1. The installation of general exhaust fan systems and air conditioning systems should be carried out after the construction of the building enclosure structure is completed, obstacles have been cleared, and the ground is free of debris.
2、作业地点要有相应的辅助设施，如梯子、架子、安全防护、消防器材，并有施工员的技术、质量、安全交底。
2. The work site should have corresponding auxiliary facilities, such as ladders, shelves, safety protection, fire equipment, and technical, quality, and safety briefings from construction workers.
3、对空气洁净系统的安装，应在建筑物内部安装部件的地面做好，墙面已抹灰完毕，室内无灰尘飞扬或有防尘措施的条件下进行。
3. The installation of the air cleaning system should be carried out on the ground where the components are installed inside the building, with the walls plastered and no dust flying or dust prevention measures taken indoors.
4、一般除尘系统风管安装宜在厂房的工艺设备安装完或设备基础己确定，设备连接器、罩体方位已知的情况下进行。
4. The installation of air ducts for general dust removal systems should be carried out after the installation of process equipment in the factory or when the equipment foundation has been determined, and the orientation of equipment connectors and covers is known.
5、 检查现场预留孔洞位置;尺寸应符合图纸要求，每边比实际截面大100mm。
