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