1. 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.
2. When installing the duct of the inlet and outlet, should make the duct and fans be spontaneous identical, not join them forcing, not bring the weight of duct on the fans.
3. 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 entered the fans. Please clean the dust on blade of impeller in time, so as not to break the balance and strengthen the noise.
4. The fans should be started-up while the inlet is opening,
5.After the fans wiring, the terminal box should be sealed, avoid the air or water in it.
6.As the fans operating, the motor electric current should be control strictly, not exceed the rated electric current. Avoid the motor burning,
7.The fans maintain must be done on stop working time. When burning, after check, should whether the every part of fans is normal.
8.As some fault occurred in fans operating, should find out the reason in time and think a way of resolution.
