Maintenance
6.7 Shut the analyzer down
No special measures are necessary for taking out of operation for a
short period (up to a week in frost-free ambient conditions).
Important note: If the power supply to the controller is interrupted,
frost damage may occur. Make sure that the instrument and tubing
cannot freeze.
1. Interrupt the measurement and switch the instrument to the
service state (MAINTENANCE>TEST/MAINT.>SERVICE
MODE).
2. Disconnect the AMTAX sc from the controller.
6.7.1 Shut the analyzer down for an extended period
Important note: Always wear safety equipment when
handling chemicals.
Use the following procedure if the instrument is to be taken out of
operation for an extended period or in the case of frost.
1. Immerse the tubing for reagent, cleaning and both standard
solutions in distilled water.
2. On the controller TEST/MAINT menu, start a cleaning cycle
with distilled water using the FLUSHING function.
3. Clean the canister lid with distilled water.
4. Take the tubing out of the water and start the FLUSHING
function to pump the tubing and the analysis instrument empty.
5. Wipe the canister lids dry and seal the canisters with the
corresponding lids ( Table 3, page 30 ).
6. Remove the canisters and store them in a frost-free place and
in accordance with local regulations.
7. Remove power from the instrument and data network.
8. Pull the electrode connector off the analyzer panel.

The electrode body is very hot (up to 60 °C [140 °F]). Let the
enclosure cool down before touching.
9. Pull the electrode carefully and straight out of the electrode
body ( section 3.7.1, page 31 ).
10. Drain the electrode body as per the applicable regulations.
11. Rinse the electrode body and the electrode with distilled water.
12. Insert the electrode in the rinsed enclosure and then insert the
electrode body in the electrode cell on the AMTAX sc.
13. Reconnect the electrode cable to the analyzer panel.
