Tubing Connections
Vacuum Connector
The vacuum connection at the bottom of the device (next to the electrical
connections) should be connected to a vacuum pump or central building
vacuum supply capable of providing 15 inHg (38 cmHg) of vacuum at the
rated flow rate of 0.1 or 1.0 cfm (2.8 or 28.3 L/min).

The sampling inlet at the top of the device can be configured with a
barbed inlet (default) for sampling or connection to a sample tube. The
barbed fitting can also be replaced with a screw-on isokinetic sampling
inlet configured based on the sample flow as shown below. See the table
of optional accessories in Chapter 1 for more information.
