5.1Unpacking
Open the box from the top surface of the box, remove the foam, open the plastic
bag, pull the back cover handle, and take out the oxygen generator.
5.2Inspection
First check the oxygen generator for transportation damage, and then check the
accessories and random documents according to the packing list.
5.3Installation precautions
When installing the oxygen generator, please observe the following precautions:
5.4Installation
1) Before use, first loosen the bottom Velcro strap to avoid vibration of the air compressor.
2) Add water to the humidification Cup: in front of the oxygen generator, at the arc gap, extend the
index finger into the humidification cup, and then pull out the humidification cup, remove the silica gel
plug, add some pure water (the liquid level should be lower than the highest water level) into
the cup, and then plug the humidification cup back into the two air holes of the front
cover.
Installation Precautions
1. The oxygen generator should be installed in an indoor ventilation place free of dust, corrosion, toxic and
harmful gases and oil mist. Avoid direct sunlight, and the distance from the wall and other objects should be greater
than 20cm.
2. The oxygen generator cannot be installed in a place with bright or dark fire sources, flammable, explosive
danger, humidity, high or low temperature, or used in a closed room(space).
3. The air inlet of the oxygen generator (above the rear shell of the machine) should be well ventilated.
4. Keep the oxygen generator stable, otherwise it will increase the noise during operation.
5. It is forbidden to lay on the oxygen generator.
6. The oxygen generator uses single-phase AC power. If the grid voltage is unstable, it will affect
the normal startup of the compressor. Please install a voltage stabilizer.
7. Before using the oxygen generator, you must loosen (or withdraw) the Velcro strap under the fuselage.

6.1Precautions for use
When using an oxygen generator, please observe the following precautions:
6.2Use
The touch display control panel of DZ-1Woxygen generator is shown in Figure 3:
Figure 3 Control panel of DZ-1Woxygen generator
Precautions for use
1. Make sure that the exhaust of the bottom of the oxygen generator is unobstructed during use, otherwise it will
affect the heat dissipation of the oxygen generator.
2. The specified performance can only be achieved after the oxygen generator is started for 10minutes.
3. There is a gap of exhaust sound when the oxygen generator is in use (about once every 4seconds).
4. Do not use oil, grease or other similar substances on or near the oxygen generator.
5. Inuse, when the water in the humidifying cup is insufficient, make up for it in time.
6. The oxygen generator cannot be started frequently. It shouldbe restarted after 5minutes after shutting down.
7. Molecular sieves will age due to factors such as the use time and the environment, which will cause the
recoverability of the oxygen production to decrease. When this phenomenon is found, please contact the
maintenance point or the manufacturer to replace the molecular sieve.
8. When the oxygen generator is stopped, you must unplug the power cord.
9. During the use of the oxygen generator, the shutdown due to the high ambient temperature and the thermal
protection of the air compressor is a normal phenomenon. The power must be turned off and the machine cooled
down before being used.

operation
1）Power on: plug in the power cord and power on. Turn on the power switch (the
position is at the lower left part of the concentrator), the concentrator will start, enter the
power on state, the touch key of the concentrator will be fully on, and enter the standby state.
2) Continuous oxygen generation: touch the "oxygen generation" button on the control
panel, and the oxygen generator will enter the "continuous oxygen generation" working state
with the voice prompt of real person. The continuous oxygen making time of the oxygen
generator is displayed on the screen, and the accumulated use time of the oxygen generator is
displayed at the bottom of the screen.
3) Adjust the flow: touch the "flow" key on the control panel. With the voice prompt of the
real person, the oxygen flow of the oxygen generator increases by 1L, which can be adjusted
to 7L at most. After reaching the maximum 7L, touch the "flow" key on the control panel.
With the voice prompt of the real person, the oxygen flow of the oxygen generator decreases
by 1L, which can be adjusted to 1L at least.
4) Start to inhale oxygen: insert the oxygen pipe into the "oxygen port", confirm that there
is oxygen output at the nose of the oxygen pipe, and then wear a good oxygen pipe (please
refer to the instructions for use of the oxygen pipe for wearing the oxygen pipe) to start to
inhale oxygen.
5) Atomization operation: first take out the oxygen absorption tube, then insert the
atomizer silicone tube into the "atomization port", touch the "atomization" key on the control
panel, and bring the atomizer to atomize. (please refer to the instruction manual of atomizer
for atomizer and atomization dosing operation flow.) turn off the "atomization" key after
atomization.
6) Time setting: touch the "timing" key on the control panel, and the oxygen generator will
enter the "timing oxygen" state. Users can preset the oxygen making time according to their
needs. Each time they touch the "timing" key, the preset time increases by 15 minutes, and
the maximum timing is 9 hours and 45 minutes. When the timing exceeds 9 hours and 45
minutes, they touch the timing key again, and the time starts to accumulate from 0. After the
countdown is reset to zero, the oxygen generator enters the standby working state and the
compressor stops working.
