Oxygen Concentrator
PN 14940837 B — 32
Flow Rate Test
1. Turn the power switch in the “ON” position.
2. Allow the concentrator to run continuously for a minimum
of 10 minutes.
3. Connect a flow meter to the outlet barb.
4. Turn the flow knob to the position of 0.5 LPM.
5. Verify that the flow displayed by the flow meter is within the
tolerances shown in table below.
6. Flow Rate must be +/- 10% or 200ml/min, whichever is
greater. See table below.
