The Daikin Oterra Series described here is primarily designed for cooling. If you require heating capabilities, please check the specific model number on the packaging to confirm if it includes heat pump functionality.

For optimal performance, mount the indoor unit on an interior wall with plenty of clearance around the top and sides to allow for proper air circulation. Avoid placing it directly above heat sources or in areas where furniture might obstruct the airflow path.
