SU inlet filters
The SU inlet filter should be checked and cleaned occasionally (every 3 months is recommended).
When unscrewing the filter mesh nut some content from the system will be spilled.
Check and clean the filter by unscrewing the filter mesh mounting nuts.
Rinse in a bucket to get foreign objects out of the mesh.
If the mesh is teared apart, then install a new mesh.
Mount the cleaned filter mesh and check for any leaks.

Calibration
5.3.1.
pH Sensor Calibration
Calibration must be performed with buffer solution pH7 and pH4. The selected pH buffer solutions must be with an
accuracy of +/- 0.01pH. Fresh or newly prepared solutions must be used for each calibration.
Tools needed for pH calibration:
Allen key size 5
Distilled water
pH Buffer solution 4
pH Buffer solution 7
Switch off the power for the SU pump (if applicable), close all isolation valves for the WMS system and drain the
measurement chamber before starting the pH calibration.
Do not let the pH sensor get dry. If the sensor is dry, it must first be re-conditioned for several hours (>12h) in pH4 buffer.
Remove the pH sensor from the measuring chamber by loosening the four M6 bolts holding the pH sensor in place.
Insert the sensor in a container with distilled water to prevent the sensor from getting dry.
pH calibration
To perform the pH calibration, go to the pH Calibration menu 6-2*. The following illustrations shows LCP when
performing the pH calibration.
