Cleaning And Decontamination - Hach POLYMETRON 8810 Basis-Benutzerhandbuch

• Check the system is running smoothly. Calibrate if necessary

8.3 Cleaning and decontamination

The analyzer does not normally require any cleaning or decontamination.
If needed, clean the exterior of the instrument with a moist cloth and a mild soap solution. Never use
cleaning agents such as turpentine, acetone or similar products to clean the instrument, including the
display and any accessories.
8.4 Shutdown
Stopping the measurement cycle
Select STOP in the main menu and press Enter. The message stopped is displayed.
Short shutdown (e.g. weekend)
Select STAND BY in the main menu and press Enter to put the system in a defined standby
condition. The measurement chamber is drained, rinsed, and refilled with rinse water.
Prolonged shutdown
If the system is shut down for a long period of time the electrodes must be cleaned and the
measurement chamber rinsed. It is preferable to then remove the electrodes and store them in a
buffer solution until the system is restarted. Under no condition must the electrodes be left in an
empty measurement chamber as this will cause them to dry out and become damaged. Finally, turn
the power off.
