(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.

(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).

(4) Manifold is isolated by insulating material that can bear 120
℃
or higher temperature.
Manifold attached foam can not be taken as insulating material.

(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:
