6. HOW TO INSTALL THE INDOOR UNIT
6-2. Suspending the Indoor Unit
Depending on the ceiling type:
• Insert suspension bolts (Fig. 1-34)
or
• Use existing ceiling supports or construct a suitable
support (Fig. 1-35).

WARNING
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 hanging 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. 1-32 and Table 1-8.
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. 1-34). (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. 1-36 and 1-37).
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.

6-3. Installing the Drain Pipe
(1) Prepare standard hard PVC pipe (O.D. 1-17/64" (O.D. 32
mm)) for the drain and use the supplied hose band to
prevent water leaks.
The PVC pipe must be purchased separately.
The transparent drain part on the unit allows you to check
drainage. (Fig. 1-39)
CAUTION
Do not use adhesive tape at the drain connection port on
the indoor unit.
Insert the drain pipe until it contacts the socket, and
then secure it tightly with the hose band.
Do not use the supplied drain hose bent at a 90° angle.
(The maximum permissible bend is 45°.)
