2) Length between each IDU and its nearest branch a, b, c, d, e, f, g, h, i, j
≤
40m(131-1/4feet).
3) Difference between the pipe length from the first branch of IDU to the farthest IDU and the pipe
length from the first branch of IDU to the nearest IDU: L10-L11
≤
40m(131-1/4feet).
(2) When the outdoor unit is at upper side and height difference is more than 50m, please consult
company for the related technical requirement.
(3) When the maximum length of the main pipe from ODU to the first branch of IDU is
≥
90m(295-
1/4feet), then adjust the pipe size of the gas pipe and liquid pipe of main pipe according to the
following table.
