(2) Manifold has serveral pipe sections with different pipe size, which facilitates to match
with various copper pipe. Use pipe cutter to cut in the middle of the pipe section with
different pipe size and deburr as well. See Fig. 4.3.3.
Fig. 4.3.3
(3) Y-type manifold can be installed vertically or horizontally. Confirm the position and then
weld the manifold pipe. See the Fig. 4.3.4(a). T-type manifold must be installed
horizontally with inclination, see the Fig. 4.3.4(b).

temperature. Manifold attached foam cannot be taken as insulating material.
4.3.3 Installation and thermal insulation for pipeline
(1) For multi VRF system, every copper pipe should be labeled so as to avoid
misconnection.
(2) Manifolds can be laid in the following ways:
The length of a straight pipe between two manifolds cannot be less than 500 mm
