Figure 3-1.  How to connect the oxygen adapter to the 

outlet filter

Do not use supplemental oxygen at flows 
above 15 L/min. Doing so could increase the 
oxygen concentration inside the device and 
increase the risk of fire.

To prevent oxygen from accumulating in the 
device and tubing, turn on the device before 
turning on the oxygen supply; shut off the 
oxygen before turning off the device.
