1.
Follow the plumbing flow schematic shown in Figure 2.5.
2.
Leak test by connecting together the sample 'IN' and 'OUT' gas
connections and connect a water manometer to them. Pressurise the
system to approx. 500mm water gauge and leave to stabilise. No
change in manometer level should be detected once the reading has
stabilised.
3.
If a leak exists, check connections using a soap solution (max.
internal pressure 10psig). This testing should also include the oxygen
cell and its window.
4.
Rectify leaks and re-check.
