CAUTION
• Install the indoor and outdoor units, power supply wiring,
remote controller wiring and transmission wiring at least 1
meter away from televisions or radios to prevent image inter-
ference or noise.
(Depending on the radio waves, a distance of 1 meter may
not be sufficient to eliminate the noise.)
• Install the indoor unit as far as possible from fluorescent
lamps.
If a wireless remote controller kit is installed, the transmis-
sion distance may be shorter in a room where an electronic
lighting type (inverter or rapid start type) fluorescent lamp
is installed. (NOTE 1)
NOTE
1. Restriction applies to the exposed type lighting but does not
apply to the recessed type.
2. When the air outlet is closed, the space shown with " "
must have a distance of 30mm or more.
3. For setting the airflow direction of horizontal blade, refer to
the operation manual attached to the indoor unit and
remote controller.
(2) Ceiling height
• This indoor unit can be hung from the ceiling of which
height is up to 3.5m (models 100: up to 4.0m).
• However, if the ceiling height exceeds 2.7m (models 100:
3.2m), it is necessary to set on site from the remote con-
troller. Refer to the section "10. FIELD SETTING AND
TEST OPERATION".
(3) Air discharge direction
Select the air discharge pattern according to the installation
location.
In case of 2-way and 3-way, it is required to set on site from
the remote controller.
For details, see the section "10. FIELD SETTING AND
TEST OPERATION".
(Caution) Since there are some restriction on the piping
connection side, make sure to select the air dis-
charge pattern from the Fig. 3.
The names of air outlet are shown in inscription by the num-
ber of "
" marks on the underside of the air outlet.
(Refer to the Fig. 4)
(4) Use hanging bolts for installation.
Investigate if the installation place can withstand the mass
of the indoor unit and, if necessary, hang the unit with bolts
after it is reinforced by beams etc.
(Refer to the installation pattern paper (11) for the mounting
pitch.)
