Important Note:

 

● Rated Current: Rated Current shall be measured after 3 minutes of continuos rotation at rated voltage.

● Rated Speed: Rated Speed shall be measured after 3 minutes of continuos rotation at rated voltage

● Start Voltage: The voltage which is able to start the fan to operate by suddenly switching “ON”

● Dropping test standard: Drop a minimum packing box in a height of 30 cm for perpendicular free falling motion to the surface of wooden plate of 10 cm. After test, connect the fan to the power, the fan still in normal operation.

● Please do not touch and push fan blade with fingers or others. Fan blade and ball bearings may be damaged. And it caused noise defect. 

● Avoid the damage, check the correct voltage and proper polarity before connecting with power.
