Installing Tubing Maintenance Kit
Changing the Instrument Tubing
It is recommended that the pump head tubing be replaced twice a year at a minimum, or as
needed.
The six month maintenance kit (2230XPMK) contains completely assembled tubing sets.
To change the tubing proceed as follows: Press the STOP key.
To minimize contact with the reagents, it is highly recommended that you empty out the
contents of the tubing using the PRIME back method as described below:
Press MENU and scroll down to SERVICES and then select PRIME FLUIDICS and then set the
PRIMING VOLUME to - 5 mL. This step allows the user to pump back the reagents contents of
the connecting tubing, including the peristaltic pump tubing.
Scroll up to each of the reagents and press ENTER to pump back the selected reagent fluid into
its container. Repeat for each reagent (1, 2 & 3).
Disconnect the tubing. Replace one a time to reduce the risk of errors in connection.
Remove tubing in front of the valves by gently pulling it out of the groove. Press in on the center
button and then pull the tube out of the groove to remove the rear tube. Refer to Section 3 for
more details.
Replace the pump tubing as described in
Plumbing Connections Section
.
Replace with identical tubing from the maintenance kit by reversing the procedure. Apply
silicone lubricant (supplied with the kit) to the pump rollers before re-installing the tubing.
