Obstacles
[unit: in. (mm)]
Fig. 2
CAUTION
• Any vents, light xtures, or other appliances which may
disturb the airow might stain the ceiling if too close, so
follow Fig. 2 when installing.
Note)
1. This restriction applies to the exposed type lighting,
but does not apply to the recessed type, which does
not protrude below the ceiling line.
2. The clearance from the wall (indicated with *) must
be 20 in. (500 mm) or more if the air outlet is closed or
the horizontal blade is set to Airow block and, if the
corners (left and right corners of the target air outlet)
are also closed by 8 in. (200 mm) or more.
For how to set the airow direction (including Airow
block) with the horizontal blade, refer to Individual
AirowDirection in the operation manual attached
to the remote controller.
• Install the indoor and outdoor units, power supply wiring,
remote controller wiring and transmission wiring at least
3.3 ft. (1 m) away from televisions or radios to prevent im-
age interference or noise.
(Depending on the radio waves, a distance of 3.3 ft. (1 m)
may not be sufcient to eliminate the noise.)
• Install the indoor unit as far as possible from uorescent
lamps.
• Localized temperature difference from the room tempera-
ture, if too large, can affect how the infrared oor sensor
judges.
(This may occur, for example, in an area where oor
heating/high-temperature heat generating equipment is
installed.)
• Each sensor has been set so that the center of the sensing
area is located in the center of the product 32 in. (800 mm)
above the oor (in case of the infrared presence sensor)
or 0 in. (0 mm) above the oor (in case of the infrared oor
sensor) when the ceiling height is approximately 8-3/4 ft.
(2.7 m).
(2) Ceiling height
• This indoor unit can be installed in a space of which
ceiling height is up to 11-1/2 ft. (3.5 m) (Type 30 · 36 ·
42 · 48: 13-3/4 ft. (4.2 m))
•
However, if the ceiling height exceeds 8-3/4 ft. (2.7 m)
(Type 30 · 36 · 42 · 48: 10-1/2 ft. (3.2 m)), it is necessary
to set from the remote controller on site. Refer to the
section 10.FIELDSETTING.
(3) Direction of the air discharge
• Select the number of directions of the optimum air
discharge for the shape or the position of the room.
• The number of directions of the air discharge can be
changed by installing a sealing material.
• When installing a sealing material, the eld setting
from the remote controller is required. For details, refer
to the operation manual attached to the sealing materi-
als.
(It is set to the setting position number 01 (Standard ·
All round outlet) when shipped from the factory.)
• To use the optional sealing material kit to change the
setting of air discharge direction (4-way blow type (with
corners sealed)/3-way blow type), refer to the installa-
tion manual attached to it.

(4) Use suspension bolt for installation.
Investigate if the installation place can withstand the
mass of the indoor unit and, if necessary, hang the indoor
unit with bolts after it is reinforced by beams etc.
(Refer to the installation pattern paper (5) for the mount-
ing pitch.)
