Use and Maintenance：

Before installing the fans, should check whether each part is intact, whether the components are complete, whether the impeller and casing

rotating direct are concordant.

After installed the fans, check whether there is friction of collide between the impeller and the fixed parts by rotating the impeller. If collision,friction, loud noise or strong vibration happened, the fan should be restart after checking. Avoid the fan being bumped and other substance or liquid enter the fans.Please dean the dust on blade of impeller in time. so as not to break the balance and strengthen the noise.

The fans maintain must be done on stop working time. When burning, after check, should whether the every part of fans is normal.
