Hardware Installation
10. Using a 1/8 in. to 1/16 in. reducer fitting, connect the other end of this tube to the exhaust of the
TCD.
11. Install the 31 in. long tube (part number 004-03388-16, Hastelloy-C tubing 1/16 in. diameter ×
31 in. long) from the right side of the TEE to the hexagonal fitting located above the exhaust
ports where the 1/8 in. tube was removed.
A 1/8 in. to 1/16 in. reducer fitting is required.
12. Using the new screw (part number 004-28310-01, 6-32 × 1.5 Pan Head Phillips), attach the
TEE as shown in the previous illustration.
13. Attach the new reducing union to the end of the Mass Spectrometer heated hose fitting. Use
the ferrules included with the reducing fitting.
14. Pass the Mass Spectrometer hose through the side panel cover plate. The black plastic
clamps above and below the Mass Spectrometer hose can be adjusted to prevent the Mass
Spectrometer hose from being pulled out of the heated zone. The insulation rings may be
used to prevent damage to the Mass Spectrometer hose insulation.
15. Re-attach the side panel cover plate, with the Mass Spectrometer hose passing through into
the heated zone.
