Installing and Connecting the Sample and Vent Lines
The Sample and Vent Lines can be supplied by AMETEK or the customer.
Heated lines, which are not supplied by AMETEK, can only be monitored
by the analyzer; they cannot be controlled.
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 appropriate customer-specific Sample/Vent Line Installa-
tion drawings (if lines supplied by AMETEK) for additional information.
These drawings are located in the “Supplemental Information” tab of this
manual and the Documentation Package shipped with the analyzer.
To avoid damaging the Sample or Vent Lines, use two wrenches to
ensure that the fitting body does not turn on the Teflon line.
Heated Lines only:
• Refer to customer-specific Sample/Vent Line 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.
