Attaching chambers and extensions manifolds

One cable and tube bundle (part number 9982-056) is used for each chamber and extension manifold.

Chamber cables and tubes

Chambers attach to the LI-8250 Multiplexer and the 8250-01 Extension Manifold with the tube and cable bundle (part number 9982-056).

1. For each chamber, connect the thermistor cable on the chamber to one of the SENSOR ports on the chamber.

2. Attach the tube quick-connect fittings and cable to the LI-8250 Multiplexer connection panel.

   Align the key with the slot and then tighten until snug. Press and turn a little more until the connector is fully seated.

3. Attach the tube quick-connect fittings and the cable to the chamber.

   Be sure that tube and cable connections for each chamber and each extension manifold are made to the same port.

8250-01 Extension Manifold cable and tubes

Extension manifolds connect to the multiplexer with the cable and tube bundle (part number 9982-056). The multiplexer provides power to the extension manifold and to any Long-Term Chambers connected to the extension manifold (unless you are using the flask sampling kit). The multiplexer and extension manifold use quick-connect fittings for air tubes and connectors for the cables.

1. Attach the quick-connect fittings and the cable connector to the connection panel on the LI-8250.

   Be sure that tube and cable connections for an extension manifold are made to the same port.

2. Attach the quick-connect fittings and cable to the Extension Manifold connection panel.

   Align the key with the slot and then tighten until snug. Press and turn a little more until the connector is fully seated.
