OPERATING INSTRUCTIONS
1. Remove the power cord completely from the strap. Make sure
the power switch is in the "Off" position.
2. 115 Volt Units– Insert the plug into an electrical outlet.The
DeVilbiss Oxygen Concentrator uses a two-prong polarized
plug and is double-insulated to protect against electric shock.
WARNING:The plug on the DeVilbiss 515ADZ and
515ADS concentrators 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.
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.
WARNING: Oxygen promotes rapid burning. Do
not smoke when using this unit or when near a per-
son receiving oxygen therapy. Do not operate the oxygen
concentrator within a minimum of five feet (1.6m) 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 an
audible signal will sound (the patient alert system) momentari-
ly. The "Power" light also illuminates.
Only DeVilbiss Oxygen Concentrators with OSD
The OSD is an optional device within DeVilbiss concentrators
that monitors the oxygen produced by the unit.The OSD
operates as follows:
•
Normal Oxygen (green light) - oxygen purity normal
•
Low Oxygen (yellow light) - oxygen purity low–requires ser-
vicing
LT-1928
U N P A C K I N G A N D S E T U P
NOTE: If the oxygen purity continues to fall, an audible signal
will sound intermittently. If the oxygen purity continues to fall
to a low enough level, the yellow "Low Oxygen" light will turn
off and the red "Service Required" light will turn on.
NOTE: Refer to Specifications for specific 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.
NOTE: After Power On, the OSD conducts a continuous
diagnostic evaluation to check for a fault in the piezo electron-
ics. If this condition is detected by the OSD electronics at any
time during concentrator operation, the green "Normal
Oxygen" OSD light will turn off and the beeping audible and
blinking red "Service Required" light alarms activate.
Otherwise for the first fifteen minutes of operation, the
green "Normal Oxygen" light will remain illuminated
during the oxygen stabilization process.After that
time, the OSD will begin monitoring the oxygen purity
every second.
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 counter-clockwise, the flow increases.
NOTE: Use low output flow meter (part #515LF-607) for
flow rates under 1 lpm.
NOTE: The unit may require up to 20 minutes for the oxygen
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 set 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 set screw.
6. The DeVilbiss oxygen concentrator is now ready for use.
