1) Y-type manifold, see in Fig.3.4.2.
2) Manifold has several pipe sections with different pipe size, which facilitates to match with
various copper pipes. Use pipe cutter to cut in the middle of the pipe section with different
pipe size. See the Fig. 3.4.3 as below.
3) Y-type manifold can be installed vertically or horizontally. Confirm the position and then
weld the manifold pipe. See Fig.3.4.4.
4) The length of a straight pipe between two manifolds cannot be less than 500 mm.
5) The length of a straight pipe before the main pipe port of the manifold cannot be less than
500 mm.
6) The length of a straight pipe between the branch of the manifold and the IDU cannot be
less than 500 mm.
