*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.
Ú For HR model, only increase the size of the liquid pipe If pipe length exceeds 90m
Ú 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.
