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.
