7) Slide the ferrule on the outlet end of the Filter so that the narrow side of the “cone”
faces up.
8) While gently but firmly pressing the filter housing toward the instrument, hand-tighten
the Filter nut (with the collar and ferrule inside) onto the
WATER IN bulkhead fitting.
9) Mark the surface of the Filter nut that is facing up with a pen or piece of tape to gauge
how much to tighten the nut.
10) While continuing to press the Filter toward the instrument, tighten the nut one and a
quarter full turns using the 9/16" wrench. Use the mark made on the nut in
step 9 to
determine when the full 1-1/4 turns are completed.The pressure fuses the collar, ferrule
and nut together and locks them on the Filter housing.
CAUTION:
Do not overtighten fittings, as leaks may result.
11) Connect the sample tubing to the inlet end of the Filter with the compression nut using
the 9/16" wrench.
12) Restore power and sample flow to the A643a TOC Analyzer and check for leaks.
Tighten fittings as necessary.
The inline Filter is now installed. The 15 micron strainer element inside the filter housing should
be checked yearly and replaced if sample flow appears to be restricted.

The Seiko Instruments Model DPU-414 thermal printer is integral to the Anatel A643a–P and
available as a desktop printer for local use with the Anatel A643a Analyzers. Refer to the Seiko
Operation Manual for detailed information on the DPU-414 Printer. The Manual is provided with
stand-alone printers and included in the Anatel A643a–P Installation Kits.
The appearance of a red stripe along the edges of the paper is an indication that the roll is
getting low. The printer’s red OFFLINE LED flashes when the paper roll runs out.
Note:
If paper has run out and the Anatel A643a has sent data to the printer, the green ONLINE LED
also flashes. The data are output with their time and date stamps when the new paper roll is
installed and the printer is placed back on-line.
