The air we breathe is made up of approximately 21% oxygen and 79% nitrogen. Oxygen concentrators filter nitrogen out of room air, collect the remaining oxygen and dispense it at the prescribed flow rate at 90% to 95% purity. The use of this concentrator does not reduce the oxygen in the room air because of the small amount of oxygen required.

1. TURNING ON YOUR OXYGEN:

A. Plug the concentrator into a properly grounded wall outlet. DO NOT use an extension cord and DO NOT plug into an outlet controlled by a switch or dimmer.

B. Attach your cannula to the oxygen outlet.

C. Set the power switch to the "ON" position.

D. Turn the flow adjustment knob until the flow meter registers the flow rate prescribed by your doctor.

E. Put on the cannula and adjust for comfort. (see instructions included with your cannula.)

F. If you are using a humidifier, refer to the manufacturer's instruction sheet included with your humidifier for proper use and maintenance.

2. TURNING OFF YOUR OXYGEN:

A. Remove the nasal cannula.

B. Set the power switch to the "OFF" position.

C. It is NOT necessary to turn the flow control "OFF" after it has been set properly. It should be checked, however, each time the concentrator is turned "ON" and periodically during use. The flow control may require minor adjustments from time to time.

3. ROUTINE WEEKLY CARE:

A. Clean the air inlet filter weekly:

1. Turn the power off.
2. Grasp the filter and pull it out.
3. Wash the filter in warm sudsy water and rinse thoroughly.
4. Dry filter by removing excess water with a lint free towel.
5. Replace filter and turn power back on.

B. The outer surfaces of the concentrator may be cleaned with a soft moistened towel.

4. SAFETY PRECAUTIONS:

A. DO NOT operate the oxygen concentrator without a filter or with a dirty filter.

B. DO NOT operate the concentrator with an extension cord.

C. DO NOT attempt to service the concentrator beyond those guidelines that you have been given.

D. DO NOT allow an open flame within 5 feet of the oxygen.

E. DO NOT use any type of aerosol spray near the Oxygen Concentrator.

F. DO NOT use any portable heaters in the same room that the oxygen is being used or stored in.

G. IF:

• The mechanical failure alarm doesn't sound appropriately when you first turn the unit on,
• The alarm sounds while you are using the machine, or
• You have a power failure,

Turn the unit OFF and use the back-up oxygen cylinder and call us at 716-667-9600 or toll free at 1-866-667-9600.
