Notes.
1.
The de-bubbler
MUST
be mounted vertically with the flow upwards.
2.
Degassing of the sample causes very erratic readings. To prevent degassing, do not exceed stated distance.
3.
Adjust the flowrate as required to prevent blockages in the pipework and/or sediment build-up in the flowcell.
4.
Install flow regulating valves and a flow indicator to simplify maintenance and ensure consistent performance.
These items are not supplied with the AV400 Series UV Dissolved Organics Monitor system.
