1. Precautions
Warning: This is not a medical device and is not considered life-sup-
port or life-sustaining equipment.
Warning signs on the product are designed to help users understand and
use this product correctly to prevent damage and a property loss.The
main warning signs and meanings are as follows:
▲The machine shall be placed indoors. Keep the room well-ventilated
and avoid direct sunlight. Keep the product more than 30 meters away
from the walls and other objects.
▲Do not place miscellaneous items and liquid containers on the machine
case.
▲It is prohibited to stack sundries at the ventilation hole on the back of
the machine to prevent clogging of intake and exhaust, which may lead to
excessive temperature and thus cause improper shutdown or a decrease
in oxygen concentration.
▲To avoid the machine being interfered by strong electromagnetic
environment or interfering with other electrical appliances, please keep it
at least 3 meters away from other household appliances when using.
▲Do not place the machine upside down or laid it horizontally.
▲If the voltage is unstable and exceeds the range of 220±15V, please
connect the voltage regulator before use.
▲Please use a safe and qualified socket and a terminal block with safety
electrician certification.
▲Oxygen is a combustion-supporting gas. Therefore, when using the
machine,do not smoke and keep away from the fire source to avoid a fire
hazard.
▲Do not turn on and off the machine too often. Turn off the machine for
3-5 minutes before restarting to maintain the normal service life of the
machine.

2. Working Principle
▲No oil or greasy substance should be used in any part of the machine.
▲Do not use the machine without an air filter.
▲Do not bend the oxygen-inhalation tube when using the machine,
otherwise, it will affect the normal output of oxygen.
▲Unauthorized personnel should not disassemble the cover.
▲Do not bend the oxygen-inhalation tube when using The machine
otherwise it will affect the normal output of oxygen.
▲Unauthorized personnel should not disassemble the cover.
Air enters the compressor after being filtered through the inlet filter device,
and is compressed into the molecular-sieve tower for oxygen-nitrogen
separation. Oxygen passes through the molecular-sieve tower and enters
the fine sieve tower, while nitrogen is adsorbed by the molecular sieve
and discharged into the atmosphere through the separation valve. With
the increase of oxygen concentration in the fine sieve tower, oxygen is
finally delivered to the user through the oxygen delivery pipe under the
control of the electronic flow control valve.

4. List of Attachments
This product is applicable to AC 230V/50Hz(110V/60Hz) voltage. It is
equipped with a pure copper oil-free compressor and a high-quality
molecular sieve. It uses air as raw material to produce high-purity oxygen
through a new Pressure Swing Adsorption method (PSA) at room
temperature, which can be used for household supplementary oxygen
absorption.
The product is designed according to a standard higher than the standard
for household appliances. It is fitted with a large clear LED display screen.
With intelligent chips controlling the circuit, the machine has automatic
fault alarm function, timing function and overheating circuit protection
function. When the working temperature of the compressor is too high, it
will automatically stop working to better protect the safety of the compres-
sor and the whole machine.
This product is easy to operate, lightweight and portable. It is not only
suitable for home use, but also can be used in a car by using the automo-
bile power supply.Suitable for household oxygen supplement.
