Anatel Operator Manual
2.3.1.3 Anatel A643a–P Analyzer
The ambient air temperature should not exceed 35°C (95°F) wherever the portable Anatel
A643a–P Analyzer is positioned. Orientation also is important when locating the instrument. It
must be maintained in an upright position with the integral Controller’s panel facing upwards.
This precaution assures that the measurement cell is flushed completely between analysis
cycles, thereby ensuring reliable and accurate analysis results.
The following plumbing, communications and power connections are identical for the Anatel
A643a–S and Anatel A643a–P Analyzers.
The terms “Anatel A643a” and “Analyzer” in th following instructions refer generally to all
A643a TOC Analyzer models.
2.3.2 Plumbing Connections
Sample connections are made through a 1/4” inlet (WATER IN) and a 1/8” outlet (WATER OUT)
316 stainless steel compression fitting located at the Water I/O end of the Analyzer enclosure.
The sample inlet is fitted with a prefilter to minimize the potential for contamination. Plumbing
the Analyzer consists of making these two connections and optionally installing an upstream
isolation valve to permit control of sample flow to the instrument.
