PART ONE
INITIAL STARTUP OF THE CONCENTRATOR
NOTE: Concentrator may be used during the initial start warm-up time
(approximately 30 min.) while waiting for the O
2
purity to reach maximum.
When the unit is turned on, the green light will come on (SYSTEM OK / O
2
greater than
85%). After 5 minutes, the oxygen sensor will be operating
normally and will control the indicator lights depending on oxygen concentra-
tion values. The explanation of the indicator light functions are as follows.

OXYGEN PURITY INDICATOR
(IF YOUR UNIT FEATURES THE O
2
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.
NOTE: The use of some accessories such as the pediatric flowstand and the
Homefill II compressor will deactivate the Low Flow Alarm.
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 0.5L/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.
