12. Locate the ¼ inch low pressure output fitting on the installed pressure regulator on the
calibration gas cylinder.
13. Measure and cut the 1/16 inch 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 analyzer 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 nut down onto the ferrule, screw into the port and tighten.
20. Leak test all gas connections when completed.

Vent lines connections
The following procedure provides general steps for connecting the external vent lines from the
respective output ports on the feed-through assembly. When the analyzer is installed in the
environmental enclosure, the sample vent line must vent outside of the enclosure. Other installations
may only require short lines. Follow the requirements of national and local codes during installation.
Materials:
Four 1/16 inch ferrules and nuts
Four 1/16 inch SST vent tubing (supplied with analyzer) or
Four 1/16 inch SST tubing (amount to be determined by the technician based on the distance
from the analyzer to the external vent location)
To connect vent lines:
1.
Locate the gauge port vent (GPV), sample vent (SV)), column vent 1 (CV1) and column vent 2
(CV2) ports on the feed-through assembly (see
). Remove the sealing screws for
the vent ports.
2.
Using the supplied vent tubing (if sufficient length) and ferrule, place the nut and ferrule onto
the short end of the bent tubing. Insert the tubing and ferrule into one of the vent ports, with
the open end of the tubing pointing down. Move the nut down onto the ferrule, screw into the
port and tighten.
3.
If the vent tubing is not of sufficient length, measure and cut new tubing (not supplied). Make
the necessary bends to install the tubing. Place the nut and ferrule onto the corresponding end
of the tubing. Insert the tubing and ferrule into one of the vent ports, being careful to keep
tubing horizontal, with the open end of the tubing pointing down. Move the nut down onto the
ferrule, screw into the port and tighten.
4.
Repeat step 2 or 3 for all other vents listed in step 1.
NOTICE – Equipment damage.
All four vents must be open to atmospheric pressure
without back pressure. Position the vent tubing in a downward direction so that moisture
does not accumulate in the tubing.
