integrity of the tubing.
• Unused sample line ports may be blocked by
the user with a plug, or a particulate filter may
be installed to keep the system clean. If using
a plug, make sure the system vacuum level is
adjusted.
• If an analyzer is installed in the Vertex with
a Chemcassette tape, the optics may need
cleaning before activating a previously unused
point.

Figure 2-1. Sample Line Inlet Connections
To prepare for installation of sample lines, remove the
FEP Teflon tubing from the installation kit. The top of
the unit includes 25 connections:
• 24 Sample Inlets
• Exhaust Outlet (See
Pump Exhaust Line
Note:
Always perform a leak check after installing sample
lines. See Section 3.8 Leak Checking Sample Lines
for the leak check procedure.
Each inlet has a quick connect/disconnect fitting
with an internal O-ring and an external grab ring. To

install a tube into a sample line inlet, insert the tube
far enough into the fitting to ensure that the tube has
passed through both the external grab ring and the
internal O-ring and is firmly seated against the stop. The
insertion depth for a correctly installed sampling line is
1/2 in. to 5/8 in. (12 mm–16 mm). Verify the insertion
depth by holding the tube and marking with your thumb
where it emerges from the fitting. Remove the tube to
measure the insertion depth.
CAUTION
Improper installation of the tube into the con-
nector results in dilution of the sample.
2.4.3 Installing Sample Line Particulate
Filters
Attach a sample line filter to the sampling end of the
line for all locations.
CAUTION
Keep in mind that excess amounts of dirt in
the filters reduces the sample flow, raises
sample vacuum and may affect concentration
readings of the analyzer.

2.5 Installing Pump Exhaust Line

This section describes exhaust connections and
installation. The Vertex M System is equipped with a
vacuum pump that is located in the bottom of the Vertex
M System cabinet. The pump exhaust line connects
to the manufacturing facility central toxic exhaust
system.
