3. How to install the indoor unit
3-3-2. Suspending the Indoor Unit
Depending on the ceiling type:
• Insert suspension bolts (Fig. 2-41)
or
•
Use existing ceiling supports or
construct a suitable support (Fig. 2-42).

It is important that you use extreme care in
supporting the indoor unit inside the ceiling.
Ensure that the ceiling is strong enough to
support the weight of the unit.
Before suspending the unit, test the strength of
each attached suspension bolt.
(1) When placing the unit inside the ceiling, determine
the pitch of the suspension bolts referring to the
dimensional data as shown in Fig. 2-39 and Table 2-4.
Tubing must be laid and connected inside the ceiling
when suspending the unit. If the ceiling is already
constructed, lay the tubing into position for connection
to the unit before placing the unit inside the ceiling.
(2)
Screw in the suspension bolts allowing them to
protrude from the ceiling (Fig. 2-41).
(Cut the ceiling material, if necessary.)
(3) Thread the 3 hexagonal nuts and 2 washers (field
supply) onto each of the 4 suspension bolts
(Figs. 2-43 and 2-44).
Use 1 nut and 1 washer for the upper part, and 2
nuts and 1 washer for the lower part, so that the unit
will not fall off the suspension lugs.
