3. How to install the indoor unit
3-4-3. Suspending the Indoor Unit
NOT E
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. 2-65).
(2) If the full-scale installation diagram is bent at right angle
to the ceiling and wall, the locations of the inlet for indoor
tubing and wiring are chosen and the locations of each
suspension bolt can also be chosen.
Take a pencil and mark the drill holes (Fig. 2-66).
NOTE
The dimension when the indoor unit is placed
tightly against the wall.
When installing away from the wall, drainage
gradient should be taken into consideration.
(3) Drill holes at the 4 points indicated on the
full-scale diagram.
(4) Depending on the ceiling type:
a) Insert suspension bolts (Fig. 2-67).
or
b) Use existing ceiling supports or construct
a suitable support (Fig. 2-68).
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.
WARNING
Before hanging the ceiling unit, test the strength of each attached suspension bolt.
(5) Screw in the suspension bolts, allowing them to protrude from the ceiling
(Figs. 2-67 and 2-68).
The distance of each exposed bolt must be of equal length within 50 mm.
