should be clean prior to plumbing the instrument into the system. The shipping caps
covering the inlet/outlet fittings should not be removed until immediately before
installation.
Follow the installation instructions that are applicable to your instrument’s process
connection. Ensure that the tubing is free from burrs or sharp rims that may result
from cutting.
CAUTION: Before use, all plumbing should be checked carefully for leaks,
especially at the connecting fittings. All instruments are leak-tested prior to
shipping. It is not a requirement to leak test your instrument. Do not use liquid
leak detectors such as Snoop
®
to search for leaks inside or outside the Smart-
Trak 2. Instead, monitor pressure decay.
Compression Fittings
1.
Position the instrument with the
flow direction arrow pointing in the
direction of flow.
2.
Verify the position of the front and
back ferrule. Insert the tubing into
the fitting. Be sure that the tubing rests firmly on the shoulder of the fitting
and that the nut is finger-tight. Scribe the nut at the six o’clock position.
3.
While holding the fitting body steady with a backup wrench, tighten the nut
1-1/4 turns, watching the scribe mark make one complete revolution and
continue to the nine o’clock position. For 1/16-inch, 1/8-inch and 3/16-inch
(2, 3 and 4 mm) sizes, tighten only 3/4 turns from finger-tight.
Do not over-
tighten!
4.
If you use flexible tubing (Example: Polyflow) use an “Insert” (see
www.swagelok.com)
5.
Check the system’s entire flow path thoroughly for leaks.
Do not use liquid
leak detectors.
Instead, monitor pressure decay. Exposing the instrument to
leak detector fluid may cause damage.
VCO Fittings
1.
Position the instrument with the flow direction arrow pointing in the
direction of flow.
2.
Tighten the nut finger-tight, and then 1/8 turn tighter with a wrench.
Do not
over-tighten!
