OPERATING INSTRUCTIONS WARNING DO NOT change the L/min. setting on the flowmeter unless a change has been prescribed by your physician or therapist. NOTE: To properly read the flowmeter, locate the prescribed flowrate line on the flowmeter. Next, turn the flow knob until the ball rises to the line. Now, center the ball on the L/min. line prescribed (FIGURE 7). 2. If the flowrate on the flowmeter ever falls below 0.5 L/min. for more than about one minute, the LOW FLOW ALARM will be triggered. This is a rapid beeping of the audible alarm. Check your tubing or accessories for blocked or kinked tubing or a defective humidifier bottle. After rated flow is restored, more than 0.5 L/min., the Low Flow audible alarm will go off.

SENSO2 OXYGEN PURITY INDICATOR (IF YOUR UNIT FEATURES THE O2 SENSOR FEATURE) This feature monitors the purity of oxygen generated by the oxygen concentrator. If purity falls below factory preset standards, indicator lights on the control panel will illuminate. INITIAL STARTUP OF THE CONCENTRATOR NOTE: Concentrator may be used during the initial start warm-up time (approximately 30 min.) while waiting for the O2 purity to reach maximum. When the unit is turned on, the green light will come on (SYSTEM OK/O2 greater than 85%). After 5 minutes, the oxygen sensor will be operating normally and will control the indicator lights depending on oxygen concentration values. The explanation of the indicator light functions are as follows. 17
