  • Page 88: Appendix E: Air Compressor

    Compressors start and stop automatically. Do not place hands or objects on or near any part of the compressor. QED Environmental Systems (QED) does not usually supply the air compressor. It is best to buy the compressor from a local supplier who provides service. Follow the instructions that accompany the compressor.

  • Page 89: Electrical Wiring For The Compressor

    AP-2 Manual Appendix E: Air Compressor Note: The information on compressors is for reciprocating piston compressors. A centrifugal compressor produces about twice the air of a piston compressor for the same horsepower. • As a general rule, a piston-type compressor should not start more than six times per hour. Also, a piston compressor should not operate more than 50% of the time.

  • Page 90: Motor Overload Protection

    This will help to extend air filter cartridge life. • Do not lubricate the compressed air coming out of the compressor. QED equipment is designed to run without the aid of lubricated air. The air filters are designed to remove oil from the compressed air.

  • Page 91: Maintenance

    AP-2 Manual Appendix E: Air Compressor Maintenance Although QED usually does not supply the compressor, this section is provided to help the operator. If the system receives clean, oil-free air from the compressor, maintenance will be significantly reduced. Inspection - Check for possible damage in transit. Almost all compressors are shipped with the flywheel unmounted.

  • Page 94: Appendix F: Pump Cycle Counter

    Appendix F: Pump Cycle Counter Introduction QED Environmental Systems (QED) Pump Cycle Counters (PCC) are air pulse detecting units that are placed in-line between a pump and its air supply. They require no external power source. A digital readout displays the number of times a pump cycles. PCCs consist of a magnet housing, an internally located magnet shuttle, and a digital display.

  • Page 95: Pump Cycle Counter Operation/Installation

    Appendix F: Pump Cycle Counter Pump Cycle Counter Operation/Installation When a pneumatically operated pump such as the QED AutoPump® has filled, it triggers itself “On”. This allows air to flow to the pump until a certain volume of fluid has discharged. The air stops; the pump fills; then the cycle continues to repeat.
