2. Open the door on the front center of the analyzer to gain access
to the syringe. The syringe is the glass cylinder with a metal
plunger inside, shown in the following graphic.

3. At the base of the syringe, loosen the thumbscrew by turning it
counter-clockwise six quarter-turns.
4. Turn on the analyzer and immediately watch the syringe pump.
5. Within a few seconds, the syringe arm will go down, then start
going up again. As soon as it begins traveling upward, turn off
the analyzer.
CAUTION: Do not turn off the
analyzer as the arm is going
down. The syringe pump valve
will not be in the correct
position, allowing sheath fluid
to drain out of the valve when
you remove the syringe.
6. If the base of the plunger did not come out of the arm when it
cycled, loosen the thumbscrew a little more and very lightly
attempt to lift the plunger away from the base. If the problem
persists, contact Luminex Technical Support.
7. Unscrew the syringe from the top of its housing.
8. Pull the plunger out of the syringe.
9. Remove and replace the plunger seal and the black "O" ring.
10. Replace the plunger into the glass syringe.
