When installing the fan, pay attention to the following points:

1. Before opening the box, the fan should check whether the package is intact and undamaged, whether there is oil leakage and moisture phenomenon, and clear the dust inside and outside the fan box after opening the box.

2. When installing the fan, it must be installed in accordance with the basic requirements provided by the design department or manufacturer, and pay attention to the weight of the pipeline of the outlet and the inlet should not be borne by the fan casing, and it should be supported by another one.

3. Before the trial operation, carefully check whether the fan has deformation or damage during transportation. 4. Before test run, carefully check the fan for deformation or damage during transportation, loosening of parts, motor shaft rotation is flexible, whether the voltage is in line with the determination of the correct, before test run.

4. As the fan's flow Q, full pressure H, spindle speed n, shaft power N have a fixed relationship between the four, so in the capacity of the motor does not change when the spindle should not change the number of revolutions, otherwise the motor is in danger of burned due to overloading.
