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.
(1) If the full-scale installation diagram is placed on the ceiling,
the locations of each suspension bolt can be chosen.
Take a pencil and mark the drill holes (Fig. 3-9).
