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).

6.1 Precautions for use
When using an oxygen generator, please observe the following precautions:
6.2 Use
The touch display control panel of DZ-1B oxygen generator is shown in Figure 4:
Figure 4 Control panel of DZ-1B oxygen 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 10 minutes.
3. There is a gap of exhaust sound when the oxygen generator is in use (about once every 4 seconds).
4. Do not use oil, grease or other similar substances on or near the oxygen generator.
5. In use, when the water in the humidifying cup is insufficient, make up for it in time.
6. The oxygen generator cannot be started frequently. It should be restarted after 5 minutes 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.
