When installing the outdoor unit in a place that is constantly exposed to a
strong wind like a coast or on a high story of a building, secure a normal
fan operation by using a duct or a wind shield.
• Install the unit so that its discharge port faces to the wall of the
building.
Keep a distance 500mm(19-11/16inch) or more between the unit and
the wall surface.
• Supposing the wind direction during the operation season of the air
conditioner, install the unit so that the discharge port is set at right
angle to the wind direction.
