Figure 5-23 Reservoir Empty Warning
The operator can proceed in different ways, depending on the following conditions:
Note: After three minutes, the pump and centrifuge will stop and the Reservoir Empty alarm
with all its buttons will remain displayed.
• If the reservoir is empty and more blood is expected in the reservoir:
a. Wait until the volume of blood collected in the reservoir is sufficient to complete the bowl
filling.
b. Touch the Fill button to continue with the Fill phase.
• If blood is still present in the reservoir:
a. Check that the connections are properly sealed and eliminate possible occlusions along the fill
line.
Note: To check the current positioning of the tubing going to the bowl, you may need to press
the Stop button then open the centrifuge and clamp lid. In this case, pay close attention to the
correct disposable installation when closing the clamps and centrifuge lid again.
b. Check that the tube going to the bowl is fully down in the air detector seat.
c. Touch the Fill button to continue.
• If the reservoir is empty and no more blood is expected in the reservoir:
a. If the RBC bag contains red blood cells:
• Initiate the Last Bowl function if available (refer to “Last Bowl” on page 7-4).
Note: The “Last Bowl” function is not available when operating in Manual mode.
• Otherwise, touch the “Conc” button to complete the bowl filling by pumping the
contents of the RBC bag into the bowl according to the Concentrate function (refer to
“Adding Fluid to a Partially Filled Bowl: The Concentrate Cycle” on page 6-3).
b. If the RBC bag is empty:
• Either touch the “Return” button to return the contents of the bowl to the reservoir
and then end the case,
• Or continue processing the partially filled bowl by touching the Wash phase
button (or the “Double Wash” button to use double the wash volume) to advance to the
Wash phase. This will result in lower than usual hematocrit and wash quality of the
collected blood.
Note: The “Double Wash” button is not available when operating in Manual mode.
