5-22 Maintenance Procedures
To remove the sampling cone assembly from the source
1. Close the source isolation valve (see page 5-15).
2. Grasp the cone gas nozzle handle, and use it to rotate the sampling cone
assembly 90 degrees, moving the handle from the vertical to the
horizontal position.
Warning: The source components can be contaminated with
biohazardous and/or toxic materials. Always wear
chemical-resistant, powder-free gloves while performing this
procedure.
Warning: To avoid electric shock, ensure that the instrument is in
Standby mode before commencing this procedure.
Warning: To avoid puncture wounds, take great care while working with
the source enclosure open if one or both of these conditions apply:
• An ESI probe is fitted (the probe tip is sharp).
• A corona pin is fitted (the pin tip is sharp).
Warning: The source can be hot. To avoid burn injuries, take great care
while working with the source enclosure open.
