The filter unit is attached to the tubing as follows, see Fig.2.9.

2.3.3 Connecting a Tracer Gas Supply
Tracer gases for use with the 1303 must be supplied from a pressurized
cylinder fitted with a suitable pressure-regulator. The regulator ensures
that the tracer-gas pressure is constant.
Warning! Do not attempt to connect a tracer-gas cylinder without a
pressure-regulator directly to the 1303. Doing this can damage the
1303’s internal airways.
