instrument. The sample inlet and sample return fittings on the bottom of analyzer require
¼" OD (6 mm OD) flexible tubing. The drain fitting at the bottom of the analyzer requires
⅜

NOTES:
1. It is recommended that you install an external sample shut off valve
to allow control while accessing or service to the sample chamber.
2. Air purging of upper and lower enclosures is recommended.
3. Each analyzer MUST have its own drain tube vented to atmosphere.
4. The installation of a power circuit breaker is highly recommended.

. The sample
drain contains analysis wastes, which include both sample and chemical
reagents. Please check with local authorities concerning proper disposal of
waste from this product.

The enclosure drain produces no waste under normal use. However, in the
event of spills or leaks, some waste may be produced.
The analyzer is shipped with all of the internal tubing attached. Before starting
up the instrument, verify that the tubing lines are secured.
