Bottle Tubing - Xylem YSI 2500 User Manual

Reassemble the pump, position the plunger as shown in Figure 8-5 and install it back on the instrument.
WARNING: When re-installing the pump head assembly, the plunger MUST
extend at least 1/2" from the base of the pump (see Figure 8-5). 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

Lift the bottle tray on the right side of the instrument up and remove it. Remove the bottles from the tray and clean the
bottles and caps with the appropriate disinfecting agent (see 8.1 Cleaning, Disinfecting, and Decontaminating).
Remove the two hex screws holding the pump cover on the right side of the instrument. Lift the cover up and remove it.
