3-14 | IPS-4 Dual Bench (UV / IR) Analyzer
Installing the Sample Probe/Sample Tap
If the Sample Probe is supplied by AMETEK, refer to the Final “As-Built”
drawings in the analyzer Documentation Package for installation informa-
tion. If the Sample Probe/Sample Tap is not supplied by AMETEK, refer to
the information and drawings shipped with the probe.
Installing and Connecting the Sample and Vent Lines
If an aspirator is used to drive the sample fluid (typical in gas ap-
plications), the Sample and Vent Lines must be minimum 3/8" O.D.
to avoid back pressure. This is of particular importance for the Vent
Lines.
For Vent Lines longer than 15 metres (50 feet), 1/2" O.D. tubing is
recommended.
This procedure applies to both unheated and heated Sample and Vent
Lines. Refer to Sample/Vent Line drawings (if lines supplied by AMETEK)
for additional information (see Final “As-Built” drawings in the analyzer
Documentation Package).
To avoid damaging the Sample or Vent Lines, use two wrenches to
ensure that the fitting body does not turn on the line.
Heated Lines only:
• Refer to Final “As-Built” Heated Sample/Vent Line Details drawings.
• When laying out the lines, ensure the ends with the electrical leads are
at the location of the external power supply.
• Install heat shrink around the Sample and Vent Line wiring and termi-
nate the Sample and Vent Line wiring to the external power source.
Refer to power termination instructions supplied with the Sample and
Vent Lines for details.
Ensure there is no power being supplied to the Sample and Vent Line
temperature-control zone circuits or external power source. Do not
apply power until the entire system has been installed, leak checked,
and the analyzer is ready for power-up.
