!!Overview!
Thank you for purchasing our domestic oxygen generator.
In order to ensure that you can use this oxygen generator safely and correctly,
please read this manual carefully before using it to fully understand and master the
performance of the product and the correct operation and maintenance methods.
This manual describes the operation, use, and maintenance of the DZ-1B domestic
oxygen generator.
1.1 Product Features
The DZ-1B household 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.

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.

3.2 Working principle
The oxygen flow of DZ-1B oxygen generation mechanism is shown in Figure 2:
Figure 2 Oxygen flow diagram of the oxygen generation mechanism
The DZ-1B type domestic 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.

5.1 Unpacking
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.
5.2 Inspection
First check the oxygen generator for transportation damage, and then check the
accessories and random documents according to the packing list.
5.3 Installation precautions
When installing the oxygen generator, please observe the following precautions:
5.4 Installation
1) Before use, loosen (or draw out) the bottom Velcro strap to avoid the air
compressor working in a vibration state.
2) Add water to the humidifier: Turn off the power of the oxygen generator, put your
fingers on the fingers of the humidifier, and gently pull out the humidifier. Pull out the
water-filled silicone plug on the humidifier, The water injection funnel delivered is
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 20 cm.
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 220-240V (+ 5 / -10V), 50 ± 1Hz 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.

inserted into the water injection hole, and an appropriate amount of pure water is poured
into the humidification cup through the funnel (the liquid level should not exceed the
highest water level line). Take out the funnel, plug the water injection silicone plug at the
water injection hole, and then insert the humidification cup Back (see Figure 3).
