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.
NOTE
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.
CAUTION
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
WARNING
apply power until the entire system has been installed, leak checked,
and the analyzer is ready for power-up.
