CAUTION
1. Install the outdoor unit in a location where the discharge air is not
blocked.
2. When an outdoor unit is installed in a location that is always exposed
to strong winds like a coast or on the high stories of a building, secure
normal fan operation by using a duct or wind shield.
3. When installing the outdoor unit in a location that is constantly
exposed to strong winds such as on the upper stairs or rooftop of a
building, apply the windproofi ng measures referred to in the following
examples.
1) Install the unit so that its discharge port faces the wall of the
building.
Keep a distance 500 mm or more between the unit and wall
surface.
2) Consider the wind direction during the operational season of the air
conditioner, and install the unit so that the discharge port is set at a
right angle relative to the wind direction.
