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
8.2.2. MAIN CIRCUIT BOARD INSTALLATION
Handle the new circuit board only by the edges to prevent an
electrostatic short.
1. Push the circuit board on to the four support tabs.
2. Firmly plug the connectors into the new circuit board so that the
connectors’ locking tabs lock against the circuit board.
3. Close the PSA module.
8.2.3. COMPRESSOR REMOVAL
To remove the compressor for exchange, follow the steps below:
1. Set the ON/OFF switch on both the modules to the OFF position, and
unplug the power cord.
2. Close the oxygen isolation ball valve.
3. Open the compressor module.
4. Remove the suction tube and the other end of the stainless-steel hose
that comes out from the compressor outlet.
5. Disconnect the two power cords from the terminal block and the two
capacitor wires.
6. Also disconnect the ground wire from the compressor.
