Maintenance: 1, the use of the environment should be kept clean, fans keep the surface clean, the outlet should not have debris regularly to remove dust and other debris inside the fan and piping. 2, can only operate at the fan completely normal circumstances, while ensuring an adequate supply facility capacity, voltage stability, non-defect operation, power lines must be dedicated line, not long-term temporary supply line. 3, fans found during operation abnormal noise fan motor severe fever, live shell, switch trip, you can not start and so on, should immediately stop checking. In order to ensure the safety of square wall axial fan, does not allow the fan running repairs, maintenance should be carried out after the commissioning of five minutes or so, confirming that no anomalies start running again.
