a. Remove the piece of sample tubing that contains
the obstruction.
b. Push a clot-removal line, less than 0.020 mm

b. If you disconnected the sample tubing from the
sample connector, disconnect the waste tubing
from the inlet on the reagent manifold and
manually turn the CO-ox pump counterclockwise
to remove the obstruction.
NOTE: If air does not remove the obstruction, place
the waste tubing into a beaker of reagent water, and
manually turn the CO-ox pump counterclockwise to
remove the obstruction.
c. If you disconnected the sample tubing from the
