Installation Manual
• In the case of the installation of a wireless remote controller,
the transmission distance of the wireless remote controller may
be shortened if the room has a fluorescent light of electronic
lighting type (i.e., an inverter or rapid-start fluorescent light).
Keep the distance between the receiver and the fluorescent
light as far as possible.
(2) Use hanging bolts to install the indoor unit. Check that the
place of installation withstands the weight of the indoor unit.
Secure the hanging bolts with proper beams if necessar y.

• The H1 dimension indicates the
height of the product.
• Determine the H2 dimension by
maintaining a downward slope of
at least 1/100 as specified in
"7. DRAIN PIPING WORK".
4. PREPARATIONS BEFORE INSTALLATION
(1) Check the positional relationship between the ceiling open-
ing hole and the hanging bolt of the unit.
• For the maintenance, inspection, and other servicing
purposes of the control box and drain pump, prepare one
of the following service spaces.
1. Inspection hatch 1 (450 × 450) for the control box and
a minimum space of 300 mm for the lower part of the
product. (Refer to Fig. 2-2)
2. Inspection hatch 1 (450 × 450) for the control box and
inspection hatch 2 for the lower part of the product
(see axial direction view A-1). (Refer to Fig. 2-3)
3. Inspection hatch 3 for the lower part of the product
and the lower part of the control box (see axial direc-
tion view A-2). (Refer to Fig. 2-3)

(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 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 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 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 founda-
tion bolts so that they will withstand the weight of the unit.
Adjust the distance to the ceiling surface in advance.
