d.) Observe the high pressure gauge. If the pressure decreases, tighten the nut connecting the
regulator to the gas bottle. If the pressure is stable, proceed to step e.
e.) Turn the pressure regulator control knob clockwise until the low pressure gauge indicates 15
psig (100 kPag). Open each regulator shut-off valve by turning it counterclockwise. Open the
gas bottle shut-off valve. Flow gas for 10 to 30 seconds, then close each valve. These actions
purge the regulator and gas inlet tubing.
f.) Ensure that the gas shut-off bottle valve is completely closed (turn clockwise).
5. Repeat steps 1 through 4 for each gas supply bottle to be attached to the analyzer.

Connecting the Gas Delivery Tubing to the Analyzer
The gas inlet ports are located on the right side panel of the analyzer. The ports are labeled 1 through 6.
To change the gas attached to one of the ports:
1. Make sure the port valve is closed (refer to Enable Manual Control, page 6-20).
2. Detach the gas line from the desired port.
3. Attach the new gas line to the port.
4. Make sure any unused gas inlet ports are plugged.
5. Record the gas installed in the port in the analysis program as described in the following section.
If you are using hazardous gases, make sure the gas supply
equipment is adequately vented to prevent purging the regulator
and tubing into the lab atmosphere in the following step.
