Connecting a Gas Bottle
Move the gas bottle close to the instrument and tether it into place.
1. Use an appropriate cylinder wrench to remove the protective cap from the bottle.
2.
Attach the gas regulator to the connector on the gas bottle. Hand-tighten the nut, then use
an appropriate wrench to tighten an additional 3/4 turn.
3.
Check for leaks at the high-pressure side of the regulator and in the connector.
a. Turn the regulator control knob fully counterclockwise.
b. Slowly open the gas bottle shut-off valve, then close it.
c. Observe the pressure on the high-pressure gauge.
If the pressure is stable, proceed with the next step.
If the pressure decreases, tighten the regulator connector nut until it becomes stable.
Do not overighten the fitting; doing so may cause a leak.
