Classication Condition Example
First branch joint ~
Farthest Indoor unit
45 m ≤ b+c+d+e+f+g+p ≤ 90 m: 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 ≤ 45 m, (a+b+c+d+e+f+g+p)-(a+h) ≤ 45 m
Note 2) When indoor unit is located at higher level than outdoor unit, allowable height dierence is 110 m, (If the height
dierence is over 40 m, 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 110 m (If the height dierence is over 50 m, need to decide
whether to install PDM kit or not.)
