2.0 Operation Check and Oxygen Concentration Test
2.1 Description of Operation
Air enters the NewLife Oxygen Concentrator through an external air intake
gross particulate lter. This ltered air enters the compressor via a suction
resonator, which quiets the compressor’s suction sound. Pressurized air then
exits the compressor and passes through a heat exchanger. The heat exchanger
reduces the temperature of the com pressed air. Next, a two-way solenoid
feed valve directs the air into one of two sieve beds that contain molecular
sieve. The unique property of molecular sieve enables it to physically attract
(adsorb) nitrogen when air passes through this material, thus producing high
concentration oxygen.
There are two sieve beds: while one produces high concentration oxygen, the
other is purged of the nitrogen it adsorbed (collected) while it made oxygen.
Each adsorber produces oxygen for approximately eight seconds and delivers it
to the product tank. Oxygen exits the product tank through a pressure regulator,
product lter, ow control valve, owmeter, and nally exits the unit. The ow
control valve, which is part of the owmeter, controls the amount of oxygen
delivered to the patient. The NewLife unit delivers up to 95.5% pure oxygen at
ow rates from 1–5 lpm.
NOTE: NewLife Elite OxiSilent™ option incorporates an additional felt intake
lter prior to air entering the compressor.
2.2 Operation Check
AirSep tests every NewLife Oxygen Concentrator thoroughly after manufac-
ture. You must perform the following test to ensure that no damage occurred
in shipping or handling.
1 Open and inspect all cartons (that contain units) upon delivery. Unpack
the unit and remove it from the carton. Inspect the unit itself for
damage. If the exterior of a unit’s carton is damaged, or the unit itself
is damaged, note it on the freight bill signed by the driver.
2 Plug in the power cord of the unit, and set the ON/OFF switch to the
ON position. Check to see that the following occurs:
a. A continuous alarm loudly sounds for approximately
ve seconds to indicate that the battery for the alarm
is good. See the trou bleshooting chart in Section 6.0 of
this manual if the unit’s alarm does anything other than
sound loudly for ve seconds.
AirSep® Corporation
b. The compressor runs. Listen for the sound.
c. Exhaust air ows out of the bottom of the unit.

Elite Service Manual
d. OPTIONAL: The Oxygen Monitor’s amber light
remains on until the oxygen concentration reaches 85%
± 3% (approximately two minutes).
3 Turn the owmeter adjustment knob counterclockwise until it stops
(wide open).
The maximum ow should register 5.5 lpm (the 5.5 lpm line should
appear to split the middle of the owmeter ball) with no connections
at the oxygen outlet. If not, refer to Section 5.8.1 to set the product
regulator.
4 Perform an oxygen concentration test, as described in Section 2.4.
2.3 Alarm System
The NewLife Oxygen Concentrator is equipped with a battery-powered alarm
system, which sounds a continuous and loud alarm when a power failure
occurs. It sounds an intermittent alarm if the high or low pressure indicators
are activated or if the optional oxygen monitor detects lower than therapeutic
levels of oxygen concentration. The alarm remains on until you correct the alarm
condition or you set the ON/OFF switch to the OFF position. Refer to Section
6.0 for a list of probable alarm causes.
2.3.1 Battery Test
Each time the NewLife unit is turned on, a ve-second audible alarm
sounds to indicate the condition of the battery.
NOTE
The audio alarm must sound loudly for
approximately ve seconds each time the unit is
turned to ON to indicate the bat tery is in good
condition.
2.3.2 Power Failure Alarm Test
To test the power failure alarm, take the following step:
Unplug the unit, and set the ON/ OFF switch to the ON
position.
This should immediately activate the audio alarm. If it does not, refer
to the troubleshooting chart in Section 6.0 of this manual.

2.4 OxygenConcentrationTestandSpecication
To ensure that the unit’s output of oxygen is within specication, you
must perform a test of oxygen concentration. Test the unit upon delivery
to a patient and at periodic intervals. Equipment Providers, based on
their expertise and documentation, may establish and implement their
own protocol to check oxygen concentration. The interval established
may be longer or shorter than 90 days, which is AirSep’s default time
period for providers who do not choose to establish their own protocol.
1 If an oxygen humidier bottle is used, remove it from the oxygen
outlet.
2 Connect a calibrated oxygen concentration analyzer to the oxygen
outlet.
3 Verify that the product ow rate delivered by the unit matches the
patient’s prescription and does not exceed the capacity of the unit.
4 Set the unit’s ON/OFF power switch to the ON position. (It takes
approximately five minutes for the oxygen concentration to
stabilize.) Take oxygen concentration readings every 60 seconds
until the analyzer shows that two consecutive readings are the
same.
5 Disconnect the oxygen analyzer, and reconnect the humidier
bottle (if used) and any other equipment/ accessories that may be
required.
6 Adjust the owmeter adjustment knob to the prescribed level.
NOTE
Do not measure oxygen concentration output
after the product stream passes through a
humidier bottle, or erroneous readings will
result.
