Power Loss
If power is lost while the Angel System is processing, and residual blood/bone
marrow is in the Variable Volume Separation Chamber, follow these steps to safely
remove the Angel Processing Set from the machine:
1. Do not remove the Pump Loop Tubing from the Pump Rotor until the handle on the
Valve Assembly is pointed toward the Whole Blood Compartment port.
If required, manually turn the handle on the Valve Assembly to the Whole Blood
Compartment port (see Figure 3-21).
1. Whole Blood Compartment Port
Figure 3-21 Correct Valve Assembly Handle Position
2. Remove the Pump Loop Tubing from the Pump Rotor to release fluid pressure on
the Variable Volume Separation Chamber, to allow the residual blood/bone marrow
to flow to the Whole Blood Compartment of the three- compartment reservoir bag.
3. After the blood or the mixture of blood and bone marrow has emptied from the
Variable Volume Separation Chamber into the Whole Blood Compartment, remove
the Angel Processing Set from the machine (see step 5 on page 3-4).
