NOTE
Since the diagram is made of paper, it may shrink or stretch
slightly because of high temperature or humidity. For this
reason, before drilling the holes maintain the correct dimensions
between the markings.
(2) Drill holes at the 4 points indicated on the full-scale
diagram.
(3) Depending on the ceiling type:
