2.0 Operational Check and Oxygen Concentration Test 2.1 Description of Operation Air is drawn into the NewLife Intensity Oxygen Concentrator through an external air intake gross particulate filter. Before this air enters the compressor, it passes through the unit’s suction resonator which, quiets the compressor’s suction sound. Pressurized air then exits the compressor and passes through a heat exchanger. The heat exchanger reduces the temperature of the compressed air.
an intermittent alarm if the high or low pressure indicators are activated or if the optional oxygen monitor detects lower than therapeutic levels of oxygen concentration. The alarm remains on until you correct the alarm condition or you set the I/0 power switch to the “0” position. Refer to Section 6.0 for a list of probable alarm causes. 2.3.1 Start Up/Battery Test Each time the NewLife Intensity unit is turned on, an alarm should sound for approximately five seconds.
3.0 Patient Instructions 3.1 Instructions It is important that patients thoroughly understand how to operate the AirSep NewLife Intensity unit. This enables proper treatment, as prescribed by a licensed health care provider/physician. If patients experience any discomfort or the unit alarms, they must notify their licensed health care provider/physician immediately. You, as the Equipment Provider, are responsible to see that each patient receives the Patient Manual.
4.0 Provider Instructions 4.1 Instructions To ensure that the unit’s output of oxygen is within specification, you must perform a test of the oxygen concentration. Test the unit upon delivery to a patient and at periodic intervals. Equipment Providers need to establish and implement a protocol to check oxygen concentration. (Refer to Section 2.4.) AirSep does not require preventative maintenance on the concentrator.
Electrical shock hazard. Disconnect the power cord from the electric outlet before you clean the unit to prevent accidental electrical shock and burn hazard. Only your Equipment Provider or a qualified service technician should remove the covers or service the unit. Care should be taken to prevent the NewLife Intensity from getting wet or allowing water to enter the unit. This can cause the unit to malfunction or shut down, and cause an increased risk for electrical shock or burns.
5.0 Main Components 5.1 Components The design of the AirSep NewLife Intensity Oxygen Concentrator allows for easy access and removal of most components. This allows you to perform repair and replacement of parts with minimal time and effort. To prevent accidental electrical shock or burn, be sure to set the unit’s I/0 power switch to the “0” position and disconnect the power cord of the unit from the electrical outlet before you service the NewLife Intensity Oxygen Concentrator.
5.3 Compressor The compressor is the “pump” within the oxygen concentrator that pushes the room air into the bottom of the sieve beds. This allows oxygen to flow out of the top of the sieve beds in the NewLife Intensity unit. Two different aspects of the compressor cause concern: the output and the sound level. Output Compressor output refers to how much compressed air the compressor can produce. This depends upon the model of the compressor, stroke size, bore size, and cup seal condition.
5.3.2 Capacitor Replacement The capacitor starts the compressor. If the compressor cannot start, the capacitor may be defective and require replacement. To replace the capacitor, follow the steps below: 1. Set the unit’s I/0 switch to the “0” position and disconnect the power cord. 2. Remove the side and lower front panels. 3. Disconnect the two leads to the capacitor and slide capacitor out of the tiewrap holding it in place. 4.
2. 220-240VAC units a. EQ coil = 4,400ohms +/- 10% b. Feed/waste coil = 3,220ohms +/- 10% You can also determine which coil is not operating by checking each valve to see if it becomes energized (magnetized) during unit operation. To check for coil operation, follow the steps below: 1. Remove plastic cap securing the valve coil to the valve stem. (Do not remove coil). 2.
Sieve Bed Removal To remove sieve beds, follow the steps below: 1. Set the unit’s I/0 switch to the “0” position and disconnect the power cord. 2. Remove the side and back panels. 3. Cut the tie-wrap and disconnect green tubing at each elbow fitting located on the top of the sieve beds. 4. Remove the 9/16-inch compression fitting from the bottom of each sieve bed. 5. Cut the tie-wraps securing the sieve beds to the superstructure and remove the sieve beds.
Consult the troubleshooting chart in Section 6.0 to determine when to replace the printed circuit board. The Printed Circuit Boards (PCBs) contain components that are sensitive to electrostatic discharge (ESD) and can damage the board if not handled properly. As when handling any ESD-sensitive PCB, observe standard ESD safety procedures. 5.7.1 Circuit Board Replacement Circuit Board Removal To remove the circuit board, follow the steps below: 1.
6. 7. 8. 9. 10. Remove the screws that hold the control panel to the superstructure. It is not necessary to fully remove the control panel. It is only necessary to create enough room to allow the product tank to be removed from the unit. Remove the green tubing located at the regulator outlet and at the bottom of the product tank assembly. Cut the tie wrap securing the product tank to the superstructure. Lift the product tank with regulator attached from the mounting hole and remove from the unit.
2. Remove the right side panels and back panels. 3. Use large pliers to unscrew the bonnet of the product regulator, which contains a large spring. Adjust the product regulator fully counter-clockwise to unload the spring. This makes disassembly and reassembly easier. 4. Remove the diaphragm. (Clean or replace it.) 5. Using a Phillips-head screwdriver, unscrew the diaphragm stem guide located in the center of the regulator body to gain access to the seat. 6. Remove the seat.
5.12 Buzzer Replacement 1. 2. 3. 4. 5. Set the unit’s I/0 switch to the “0” position and disconnect the power cord. Remove the left side panel. Unscrew the two Phillips-head screws that hold the buzzer to the superstructure, and solder to disconnect the buzzer leads. Solder the leads to the new buzzer, and screw the buzzer to the superstructure. Reconnect the side panel. 5.13 Hour Meter Replacement HM009-2 is a dual function hour meter.
7. Locate strain relief inside power cord receptacle. Press both ends together with pliers while pushing power cord from the back to remove power cord. Pull the power cord through the opening on the power cord receptacle. 8. Using the same length of installation for the strain relief from the original power cord, slide the strain relief onto the new power cord so that the larger lip of the strain relief faces the power cord plug end. 9.
6.0 Troubleshooting 6.1 Operating Pressure Test Testing the operating pressure is a useful diagnostic tool when a concentrator produces low oxygen concentration and requires servicing. Units functioning normally do not require operating pressure tests. Use the following procedure to test the operating pressure of the unit: 1. Set the unit’s I/0 power switch to the “0” position, and disconnect the power cord. 2. Remove the right side panel. 3.
6.2 General Troubleshooting Before reviewing the troubleshooting chart, the following steps may be useful to isolate any malfunctions: 1. Turn on the concentrator. If the unit does not turn on, refer to the troubleshooting chart. 2. Verify the outlet pressure is 20 psig (138 kPa). If the outlet pressure is not at 20 psig (138 kPa), the product regulator needs to be reset. Refer to Section 5.9. 3. Make sure the unit is cycling properly by: a. observing the flowmeter ball is stable in flowmeter.
