7. Use a 1/4" wrench to loosen the Valco nut from the outlet bulkhead
and remove the tubing. Disconnect the other end of the tubing from
the rubber tubing on the sample inlet system. This tubing will be
needed for on-line sampling; place the tubing in a secure
location.
8. Locate the two 1/16" OD Teflon lines with Valco nuts and ferrules in
the accessories kit that came with the analyzer.
9. Connect one of the 1/16" OD Teflon lines to the OUTLET bulkhead
fitting and tighten finger-tight. Use a 1/4" wrench to secure the nut 1/8
of a turn past finger-tight. Do not over tighten, the tubing will
collapse and prevent flow!
10. Connect the other 1/16" OD Teflon lines to the INLET bulkhead fitting
and tighten finger-tight. Use a 1/4" wrench to secure the nut 1/8 of a
turn past finger-tight. Do not overtighten; the tubing will collapse
and prevent flow!
11. Place the Teflon tube from the OUTLET in a suitable waste
container.
WARNING
The waste stream from the analyzer is acidic and must be disposed of according
to local regulations.
12. Place the Teflon tube from the INLET in the sample container making
sure that the end of the tubing is immersed in the sample.
13. Follow the instructions in the Operations Chapter to select the Grab
Sample Mode and proceed with measurements.
If using the analyzer for a large number of grab samples, consider using the
Autosampler system, available from Ionics Instruments.
