Manual Manifold
The manual manifold can be used as either main
supply or emergency reserve manifold (ERM). When
used as a emergency backup manifold the line
pressure regulator should be set slightly lower than
the primary supply pressure . This will prevent it
from feeding to the pipeline during normal operation
of the primary system. The line pressure regulator
can be increased to nominal distribution pressure in
the event of emergency.
