However, the driving roof fan is installed, the indoor ventilation effect is improved, which can effectively protect the health of employees.3. In many fire accidents, people are often wounded by thick smoke. If it is installed with powerless roof fan, it can quickly discharge strong smoke and give people more room to escape, so it is also a safety device.
