Place the concentrator at least 3 inches from walls, furniture and draperies. Avoid placing on deep pile carpets or near heaters, radiators or hot air registers. Plug concentrator into electrical outlet. Extension cords are never to be used. Connect the humidifier if prescribed. Turn unit ON and Set the flow meter to the prescribed flow rate. Centre the ball on the L/min line of the flow meter. Note: The flow must be set after everything is connected. Connect up to 50 feet of crush proof delivery tubing and a 7 foot cannula. The concentrator may be used during the initial start warm up period (approximately 30 min.) while waiting for the O2 purity to reach maximum. 1

Routes 120 VAC To Compressor, Cooling Fan & Hour Meter Pressure Transducer Determines When 4-Way Valve Shifts Based On Pressure In The Product Canister O2 Sensor Determines Level Of Oxygen Delivered To Patient SENSO 2 TECHNICAL ILLUSTRATION OR RED YELLOW GREEN SENSO2 OPERATION A precise amount of gas passes through the orifice to the oxygen sensor. As the gas enters the sensor it passes a screen and contacts the top electrode of the Zirconia Disk. Power applied from the top electrode to the bottom electrode heats the disk to over 570 degrees F ( degrees C). Oxygen molecules on the top of the disk pick up an extra electron, becoming oxygen ions. The ions are attracted to the electrode on the bottom of the disk. Due to the structure of the Zirconia, only the oxygen ions can pass through it. Once the ions reach the bottom electrode, the extra electron is dropped from the oxygen molecule as the molecule returns to air. The number of electrons is directly related to the oxygen % in the gas. The electrons travel to the PCB where they are counted and translated into the oxygen concentration reading. 10

14 Homefill II Compressor Specifications Double Insulated complying with UL1097(US) and CAN/CSA C22.2 No. 68 (Canada). Operating Temperature: 50 to 90 F(10 to 35 C) Storage Temperature: -10 to 150 F (-23 to 65 C) Input Pressure Required: PSI Input Flow Required: 2 L/min Input O2% Required: 90% minimum Weight: 33 lbs. Shipping Weight: 39 lbs. Set Up Select location at least 3 away from walls, draperies or furniture on a hard flat stable surface such as a table. Plug the power cord into the back of the unit and into the wall outlet. Insert one end of the interconnect hose into the outlet fitting on the back of the concentrator and insert the opposite end into the fitting on the side of the compressor. Turn the concentrator ON and verify the flow is not above 3 L/min to the patient. Perform Cylinder Pre-fill inspection. 14

15 Cylinder Pre-fill Inspection FDA requires the use of only Invacare provided cylinders approved for use with the Homefill system. Verify the hydrostatic testing date. (Must be tested every 5 years) Inspect the cylinder for damage such as: dents, burns, oil, grease or any other signs of damage. Inspect the valve for debris, oil, grease, or other signs of damage. Inspect the inside of the valve for signs of corrosion. Connecting Cylinder to Compressor Verify cylinder pressure is less than 1500 psig. (pound-force per square in guage) Do Not attempt to top off cylinders. Set the regulator flow knob to 0. Position the cylinder in the compressor cradle. Align the cylinder fill port with the compressor fill port. Pull UP on the connector fill port ring while pushing DOWN on the cylinder to insert the cylinder into the compressor fill port. The cylinder is properly connected when an audible click is heard. Turning Compressor On Ensure the concentrator is ON and the flow to the patient is not greater than 3 L/min. Push the power switch to the ON position. The following will occur: 0-3 Minutes: Prior to August 2006: The WAIT (Yellow) light will be on while the compressor warms up (first 3 minutes). The O2 BELOW Normal (Yellow) light will be on while the compressor warms up. After 3 Minutes: The FILLING (Green) light will be on while the cylinder is filling. NOTE: If the O2 BELOW NORMAL (Yellow) light will come on if the O2% from the concentrator drops below 90%. 15

16 Indicator Light Explanation None: Compressor is OFF Wait Yellow: Prior to August 2006:Compressor is ON and warming up (3min) O2 Below Normal Yellow: O2 from the concentrator is less than 90% after 3 minute warm up period. Filling Green: Compressor is ON and cylinder is filling. Full Green: Compressor is ON and cylinder has completed filling. Attention Red (Audible Alarm): Compressor is ON cylinder not filling.
