(*1):(D) is outdoor unit furthest from the 1st branch and (j) is the indoor unit furthest from the 1st branch.
(*2) :If the height difference (H1) between indoor and outdoor unit exceeds 3 m, set 65 m or less.
(*3) :If the max. combined outdoor unit capacity is 54HP or more, then max. equivalent length is 70 m or less (real length is 50 m or less).
(*4) :If the height difference (H2) between indoor units exceeds 3 m, set 50 m or less.
