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

2. Working Principle

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.

3.Product Description

This oxygn concentrator 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.

7.Steps for using

①Connecting the power cord.

Insert the output terminal of the power cord into the machine power port first, in the way shown on the left figureand then insert the other terminal of the power cord into the socket .

②Insert the large diameter end of the oxygen suction pipe into the "oxygen outlet" output port of the host.

③Connecting the atomization tube.

(DH22-C1L only) as shown in the figure,connecting the atomizer to the output port of “atomization port”, and adjusting it to the right position, then wear it well.

④Wearing the oxygen inhaler

Wearing the oxygen inhaler as shown in the figure. When using a Nasal cannulas, aligning the two outlet holes with the nostril and tighten the rubber ring.

⑤Starting the oxygen generator

Turn on the “power switch”, touch the “ON/ OFF” button, the machine starts to produce oxygen, then you can inhale.

※Please adjust the oxygen concentration to the appropriate gear according to your own conditions. The recommended oxygen concentration: 70%~90% for special people (if there is no doctor’s advice, please do not inhale high concentration of oxygen); 50%~70% for the elderly and pregnant women; 30%~50% for office workers and students, or please consult a physician.

⑥Check the “air filter”

Open the air inlet cover and check that the "air filter is in place and clean.

 

8.Panel display/operating instructions

Description of the display

 

Function button

Turn on the power switch, the display shows the accumulated time and
enters the standby state.

 

ON/OFF

Gently touch the "ON/OFF" key, and the machine will enter the oxygen
making operation. At this time, the oxygen concentration value of the
display screen gradually rises to the corresponding value of the flow gear.

 

Flow button

Touching the “flow” button to adjust the oxygen concentration to the
corresponding level; the greater the flow of gas, the lower the oxygen
concentration. Levels: 1 liter, 2 liters, 3 liters, 4 liters, 5 liters, 6 liters, 7

11. Maintenance and Repair

 

Clean the shell
The shell surface should be cleaned at least once a month. Cut off the
power supply and wipe it with a clean, soft, slightly wet cloth soaked in
disinfectant. Prevent the liquid from seeping into the interior of the
machine.

Clean or replace filter and filter pad
The white air filter at the back of the machine can reduce noise, keep the
dust out and purify air. Timely cleaning and replacement of the filter are of
great importance to protect the compressor and molecular sieve and
prolong the service life of the machine. So please clean or replace it in
time.

Do not operate the oxygen concentrator when the filter and filter pad
are not installed or are wet, which could cause permanent damage to the
machine.

Generally, filters and filter pads shall be cleaned or replaced every 100
hours

▲Disassembly: Pull out the air inlet cover outward from the back of the
machine to remove the filter.
Whether to clean or replace the filter and filter cotton shall be determined
according to the actual use conditions. If the filter is dirty or clogged, it
should be cleaned or replaced immediately regardless of the using time.
Note: Filters and filter pads are consumables and need to be replaced
regularly.

▲ Cleaning: Clean with diluted detergent first and rinse with water. Install
it on the machine after it is completely dry.
Clean the oxygen inhaler and atomization components
Cleaning should be done after each use. The nasal suction heads on the
nasal cannula should be cleaned and disinfected after each use. Soak in
5% potassium permanganate solution for 5 minutes, and then clean it with
clean water; or wipe it with alcohol.

Fuse replacement
Unplug the power, use a slot screwdriver to pry open the fuse cap (as
shown in the diagram), remove the invalid glass fuse, and then install a
new one. Put the fuse cover back in place and tighten it.

Long-term idle
Make the following preparations if the machine shall be in long-term idle.

1. Cut off the power supply and put away the power cord.
2. Store the machine in a dry environment at room temperature. Do not bend the tube.
3. Avoid direct sunlight and pollution.
4. Place the machine out of reach of infants and children.

Make the following preparations before using the machine which has been in long-term idle.

1. Check the power cord for normal use.
2. Clean the oxygen tube and inhaler to avoid clogging or bending.
