2.7.3 Setting the Pressure
Note:
Perform these steps only after the entire system has been plumbed, including the Aurora H2O .
1. Ensure the inlet sample gas isolation valve on the Aurora H2O sample system is closed. Open the isolation ball
valve at the Optional Pipeline Insertion Membrane Liquid Separator/Pressure Regulator .
2. Turn the pressure adjustment screw clockwise to increase the pressure (see Figure 23 below). The optional
pipeline insertion membrane liquid separator/pressure regulator is the FIRST STAGE pressure reduction of the
system when used. Depending upon your source pressure, you should step down the pressure to a value in the
range listed in Table 2 below.
3. Tighten the lock nut down to the top of the pressure regulator to avoid future possible changes in pressure
regulator setting, once the pressure is set.
