Turning the Concentrator Off
•
MN137-1 rev. H
Optimal oxygen concentration is obtained within 10 minutes
after the device is switched on (90% of the concentration is
obtained after approximately 5 minutes).
It is very important to follow the prescribed level of oxygen flow.
Do not increase or decrease the flow until you first consult your
physician.
If oxygen does not seem to flow, first verify that the flowmeter
ball is registering a flow. Then, place the tip of the cannula into
a glass of water; if bubbles come out of the cannula, oxygen is
flowing. If bubbles do not appear, refer to Section 5.0.
Troubleshooting.
Ensure concentrator is operated in an upright position.
Set the I/0 power switch to the "0" position to turn off the unit.
