First, mount the mounting ring to the ceiling in the spot where you want to install the Lightswing®. Use the large holes in the mounting ring for this. Then, place the Lightswing® against the mounting ring and make sure the holes in the base plate of the Lightswing® align with the small holes in the mounting ring. Use a cross-head screwdriver and the 4 screws provided to fasten the Lightswing® to the mounting ring.
