4.6 Pipework Layout
A correct pipework installation is essential
for trouble-free coil operation. Figure 16
gives an example for piping water coils.
(The diagram does not limit the type of
control system used.)
All pipework must be supported
independently from the coils.
All connections must be made in such a
way that the expansion and contraction of
pipes do not impose forces on the coil
headers. Failure to do so may result in
coil damage.
