1. The installation methods for fire smoke exhaust fans can be horizontal or rooftop type, with specific requirements regarding parameters such as air volume, total pressure, and installation dimensions. 2. Before installing the fire exhaust fan, all its components should be carefully inspected to check for any damage or looseness in the connections; if such issues exist, they should be replaced or repaired promptly. Special attention should be paid to whether the impeller is damaged or worn, whether the gap between the blades and the duct is even, and whether the rotation direction of the impeller is correct. https://zuolidianji.com/uploads/ueditor/20200711/1-200G1111910625.jpg 3. The surface on which the fire exhaust fans are installed must be flat, and it must be 100–200 millimeters above the roof level to prevent water seepage and leaks. The connecting bolts must also be properly secured. 4. After the fire exhaust fans are installed, conduct a trial run. Before transportation, check whether the blade installation angle and motor power match the values specified on the product nameplate. If it does not meet the requirements, use should be stopped immediately to prevent damage to the motor. 5. During use, it is necessary to regularly check whether the operation is normal; repairs should be carried out promptly. After being used for a while, cleaning and dust removal should be performed, and oil should be poured into each lubrication hole for lubrication. 6. Check the tightening nuts to ensure they are secure and prevent loosening. 7. During periods of heavy snowfall and freezing in winter, it is necessary to operate the fire exhaust fans regularly to prevent heavy snow from blocking the fan outlets. https://zuolidianji.com/
