How To Operate Your Oxygen Concentrator
 
 
Review the following information before you operate your oxygen concentrator.
 
5.1 Humidifier 
Bottle
(Optional)
If additional humidification is required with your oxygen therapy, perform the 
following steps each time you fill or clean the humidifier, which may have been 
initially set up for your use. 
1. Remove the humidifier bottle from the humidifier bottle recess area. 
2. Open the humidifier bottle. If you have a pre-filled bottle, do not perform this 
step. Proceed to step 5.
3. Fill the humidifier bottle with cool or cold water (distilled water is preferred)
to the fill line indicated on the bottle. DO NOT OVERFILL.
4. Re-connect the top cover to the humidifier bottle.  
5. Place the humidifier bottle in the humidifier bottle recess area on the back of 
the concentrator and connect the humidifier bottle tubing to the oxygen outlet 
and the humidifier bottle fitting.  
 
If the humidifier bottle tubing is not properly connected to the humidifier 
bottle fitting or to the oxygen outlet, an oxygen leak can occur. 
 
 
 
5.2 Cannula 
Connection
Connect the tubing and cannula to the unit’s oxygen outlet, or to the optional 
humidifier’s oxygen outlet.
