After Each Use. . . Clean and Check your Components
Check roller pumps. See that in Stop mode the roller assembly does not move and
the flow or speed display is blank.
See that in Forward mode, the roller assembly turns in the
direction of forward flow and the display speed increases
accordingly up to approximately 250 RPM.
See that the pump pauses when the Pump Safety Cover is
opened and restarts when the cover is closed.
Check that the tube guide rollers are free of chips, cracks, or
breaks.
See that the tube guide rollers and the occlusion rollers
rotate freely.
Check that the occlusion knob turns freely and with no significant
change in resistance. If the occlusion knob does not turn freely or
the resistance changes, contact your Terumo Customer Service.
Check the centrifugal pump. See that in Stop mode the drive motor is stopped and the
speed is at 0 RPM.
See that in Start mode the motor starts and the speed
display increases accordingly up to 3600 RPM.
Place the protective cover over the drive motor receptacle

Check the Gas Flow. Connect the air or 95/5 and oxygen to the proper gas supplies.
Turn the FiO
2
to 100% using either the control knob or CCM
control. Set the gas flow rate to maximum by turning knob fully
counterclockwise multiple times. The gas flow display on the
CCM should read >10, indicating that the gas flow rate is greater
than 10 L/min, and there is an unrestricted flow from the oxygen
inlet through the system. The FiO
2
and %O
2
display on the CCM
should read 1.00 and 100%, respectively. The %O
2
reading
should be within 90% of the FiO
2
setpoint within 20 seconds.
Turn the FiO
2
to 21% if using air or 95% if using 95/5 using either
the control knob or CCM control. The gas flow display on the
CCM should read >10, indicating that the gas flow rate is greater
than 10 L/min, and there is an unrestricted flow from the air inlet
through the system. If using air, the FiO
2
and %O
2
display on the
CCM should read 0.21 and 21%, respectively. If using 95/5, the
FiO
2
and %O
2
will display 0.95 and 95%, respectively. The %O
2
reading should be within 90% of the FiO
2
setpoint within 20
seconds.
