SECTION 5
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 and internal valves from clogging when the machine
is reactivated.
Preparing for Long-Term Storage
1
With the carousel removed, remove and clean the nozzles. Be sure to store
nozzle parts in tubes that correctly indicate their 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 approved alcohol.
4
Flush at least 250 mL of approved alcohol through the reagent line by
priming all lines simultaneously. Leave the alcohol in the line.
NOTE:
When using potassium permanganate: flush the B-line with 250 mL of
water before flushing with alcohol.
CAUTION:
Leave alcohol 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 in Section 2.
