Pipe Length
Lay out pipes based on site requirements and the following principles:
● The length of a pipe should be as short as possible. The recommended length is
within 10 m. Avoid unnecessary turnings, lifting, and falling.
● Minimize the height
dierence between the indoor and outdoor units.
● Minimize the number of bends for pipes.
● The total length of the pipe connecting the indoor and outdoor units equals
the equivalent length of the straight pipe plus the length of the one-way
straight pipe connecting the indoor and outdoor units.

12.7 140 250 500
9.52 100 200 340

If the pipe between the indoor unit and outdoor unit is longer than 10 m, increase
the pipe diameter to reduce system resistance. The following table lists the
recommended pipe dimensions.
