• Determine the H3
dimension by maintaining a
downward slope of at least
1/100 as specified in
"7. DRAIN PIPING WORK".
(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 (insulation
material) to the inner wall of the duct and vibration insulation
rubber to the hanging bolts (refer to 8. DUCT WORK).
(3) Open installation holes (if the ceiling already exists).
• Open the installation holes on the ceiling. Lay the
refrigerant piping, drain piping, power line, transmission
wiring, and remote controller wiring for the piping and
wiring connection port of the unit.
In the case of the installation of a wireless remote
controller, 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 hanging bolts. Make sure that the hanging bolts
are M10 in size.
• Use hole-in anchors if the hanging bolts already exist;
otherwise use embedded inserts and embedded
foundation bolts so that they will withstand the weight
of the unit.
Adjust the distance to the ceiling surface in advance.

5. 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 hanging brackets to the hanging bolts. Be
sure to use and tighten the nut and washer (11) for each
hanging bracket from both upper and lower sides of the
hanging bracket. (Refer to Fig. 3) At that time, the fall of
the washer (11) for the hanging bracket can be
prevented if the washing fixing plate (9) is used.
