Section 5: Preventative Maintenance and Safety
5.2 Storing the Instrument
If the instrument will be inactive for more than one week, the recommendation is to perform the long-term
storage procedure. This will prevent nozzles from clogging when the instrument is reactivated.
Preparing for Long-Term Storage
1. With the carousel removed, remove and clean the nozzles. Store nozzle parts in tubes that are labeled
to indicate their correct position.
2. Unscrew the cap and remove the dip tube from the reagent bottles.
3. Place the end of the dip tube in a bottle of 50% DI water/50% methanol.
4. Flush at least 250 mL of 50% DI water/50% methanol through each reagent line by priming all lines
simultaneously. Leave the 50% DI water/50% methanol in the line.
CAUTION:
Leave 50% DI water/50% methanol in the reagent lines during storage. Allowing reagent lines to run
dry can damage the instrument.
5. Flush the bowl with 50% DI water/50% methanol.
6. Install nozzles stored in tubes in Step 1 to their original positions.
Preparing for Operation after Storage
Follow the Setup and Preparation for Operation instructions (Section 2).
