after branching of heade
r. 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 first 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
first branching section when the total capacity codes of all outdoor units are ov
er
26 (equivalent to HP).
