Usually, carefully check whether the fan is deformed or damaged during transportation, whether the fasteners are loose or falling off, and whether the impeller is rubbing.

When installing the fan, pay attention to the horizontal position of the fan, and the connection between the fan's foundation and the ground and the connection of the air outlet pipe should be adjusted so that they fit naturally and must not be forcedly connected.

The steel bracket of the fan must be fixed on the concrete foundation, and a rubber damping pad must be added between the fan's steel bracket and the foundation.

The pipe diameter of the fan outlet can only be enlarged and cannot be reduced. An insect-proof net must be installed at the air outlet, and a rain cap must be installed when the air outlet is upward.
