R805       *If using pneumatics, these parts are required. If pneumatic COMPONENTS are used, the following items are required as part of the pneumatic circuit and must be used in accordance with this section, as illustrated in Figure 8‑14.

R802       *No custom pneumatics and meet minimum pressure ratings. All pneumatic items must be COTS pneumatic devices and either:

R811       *Relief valve requirements. The relief valve must be attached directly to the compressor or attached by legal hard fittings (e.g. brass, nylon, etc.) connected to the compressor output port.

R809       *Limited devices at high pressure. Only the compressor, relief valve, pressure switch, pressure vent plug, pressure gauge, storage tanks, tubing, pressure transducers, filters, and connecting fittings may be in the high-pressure pneumatic circuit upstream from the regulator.
