5.6 Branch Joints
Notes for installers
 Use U-shaped branch joints as specified on the
construction drawings – do not replace U-shaped branch
joints with tee joints.
 To avoid accumulation of oil in the outdoor units, outdoor
branch joints should be installed horizontally and must not
be higher than the outdoor unit refrigerant outlets. Refer
to Figure 3-5.9.
 Indoor branch joints may be installed either horizontally or
vertically. Horizontal branch joints must be installed at an
angle to the horizontal not exceeding 10° in order to avoid
uneven distribution
malfunction. Refer to Figure 3-5.8.

 To ensure even distribution of refrigerant, a limitation is placed on how close branch joints may be installed to
bends, other branch joints and the straight sections of piping leading to indoor units. Refer to Part 3, 0 "Branch
Joints".
