5) Install the reducer into the carrier gas regulator.
6) Insert the tube with the ferrule into the reducer/pressure regulator output fitting.
Move the nut down onto the ferrule, screw onto fitting, tighten.
7) Carrier gas pressure should be set at 90 PSIG.
8) Locate the carrier gas input (CAR) on the NGC feed-through assembly and
remove the sealing screw.
9) Purge the air from the transport tubing by opening the shut-off valve located on
the regulator.
10) Insert the tube with the ferrule into the carrier gas input port (CAR) on the feed-
through assembly. Move the Valco nut down onto the ferrule, screw into the port
and tighten.
11) Determine the input port for the calibration gas (typically S4) on the NGC feed-
through assembly (see
12) Locate the ¼" low pressure output fitting on the installed pressure regulator on
the calibration gas bottle.
13) Measure and cut the 1/16" SST tubing to the required length.
14) Make the necessary bends in the tubing to ease the installation of the ferrule and
tubing into the NGC and pressure regulator.
15) Install the reducer into the calibration gas regulator, if required.
16) Insert the tube with the ferrule into the reducer/pressure regulator output fitting.
Move the nut down onto the ferrule, screw onto the fitting and tighten.
17) Calibration gas pressure should be set at 15 PSIG.
18) Purge the air from the transport tubing by opening the shut-off valve located on
the regulator.
19) Insert the tube with the ferrule into the calibration gas input port (S4) on the feed-
through assembly. Move the Valco nut down onto the ferrule, screw into the port
and tighten.

Tube, ferrule and nut should always enter the connection at a
right angle.
Leave the sealing screw in any unused ports. If unused
stream ports are not sealed, moisture can enter the manifold
which can damage the instrument and void warranty.
Be sure to follow the requirements of the national and local
codes when performing this purge.
Figure 2-43) and remove the sealing screw.
Be sure to follow the requirements of national and local codes
when performing this purge.
Leak test all gas connections when completed.
