d. OPTIONAL: The Oxygen Monitor’s amber light
remains on until the oxygen concentration reaches 85%
± 3% (approximately two minutes).
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.
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 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.
