    & C Chapter 2. ARNINGS AUTIONS Warnings and cautions are used throughout this manual to identify possible safety hazards, conditions that may result in equipment or property damage, and important information that must be considered when performing service and testing procedures on the EverFlo Oxygen Concentrator. Please read this section carefully before servicing the EverFlo Oxygen Concentrator.

  • Page 7: Cautions

    WARNINGS • Avoid handling the molecular sieve material. Respironics recommends the return of the sieve canister assembly to Respironics for any service that involves sieve disposal. • Use extreme caution when handling the compressor capacitor as it holds an electrical charge until is it properly discharged.

    Chapter 4. HEORY OF PERATION This section describes the theory of operation for the EverFlo Oxygen Concentrator. PNEUMATIC OPERATION Refer to Figure 4-1 while reading the following discussion. The room air is drawn into the unit through the air inlet filter by the compressor. The compressed air is routed to the sieve beds through an electronically controlled Solenoid Valve Assembly.

  • Page 12: Electrical Operation

    ELECTRICAL OPERATION The EverFlo Concentrator is a medical device, which produces concentrated oxygen from room air for delivery to a patient. It uses a molecular sieve and a pressure swing adsorption process to concentrate oxygen from air. The device consists of filters, a compressor, a sieve canister module, a set of valves, a microprocessor-based electronic controller PCA, a flow meter and a cooling fan –...
  • Page 13 4.3.1 POWER The AC mains power, via the line cord, is brought onto the PCA and the “switched” AC is distributed to the Compressor, the Cooling Fan and to the AC to DC conversion module. The DC voltages that are generated are used to power the remaining circuitry.
