Preparing for Maintenance
Before routine maintenance procedures, the GC must be made ready. This process can
include:
• Setting low temperatures to avoid burns and other injuries
• Setting reduced flows to avoid safety hazards and to prevent damage to the instrument
• Turning off the GC and disconnecting the GC from power
• Venting a mass selective detector (MSD)
• Making other settings to prevent damage to the instrument (electronics, columns, and so
forth) or to connected instruments (MSD)
To put the GC in a general standby state suitable for most maintenance, open the browser
interface. From the browser interface, go to Maintenance > Instrument > Perform Maintenance
> Maintenance Mode > Start Maintenance. Follow the prompts. To exit maintenance mode
and restore the previous GC settings, click Finished.
If you turned off the GC or changed other settings, return to the Maintenance Mode screen as
needed. Note that the Maintenance Mode ends when the GC is turned off.
For automated maintenance procedures available through the GC, the GC will make the
instrument safe to work on and walk you through the steps required to replace the part
selected.
If you choose to perform maintenance without using the GC's built-in features, first cool all
heated zones in the instrument, including auxiliary heaters or other heated devices you might
contact during maintenance. Then turn off the GC and unplug the power cord.
