Classication Condition Example
First branch joint ~
Farthest Indoor unit
45m ≤ b+c+d+e+f+g+p ≤ 90m: branch pipes
(b, c, d, e, f, g) size must be increased by 1 grade
Total length of
extended pipe
If the size of pipe (main pipe), between the
rst branch joint and the outdoor unit, is not
increased by 1 grade, a+(b+c+d+e+f+g)×2
+h+i+j+k+l+m+n+p ≤ 1000 m
If the size of pipe (main pipe), between the
rst branch joint and the outdoor unit, is
increased by 1 grade, (a+b+c+d+e+f+g)×2
+h+i+j+k+l+m+n+p ≤ 1000 m
Each Y-joint ~
Each indoor unit
h, i, j, … p ≤ 45 m
Dierence between the distance of the outdoor unit to the farthest indoor unit
and nearest indoor unit ≤ 45m, (a+b+c+d+e+g+p)-(a+h) ≤ 45m
Note 2) When indoor unit is located at higher level than outdoor unit, allowable height dierence is 110m, (If the
height dierence is over 40m, contact your local dealer for more information.)
but when the indoor unit is located at lower level than outdoor unit, allowable height dierence is 110m (If the
height dierence is over 50m, need to decide whether to install PDM kit or not.)
