Troubleshooting the Analyzer 5-45
To install the flowcell
1. Hold the flowcell by its red threaded fitting and place it gently into the optics
assembly.
2. Place the flowcell onto the guide pins. Make sure that it is resting on both
pins. The flowcell will be at a 4
°
angle. Tighten the captive flowcell release
screw to lock the flowcell into position.
3. Reconnect the hydraulic lines to the CFM. Reconnect the flowcell tube
assembly fitting to the appropriate hydraulic valve, V234. Hand tighten the
connection enough to prevent leaks.
IMPORTANT
To avoid incorrect patient data, make sure that each hydraulic line is attached to
the correct CFM nipple.
To check analyzer performance
1. Bring the analyzer to the Ready to Run mode, then run a saline primer.
2. Check the flowcell connections for leaks and verify saline background on the
Startup tab.
3. At the Procedures menu, select the Align Optics tab.
4. Select the Info button for help.
5. At the Logs menu, select Cal/Gain Logs and check gain factors. Adjust gains
if necessary.
6. Run a whole-blood primer, and then run controls to verify analyzer
performance.
7. If the control results are acceptable to the laboratory, no additional action is
required and normal operation can be resumed.
Replacing the syringes
To remove and replace one of the syringes, follow instructions in the
Maintenance section, replacing the Syringe Plungers.
Replacing the vacuum pump filter (vacushield)
The vacuum filter traps liquid that would otherwise enter and damage the
vacuum pump. Replace this filter if it becomes saturated with liquid.
