SAFETY NOTES
WARNING: For avoiding power outage or oxygen concentrator
operating failure, exigent oxygen user and serious patient must
equip with reserve oxygen supply (for example: oxygen cylinder,
oxygen bag). This device is to be used as an oxygen supplement
and is not considered life supporting or life sustaining.
Ⅰ
ⅠⅠ
Ⅰ.BEFORE INSTALLATION
The concentrator should always be kept upright to prevent cabinet
damage while being transported.
If the electrical source power voltage is instable that beyond
normal power rang, please add the manostat.
Please use eligible, safe power set and junction box.
Non-professional people do not open oxygen concentrator’s
cabinet.
Ⅱ
ⅡⅡ
Ⅱ.PUT POSITION
You may select a room in your house where using your oxygen
concentrator would be most convenient. Your concentrator can be
easily rolled from room to room on its casters.
Be certain to place the unit so all sides are at least 10cm away
from walls, draperies, furniture, or other obstruction. Do not place
the unit in a confined area.
Oxygen concentrator must avoid heat source, fire source, wetness,
exorbitant or over-low extra ventricular condition.
Sundries and vessel do not be placed on top of the concentrator.
3
SAFETY NOTES
 NEVER block the air openings of the unit or place it on a soft
surface, such as a bed or couch, where the air opening may be
blocked. Keep the openings free from lint, hair and the like.

Ⅲ.USING
The use of oxygen therapy requires that special care be taken to
reduce the risk of fire. Users MUST NOT SMOKE while using
this device. Keep all matches, lighted cigarettes or other sources of
ignition out of the room in which this product is located. NO
SMOKING signs should be prominently displayed. Textiles and
other materials that normally would not burn are easily ignited and
burn with great intensity in oxygen enriched air. Failure to observe
this warning can result in severe fire, property damage and cause
physical injury or DEATH.
For optimum performance, do not open or turn off the concentrator
frequently, reset after 3～5 minutes. Shorter periods of operation
may reduce maximum product life.
A spontaneous and violent ignition may occur if oil, grease or
greasy substances come in contact with oxygen under pressure.
These substances MUST be kept away from the oxygen
concentrator, tubing and connections, and all other oxygen
equipment. DO NOT use any lubricants unless recommended by
manufacturer.

ⅥⅥ
Ⅵ. TO REDUCE THE RISK OF BURNS, ELECTROCUTION,
FIRE OR INJURY TO PERSONS.
Avoid using while bathing. If continuous usage is required by the
physician’s prescription:
The concentrator must be located in another room at least
2.5m from the bath.
DO NOT come in contact with the concentrator while wet.

Ⅲ.OXYGEN ABSORBING OPERATING
1. FLOWRATE
Turn the flowmeter knob to the setting prescribed by your
physician or therapist.
NOTE: To properly read the flowmeter, locate the prescribed
flowrate line on the flowmeter. Next, turn the flow knob until the
ball rises to the line. Now, center the ball on the L/min line
prescribed.
CAUTION: If the flowrate on the flowmeter ever falls below
0.5L/min, check tubing or accessories for blocked or kinked
tubing or a defective humidifier bottle.
Meanwhile, humidifier bottle will have air bubble around the sieve
core. Then, oxygen comes from the humidifier outlet.
2. Connect nasal oxygen cannula to humidifier outlet, the other end
match the patient.
Note: The time of absorbing oxygen and the flowrate range according
to the doctor’s advices.
