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 interference 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 wiringless remote controller kit is installed, the transmission 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 100·125: up to 4.0m).
•
However, if the ceiling height exceeds 2.7m (models 100·125: 3.2m), it is necessary to set on site from
the remote controller. Refer to the section “
10. FIELD SETTING
”.
(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, refer to the section “
10. FIELD SETTING
”.
(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 number 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.)
