9.6.2 Installing the New Piston
Slide the new piston (P/N 062082) partway into the pump head;
approximately 6 mm (1/4 in) of the sapphire part of the piston should
extend from the head.
9.6.3 Reinstalling the Pump Head
1. Place the pump head back on the pump.
2. Reinstall the screws in the pump head. Using the 3.0 mm hex key

with the pump head. Then, tighten the screws another one-quarter to
one-half turn, one-eighth of a turn at a time.
3. Reconnect all tubing connections to the pump head. Tighten
connections fingertight, and then tighten an additional one-quarter
turn only.
4. Push the component mounting panel back into the enclosure, using
the handle in the center of the panel. Close the DP/SP door.
5. Press the
POWER button on the front of the DP/SP to turn on the
pump.
6. Select the Connected check box on the Control panel to reconnect
the pump to the software.
