There is no wind after the fan is installed. What is the reason?

1. Whether the fan is reversed (from the side, the fan turns from right to left, and vice versa), the reverse wind is upward. If there is a positive and negative model, just flip the positive and negative switch to solve the problem; If this model does not reverse, it is the fan factory is connected to the wrong wire.

2. Whether there is a ceiling at the installation of the fan, if there is, the derrick must be lengthened, and the standard is: the blade position must be below the ceiling more than 20 cm before the wind is normal; If the installation area is too small, the wind will also be affected. If the factory fan is rotating fast and positively, there will be wind during normal installation.
