8-30 2000-OSM, F16. Select a harness assembly wire with the “R” label designation and overlap the “tinned” ends ofthis harness wire with one of the reference thermistor wires.7. Solder the wires using a 40 watt soldering iron and approved high temperature solder. Applysolder sparingly, allowing it to flow evenly. Do not overheat the solder or a high resistanceconnection could result.8. Repeat steps 6 and 7 for the remaining harness wire labeled “R” and reference thermistor wire.9. Repeat steps 6 through 8 for harness wires labeled “M” and the measurement wires.10. Slide heat shrink over each connection and shrink with a heat source.Leak Test1. Restore carrier to the analyzer and establish carrier flow to both the measurement and referenceports of the detector.2. Verify carrier and reference flow using a flow meter. Typically the flows should be 30 to 40cc perminute if packed columns are used; 10 to 15 cc per minute if 0.53 mm ID capillary columns areused, and 3 to 5 cc per minute if 0.32 mm ID capillary columns are used.3. Test for leaks around the detector thermistor gland nut with a nonconductive liquid leak detectionsolution. Correct all leaks before proceeding.4. Shut off the carrier supply to the analyzer.5. Gently remove any excess leak detection solution with a soft cloth or tissue and blow dry with 15psig clean dry air, helium or nitrogen.FPD REPAIRCAUTIONIt is the customer’s responsibility to ensure that the area is safe and and hazard-free, and will remain so the entire time the analyzer is open. This responsibilityincludes ensuring adequate ventilation in analyzer shelter and obtaining properwork permits, etc.See “AIR PURGING” in Section 4 for the X Purge override function. Do not performoverride until you have read Section 4 completely and you understand and canperform the procedure properly.
