TABLE OF CONTENTS
WARNING: INDICATION FOR USE
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. It is not intended for life supporting, or
life sustaining applications nor does it provide any patient monitoring
capabilities.
Ⅰ. IMPORTANT MESSAGE
Ⅱ. BEFORE INSTALLATION
To reduce the risk of electrical shock, DO NOT remove the cabinet. Refer
service to qualified service personnel.
Before operating the device, read and understand this manual.
The concentrator should always be kept upright to prevent cabinet damage
while being transported.
If the electrical source power voltage is unstable that beyond normal power
rang, please add the voltage stabilizer.
Please use eligible, safe power set and junction box.
Non-professional people DO NOT open oxygen concentrator's cabinet.
WARNING: CONTRAINDICATIONS
The oxygen concentrator is not intended for life supporting or life sustaining
applications, nor does it provide any patient monitoring capabilities.

Ⅳ. USING
You may select a room in your house where using your oxygen concentrator
would be most convenient. Your concentrator can easily move from one
room to other room by the wheels.
Be certain to place the device so all sides are at least 10 cm (4 inches) 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.
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.
The oxygen concentrator was specifically designed to minimize routine
preventive maintenance at intervals of once per year. Only professionals of
the healthcare field or persons fully conversant with this process such as
authorized or factory trained personnel should perform preventive
maintenance or performance adjustments on the oxygen concentrator.
This equipment generates, uses and can radiate radio frequency energy and,
if not installed according with the instructions, may cause harmful
interference to other devices in the vicinity. However, there is no guarantee
that interference will not occur in a particular installation. If this equipment
does cause harmful interference to other devices, which can be determined
by turning the equipment off and on, the user is encouraged to try to correct
the interference by one or more of the following measures:
● Reorient or relocate the receiving device.
● Increase the separation distance between the equipment.
● Connect the equipment into an outlet on a circuit different from that which
the other device(s) are connected.
● Consult the manufacturer or service technician for help.
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 device.
DO NOT use any lubricants unless recommended by manufacturer.

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.
DO NOT place or store product where it can drop into water or other liquid.
DO NOT reach for product that has fallen into water. UNPLUG
IMMEDIATELY.
A product should NEVER be left unattended when plugged in.
This device is to be used only in accordance with the prescription of a
physician and this User's Manual. If at any time the patient or attendant
concludes that the patient is receiving an insufficient amount of oxygen, the
supplier and/or physician should be contacted immediately. No adjustments
should be made to the flowrate unless prescribed by a physician.
Close supervision is necessary when this product is used near children or
physically-challenged individuals.
Use this product for only intended use as described in this manual.
DO NOT use parts, accessories or adapters other than those authorized by
manufacturer.
DO NOT connect the concentrator in parallel or series with other oxygen
concentrators or oxygen therapy devices.
Use of some administration accessories or certain humidifiers not specified
for use with oxygen concentrator may impair the performance.
In certain circumstances oxygen therapy can be hazardous. Manufacturer
recommends that you seek medical advice before using this product.
Avoid creation of any spark near medical oxygen equipment. This includes
sparks from static electricity created by any type of friction.
The shelf life of the device is 5 years after starting operating.
The oxygen concentrator is intended for individual use in the home. It is an
electronically operated device that separates oxygen from room air. It
provides high concentration of oxygen directly to you through a nasal
cannula. Clinical studies have documented that oxygen concentrators are
therapeutically equivalent to other types of oxygen delivery systems.
This user's manual will tell you about your concentrator and will serve as a
reference as you use your concentrator.
