2.3.1. 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
malfunction may result.
The following shows three examples of precautions against strong winds.
1 Face the air outlet towards the nearest available wall about 35 cm away from the
wall. (Fig. 2-3)
2 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. 2-4)

3 Position the unit so that the air outlet blows perpendicularly to the seasonal wind
direction, if possible. (Fig. 2-5)
