• Press the POWER button on the front of the DP/SP for 2 seconds
to turn off the pump.
3. Open the DP/SP door to access the mechanical components.
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
damaged piston.
7. Using a 3.0 mm hex key (P/N 062338), loosen the Allen screws on
the pump head with the damaged piston. Remove the Allen screws,
and then carefully remove the head and place it on a clean surface.
8. If the piston was not removed with the pump head in Step 7
, remove
the piston now by pulling it straight 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.
9. If the piston is broken, be sure to remove all broken pieces. If
necessary, flush the pump head with ASTM Type I (18 megohm-cm)
filtered and deionized water to remove all debris.
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.
