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.).
a)
Actual length of pipe in total: L1+L2x2+L3x2+L4x2+…+L10x2+A11+A12+…+D21+D22
≤1000m (3280-3/4ft.).
b) Length between each IDU and its nearest branch A11, A12, B21, B22, D21,
D22≤40m(131-1/4ft.).
c) 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: L12-
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.
Outdoor Model
Size of connection between outdoor unit and the first indoor branch
Low pressure gas pipe mm(in.) Liquid pipe mm(in.) High pressure gas pipe mm(in.)
