UNPACKING AND SETUP
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.
220/240 Volt Units – Ensure it is connected to the unit before inserting plug into an appropriate electrical outlet.
The plug on the DeVilbiss 525DS 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.
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.
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 (1.6m) 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,” all four indicator lights (Power, Service Required, Low Oxygen, and
Normal Oxygen) on the front panel will briefly illuminate and an audible signal will sound (the patient alert system) momentarily. After a few
seconds, only the “Power” and “Normal Oxygen” lights will remain on.
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owmeterknobisturnedclockwise,theowdecreases(andeventuallywillshutofftheoxygenow).Whentheknob
isturnedcounter-clockwise,theowincreases.
NOTE–Uselowoutputowmeter(part#515LF-607)forowratesunder1lpm.
NOTE–Theunitmayrequireupto20minutesfortheoxygenconcentrationandowratetostabilize.Theow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.
PATIENT ALERT SYSTEM
The DeVilbiss Oxygen Concentrator patient alert system will detect unit component failure. This system is comprised of both visible and audible alerts
which signal the patient if a malfunction should occur.
DeVilbiss OSD
®
Operation
The OSD is a 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servicing
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Specicationsforspecicalertsettings.
NOTE–AfterPowerOn,theOSDconductsacontinuousdiagnosticevaluationtocheckforafaultinthepiezoelectronics.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alertandblinkingred“ServiceRequired”lightactivate.Otherwisefortherstfteen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.
