4. Mechanical installation
Refer to Figures One or Two for this procedure. Reference will depend on orientation
of tubing from regulator.)
4.1. Remove the outlet PFA tube connector from the pressure regulator of the analyzer.
4.2. Detach the regulator from the analyzer by removing the two screws on the bottom of
the mounting bracket making sure not to lose the fiber spacers.
4.3. Remove the elbow from the outlet side of the regulator and clean the port and
connector threads of any Teflon
®
tape remains. Reapply 4 wraps of Teflon tape to
the elbow and screw the fitting back into the regulator ending with the tube fitting
pointing down as shown.
4.4. Reinstall the regulator to the analyzer with the two screws making sure to use the
fiber spacers.
4.5. Remove the PFA tube from the inlet of the sampling block.
4.6. Position the flow switch and secure the end of the stainless steel U-tube to the
regulator outlet. Wires must point up to have a calibrated normally open switch.
4.7. Secure the PFA tube from the outlet of the switch to the inlet of the sampling block.
4.8. Connect the wires from the flow switch to the Binary Input Module, polarity not
important to the binary module.
4.9. Route the electrical cable as desired and plug the end into the AUX PORT on the
opposite side of the instrument.
