Maintenance and Inspections
After priming, perform the inspections in the following sequence before circulation starts:
• Inspection of the motor drive
• Inspection of the ABD/Flow Sensor
• Inspection of the Fast Clamp
Inspection method of the motor drive (Before each use)
1. Clamp the blood outlet line of the centrifugal pump
(Figure 5-6), change the motor speed to 3000 RPM, and
rotate it for approximately 30 seconds.
• There is no liquid leakage, rotation deflection of the centrifugal pump or abnormal
sounds from the Drive Motor.
Figure 5-6
2. Change the motor speed to 0 RPM to stop the centrifugal
pump.
• The centrifugal pump is stopped.
3.
Pull up the slide hook of the Drive Motor (Figure 5-7
a
)
and remove the centrifugal pump from the Drive Motor.
(Figure 5-7
b
)
• There is no abnormality in the centrifugal pump.
Figure 5-7
4. Attach the centrifugal pump into the Drive Motor and
remove the clamp of the blood outlet line.
For instructions on installing the centrifugal pump, refer to “Attaching the
Centrifugal Pump to the Drive Motor” (page 43).
Inspection method of the ABD/Flow Sensor (Before each use)
1. Apply vaseline in the detection window of the ABD/Flow Sensor and attach the clamp-on ABD/
Flow sensor to the tube of the blood circuit.
2. Change the motor speed.
• The flow is displayed in the LCD.
3. Change the motor speed to 0 RPM to stop the centrifugal pump.

• Do not rotate the centrifugal pump for a long period of time (multiple hours)
while clamping the blood outlet line of the centrifugal pump. The priming
solution may be denatured due to heating. The blood may be damaged due
to heating.
