PREVENTIVE MAINTENANCE AND SAFETY
5.2 Storing the Instrument
If the instrument is inactive for more than one week, you may want to perform the long-term
storage procedure. This will prevent nozzles from clogging when the machine is reactivated.
Preparing for Long-Term Storage
1 With the carousel removed, remove and clean the nozzles. Store parts in
tubes that are labeled to indicate their correct position.
2 Unscrew the cap and remove the dip tube from the bottles.
3 Place the end of the dip tube in a bottle of methanol.
4 Flush at least 250 mL of methanol through each reagent line by priming all
lines simultaneously. Leave the alcohol in the line.
CAUTION:
Leave methanol in the reagent lines during storage. Allowing reagent lines to
run dry can damage the instrument.
CAUTION:
Do not subject the instrument to freezing temperatures. Freezing of aqueous
fluids in the lines may cause damage to the instrument.
5 Flush the bowl with water.
6 Return nozzles to their original positions.
Preparing for Operation after Storage
Follow the Setup and Preparation for Operation instructions (Section 2).
