Plumbing Connections

Sample inlet, sample return and drain connections are made
on the bottom side of the 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
⅜
the analyzer requires " OD (9.6 mm OD) flexible tubing. The
air purge inlets require ¼" OD tubing. The air purge supply
must be filtered externally and free of oil and any other
particulates.
The ⅜" (9.6 mm) DRAIN MUST BE
VENTED TO ATMOSPHERE. 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.
10 | Installation Environmental Considerations
The enclosure drain produces no waste
under normal use. However, in the event
of spills or leaks, some waste may be
produced.
NOTES:
The analyzer is shipped with all of the
internal tubing attached. Before
starting up the instrument, verify that the
