DeVilbiss 525 Series Instruction Manual page 8

SETTING UP YOUR OXYGEN CONCENTRATOR
1 Position your unit near an electrical outlet in the room where you spend most of your time
NOTE – Do not connect to an electrical outlet controlled by a wall switch.
DANGER
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 flame.
2. Position your unit on a flat surface at least 6 inches (16 cm) from walls, draperies or any other objects that might prevent the proper
flow of air in and out of your oxygen concentrator. The oxygen concentrator should be located in a well-ventilated area to avoid
pollutants or fumes
NOTE – To move the unit, firmly grasp the handle located on the top of the unit, rolling and/or lifting the unit over pathway
obstacles.
3. Before operating your unit, always check to be sure the filter door vents (located on the back of your unit) are clean. Proper cleaning
is discussed in the Caring For Your Concentrator section on page 9
4 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 Humidification:
If your physician has prescribed an oxygen humidifier as part of your therapy, follow these steps (If using a prefill, go to step b.):
a. Fill the humidifier bottle as per manufacturer's instructions.
b. Thread the wing nut located on the top of the humidifier 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 humidifier bottle outlet fitting (Figure 3).
NOTE – 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.
NOTE – Your healthcare provider should verify the compatibility of the oxygen concentrator and all of the parts used to connect to the
patient before use.
5 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
WARNING
Ensure the mains power cord is fully inserted into the concentrator connector (230 volt units) and the power cord plug is
completely inserted into a fully functioning AC wall outlet Failure to do so may cause an electrical safety hazard
NOTE – (only 115 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
fit in a wall outlet only one way. Do not attempt to defeat this safety feature.
NOTE – To check your oxygen concentrator and accessories for proper operation; 1. Check the output flow by placing the end of the nasal cannula under the surface of a
half-full cup of water and look for the bubbles. 2. Check the system for leaks by bending the nasal prongs over and squeeze tight to stop the flow of oxygen. Look at the flow
meter to see that the indicator ball on the flow 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, humidifier bottle and other accessories like firebreaks. Repeat these steps until the flow meter ball drops to zero. Contact your provider or service
supplier immediately if you encounter any problems.
WARNING
Improper use of the power cord and plugs can cause a burn, fire or other electric shock hazards. Do not use the unit if the power cord is damaged.
OPERATING YOUR DEVILBISS OXYGEN CONCENTRATOR
DANGER
• 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 flame.
• DeVilbiss oxygen concentrators are equipped with a fire mitigating outlet fitting that prevents propagation of fire into the unit.
CAUTION
When the unit is turned "ON", as part of the normal start-up process, all three lights (Service Required, Low Oxygen and Normal
Oxygen) on the front panel should illuminate and the audible alarm should sound. If ANY of the lights on the front panel DO NOT
illuminate or the audible alarm DOES NOT sound, this indicates the alert system is not functioning properly Refer to the
Troubleshooting chart on page 10 and contact your DeVilbiss oxygen provider if necessary
WARNING
In order to prevent a fire 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 briefly and an audible signal will briefly alarm confirming 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
specified, may affect the long term reliable operation of the product.
