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
first 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 first
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
Difference 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 difference is 110 m, (If the height
difference 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 difference is 110 m (If the height difference is over 50 m, need to decide
whether to install PDM kit or not.)
