5 Maintenance and Troubleshooting
9 Upon completion of the cleaning process, the 8000 dispensing arm
and the Apparatus 3 / 7 drive unit return to the home position.
Syringe and Seal Replacement
1 Disconnect all sample tubes from the pump.
2 On the 8000, press MENU > 7 > 6 > 3 to partially extend the syringe
plungers.
3 When the syringe plungers reach approximately 5 mL, turn off the
pump.
4 Disconnect the power cord and communication cables from the
pump.
5 Remove the syringe plunger thumb screw(s).
6 Using a #2 Phillips screwdriver, remove the 4 screws that secure the
retainer block at the top of the syringes.
7 Carefully remove the syringe valve retainer block.
8 Flip the pump so that it is sitting on its top.
9 For improved access to the syringe ferrule, gently slide the syringe
away from the pump while disengaging the plunger and valve from
their locating pins.
10 Unscrew the syringe from the valve using care not to break the glass.
11 If there is a seal within the syringe port on the valve, extract it from
the port.
If the syringe seal eventually develops a leak, retighten the syringe by
hand (18 - 21 oz-in, 1.3 - 1.5 Kg-cm).
If the seal eventually obstructs the media path, new seals are available
for purchase (P/N K1002-00438).
The distance that the valve will move out of the pump is limited by
the valve wires. Use care not to break or damage the valve wires.
