- Move the gas cylinder close to the analyzer.
- Secure the cylinder in place using straps or chains connected to a wall bracket or other fixed surface, or use a cylinder stand.
- Use an appropriate cylinder wrench to remove the protective cap from the cylinder by turning the protective cap counterclockwise.
- Attach the gas regulator to the connector on the gas cylinder. Hand tighten the nut, then use an appropriate wrench to tighten an additional 3/4 turn.
- Check for leaks at the high pressure side of the regulator and in the connector.
- Turn the regulator control knob fully counterclockwise.
- Slowly open the gas cylinder shut-off valve, then close it.
- Observe the pressure on the high pressure gauge.
- If pressure drops, repair the leak.
- Connect the gas line to the regulator.
- Connect the gas line to the regulator connector.
- Use two 7/16 in. (11 mm) wrenches to tighten the gas line connection — one to hold the fitting steady and one to tighten the connector nut.
