Figure 2: Humidifier Features
DO NOT add water over the maximum water level. Add purified water to the
humidifier bottle between maximum and minimum water level indicated.
Power switch:
|
indicates the power is on,
O
indicates the power is off. If the
switch is set to
“ON” when a power outage occurs, the oxygen concentrator will
not run, and an audible alarm will sound.
The oxygen will pass through the humidifier. Purified water should be added to
the humidifier between maximum and minimum water level as indicated. If the
oxygen tube exiting the humidifier is dislodged or jammed, the pressure in the
humidifier will increase to 25±5kPa and the safety valve of humidifier will open
to release the pressure.
To verify that this safety feature of the humidifier is working:
1.
Use the soft PVC tube to connect the humidifier bottle to the oxygen outlet of
the device.
2.
Turn on the oxygen concentrator and adjust the flow rate to about 5L/min.
3.
Block the exit point of the humidifier.
4.
After about 5 seconds, the safety valve will open, the gas will release, and the
valve will close. This indicates that the safety valve of the humidifier is
working as expected.
