(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.37.
Unit: mm (in.)

(3) There must be three fixing point for both horizontal and vertical installation of the Y-type
manifold. See Fig.38.
Fixing point 1: 100mm (4in) on the main inlet manifold from the welding point
Fixing point 2: 200mm (7-7/8in.) on the main branched pipe from the welding point
Fixing point 3: 250mm (9-5/6in.) on the branched pipe from the welding point
Unit: mm (in.)
