8.2 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 (K9705CL) 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 here:
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 & 4).
Disconnect the tubing. Replace to reduce the risk of errors in connection.
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 to the pump rollers before re-installing the tubing.
NOTE
PRIME FLUIDICS menu the (-) sign for the priming volume will be reset to (+) upon next menu
entry.
