Note1) If Ø 25.40 pipe is not available on site, use Ø 28.58 pipe.
࢜
For HR model, only increase the size of the liquid pipe If pipe length exceeds 90m
࢜
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.
