2.5. Ventilation and service space
Note:
The dimensions given along the arrows above are required to guarantee the
air conditioner's performance. Install the unit in as wide a place as possible
for later service or repairs.
2.5.1. 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 3 examples of precautions against strong winds.
Face the air outlet towards the nearest available wall about 20" (500 mm) away
from the wall. (Fig. 2-2)
Install an optional wind baffle if the unit is installed in a location where strong
winds from a typhoon, etc. may directly enter the air outlet. (Fig. 2-3)
Wind baffle
Position the unit so that the air outlet blows perpendicularly to the seasonal wind
direction, if possible. (Fig. 2-4)
