TROUBLESHOOTING CHART
The chart on the following pages is a guide for troubleshooting the AirSep Centrox
Oxygen Concentrator.
The interior of the oxygen concentrator contains electrical parts
that can produce an electrical hazard if not handled properly. To
prevent electrical shock, use extreme care when you service the
system.
The Printed Circuit Boards (PCBs) contain components that are
sensitive to electrostatic discharge (ESD) and can be damaged if
not handled properly. As when handling any ESD-sensitive PCB,
observe standard ESD safety procedures. These procedures
include the following:
■ Handle the PCB only by the edges
■ Work on a grounded ESD mat
■ Wear a grounded wrist strap
■ Store PCBs only in anti-static bag
