Indoor Unit Dimensions
This section provides dimensional data for the indoor unit. The unit is designed for ceiling mounting and has a square cassette form factor. Key dimensions include the main body width and depth of 32-5/8 inches (830mm) and a height of 9.65 inches (245mm). The front panel extends to approximately 37-1/2 inches (950mm) square. It also details the drain hole size (1 inch / ø25mm) and indicates the locations for liquid and gas line connections.
Indoor Unit Installation Instructions
This section illustrates the recommended installation clearances for the indoor unit within a ceiling space. It depicts the unit suspended from the ceiling, with considerations for ventilation and illumination. Crucially, it specifies minimum clearances: 59.1 inches (150cm) from the ceiling to the unit, with 78.7 inches (200cm) recommended for optimal performance. Further clearance of 157.5 inches (400cm) is shown for ventilation. A table provides model-specific data for the distance from the ceiling (Length of A), required overhead clearance (Length of H), and the ceiling opening size (Length of B).
| MODEL | Length of A | Length of H | Length of B |
| 9K/12K/18K | 9.6in (245mm) | >10.8in (275mm) | 23.6in (600mm) |
| 24K | 8.03in (205mm) | 9.06in (230mm) | 35.4in (900mm) |
| 36K | 9.65in (245mm) | 10.7in (271mm) | |
| 48K | 11.3in (287mm) | 12.3in (313mm) |
Outdoor Unit Dimensions and Installation
This section details the physical dimensions and required installation clearances for the outdoor unit. The unit is rectangular. Key dimensions are approximately 38-1/2 inches (980mm) in width, 16-3/8 inches (415mm) in depth, and 38-3/8 inches (975mm) in height. Installation requires significant clearance around the unit for proper airflow and maintenance: 20 inches (500mm) or more is needed at the front and sides if two adjacent sides are clear, and 4 inches (100mm) or more is required on other sides, with 14 inches (350mm) specified for the rear. The document emphasizes meeting all spatial requirements.
