3. Select an installation location as follows:
•
Minimum Space
•
Down slope gradient for condensate piping: 1/25 to 1/100
Install the indoor unit at least 10.2 ft (3.1m) above
floor level.
4. Consider the air distribution from the indoor unit to the space of the room, and select a suitable location
so that uniform air temperature in the room can be obtained.
5. Install the unit where there are no obstacles which can impede the return air and discharged air.
6. Do not install the unit near a door or a window where the indoor unit comes into contact with humid
outside air. Otherwise, condensation may occur.
7. In the event that temperature and humidity levels inside the ceiling exceed 86
o
F (30
o
C)/RH, relative
humidity 80%, apply additional insulation materials to the external surface of the indoor unit to avoid
condensation.
8. If installing the indoor unit to a high ceiling, the warmed air will remain near the ceiling during heating
operation. Thus, a parallel installation of a circulator is recommended.
9. Do not install the indoor unit where airflow from the air outlet blows directly onto temperature detection
devices such an alarm device or a control device. It can result in false readings and an alarm failure.
10. When installing the IR receiver kit (optional) or the motion sensor (optional), refer to their respective
installation manuals.
11. The ceiling height of the indoor units can be increased when using High Speed Setting.
Refer to Section 8.7 "High Speed Setting".
NOTE:
There must be sufficient structural integrity to support
the weight of the unit. The designated ceiling surface
area should allow for additional space for the optional
decorative panel installation. Do not install against any
sloped ceiling areas as the tilted axis will interfere with
the proper flow and disposal of moisture.
