VisionAire FamilyCAUTION: The Manufacturer recommends an alternate source ofsupplemental oxygen in the eventof a power outage, alarm condition,or mechanical failure. Consult yourphysician or Equipment Provider forthe type of reserve system required.CAUTION: It is very important to select only theprescribed level of oxygen. Do not change theflow selection unless you have been directed todo so by a licensed clinician.CAUTION: The Oxygen Concentrator may beused during sleep under the recommendationof a licensed clinician.CAUTION: Operating or storing the OxygenConcentrator outside of its normal operatingtemperature range can impair the performanceof the unit. Refer to the specification section ofthis manual for storage and operating temperature limits.CAUTION: In the event of an alarm or you observe the Oxygen Concentrator is not workingproperly; consult the troubleshooting section ofthis manual. If you cannot resolve the problem,consult your Equipment Provider.CAUTION: If the audio alarm is weak or doesnot sound at all, consult your Equipment Provider immediately.CAUTION: If the humidifier bottle tubing is notproperly connected to the humidifier bottlefitting or to the oxygen outlet, an oxygen leakcan occur.CAUTION: Normally, you should not need to adjust the flowmeter on your unit. If you turn theflowmeter adjustment knob clockwise, you willdecrease and can shut off the flow of oxygenfrom your unit. For your convenience, the flowmeter is marked in ½ LPM increments. For unitsequipped with the 2 LPM flowmeter option, theflowmeter is marked in 1/8 LPM increments forflow settings up to 2 LPM.Note: Cannula must be non-kinking, which can beused for a total length of 25 ft. (7.6 m) max.Ensure the cannula is fully inserted and secure. Youshould hear or feel oxygen flow to the prongs ofthe nasal cannula. If oxygen does not seem to flow,first verify that the flow meter ball is registeringa flow. Then, place the tip of the cannula into aglass of water; if bubbles come out of the cannula,oxygen is flowing. If bubbles do not appear, refer tothe troubleshooting section of this manual.Note: Always follow the cannula manufacturer’sinstructions for proper use. Replace the disposablecannula as recommended by the cannula manufacturer or your Equipment Provider. Additional supplies are available from your Equipment Provider.Note: The VisionAire Oxygen Concentrator must beoperated for at least five minutes at 2 LPM beforeusing the unit.The VisionAire is appropriate for usage by twousers, provided the combined flow is a minimum of2 LPM and does not exceed the maximum capacityof the concentrator.To Equipment Provider: The following oxygen administration accessories are recommended for usewith the VisionAire Oxygen Concentrator: Humidifier Bottle: Part No. HU003-1 Nasal Cannula with 7 feet (2.1 m) of tubing (6LPM max): Part No. CU002-1Note: The Manufacturer does not recommend thesterilization of this equipment.Note: If the unit has not been used for an extendedperiod of time, it needs to operate for severalminutes before power failure alarm can becomeactivated.Note: The concentrator releases warm air out thebottom of the unit which can permanently discolortemperature sensitive flooring surfaces such asvinyl. The concentrator should not be used overflooring that is sensitive to heat staining. TheManufacturer is not responsible for flooring thatbecomes discolored.Note: To prevent a void warranty, follow all manufacturers’ instructions.Note: Do not attempt any maintenance other thanthe possible solutions listed within the manual.PN MN238 C User ManualENG - 11
