The unit can be installed in room A at the
specified installation height, and without
further room size or ventilation requirements.
Unit can be installed in room A if you provide 2 openings (one at the bottom, one at the top) between room A and B to ensure natural ventilation. The openings

INFORMATION
Multiple indoor units. If two or more indoor units are installed in a room, you must
consider the maximum refrigerant charge that can be released in the room when a
SINGLE leak occurs. Example: If two indoor units are installed in the room, each with
its own outdoor unit, then you have to consider the refrigerant charge of the largest
indoor-outdoor combination.
