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

•
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
