Turning the Concentrator On
Press power switch to the

position. The display will read
“HELLO”. At that
time, the green, yellow, and red lights will turn on simultaneously indicating the
machine is functioning as expected. After about 1 second, only the green light
will remain on. After 4 seconds, the display will show the runtime.
To properly read the flow meter, locate the prescribed flow rate line on the flow
meter. Next, turn the flow knob until the ball rises to the line. Now, center the
ball on the L/min line as prescribed (Figure 3).
NOTE:
Oxygenation times and the flow rate ranges are established and
prescribed by your physician.

CAUTION:
If the flow rate on the flow meter ever falls below 0.5L/min, check the
tubing for blockage or kinks and check for a defective humidifier bottle.
