12. Warranty and maintenance
Our product design is maintenance-free, but in order to ensure the long life of the normal operation, the fan
should also be maintained regularly, especially when applied in harsh environments.
For any fan or inverter controller maintenance, please be sure that the fan stops running and cut off the controller
power to protect the safety of personnel.
If the fan is running with a serious abnormal noise or vibration, it indicates that there exists some damages to the
mechanical parts somewhere, and you should immediately shut down the fan and do a comprehensive inspection.
