How to use:

PREPARE WORK 

1.Unscrew the bottle from the humidifier clockwise. Fill the bottle with pure water (or distilled water) to the level between MAXIMUM and MINIMUM. DO NOT fill humidifier bottle over MAXIMUM level. (Figure 5) 

2. Screw securely the bottle back counterclockwise. (Recommend to use Yuwell Humidifier p/n: 2.05.014.114) 

3. Connect the power supply.

CAUTION:

1) If the concentrator has a damaged cord or plug, if it is not working properly, if it has been dropped or damaged, or dropped into liquid, call Qualified Service Personnel for examination and repair. 

2) Keep the cord away from HEATED or HOT surfaces. 

3) Do not move or relocate concentrator by pulling on the cord. 

4) Do not use extension cords with this unit. 

NOTE: Concentrator may be used during the initial start warmup time (approximately 30 min) while waiting for the O2 purity to reach maximum. 

II. OXYGEN ABSORBING OPERATION 

1. FLOWRATE (Figure 6 ) 

• Turn the flowrate knob to the setting prescribed by your physician or therapist. 

NOTE: To properly read the flowrate, 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 oxygen outlet. 

2. Connect nasal oxygen cannula to oxygen outlet, the other end match the patient. 

Note: The time of absorbing oxygen and the flowrate range according to the 

doctor's advices. 

NEBULIZING OPERATION

• Fill proper medicinal liquid in the nebulizing cup (Please follow the doctor's advices or don't exceed the maximum reticle of the nebulizing cup). 


• Upward pull out the nebulizing cover on the nebulizing interface. 

Counter clockwise

Nebulizing Cap 

Nebulizing Interface 

• Connect the air hose to nebulizing cup and nebulizing interface, then turn on the power of the oxygen concentrator, now can begin nebulizing therapy immediately. 


• When drug nebulizing have finished, turn the nebulizing cover right to nebulizing interface for tightening. If you won't breathe oxygen, please turn off the oxygen concentration. 


• Pull out the air hose, pull the mouthpiece, downward pull the nebulizing cup's cap, empty remained medicinal liquid in the nebulizing cup, then wash 


• the air hose, mouthpiece, nebulizing cup's cap, nebulizing baffle, nebulizing cup, ripple tube, Tpiece, etc. , with pure water or immerge them in warm water for about 15 minutes. In order to wash them healthy, you may add some vinegar in water. (NOTE: DO NOT cook the accessories above for wash or wash them with boiled water, in case they'll distort when heating). 


• After finishing cleaning, must dry all the components before storage. 

NOTE: The timing for using nebulizer must follow the doctor's advices.

• 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. 

WARNING: CONTRAINDICATIONS 

• The oxygen concentrator is not intended for life supporting or life sustaining applications, nor does it provide any patient monitoring capabilities. 

Symbol Description 

WARNING Describes a hazard or unsafe practice that if not avoided can result in severe bodily injury, death or property damage. 

CAUTION Describes a hazard or unsafe practice that if not avoided can result in minor bodily injury or property damage. 

I . IMPORTANT MESSAGE 

• 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. 

II. BEFORE INSTALLATION 

• 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. 


• Nonprofessional people DO NOT open oxygen concentrators cabinet.

II. LOCATING 

• 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 overlow 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. 

IV. 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 device. 

DO NOT use any lubricants unless recommended by manufacturer. 

V. MAINTENANCE 

• 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.
