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:
a) Insert suspension bolts (Fig. 3-43).
or
b) Use existing ceiling supports or construct a suitable
support (Fig. 3-44).

It is important that you use extreme care in supporting
the indoor unit from the ceiling. Ensure that the ceiling is
strong enough to support the weight of the unit. Before
Ceiling
hanging the ceiling unit, test the strength of each attached
suspension bolt.
(4) Screw in the suspension bolts, allowing them to protrude
from the ceiling (Figs. 3-43 and 3-44). The distance of
each exposed bolt must be of equal length within 50 mm.
