4. Use the handles on the component mounting panel to pull the panel
forward until it reaches the stop.
NOTE On newer pumps, three red Phillips screws are
installed on the component mounting panel
before shipment from the factory. If the
mounting panel does not move freely, make sure
these screws have been removed.
5. To prevent contamination of pump parts, wear cleanroom gloves
while disassembling the pump head.
6. Disconnect all tubing connections to the pump head with the
defective piston seal.
7. Using a 3.0 mm hex key (P/N 062338), loosen the two screws on the
pump head with the defective seal. Remove the screws, and then
carefully remove the head and place it on a clean surface.
Refer to Figure 9-4
or Figure 9-5 when disassembling and
reassembling the primary pump head or secondary pump head,
respectively.
8. Remove the seal wash body (P/N 062064) from the pump head. Or, if
the seal wash body was not removed with the pump head in Step 7
,
pull it straight out of the pump mechanism now.
9. Pull the piston (P/N 062082) out of the pump mechanism.
NOTE A magnet secures the piston in place. If the
magnetic force makes the piston difficult to
remove, tilt the piston to one side and then pull
it out of the pump mechanism.
Never disassemble the pump head with bare hands. Even minute
particles of dust, dirt, etc., on the check valves or piston can
contaminate the inside of the pump head and result in poor pump
performance.
