1. After the axial fan is installed, check the flexibility of the fan rotation before starting, and if there is any friction in the blade by hand. Check for any leftovers and other debris in the fan and adjacent pipes.
2. Check if the damper in the pipeline is open.
3. Personnel should stay away from the fan.
4. Start the fan and check whether the fan blade is in conformity with the rotary marking. After the inspection is passed, stop the test after 10-30 minutes, check whether the blade is loose or not, and whether the vibration-damping seat and the bottom connecting bolt are loose. After everything is normal, it is officially launched and put into operation.
