BEFORE OPERATING YOUR OXYGEN CONCENTRATOR
Check your oxygen concentrator and accessories for proper operation. Bend the nasal prongs over and squeeze tight to stop the ow of
oxygen. Look at the ow meter to see that the indicator ball on the ow meter drops to zero. If the indicator ball does not drop to zero, check
all connections for possible leaks. Parts to check for leaks are: tubing connections, humidier bottle and other accessories like rebreaks.
Repeat these steps until the ow meter ball drops to zero. Contact your dealer or service supplier immediately if you encounter any
problems.
1. Before operating your unit, always check to be sure the air lter (located on the back of your unit) is clean. Proper cleaning of this lter
is discussed in the Caring For Your Concentrator section on page 7.
2. Attach the appropriate oxygen accessories to the oxygen outlet.
Oxygen Tubing Connection:
a. Thread the supplied oxygen outlet connector onto the oxygen outlet.
b. Attach the oxygen tubing directly to the connector (Figure 1).
Oxygen Tubing Connection With Humidication:
If your physician has prescribed an oxygen humidier as part of your therapy, follow these steps (If using a prell, go to step b.):
a. Fill the humidier bottle as per manufacturer’s instructions.
b. Thread the wing nut located on the top of the humidier bottle to the oxygen outlet so that it is suspended (Figure 2). Make sure
it is securely tightened.
c. Attach the oxygen tubing directly to the humidier bottle outlet tting (Figure 3).
3. Your physician has prescribed either a nasal cannula or face mask. In most cases, they are already attached to the oxygen tubing. If
not, follow the manufacturer’s instructions for attachment.
4. Remove the power cord completely from the line cord strap. Make sure the power switch is in the “Off” position and insert the plug
into the wall outlet. The unit is double insulated to guard against electric shock.
NOTE– (only 120 volt units) The plug on the DeVilbiss oxygen concentrator has one blade wider than the other. To reduce the risk of
electric shock, this plug is intended to t in a wall outlet only one way. Do not attempt to defeat this safety feature. Your healthcare
provider should verify the compatibility of the oxygen concentrator and all of the parts used to connect to the patient before use.
WARNING
Improper use of the power cord and plugs can cause a burn, re or other electric shock hazards. Do not use the unit if the
power cord is damaged.
OPERATING YOUR DEVILBISS OXYGEN CONCENTRATOR
WARNING
Oxygen causes rapid burning. Do not smoke while your oxygen concentrator is operating, or when you are near a person
utilizing oxygen therapy. Keep the oxygen concentrator and cannula at least 2 m (6.5 feet) from hot, sparking objects or naked
sources of ame.
The DeVilbiss 10-liter oxygen concentrators are equipped with a re mitigating outlet tting that prevents propagation of re into
the unit.
In order to prevent a re propagating from the patient through the cannula towards the unit, a means of protection should be
located as close to the patient as practicable. Please contact your provider for this means of protection.
1. Press the power switch to the “On” position. When the unit is turned “On,” all three lights (Service Required, Low Oxygen and Normal
Oxygen) on the front panel will illuminate briey and an audible signal will briey alarm conrming that the LEDs and audible signal
are functioning properly. The unit will then operate in “start up” mode with the Low Oxygen light lit until a normal oxygen level is
achieved, at which time the Normal Oxygen light will remain lit. The “start up” may take up to 15 minutes.
NOTE– DeVilbiss recommends for optimal service life that the DeVilbiss Oxygen Concentrator be operated for at least 30 minutes after it is powered on. Shorter periods
of operation, operating in extreme temperature/humidity conditions or in the presence of contaminates, and/or handling and storage conditions outside those specied,
may affect the long term reliable operation of the product.
WARNING
Oxygen makes it easier for a re to start and spread. Do not leave the nasal cannula or mask on bed coverings or chair cushions if the oxygen concentrator
is turned on but not in use, the oxygen will make the materials ammable. Turn the oxygen concentrator off when not in use to prevent oxygen enrichment.
NOTE– If the audible signal alarms but the unit is not operating, there is no power to the unit. Refer to the Minor Troubleshooting chart on page 7 and contact your
DeVilbiss provider if necessary.
NOTE– If an audible low-frequency vibration sound is detected, the unit is not operating properly. Refer to the Minor Troubleshooting chart on page 7, and contact your
DeVilbiss provider if necessary.
2. Check the ow meter to make sure that the ow meter ball is centered on the line next to the prescribed number of your ow rate.
CAUTION– It is very important to follow your oxygen prescription. Do not increase or decrease the ow of oxygen – consult your physician.
NOTE– Your DeVilbiss provider may have preset the ow meter so that it cannot be adjusted.
NOTE– If the ow meter knob is turned clockwise, the ow decreases (and eventually will shut off the oxygen ow). If the knob is
turned counterclockwise, the ow increases.
NOTE– For prescriptions of 10 LPM, be sure the ball is centered on the 10 liter line. The ball should not touch the red line. Setting the
ow higher than 10 may cause the oxygen purity level to drop.
NOTE– The low-ow alarm may activate if the ow meter ball is set below 2 lpm. The unit will continue to run; however, the Service
Required light will come on accompanied by an audible alarm. Adjust the ow meter to your prescribed ow. Do not use a low-output
ow meter with this concentrator.
3. Your DeVilbiss concentrator is now ready for use, properly position the cannula or mask (Figure 4) and allow 15 minutes for the oxygen
concentrator to reach stated performance.
