Section 2: Setup and Preparation for Operation
The Clean Cycle
Two Clean Cycles are available from the Main menu:
System Clean – cleans nozzle ABCE by purging it with SS-051E (Alcohol Wash) and cleans nozzle DF by
purging it with SS-051F (Acid Alcohol Wash) while cycle progress is displayed on the screen. The cycle
may be stopped at any time during the process.
NOTE: Pressing Standby/Ready performs a System Clean Cycle before the instrument goes on standby.
Carousel Clean – cleans the carousel and nozzle DF by purging with SS-051F (Acid Alcohol Wash). This
clean cycle is of sufficient length to clean both nozzle DF and the carousel. The cycle may be stopped at
any time during the process.
To run either Clean Cycle:
1. Place an empty carousel in the instrument and close the lid.
CAUTION:
Never place any carousel loaded with specimens in the instrument for a Clean Cycle (including
placing the instrument in standby mode). Specimens will be damaged if they contact reagents
sprayed from the nozzles when pressing Clean or Standby.
2. Press Clean.
NOTE: Pressing Stop during the Clean Cycle causes the Incomplete Clean message to be displayed.
Press Clean to complete the interrupted cycle.
3. Open the lid and remove the carousel when the Clean Cycle is complete.
4. Spray the interior of the bowl with 70 to 100% methanol, ethanol or SS-029 nozzle cleaning solution.
Wipe the stainer bowl dry with paper towels.
NOTE: Perform the Storing the Instrument procedure (Section 5.2), if the instrument will remain idle for
more than one week.
NOTE: At the end of a Clean Cycle, nozzle DF is filled with SS-051F (Acid Alcohol Wash) and nozzle
ABCE is filled with SS-051E (Alcohol Wash), which remains in the nozzles. These are primed out of the
nozzles during the first steps of a stain cycle.
