8 Syringe Maintenance
Moving parts of the Syringe Module may cause hand injuries. Never run a measurement on the Cedex
HiRes Analyzer without the protective cover for the Syringe Module in place. When performing a syringe
maintenance, be aware of the risks from moving parts.
The flow chamber, tubes, syringe, and 8-way valve are cleaned during the Intensive Clean routine (see “Cleaning
Options”).
However, the syringe is subject to wear and tear and must, therefore, be regularly replaced to maximize the life
span of the 8-way valve and to guarantee optimal performance. The syringe should be replaced approximately
every 6 months under normal use of the Analyzer. More frequent use may require more frequent changing of
the syringe.
To change the syringe, follow the steps specified in the sections below:
8.1 Removing the Syringe
1
Click on Syringe Maintenance in the Functions menu of the Cedex Control Center.
The Syringe Maintenance dialog box will open (see Figure 40).
2
Click on the REMOVE SYRINGE button. The syringe barrel will be moved to a position to allow easy removal.
3
Remove the protective cover with the use of a Phillips head screwdriver. Turn the screws 90 degrees
counter-clockwise to release the screws.
4
Hold the syringe barrel by the Luer lock and turn it counterclockwise to remove it from the 8-way valve
(see Figure 41).
5
Once the connection is loosened, keep holding the syringe barrel in an upright position beneath the 8-way
valve to prevent it from jamming with the plunger.
6
Remove the bottom screw that connects the plunger to the Syringe Module with the other hand.
7
Remove the syringe from the Syringe Module.
