[Gages on Schematics
**************************************************************************
NOTE: Delete paragraphs if control schematics are
not shown on project drawings.
**************************************************************************
Certain pressure and temperature gages are designed on schematic flow
diagrams in the drawings. Where a monitor gage satisfies the required
location on a schematic, no additional gage needs to be furnished.]

Control Schematics
**************************************************************************
NOTE: Delete paragraphs if control schematics are
not shown on project drawings.
**************************************************************************
The drawings show a generalized overall control system for compressor,
auxiliaries, remote panel transmitting and receiving, and remote panel. The
system is shown using relay symbology. Contractor and equipment suppliers
may use standard panel features to accomplish the total requirements using
other methods of signal, solid state devices, or revised lamping. All
wiring diagrams and required devices shall be approved by the Contracting
Officer prior to installation.
]2.3.6
Control Air Supply
**************************************************************************
NOTE: Revise paragraph and make provisions for
control air if there is no existing air supply.
Specify quantity of control air and maximum dew
point.
**************************************************************************
[Extend existing] [Provide new] control air system of dry and purified air
for the compressor controls. Sizing shall be based on not less than [_____]
[425 L/s] [15 SCFM]. Filtration shall be to 5 micrometers minimum and the
