Operating the DeVilbiss 5 Liter Oxygen
Concentrator
1.
Remove the power cord completely from the strap. Make
sure the power switch is in the "Off" position.
2.
Insert the plug into an electrical outlet.The DeVilbiss 5
Liter Oxygen Concentrator has a two-prong polarized plug
and is double-insulated to protect against electric shock.
NOTE – The plug on the DeVilbiss 5 Liter 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.
CAUTION – 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.
WARNING – Oxygen promotes rapid burning. Do
not smoke when using this unit or when near a person
receiving oxygen therapy. Do not operate the oxygen
concentrator within a minimum of five feet (1.5 meters)
from hot, sparking, or burning objects or naked flames.
Do not use in rooms heated by paraffin or portable gas
heaters.
3.
Press the power switch to the "On" position.When the
unit is turned on, the "Service Required" light will
illuminate and audible signal will sound (the patient alert
system) momentarily.The "Power" light also illuminates.
Only DeVilbiss Concentrators with OSD
The OSD is an optional device within DeVilbiss concentrators
that monitors the oxygen produced by the unit.The OSD oper-
ates as follows:
•
Normal Oxygen (green light) - oxygen purity normal
•
Low Oxygen (yellow light) - oxygen purity low
(requires servicing).
NOTE – If the oxygen purity continues to fall, an audible signal
will sound intermittently. Refer to speifications for alarm settings.
When the unit with the OSD is turned "On, " all four indicator
lights (Power, Service Required, Low Oxygen, and Normal Oxygen)
on the front panel will briefly illuminate.After a few seconds, only
the "Power" and "Normal Oxygen" lights will remain on.

For the first fifteen minutes of operation, the green "Normal
Oxygen" light will remain illuminated during the oxygen stabi-
lization process. After that time, the OSD will begin monitoring
the oxygen twice every second.
NOTE – If the "Service Required" light illuminates and the
audible signal alarms during operation, the unit will automatical-
ly shut off.Turn the power switch "Off." Then turn the unit
"On" again. If the "Service Required" light remains on, refer to
the Troubleshooting Chart.
4.
Slowly turn the flow meter knob until the flow meter ball
is centered on the line next to the appropriate flow rate.
NOTE – When the flow meter knob is turned clockwise, the
flow decreases (and eventually will shut off the oxygen flow).
When the knob is turned counterclockwise, the flow increases.
NOTE – If the flow meter is turned to approximately 0 LPM, it
may activate the Restricted Flow Alarm.The unit will continue
to run, however an intermittent audible and visible alarm may
be activated.
NOTE – Use a low output flow meter (part #515LF-607) for
flow rates under 1 LPM.
NOTE – The unit may require up to 20 minutes for the oxy-
gen concentration and flow rate to stabilize.The flow rate
should be monitored and readjusted if necessary.
5.
The flow meter has a locking device. If it is necessary to
preset and lock in the prescribed flow rate, tighten the hex
screw located on the hex nut just below the control knob
using a 1/16" Allen bit. No adjustment can be made
without loosening the hex screw.
6.
The DeVilbiss 5 Liter Oxygen Concentrator is now ready
for use.
Performing Initial Inspection
It is suggested that an initial inspection be performed upon
receiving the oxygen concentrator.
1.
After removing the oxygen concentrator from the carton,
examine it for any external damage. If shipping damage has
occurred, contact the Sunrise Medical Shipping/Traffic
Department at 1-800-338-1988 for specific instructions.
2.
Record the number of hours on the hour meter.
3.
Check to be sure the extended life filter and the air filter
are in place.
4.
Plug the unit into an electrical outlet, turn the unit "On,"
and check the audible and visible alarms.
5.
Set the flow meter at 5 LPM and let the unit run for at
least 20 minutes.
6.
Using SMART Track or an oxygen analyzer, check the
concentration at 5 LPM.
7.
Using SMART Track or a stop watch, check the cycle time
for bed 1 and bed 2 at 5 LPM.
NOTE—If the unit fails to operate properly (i.e., oxygen con-
centration or cycle times are not within specification) or if
internal damage is found, contact the Sunrise Medical Service
Department at 1-800-338-1988.
