1. Pre-installation check carefully whether the blades have been damaged due to transportation or deformed, whether the screws are loose connections, chassis deformation, the impeller and the casing is grazing, the gap is uniform, the power connector is loose or should before installation after the repair.
2. Before starting the fan, you should first check whether or interfere with the rotation of the object around the installation angle of the four blades are the same, or should be adjusted.
3, the fan motor running in case the temperature exceeds 75 ℃, motor smoke, excessive vibration and the larger end of the run that grazing should sound, and then repair.
4, motor bearing damage, with the gap is too small, the shaft and the bearing mounting skew, pipe resistance is too large too low voltage electric current that may cause the motor to generate heat, should be adjusted.
5, the fan does not use long-term, should be placed dry place to prevent moisture damage to the motor.
6, ducted fan only allows horizontal mounting.
