NOTICE!
(1) Normally, the pipe length from the first branch of IDU to the farthest IDU is 40m (131-1/4ft.).
Under the following conditions, the length can reach 90m (295-1/4ft.).
1) Actual length of pipe in total: L1+L2x2+L3x2+L4x2+…+L9x2+a+b+…+i+j≤1000m
(3280-3/4ft.).
2) Length between each IDU and its nearest branch a, b, c, d, e, f, g, h, i, j≤40m (131-1/4ft.).
3) Difference between the pipe length from the first branch of IDU to the farthest IDU and the
pipe length from the first branch of IDU to the nearest IDU: L10-L11≤40m (131-1/4ft.).
(2) When the maximum length of the main pipe from ODU to the first branch of IDU is≥90m
(295-1/4ft.), then adjust the pipe size of the gas pipe and liquid pipe of main pipe according to
the following table.

If the length between an IDU and its nearest branch is above 10m (32-3/4feet), then double the size
of the liquid pipe of IDU (only for the pipe size that is≤6.35mm (1/4inch).
