(4) Manifold is isolated by insulating material that can bear 120ºC(248℉)or higher temperature.
Manifold attached foam cannot be taken as insulating material.
4.4.3 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 is 500mm (19-11/16inch) at least. And the
length of a straight pipe before main pipe port of the manifold cannot be less than 500mm (19-11/16inch).
The length of a straight pipe between the branch of the manifold and IDU cannot be less than 500mm
(19-11/16inch).
