Installation of ductwork should be conducted after the construction of the building's perimeter structure and completion of site cleanup. Prior to installation, the location, elevation, and direction of the ductwork should be reviewed to ensure compliance with design specifications. The positions of预留孔预留孔 should be accurate, and the size of the holes should be at least 100mm larger than the external dimensions of the ductwork.

When handling ductwork, prevent collisions or drops to avoid damage. Before installation, clean off dust and debris. If there is a pause during installation, seal the duct openings to prevent dust and foreign objects from entering. Duct connections should not be installed within walls or floors, and no pipes, wires, or cables should be laid inside the duct. When connecting the duct to equipment, a flexible short pipe of 150-300mm in length or the specified length should be used at the connection point.

If ducts are used to transport flammable or explosive gases, or are in such an environment, they must have necessary grounding measures for protection; if they are transporting air at temperatures above 80°C, appropriate protective measures should be taken. The bottom of the ducts should not have joints, and if they do, they must be properly sealed. If ducts need to pass through floors or walls, pre-buried pipes or protective sleeve pipes should be used, and they should be sealed with flexible materials. The position of the duct measurement holes should be selected in an area where vortices are not formed, and it should be convenient for measurement and observation.

The ventilation duct manufacturer introduces support and hanger components: All accessories of the support and hanger, as well as the materials used, should comply with design and parameter requirements. Under the maximum allowable installation distance of the duct, the small size of the hanger should meet the specifications. The embedded parts of the support and hanger should be installed correctly and securely, with the embedded portion cleaned and the exposed portion treated for corrosion resistance. Support and hanger should not be placed in the equipment's operating area. When securing the support and hanger, expansion bolts should be used, and their use should adhere to the specified requirements.
