7. The instrument has specific power supply requirements. See the table later in
this chapter for a complete listing of power requirements.
Installing the Instrument—Plumbing
SmartTrak instruments are supplied with compression, VCO
®
, VCR
®
, or female NPT
process connections. To ensure a successful installation, inlet and outlet tubing 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 SmartTrak. 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.
