*Maximum pipe length : The pipe length between an outdoor unit and the farthest indoor
unit.
Note1) If Ø 25.40 pipe is not available on site, use Ø 28.58 pipe.
Note2) If Ø 31.75 pipe is not available on site, use Ø 34.92 pipe.
Note3) If Ø 38.10 pipe is not available on site, use Ø 41.28 pipe.
※ For the case that the diameter of the default pipe of an outdoor unit does not match that of
the pipe installed on the site, a socket is provided by default together with the outdoor unit.
Size of the pipe between branch joints (B)
Select the pipe size according to the sum of indoor unit capacity which will be connected after
the branch.
※ However, if the size of the pipe between branch joints (B) is bigger than the size of the pipe
connected to the outdoor unit (A), apply the pipe size (A).
