Installation instructions

WARNING
!
Voltage
In case of faults not-grounded, metalic assemblies may be energized
► When using metallic assemblies and installation equipment, comply with national grounding
regulations.
For a complete installation of a measuring point, proceed as follows:
1. Install a retractable or a flow assembly (if used) into the process.
2. Connect the water supply to the rinse connections (if you use an assembly with cleaning function).
3. Install and connect the oxygen sensor.
NOTICE
Installation errors
Cable breakage, loss of the sensor, unintended unscrewing of the membrane cap
► Do not install the sensor suspended from the cable.
► Screw the sensor into the assembly so that the cable is not twisted.
► Mounting or dismounting the sensor: hold the sensor body, only turn the threaded plug-in head
while screwing the sensor in or out of the assembly. Otherwise you could unscrew the sensor's
membrane cap. It will remain in the assembly resp. in the process then.
► Avoid exerting excessive tensile force on the cable (e.g. from jerky pulling).
► Select the installation location so that there is easy access for later calibration.
6.3

Post installation check

►Sensor and cable undamaged?
►Compliance with permissible sensor installation position?
►Is the sensor installed in an assembly and is not suspended from the cable?
►Avoid moisture by rain by putting the protective cap on the assembly?
