Anymaterials that will burn in air, and some that will not, are easily ignited and burn rapidly in highconcentrations of OXYGEN . For safety concerns, it is necessary that all sources of ignition be keptaway from the product and preferably out of the room in which it is being used. NO SMOKING signs should be prominently spontaneous and violent ignition may occur if oil, grease or greasy substances come in contactwith OXYGEN under pressure.

4 These substances MUST be kept away from the OXYGEN concentra-tor, tubing and connections, and all other OXYGEN equipment. DO NOT use any lubricants unlessrecommended by optimum performance, INVACARE recommends that each concentrator be on and running fora minimum of 30 minutes at a time. Shorter periods of operation may be harmful for maximumproduct it has a damaged cord or plug, if it is not working properly, if it has been dropped ordamaged, or dropped into water, call Qualified Service Personnel for examination and the cord away from HEATED or HOT drop or insert any object into any block the air openings of the product or place it on a soft surface, such as a bed or couch,where the air opening may be blocked. Keep the openings free from lint, hair and the humidifier with water to the level shown by the manufacturer. DO NOT recommends that Crush-Proof OXYGEN tubing (supplied by INVACARE ) be used with thisproduct and NOT exceed 50 ft.

5 ( ) in THE FOLLOWING INFORMATION BEFORE OPERATING THIS INVACARE OXYGEN concentrator was specifically designed to minimize routine preventativemaintenance at intervals of once per year. Only professionals of the healthcare field or personsfully conversant with this process such as authorized or factory trained personnel shouldperform preventative maintenance or performance adjustments on the OXYGEN FREQUENCY INTERFERENCEMost electronic equipment is influenced by Radio Frequency Interference (RFI). CAUTION shouldbe exercised with regard to the use of portable communications equipment in the area aroundsuch SUMMARY (Continued)SAFETY SUMMARYSAFETYSUMMARYWARNINGALWAYS unplug this product IMMEDIATELY after using while bathing. If continuous usage is required by the physicians prescription:The concentrator must be located in another room at least seven (7) feet from the NOT come in contact with the concentrator while NOT place or store product where it can drop into water or other NOT reach for product that has fallen into water.

6 UNPLUG REDUCE THE RISK OF REDUCE THE RISK OF BURNS, ELECTROCUTION, FIRE OR INJURY TO device is to be used only in accordance with the prescription of a physician and this OwnersManual. If at any time the patient or attendant conclude that the patient is receiving an insufficientamount of OXYGEN , the supplier and/or physician should be contacted immediately. No adjust-ments should be made to the flowrate unless prescribed by a product should NEVER be left unattended when plugged supervision is necessary when this product is used by, on or near children or bedconfined this product for only intended use as described in this NOT use unauthorized parts, accessories or adapters other than those authorized SUMMARYSAFETY SUMMARY (Continued)SAFETYSUMMARYGROUNDING INSTRUCTIONSA. This product should be grounded. In the event of an electrical short circuit, groundingreduces the risk of electric shock by providing an escape wire for the electrical product is equipped with a cord having a grounding wire with a grounding plug.

7 Theplug must be plugged into an outlet that is properly installed and USE OF THE GROUNDING PLUG CAN RESULT IN A RISK OF ELECTRICAL repair or replacement of the cord or plug is necessary, do not connect the grounding wire toeither flat blade terminal. The wire with insulation having an outer surface that is green with orwithout yellow stripes is the grounding wire. Check with a qualified electrician or serviceman ifthe grounding instructions are not completely understood, or if doubt exists as to whether theproduct is properly This product is for use on a normal 120 V circuit and has a grounding plug that looks likethe plug illustrated in sketch A shown at the bottom of the page. A temporary adapter,which looks like the adaptor illustrated in sketches B and C, may be used to connect thisplug to a 2-pole outlet as shown in sketch C if a properly grounded outlet is not temporary adaptor should be used only until a properly grounded outlet (sketch D)can be installed by a qualified electrician.

8 The green colored rigid ear, lug and the likeextending from the adapter must be connected to a permanent ground such as properlygrounded outlet box cover.
