Actual Length
The distance between the outdoor unit and the farthest indoor unit ≤ 150m
Ex) 8 indoor units
a+b+c+d+e+f+g+p≤ 150m
Ex) 6 indoor units
a+b+c+d+j ≤ 150m
Equivalent
length
The distance between an outdoor unit and the farthest indoor unit ≤ 175m
Main pipe
length
The main pipe(a) from the outdoor unit to the first Y-joint should be less than
110m.
Total length
The sum of the total length of pipes should be less then 300m.

When the equivalent length between an outdoor unit and the farthest indoor unit exceeds 90m, upgrade the low
pressure pipe of the main pipe one step.
