Disconnect a Depleted Gas Cylinder
1. Close the regulator shut-off valve and gas cylinder shut-off valve by turning the knobs clock-
wise.
2. Disconnect the gas line from the regulator. Gas will be vented from the line. It is not necessary
to disconnect the gas line from the analyzer inlet if the cylinder will be replaced immediately
with one of the same type.
3. Open the gas regulator shut-off valve by turning the knob counter-clockwise. Gas will be ven-
ted from the regulator.
4. Turn the regulator control knob clockwise to open and vent any remaining gas. Both gauges
should read at or near zero. If not, make sure the gas regulator shut-off valve is open.
5. Close the regulator by turning the control knob counter-clockwise.
6. Use an appropriate wrench to loosen the nut at the regulator connector nut then remove the
regulator from the cylinder.
7. Replace the protective cap on the depleted cylinder. Disconnect the retaining strap and move
the cylinder to an appropriate location.
