5-112 Maintenance Procedures
5. Using a long "finger tight" fitting, connect orange, 1/16-inch, 680-mm,
PEEK tubing from port 4 of the sample selector valve, through tubing
guide A and into vial A.
Requirement: As the tubing emerges from the tubing guide, thread the
long "finger tight" fitting over it, push the tubing through the right-hand
hole, to the bottom of the vial and tighten the fitting.
Tips: Follow these suggestions if you find threading the tubes through
the guides difficult:
• Thread the tubes upward from the bottom hole.
• Using needle-nose pliers, make a 20° bend, 10 mm from the end of
the tubing. Then rotate the tubing, as necessary, as you thread it
through the guide.
6. Repeat this procedure for port 5 to vial B and port 6 to vial C.
