Installation Tips: ♥ Please check the dimensions before ordering, just to ensure it is suitable for your room. ♥ Please note that this crystal fan requires self-assembly, needs patience to put it together, but it will be definitely worth it when you done. ♥ Please check carefully the instruction manual before installation. Ensure the fixture is disconnected from mains power before installation. ♥ You can also replace the down rod as you wish, but we suggest no longer than 45 inches. We suggest you ask a professional technician for help if you are not good at installing.
