6.4 Connection of Branch Pipe
1) If two or three BU modules used, Y-type branch pipe of FQ01A/A will be chosen.
FQ01A/A (Liquid pipe) FQ01A/A (Gas pipe)
2) Y-type branch pipe is equipped with auxiliary tubes to adjust the diameter of different pipes. If the
dimension of the pipe selected is different from the dimension of branch pipe joint, Cut the copper tube
in the middle with tube cutter and clear up burrs. Plea se do that as following figure.
3) Y-type branch pipe must be installed in vertical or horizontal direction. In the inlet of the branch pipe,
keep at least 500mm straight pipe.
