WARNING: When re-installing the pump head assembly, the plunger MUST
extend at least 1/2
from the base of the pump (see Figure 9.6). This will
assure proper alignment between the pump head and the drive hub.

Disconnect the tubing and unscrew the cable connectors from the buffer, waste and calibrator bottles on each side of the
instrument.
Lift the bottle tray on the right side of the instrument up and remove it. Remove the bottles from the tray(s) and clean the
bottles and caps with the appropriate disinfecting agent (see 9.1 Cleaning, Disinfecting, and Decontaminating).
Remove the two hex screws holding the pump cover on each side of the instrument. Lift the covers up and remove them.
