Water Filling Up Oil Mist Recovery Jar
- Bad gasket on handpiece or coupler is not tight. Remove handpiece coupler, verify gasket and firmly tighten.
- Water condensation from main air compressor is in the air lines. Check central compressor.
Water not Flowing From Handpieces or Air/Water Syringe
- Check the water bottles and ensure they are full, switched on and that the air pressure gauge is reading around 25-
35psi.
- Try switching the bottle selector valve from one bottle to the other as it may be clogged and need replacement (P/N
95-0143).
- Air leak in pick up tube or gasket needs replacement. Verify gasket and change if necessary (P/N 95-0156 see Parts
Catalog for complete list of gasket options and part numbers).
- Bottle threads worn and not sealing correctly. Replace bottles annually or sooner if necessary (P/N 95-0140 or 95-
0140QT).
- Blocked or pinched tubing. Make sure tubing is not pinched. If tubes are not pinched, inspect for blockage.
Water Flows from Air/Water Syringe but not Handpieces
- Needle valve off or pinched water line. Ensure needle flow control valve is opened.
- Check to see if water is not flowing from any handpiece to determine if it is isolated to just one tubing. Ensure that
all the flow control valves for water have been opened. Delivery systems made before 12/06 used an anti-retraction
valve in each handpiece line. If clogged, remove the anti-retraction valve and replace the water relay with ASI’s new
style (P/N 95-0135) that does not over retract.
- Check the water on/off toggle located either on the foot control or on the delivery system to see if it is working.
Remove the cover on the foot pedal from the toggle to see if the signal line could be kinked. Remove the gray air
signal line from the relay and activate the foot pedal and ensure that an air stream is coming out.
- Check the water output side of the relay by disconnecting the tubing from the relay to the control block and pressing
the foot control. If still no flow, replace the water relay valve (see page 10 for water relay options and part numbers).
Water Dripping After Using a Handpiece
- If water drips from only one handpiece, check to see if there is a cracked connector in either end of the handpiece
tubing or the bulkhead itself. Replace the bulkhead or handpiece tubing (see Parts Catalog for tubing options and part
numbers).
- For systems with a foot control toggle switch, check the foot control signal line. If there is a slight kink in the foot control
tubing, it can delay the air from exhausting off the relay and allows water to drip. Replace if necessary (P/N 95-0084
or 95-0242 See section for more information).
- If water drips from several handpieces or if water slowly builds and drips out, the water relay may not be working or
has a small piece of debris in it. Replace the water relay valve (P/N 95-0135).
- Check for air in the water line. Run the handpieces for a minute or two to clear any air bubbles out of the system then
check the air water syringe connection at the bulkhead to be sure it is tight and secure. For models with an air purge
feature, check that this valve is not leaking air into the water side. If this is the problem, replace the valve with a newer,
non-air purge type (P/N 95-0143).
