SECTION 1—IMPORTANT SAFEGUARDS SECTION 1—IMPORTANT SAFEGUARDS WARNING IMPORTANT SAFEGUARDS contains important information for the safe operation and use of this product. DO NOT use this product or any available optional equipment without first completely reading and understanding these instructions and any additional instructional material such as Owner’s Manuals, Service Manuals or Instruction Sheets supplied with this product or optional equipment.
SECTION 1—IMPORTANT SAFEGUARDS Maintenance The Platinum Oxygen Concentrator was specifically designed to minimize routine preventive maintenance. Only professionals of the healthcare field or persons fully conversant with this process, such as authorized or factory trained personnel, should perform preventive maintenance or performance adjustments on the oxygen concentrator. Radio Frequency Interference Most electronic equipment is influenced by Radio Frequency Interference (RFI).
SECTION 2—INSTALLATION/SEQUENCE OF OPERATION SECTION 2—INSTALLATION/ SEQUENCE OF OPERATION Installation/Verification of Battery Free Power Loss Alarm When your new Platinum 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 four to five seconds to charge the Battery Free Power Loss Alarm.
SECTION 2—INSTALLATION/SEQUENCE OF OPERATION 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. (144.79 kPa) for Platinum 5 and XL; 25 p.s.i. (172.36) for Platinum 10. The time between cycles is dependent on altitude, flow rate and internal environmental factors. A P.E. valve opens just prior to the shift of the 4-way valve.
SECTION 2—INSTALLATION/SEQUENCE OF OPERATION After five 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 five 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%.
