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.
Teams are required to check and/or adjust the relief valve to release air at 125 psi (~862 kPa, 7.9 Bar). The valve may or may not have been calibrated prior to being supplied to teams.
Instructions for adjusting the pressure relief valve can be found in the Pneumatics Manual.

downstream of the single primary regulator.
