Classication Condition Example
First branch joint ~
Farthest Indoor unit
45m (148') ≤ b+c+d+e+f+g+p ≤ 90m (295'): 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)x2+h+i+j+k+l+m+n+p
≤ 1000m (3281')
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)x2+h+i+j+k+l+m+n+p ≤
1000m (3281')
Each Y-joint ~ Each
indoor unit
h, i, j, … p ≤ 45m (148')
Dierence between the distance of the outdoor unit to the farthest indoor
unit and nearest indoor unit ≤ 45m (148'), (a+b+c+d+e+f+g+p)-(a+h) ≤
45m (148')
Note 2) When indoor unit is located at higher level than outdoor unit, allowable height dierence is 110m(361’), (If the height
dierence is over 40m(131’), contact your local dealer for more information.) but when the indoor unit is located at
lower level than outdoor unit, allowable height dierence is 110m (361’) (If the height dierence is over 50m(164’),
need to decide whether to install PDM kit or not.)
