(2) Mount the canvas ducts to the air outlet and inlet so that the
vibration of the air conditioner will not be transmitted to the
duct or ceiling. Apply a sound-absorbing material (insula-
tion material) to the inner wall of the duct and vibration insu-
lation rubber to the suspension bolts (refer to
8. DUCT
WORK
).
(3) Open installation holes (if the ceiling already exists).
• Open the installation holes on the ceiling. Lay the refrig-
erant piping, drain piping, power line, transmission wir-
ing, and remote controller wiring for the piping and wiring
connection port of the unit.
In the case of the installation of a wireless remote con-
troller, refer to the installation manual provided with the
wireless remote controller.
Refer to
6. REFRIGERANT PIPING WORK
,
7. DRAIN
PIPING WORK
, and
10. WIRING EXAMPLE AND HOW
TO SET THE REMOTE CONTROLLER
.
• The ceiling framework may need reinforcement in order
to keep the ceiling horizontal and prevent the vibration of
the ceiling after the installation holes are opened. For
details, consult your construction or interior contractor.
(4) Install the suspension bolts. Make sure that the suspension
bolts are M10 or the equivalent in size.
• Use hole-in anchors if the suspension bolts already exist;
otherwise use embedded inserts and embedded founda-
tion bolts so that they will withstand the weight of the unit.
Adjust the distance to the ceiling surface in advance.

INDOOR UNIT INSTALLATION
〈
It may be easier to install accessories (sold separately)
before installing the indoor unit. Refer to the installation
manuals provided to the accessories as well.
〉
Be sure to use the accessories and specified parts for
installation work.
(1) Temporally install the indoor unit.
• Connect the hanger brackets to the suspension bolts. Be
sure to use and tighten the nut and washer (11) for each
hanger bracket from both upper and lower sides of the
hanger bracket.
(Refer to Fig. 3)
At that time, the fall of
the washer (11) for the hanger bracket can be prevented
if the washer fixing plate (9) is used.
CAUTION
• During the installation work, perform the curing of the air
outlet and protect the resin drain pan of the indoor unit
from the intrusion of foreign substances, such as weld-
ing spatters.
Otherwise, water leakage may occur as a result of damage,
such as hole damage, to the resin drain pan.
(2) Make adjustments so that the unit will be in the right posi-
tion.
(3) Check the level of the unit.
(4) Remove the washer fixing plates for the falling prevention of
the washers for the hanger brackets, tighten the nuts on the
upper side, and securely fix the unit.
