7. Using a suitable detergent-based leak detection fluid (e.g., Snoop
®
),
leak-check the threaded connections at the Pipe Adapter threads,
flange assembly, and the Sample, Vent, and Aspirator Drive Gas line
fittings on the HAG Probe and at the analyzer. Use the Aspirator Drive
Gas to perform the leak check, and observe the Aspirator Drive Gas
regulator for any noticeable pressure loss.
To avoid damaging the pressure transducer when leak-checking the
sample system, use a maximum of 10 PSIG.
For detailed information about leak-checking fittings, refer to “Sample
System Leak Check” in Chapter 3 of the analyzer manual.
8. If no leaks are present, secure the Heater Assembly on the top of the
HAG Probe.
a. Ensure the joining surfaces (heat transfer) of the Heater Block (un-
derside of the Heater Assembly and the top of the HAG Probe) are
free of debris. Use a non-abrasive cloth to gently clean the joining
surfaces, if necessary.
b. Place the Heater Assembly on the HAG Probe with the Junction
Box positioned on the side where the conduit ( North American
installations ) or cable ( European installations ) from the analyzer
has been installed.
c. Apply a high-temperature thread lubricant to the threads of the (4)
M6 x 60 mm screws (300-8741, Figure 3-1), install the screws, and
tighten them to secure the Heater Assembly to the HAG Probe.
The thread lubricant must not contain copper.
9. Complete the wiring, described under “Wiring Sample Probe Heaters
Controlled by Analyzer”, and then return to this procedure.
10. Take all necessary safety precautions and apply power to the ana-
lyzer, described under “Powering Up the Probe Heater Assembly and
Analyzer,” and then return to this procedure.
11. Install the Insulating Jacket on the HAG Probe to allow it to warm up
quickly.
The procedure is complete.
