Remarks
Same to connecting pipe
size of outdoor unit
Pipe size differs based on
total capacity code value of
outdoor units at
downstream side.
(See Table 2.)
Pipe size differs based on
capacity code of outdoor
unit.
(See Table 2.)
Pipe size differs based on
total capacity code value of
indoor units at downstream
side.
If the total value exceeds
the capacity code of the
outdoor unit, apply capacity
code of the outdoor unit.
(See Table 1.2.)
∗
1: If exceeding the main pipe size, decide the size same to
main pipe size.
