Gas Unit Disassembly
The disassembly of the gas unit is necessary for the replacement of the pneumatic block filter, the nafion
tubing, and the absorber.
Caution:
Observe precautions for handling electrostatic-sensitive devices!
Note:
• Never touch electrostatic-sensitive electronic components without following proper anti-static
procedures, including the use of an ESD wrist band and mat. An electrostatic discharge from your
fingers can permanently damage electronic components.
• All static-sensitive electronic components are packaged in static-shielding bags. Retain the bag for
repackaging the component, should you need to store it or return it to Spacelabs Healthcare for any
reason.
