4.4.3 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
(19-11/16in.). The length of a straight pipe before the main pipe port of the manifold cannot be
less than 500mm (19-11/16in.). The length of a straight pipe between the branch of the
manifold and the IDU cannot be less than 500mm(19-11/16in.). See Fig.4.4.5.
(3) There must be three fixing point for both horizontal and vertical installation of the
Y-type manifold. See Fig.4.4.6.
Fixing point 1: 100 mm on the main inlet manifold from the welding point
Fixing point 2: 200 mm on the main branched pipe from the welding point
Fixing point 3: 250 mm on the branched pipe from the welding point
