2. Carefully check whether the fan is deformed or damaged during transportation, whether the solid parts are loose or falling off, whether the impeller has a rubbing phenomenon, and check all parts of the fan. If an abnormality is found, it should be repaired before use.
3. The insulation resistance between 500V megger fan housing and motor windings, which should be greater than 0.5 megohms, or respond to the motor windings powerful horse drying process, when the drying temperature must not exceed 120 ℃.
4. Prepare the various materials, tools and sites required for fan installation. Http:// http:// http://
