4. Installation & Operation
DO NOT add water above the maximum water level. Pure water shall be added in humidier between the
maximum and minimum water level in use.
•Power switch ——I indicates that the power is on. O indicate the power is off.
•If power is lost while the oxygen concentrator is on it will not run and the alarm will sound.
•The oxygen is obtained by passing through the humidier. Pure water should be added to the humidier.
When the tube of oxygen exits the humidier, the pressure in the humidier will ascend to 25±5kPa and
the safety valve of the humidier will open to release the pressure.
Inspection of humidier performance:
1. Use the PVC soft tube to connect the humidier adapter to the oxygen outlet
2. Turn on the oxygen concentrator and adjust the ux to about 5L/ min. Jam the exit of humidier and after
about 5 seconds the safety valve will open and the gas will release and the valve will close, which indicates
that the gas proong of the humidier and safety valve is conforming.
4.2 Preparation
•Unscrew the cover of the humidifier. Fill the humidifier bottle between the maximum and minimum water
level lines with purified water (or distilled water). Screw the cover onto the humidifier bottle. (If needed,
add medication now to the water according to the physicians’s recommendations.)
•Screw the humidifier bottle absorption connector onto the cover of the humidifier, and insert the
humidifier to the elastic belt located on the left side of the unit. Connect the other end of the cannula to
the oxygen outlet.
•Plug in power supply. Ensure that the power switch is off. Plug the concentrator’s AC connector into the
power outlet.
4.3 Starting up the Concentrator
•Press the power switch to the“|”position. A green and yellow light will be displayed. This indicates that the
function of the device is normal. After about 1 second only the green light will remain on. After 4 seconds
the display screen of elapsed time meter shows total elapsed working hours.
•To properly read the flow meter locate the prescribed flow rate line on the flow meter. Next, turn the flow
knob until the ball rises to the line. Lastly, center the ball on the L/min. line as prescribed (Figure 3).
NOTE: Oxygenation times and ow rate ranges are established and prescribed by your physician.

4.4 Alarm Signal
•Initial Startup of the Concentrator
NOTE: Concentrator may be used during the initial start warm-up time (approximately 30 minutes), while
waiting for the O2 concentration to reach maximum.
When the unit is turned on the green light will appear (O2 concentration greater than 82%±3%). After 5
minutes, the oxygen sensor will operate normally and will control the indicator lights depending on the
oxygen concentration values.
4.5 Alarm Signal cue
1. O2 concentration is greater than 85%±2%. Green light illuminates. Normal Operation.
2. O2 concentration is greater than 73%± 2% and less than 85%±2%. Yellow light illuminates.
3. O2 concentration is less than 73%±2%. Red light illuminates and intermittent audible alarm sounds.
4.6 Turning the Concentrator Off
Press the power switch to the “ O ” position and unplug the concentrator’s AC connector from the power
outlet. Use the plug device to isolate the concentrator from the supply mains.

Due to the fact that the EUT
contains no components
susceptible to magnetic
eld, it is deemed to fulll
the relevant immunity
requirement without
testing.
Power frequency magnetic
elds should be at levels
characteristic of a typical
location in a typical
commercial or hospital
environment.
Note: UT is the a.c. main voltage prior to application of the test level.

Portable and mobile RF communications
equipment should be used no closer to any part
of the Medacure Oxygen Concentrator, including
cables, or more than the recommended separation
distance calculated from the equation applicable to
the frequency of the transmitter.
Recommended separation distance:
d= 1.2 √P
d= 1.2 √P 80 MHz to 800MHz
d= 2.3 √P 800 MHz to 2.5GHz
Where P is the maximum output power rating
of the transmitter in Watt (W) according to
the transmitter manufacturer and d is the
recommended separation distance in meters
(m). Field strengths from xed RF transmitters as
determined by an electromagnetic site survey a
should be less than the compliance level in each
frequency range. Interference may occur in the
vicinity of equipment marked with the following
symbol:
NOTE 1 At 80 MHz and 800 MHz, the higher frequency rangeapplies.
NOTE 2 These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption
and reection from structures, objects and people.
a. Field strengths from xed transmitters, such as base stations of radios, (cellular/cordless) telephones and
land mobile radios, amateur radios, AM and FM radio broadcast and television broadcast, cannot be predicted
theoretically with accuracy. To assess the electromagnetic environment due to xed RF transmitters, an
electromagnetic site survey should be considered. If the measured eld strength in the location in which the
Medacure Oxygen Concentrator is used exceeds the applicable RF compliance level above, the Medacure Oxygen
Concentrator should be observed to verify normal operation. If abnormal performance is observed, additional
measures may be necessary, such as reorienting or relocating the Medacure Oxygen Concentrator.
b. over the frequency range from 150 kHz to 80 MHz, the eld strengths should be less than 3 V/m.
