Table 18 Fixed and Mobile Seal Replacement O-Rings
Changing the O-Rings and Filter Disk in the
TD Mobile Seal
Change the tube-seal o-rings (P/N 0497-0434 and L1003006)
whenever there is evidence of repeated tube leaks. The mobile
assembly also contains a filter disk to prevent packing, glass wool
fibers and other waste from the sample tube material from entering
the pneumatic system.
Replace the filter disk (P/N L100-3029) when it has been damaged,
when it appears discolored, or when the o-ring (P/N L100-3006) is
replaced.
To change the mobile seal o-ring:
1. Make certain that the TD is in Standby. Turn off the TD
and disconnect it from the AC line power.
2. If necessary, allow the instrument to cool.
