About the connecting curvature of eld pipe and branch kit:
The eld pipe should be connected to the branch kit so that the curved angle on each side is
3 degree or less.
*[0 to 1 in. (0 to 26 mm)]
*[0 to 1 in. (0 to 26 mm)]
2ft. (0.5 m)

*: Allowed value based on "A" (center of eld pipe) at 2ft. (0.5 m) from "B"
(junction of the branch kit).
If the eld pipe is connected with angle larger than specied, the balance of split refrigerant
ow will be lost, and the refrigerant may concentrate upon specic outdoor unit as shown in
the following gure. Such unbalanced refrigerant ow may cause a compressor malfunction.
