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 wind-proofing 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.
Strong wind
4. When installing the unit in an area where snowfalls may be heavy, take steps to prevent the unit from being
adversely affected by the fallen or accumulated snow.
• Either make the foundation higher or install a stand (which is high enough to ensure that the unit will be
above the fallen or accumulated snow) and place the unit on it.
• Attach a snow shield (locally procured).
