See Figure 6.9.
1. Turn off gas supplies to analyser
2. Drain water out of bubbler tube by unscrewing and removing drain plug.
3. Disconnect vent/drain pipe if fitted.
4. Open door (2) by turning Dzus fastener (12) and remove door.
5. Unscrew and remove 2 X M6 slot head screws in base (4)

5.4.2.2 Setting Sample Flowrate
1. Measure total sample gas flow rate out of drain / vent.
The flow meter used should have minimum back pressure.
2. Open valve slowly until a total flow rate of 200ml/min ±20ml/min is measured.
3. Adjust the sample dip leg (35) by slackening the coupling nut (33) and adjust until the flow
from the bypass dip tube just stops.
4. Re-tighten coupling nut (33).
