One-channel version
Two-channel version
• Depending on the ordered version, one or two collecting vessels (with or without level
measurement) are included in the scope of delivery.
• Level measurement is only possible for one channel.
• Only one collecting vessel can be mounted at the housing. The second is to be placed nearby the
analyser.
Adjusting the level measurement (one-channel version only)
Adjust the conductive level measurement due to the number of connected analysers.
1. In dependence of the application, mount the right adjusting pin or no adjusting pin (

and

7, position 2).
2. To receive an optimum sample volume, pull the marked pipe (position 3) downwards due to
your application (1, 2 or 3 analysers).
3.3 Installation instructions
To install the analyser at the intended location, proceed as follows:
1. Place the analyser in position and secure it to a wall using M6 screws.
For the installation dimensions, please see previous chapter.
2. Use a spirit level to check that the cabinet is hanging level. This is the only way to ensure that
any air bubbles that occur can escape from the optical cell.
3. Place the edge covers on the analyser edges (with GFK housing only).
4. Lay the drain pipe for the reaction products. Where possible, use fixed pipes (PVC or PE,
internal diameter ¾ " with 3% incline).
