5.3 Clean Sample Rotor Valve (SRV)
Clean the sample rotor valve once a month, or every 2500 samples, and reset the counter as
described below.
NOTE: After every 2500 cycles or a month after the previous cleaning, the
message "Clean the SRV." will be displayed at power ON.
WARNING! The SRV should be considered potentially biohazardous. Do not
handle the SRV without proper protective equipment. Wear rubber
gloves when cleaning. Wash your hands with an antiseptic solution
after completing the procedure.
CAUTION: If reagent spills on painted surfaces of the instrument, immediately
wipe it up with a damp tissue.
(1) Run a quality control prior to the SRV cleaning. The data will be used for the data
verification in step (17).
(2) Turn OFF the power to the Main Unit. Wait at least 30 seconds to release the
pressure and vacuum accumulated in the pneumatic lines.
(3) Open the front cover of the Main Unit, and set the stop bar in place to avoid
accidental closure.
(4) Remove the SRV Tray by pulling it toward you. See Figure 5-5-11.
CAUTION: When removing the SRV tray, do not loosen the thumbscrew fixing the
Manual Aspiration Pipette on the unit.
