Installation with chain retainer
The chain retainer is particularly suitable for applications that require a sufficient distance
between the mounting location and the edge of the aeration basin. As the assembly is freely
suspended, any vibration of the upright post is practically ruled out.
The swinging movement of the chain retainer enhances the self-cleaning effect of the
optical window.

The cleaning unit is particularly suitable for clear water and media containing fats/oils that
tend to cause heavy buildup.
Mount the cleaning unit as follows:
1. Fit the cleaning unit onto the sensor as far as it will go.
2. Locate the two LEDs (they are installed at an angle and have a bright enclosure).
3. Position the cleaning unit in such a way that the nozzle is located at the side of the two
LEDs (see å 10).
4. Fix the cleaning unit in place with the securing screw (max. torque: 0.5 Nm
(0.37 lbf ft)).
5. Insert the compressed air hose of the compressor into the hose connection.

3.3.2 Pipe installation
a0013009
Fig. 12: Installation with retractable assembly
Arrow 1 shows the flow direction.
The installation angle must not exceed 90°.
The recommended installation angle is 75°.
The optical windows of the sensor have to be aligned
parallel to the flow direction ( = 90°) or face the
flow direction ( < 90°).
For manual insertion/retraction of the assembly the
medium pressure may not exceed 2 bar (29 psi).
a0015169
Fig. 13: Installation with flow assembly CYA251
The installation angle is 90°.
Turbidity measurement < 200 FNU will result in
erroneous measuring results due to backscattering of
pipe wall.
