procedures to perform on the instrument.

you complete the installation of the instrument.
Once the instrument has been successfully installed, the Skip installation wizard on device startup
checkbox should be checked to ensure a normal startup from there onwards.
Maintenance
It is recommended to use the maintenance wizards for maintenance of the instrument. Simply follow the
on-screen instructions available for each of the options.

refilling the existing cartridge, follow the instructions given in

To ensure the performance and reliability of the instrument, it is strongly
recommended to only use the silicon antifoam supplied by Hach Lange (part number

regularly to restore its original sensitivity. A clear sign that a sensor maintenance is
required is when measurements are noticeably less stable than usual.
