APPENDIX B MANIFOLDS Two sets of manifolds are available as an optional extra. Each set comprises a separate hot and cold water manifold. Both are provided with a 22mm inlet connection t t i t i l located centrally. All outlet connections are 15mm compression.
Page 27 APPENDIX B The pressure loss through a ﬂow regulator at the designated ﬂow rate is about 1.8 bar. Therefore for the ﬂow regulator to control the ﬂow rate at pre-set level,the inlet pressure must be greater than 1.8 bar. If the inlet pressure is lower,the ﬂow rate will be correspondingly less than the pre-set values.
Page 28 APPENDIX B The size of the distribution pipes supplying the manifold should be calculated using the method set out in BS 6700. A typical diagrammatic arrangement of a system using Manifold Type 1 is shown below. This is only meant to show the principles involved and the actual connection of ﬁttings to the manifold will need to suit the arrangements shown on page 35.
