*2: Up to a total of 6.0 maximum equivalent to HP capacity codes is connectable to one
line after branching of header. When the total capacity codes of all outdoor units are 12
to below 26 (equivalent to HP) and you use a branching header for the ?rst branching
section, use a RBM-HY2043E or RBM-HY2083E regardless of the total capacity codes
of outdoor units at downstream side. In addition, you cannot use a branching header for
the ?rst branching section when the total capacity codes of all outdoor units are over 26
(equivalent to HP).
