2-4. INSTALLATION
2-4-1. Outdoor unit installation location
For best performance, select proper position.
● Avoid places where combustible gas may be generated or leak.
● Avoid direct sunlight or other sources of heat.
● Install sunshade to protect the outdoor unit if direct sunlight hits the unit.
● Install the outdoor unit with enough distance between neighbours as operation noise may disturb the neighbours.
● Avoid the position that the unit is covered by snow or snow blows directly against the air outlet. The snow block or blow will
reduce the airflow of the outdoor unit.
In the areas of heavy snow, special countermeasures must be taken at installation to protect the outdoor unit from malfunc-
tion caused by snow.
● Select a location permitting easy wiring and pipe access to the power source and indoor unit.
● Drain water must be drained freely during operation. Check for draining.
2-4-2. Ventilation and service space
(1) Windy location installation
When installing the outdoor unit on a rooftop or other location unprotected from the wind, situate the air outlet of the unit so
that it is not directly exposed to strong winds. Strong wind entering the air outlet may impede the normal airflow and a mal-
function may result.
The following shows 3 examples of precautions against strong winds.
● Face the air outlet towards the nearest available wall about 50 cm away from the wall. (Fig. 2-1)
● Install an optional air guide if the unit is installed in a location where strong winds from a typhoon, etc. may directly enter
the air outlet. (Fig. 2-2)

● Position the unit so that the air outlet blows perpendicularly to the seasonal wind direction, if possible. (Fig. 2-3)
