Connecting the gas inlet for analyzers with Hauser’s
sample conditioning system (SCS)
1. Attach the Port Connector to the Hauser analyzer SCS
enclosure.
2. Connect the three-way valve to the port connector.
3. Connect the reducers to either side of the three-way valve.
4. Connect to the gas cylinder to the reducer on either side of the
three-way valve using 3 mm (1/8 in.) stainless steel tubing.
Purging the cylinder pressure regulators and analyzer
1. Install a pressure regulator to the nitrogen (N
2
) zero gas cylinder.
2. Install a pressure regulator to the O
2
calibration gas cylinder.
3. Purge the pressure regulator starting with the O
2
cylinder, then the
N
2
cylinder. Allow the gas to flow into the analyzer to purge also.
4. Close the pressure regulator outlet valve and open the cylinder
valve. This will pressurize the primary and secondary side of the
two-stage regulator.
5. Adjust the regulation pressure to 200 KPaG (30 PSIG).
Refer to Figure 4–40 for connection locations and the OXY5500
SCS Operating Instruction for more information on the sample
conditioning system.
