UV Lamp Maintenance

Note:

Replacement Kit: P/N FG6002601

The ultraviolet (UV) lamp in the A643a TOC Analyzer requires periodic replacement to ensure
accurate analyses. The Anatel A643a logs UV lamp usage based on its total hours of
operation. Anatel recommends replacement of the UV lamp every six months to ensure
uninterupted operation due to lamp degradation.

CAUTION:

DO NOT touch the glass surface of the new UV Lamp. A lamp contaminated with fingerprints
can be cleaned with isopropyl alcohol and a lint-free cloth.
