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 filter. This filtered 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 compressed 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 filter, flow control valve, flowmeter, and finally exits the unit. The flow con­trol valve, which is part of the flowmeter, controls the amount of oxygen deliv­ered to the patient. The NewLife unit delivers up to 95.5% pure oxygen at flow
rates from 1–5 lpm.

NOTE: NewLife Elite OxiSilent™ option incorporates an additional felt intake
filter prior to air entering the compressor.

2.2 Operation Check

AirSep tests every NewLife Oxygen Concentrator thoroughly after manufacture.
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. Un-

pack 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 five

seconds to indicate that the battery for the alarm is good.
See the troubleshooting chart in Section 6.0 of this
manual if the unit’s alarm does anything other than
sound loudly for five seconds.

AirSep® Corporation

b. The compressor runs. Listen for the sound.
c. Exhaust air flows out of the bottom of the unit.

Elite Service Manual

3 Turn the flowmeter adjustment knob counterclockwise until it stops

(wide open).

The maximum flow should register 5.5 lpm (the 5.5 lpm line should
appear to split the middle of the flowmeter 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.

d. OPTIONAL: The Oxygen Monitor’s amber light remains

on until the oxygen concentration reaches 85% ± 3%
(approximately two minutes).

2.3.1 Battery Test

Each time the NewLife unit is turned on, a five-second audible alarm
sounds to indicate the condition of the battery.

NOTE

The audio alarm must sound loudly for approxi­mately five seconds each time the unit is turned to
ON to indicate the battery 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 Oxygen Concentration Test and Specification

To ensure that the unit’s output of oxygen is within specification, 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 humidifier 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 flow 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 humidifier bottle

(if used) and any other equipment/ accessories that may be re­quired.

6 Adjust the flowmeter adjustment knob to the prescribed level.

NOTE

Do not measure oxygen concentration output
after the product stream passes through a humidi­fier bottle, or erroneous readings will result.
