generator.
1.1Product Features
The DZ-1W oxygen generator is one of the series of products produced by our
company. The product uses molecular sieve as the adsorbent, uses the advanced pressure
swing adsorption (PSA) principle, and uses air as the raw material to produce oxygen
through physical means. The following features:
1) The air is taken from nature.
2) Adopt advanced pressure swing adsorption technology (PSA), advanced process
flow and low energy consumption.
3) The product has a novel shape design, simple operation, stable operation and
convenient maintenance.

2. Precautions for safe use
When using this product, please observe the following safety precautions:
oxygen is a combustion-supporting gas ,it is not allowed to use the oxygen generator in an environment with
bright or dark fire source or with flammable or explosive danger. Smoking is strictly prohibited near the oxygen
inhaler
It is not allowed to place the oxygen tube under the bedspread or seat cushion . when there is no oxygen
absorption ,turn off the power supply of the oxygen generator .
The power supply must meet the requirements for safe use of electricity. if the power supply does not meet the
requirements, do not use oxygen generator .
Please turn off the power supply and unplug the power plug ,before cleaning ,maintaining or replacing the safety
tube of the oxygen generator .
Improper use of power cord and plug may cause burns or other electric shock hazards. do not use if the power
cord is damaged . To avoid danger, it must be replaced by a professional authorized by the manufacturer .Unplug
the power plug.
Please select safe and qualified socket and wiring board with safety electrician .
It is forbidden to plug in or unplug the power supply with wet hands . It is forbidden to drag the machine through
the traction oxygen absorption pipe or power line.
Personnel not authorized by the company shall not remove the cover for maintenance.

3. Structural characteristics and working principle
3.2Working principle
The oxygen flow of DZ-1Woxygen generation mechanism is shown in Figure 2:
Figure 2 Oxygen flow diagram of the oxygen generation mechanism
The DZ-1Wtype oxygen generator uses molecular sieve as the adsorbent and uses
the principle of pressure swing adsorption (PSA) to filter the air and send it to the
molecular sieve adsorption tower for pressure adsorption and decompression. oxygen.

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:

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.
