| Problem |
Valves don't close |
| Solution |
- Clean valve using a syringe with warm distilled or sterile water, while simultaneously working the foot pedal. Inject a drop of lubricant into the plunger channel while working the foot pedal.
- Power off. Valve #3 can be manually moved by fitting your left index finger under the cover at a 45° angle, feeling a circular flat disc and physically working the valve. This is the most common valve to get stuck, since it is on the bottom and gets hit with the most BSS.
- Make sure, that lines are properly placed in the valves.

| Problem |
Clog in Aspiration Path |
| Solution |
- Check Pressure Transducer. Unplug the aspiration line and read Actual Vacuum should be close to zero.
- Check reverse flow. Step on foot pedal to activate reflux switch.
- Test: Set flow rate to 12cc/min. Actual Vacuum should be below 100 mmHg.
If not, there is a clog, disconnect instrument from asp line, repeat test.
If OK, instrument is clogged. If not, aspiration line is clogged.
- Clean instrument or line to clear clogs, or change them.

|
| Problem |
Vacuum is not sufficient |
| Solution |
- Is aspiration line placed properly in bottom valve?
- Does aspiration valve close completely? Try to pinch with fingers in step #7.
- Air bubbles in aspiration line? Is priming line dipped in container with water?
- Is pump running freely? Inspect pump tubing. Pull exiting end of
pump tubing. Change to new one, if worn.
- Check O-rings in aspiration plug.
- Does pressure transducer show zero when open?
- Test: Pinch aspiration line and set the flow rate to 20cc/min. Vacuum should easily reach preset 500 mmHg limit.
