Emptying a Cylinder
If the O

purity in the cylinder has dropped below 90%, the cylinder will need to be emptied.
To empty your O

cylinder, adjust your conserving device or regulator to the highest continuous flow setting and
wait for it to empty. After the cylinder has been emptied, it can be refilled again (Please see the section on Filling a
Cylinder).
