(5) Fixing of manifolds. 
There must be three fixing point for both horizontal and vertical installation of the Y-type manifold. 
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.) 
 
Branches of a manifold must be laid parallel and cannot be wrapped in superimposed mode. 
(6) T-type manifold can be laid in the following ways: 
1) T-type manifold must be installed horizontally with inclination.
