SHIPPING AND HANDLING

SHIPPING AND HANDLING

SHIPPING AND HANDLING INSTRUCTIONS Before you install and operate the concentrator, please refer to Platinum 5 owner's manual. The Platinum 5 concentrator should always be kept in the upright position to prevent cabinet damage while being transported. The shipping container has been designed to assure maximum protection of the concentrator. If the concentrator is to be reshipped by common carrier, it should be packed in a new carton. Additional cartons are available from Invacare. The air compressor suspension system has been engineered to withstand severe motion and orientation.

UNPACKING (FIGURE 1) 1. Check for any obvious damage to the carton or its contents. If damage is evident, notify the carrier, or Invacare. 2. Remove all loose packing from the carton. 3. Carefully remove all the components from the carton. NOTE: Retain carton and packing materials for storage of the Platinum 5.

INSPECTION 1. Examine exterior of the oxygen concentrator for nicks, dents, scratches or other damages. Inspect all components.

STORAGE 1. Store the repackaged oxygen concentrator in a dry area. 2. DO NOT place other objects on top of the repackaged concentrator.

INSTALLATION/SEQUENCE OF OPERATION

INSTALLATION / SEQUENCE OF OPERATION When your new Platinum 5 concentrator arrives, it should be checked for proper operating conditions. 1. If the unit has been in below-freezing temperatures, allow it to warm up to room temperature before operating. 2. The concentrator may need to be turned on for 4 to 5 seconds to charge the Battery Free Power Loss Alarm. Connect power cord to outlet and turn the concentrator on. Turn flow control knob counterclockwise and flow will begin immediately. Set flow rate to 5L/ min. Let the unit run for 30 minutes then turn unit off. 3. Unplug the power cord and press ON/OFF (I/O) switch to the ON (I) position. An intermittent audible alarm will sound. This confirms proper operation of the Battery Free Power Loss Alarm. Turn ON/OFF switch OFF (O). 4. Connect power cord to outlet and turn on concentrator. Unit will BEEP on start-up. 5. Check the oxygen concentration per specifications after 30-40 minutes running time.

SEQUENCE OF OPERATION Turning ON (I) the power switch, applies 120 VAC to the compressor motor, hour meter, transformer, cooling fan and the Printed Circuit (P.C.) Board. Room air enters the compressor via the cabinet filter and the compressor inlet filter. The air is compressed by the wobble pistons in the compressor to a pressure of 21 p.s.i. (144.79 kPa). As increased pressure creates increased temperature, a heat exchanger is used to lower the temperature before the air enters the 4-way valve. It is then channeled to a sieve bed containing the adsorption material. Restriction downstream of the sieve bed causes pressure to build up inside the sieve bed which is necessary for the adsorption process. A small amount of relatively pure oxygen enters the top of the second bed through a restrictive leak in the P.E. Valve with the balance entering a storage tank. The nitrogen removed is exhausted back from the bed through the 4-way valve into room air. A muffler is located at the exhaust end of the valve to muffle the sound of the exhaust as it exits the concentrator. The oxygen not being used to exhaust is channeled into the storage tank. The pressurized oxygen is regulated down to 5 p.s.i. (34.4 kPa), enters an accurate flow-measuring device, flows through Outlet HEPA filter, a check valve and out to the patient. The electrical activation of the 4-way Valve is accomplished every 8 to 15 seconds by the pressure sensor and P.C. Board electronics when the pressure reaches a set point of 21 p.s.i. (kPa). The time between cycles is dependent on altitude, flow rate and internal environmental factors. A Pressure Equalization (P.E.) valve opens just prior to the shift of the 4-way valve. This allows highly concentrated oxygen to enter the just exhausted bed from the top. This additional pressure allows the bed to start its cycle at a higher pressure. The P.E. Valve will close just after the shift of the 4-way Valve. Part No. 1110538

INSTALLATION/SEQUENCE OF OPERATION

INSTALLATION / VERIFICATION OF BATTERY FREE POWER LOSS ALARM

INSTALLATION/SEQUENCE OF OPERATION

INSTALLATION / SEQUENCE OF OPERATION If main power is lost, the Battery Free Power Loss Alarm will sound a short "BEEP", with a long pause after. All units are equipped with a diagnostic alarm system that signals if the pneumatic pressure or electrical systems malfunction. The Troubleshooting Guide in this manual explains the alarm system signals and reasons, in detail, for your convenience.

SENSO2 OXYGEN SENSOR TECHNOLOGY CERAMIC ZIRCONIA SENSOR Technical Description The oxygen being produced by the concentrator flows out of the product tank and into the flowmeter. A small flow of oxygen produced by the unit is sent through a precision orifice to the oxygen sensor mounted on the printed circuit board. As the oxygen enters the sensor, it passes through a screen and contacts the sensing disk. Electric current flowing through a metal film resistor heats the disk in excess of 300° C. Oxygen molecules contact the electrode of the disk and pick-up extra electrons to become oxygen ions. These oxygen ions are attracted to the electrode on the bottom of the zirconia disk. Because of the crystal structure of the zirconia, only oxygen ions can pass through. When the oxygen ions reach the bottom electrode, the extra electrons are released from the oxygen ions and oxygen molecules return to the air. The number of electrons is directly related to the oxygen concentration. The electrons travel to the P.C. board where they are "counted" and the oxygen concentration "reading" is calculated. A microprocessor on the P.C. board contains software that interprets the signal being received from the sensor. It compares the signal to clinically acceptable limits. Signals outside of the clinically acceptable limits generate responses in the form of lights, audible indicators, and/or system shut-down. Operating Sequence Once the power switch has been turned ON (I), the SensO2 circuit will wait 5 minutes for the concentrator to begin producing clinically acceptable oxygen and the oxygen sensor to stabilize. The GREEN LIGHT will illuminate (indicating normal system operation) while the oxygen sensor is warming up. After 5 minutes, if the oxygen purity exceeds 85% ± 2% the GREEN LIGHT will continue to illuminate. If the oxygen level is not above 85% ± 2% after the first 5 minutes, the system will continue to monitor the O² and wait for a maximum of 30 minutes from start-up to reach 85% ± 2% before activating an alarm. Environmental factors such as low voltage, high altitude, or age of the machine will affect the time required to reach 85% ± 2%. If the oxygen level is not above 85% ± 2% within the first 30 minutes, the oxygen concentration alarm sequence will activate and the unit will shut down. When oxygen concentration is above 85% ± 2%, the sensor measures oxygen purity every 10 minutes. If a reading falls below 85% ± 2%, a YELLOW LIGHT will illuminate. If the oxygen purity falls below 73% ± 3% the RED LIGHT/Alarm/Shut-Down mode will activate.
