WARNING:For oxygen can be combustion-supporting, keep oxygen concentrator far away from naked light or fire resource, no smoking or naked light.
WARNING:Keep the concentrator away from flammable and explosive areas.
WARNING: Textiles and other materials that normally would not easily burn, can ignite and burn with great intensity in oxygen enriched air.
WARNING:A spontaneous and violent ignition may occur if oil, grease or greasy substances come in contact with oxygen under pressure. ALWAYS keep these substances away from the oxygen concentrator.
Maintenance
ATTENTION:Before cleaning the dust on the net of oxygen concentrator, the plug must be pulled out in case electric attack.
ATTENTION:The filter cotton and filter are the items needed to clean, among which external filter cotton should be cleaned every 100 hours, and internal filter should be cleaned every 3000 hours.
Radio Frequency Interference
Most electronic equipment is influenced by Radio Frequency Interference (RFI). When there is strong electromagnetic interference, maybe the LCD will be slightly affected, but the machine is still running. ALWAYS exercise CAUTION with regard to the use of portable communications equipment in the area around such equipment.
Additional Safety Warnings
WARNING:DO not reach for a concentrator that has fallen into water. UNPLUG IT IMMEDIATELY.
WARNING:NEVER leave the concentrator unattended when plugged in.
ATTENTION:ALWAYS supervise closely when this product is used near children or those who require close supervision.
6
ATTENTION:In using the machine, do not open the front and back cover at all. In case
there are quality problem, do not dismantle it secretly. Any alarm or other abnormal
phenomenon has been found, connect with equipment supplier or factory.
ATTENTION:Ensure the bottom smooth exhaustion during operating, or else the machine
will be over-heated.
ATTENTION:There is intermitted exhaustion sound during operating (13 seconds in
intermission).
ATTENTION:5 minutes are needed from oxygen concentrator from warming up to reach
regular function.
ATTENTION:The machine is only for oxygen supply, and the oxygen concentration will be
up to 90% when air outlet reaches its nominal flow.
ATTENTION:In case the indicator shows abnormal oxygen, operator should declare to
dealer or factory in favor of maintain.
ATTENTION:Once open the adjust knob for flow in full, but flow meter shows zero, turn
off the machine immediately and have a check for trouble.
ATTENTION:Do not turn on or off frequently, To restart the machine after turning off, no
less than 5 minutes are necessary (namely, exhaust internal gas of the machine completely,
for if air compressor turns on with pressure, its life will be shortened )
ATTENTION:Turn up the flowmeter switch immediately when power switch is turned on.
Requirement of environment protection
The materials used in the system won’t create environment hazard.The packing materials
of the system are recyclable, and they must be collected and disposed according to the
related regulation in the country or region where the package of the system or its
accessories is opened.

extracts oxygen from atmospheric air. It will typically be an electrically-powered molecular
sieve (artificial zeolite) used to separate nitrogen from ambient air.
It could be applied widely in the hospitals at all different level, clinics, health centers and health care for the old person, mental workers and students, etc.. Whether the user is professional or not, the users could operate the oxygen concentrator by themselves after reading this user’s manual.
The oxygen concentrator can supply 1-2 patients simultaneously, with steady oxygen flowing out, safe and reliable, low cost, adjustable flow.
The key parts of the concentrator adopt anti-tiring and anti-aging design, and the planned life of the whole concentrator reaches up to 20,000 hours or 5 years, whichever comes first.
4 Using condition
1. Ambient temperature: 10℃-40℃
2. Relative humidity: 30%-85%
3. Air pressure: 700 hPa-1060 hPa
4. No corrosive gas and strong magnetic field around.
5 Scope of application:
For Medical Use:
Medical oxygen supplied by the concentrator is beneficial to cure the disease or heart and
blood vessel system, chronic pulmonary system, the brain and blood vessel system,
chronic pulmonary tuberculosis, etc.
For Health care:

Unplug the power plug
5. Oxygen purity alarm(for optional): The oxygen purity will rise to the normal level in five
minutes of operation. When oxygen purity is 85%, the green lamp is on, when oxygen
purity is <85%, red lamp is on, indicating low purity.
6. In case oxygen generator is connect with power but the whole machine is still in the state of power off with alarm sound, please check out the connection part of power whether it is in good connection, or whether there is a power off in external power supply.
9 Maintenance
1、 In the condition of power off, make a clean for the outside body by soft towel with little detergent, and then wipe it up with dry towel, once or twice per month.
2、 It is a critical step for daily maintenance to clean intake air filter, at least twice a month.
Detail steps: Remove the filter from the back of the machine, clean them with detergent
12
and clean it out with clean water completely, get ride of extra water and dry up naturally,
finally set back after dry up.
Damage: Do not operate the concentrator without the filters installed, or while filters are
wet. These actions could permanently damage the concentrator.
3、 Clean secondary filter
Clean secondary filter an interval about 100 hours, open the top cover and take out
storage case Screw，open the cover of secondary filter , take off filter cloth, then clean it
with detergent, and then clean it out with clean water completely, get rid of the extra
water, and dry it naturally, finally set back after dry up.
The secondary filter clothes
Damage: Do not operate the concentrator without the filters installed, or while filters are
wet. These actions could permanently damage the concentrator.
4、 Clean third filter
Clean third filter an interval about 500 hours, open the top cover and take out storage

13
clean it out with clean water completely, get rid of the extra water, and dry it naturally,
finally set back after dry up
The third filter
Damage: Do not operate the concentrator without the filters installed, or while filters are
wet. These actions could permanently damage the concentrator.
5、 The battery of pM Series oxygen concentrator model adopt NI-MH charge
battery(3.6V/40mAh),it is welded on the main board and there is a charge circuitry in the
board,so it could be used by a long time.But if you could not use the oxygen
concentrator continually,the battery will be at the dormancy state and its life will be
shorter.So,please charge the battery one time every month if you could not use the
oxygen concentrator continually.
6、If the user want the circuit diagram、the list of critical components、the detail of
maintenance and repair,we will supply the data about all the repairable parts which we
