Caution (Multi type)
When there is a branch which is not used, install less than 1 branch per one set of Multi
type, and less than 2 branches per 1 refrigerant system.
However, be sure to connect indoor unit about the furthest branch from outdoor unit side.
Only "Multi type RB unit" is connectable with the side opposite to piping connected the
outdoor unit side and maximum connectable number is "two".
In case of two RB units connected in series ( total 8-branches ), maximum capacity of
connectable indoor units is up to 191,000 Btu/h.
