6-9 HOW TO CLEAN THE A10 TOC MONITORING DEVICE
The A10 TOC Monitoring Device may need to be cleaned sometimes. This cleaning does not involve any chemical
reagents. This cleaning is initiated with the Milli-Q software and is simple to perform.
HOW LONG DOES THE A10 CLEANING TAKE ?
The A10 Cleaning takes 60 minutes to complete. The LCD will show a countdown timer indicating the
remaining time until the A10 Cleaning is finished.
WHY WOULD I NEED TO DO AN A10 CLEANING ?
The A10 Cleaning is recommended when:
1. the Q-Gard and Quantum have been replaced (see the next question below).
2. the displayed TOC values are fluctuating.
3. the displayed TOC values are higher then normally seen.
4. the Milli-Q has been in STANDBY Mode or powered off for more than 12 hours.
WOULD AN A10 CLEANING EVER HAPPEN AUTOMATICALLY ?
An A10 Cleaning will occur automatically after the Q-Gard Pack and Quantum Cartridge are exchanged.
Normally, a 5 minute AIR PURGE Mode is started after the Quantum Cartridge is replaced. When the AIR PURGE
is finished, the 60 minute A10 CLEANING Mode is started.
See Section 4-7 for more information about the AIR PURGE and the automatic A10 CLEANING Mode.
