AquaCare: Troubleshooting
Symptom
No air flow through the nozzle.
Action
1. Ensure that the power dial is turned up to at least “2”. This should give a detectable
airflow.
2. Check that the nozzle is not blocked. If blocked remove the handpiece and clear the
blockage with a cleaning wire - 8073F. (See NOTE below)
3. Ensure the twin tube is straight and has no kinks or folds.
4. If the Internal Filters have not been changed over the last 12 months, they can
become soiled, blocking the air line. See ANNUAL SERVICE: REPLACING THE AIR
FILTER, Pg 39.
5. If the Powder Pinch Tube is split it will not operate, preventing air from flowing
to the nozzle. This will need to be resolved by replacing the part. See ANNUAL
SERVICE: REPLACING THE POWDER PINCH TUBE, Pg 39.
Note:
A very common reason for a blocked handpiece is that it hasn’t been returned to
its holder on the machine; (see page 12-item 28) i.e. in a vertical position. If the
handpiece is laid down on a surface, fluid can flow back in to the nozzle and lead to a
blockage when powder is next sent into the handpiece.
Troubleshooting
AquaCare: Troubleshooting
Symptom
No powder flow through the nozzle when the foot pedal is pressed down to the “CUT”
position.
Action
1. Check that you have fitted the Powder Cartridge into the Dosing Chamber. Make
sure that the Powder Cartridge is not empty.
2. Turn the Media Volume control up to maximum.
3. Check that there are no objects blocking the foot pedal from moving normally.
4. Depressurise the machine. Remove the Dosing Chamber Lid and look inside them. In
the centre of each lid you should see a star seal. This should be flat in the lid: if not,
remove and refit, replace if required.
5. Press the foot pedal down to the DRY or WASH position, no. 1 or 2. You should
hear the noise of air flowing through the machine. Now press the foot pedal down
to the CUT position, no. 3. You should hear the noise increase as the vibrator starts
to operate. If you do not hear an increase in noise, then the vibrator may be faulty.
Please contact a Velopex Representative or Authorised Distributor for further help.
Symptom
Irregular flow or no flow of cutting fluid to the tip.
Action
1. Check that the fluid volume control is not set to minimum. Rotate clockwise to
increase fluid volume.
2. Change the feedline and tip. In most cases the plastic tip should last long enough for
an individual patient treatment. However, prolonged treatment or failure to change
feedline and tip between treatments will wear the feedline and tip, causing reduced
or uncontrolled flow. See INSTALLATION: FITTING THE DISPOSABLE FEEDLINE AND
TIP, Pg 17.
3. Ensure the plastic tip is firmly engaged on the cutting nozzle.
4. Check the fluid bottle is filled to at least 50%.
5. The check valve (page 12, Item 32) could be blocked or stuck. Disconnect the fluid
connection and purge the line. This should unblock the valve. If this is not effective,
replace the check valve.
6. Check for a blockage in the supply line. Look at the clear twin tube for any material
blocking the tube.
7. If there are also air bubbles in the fluid tube this can indicate a leaking joint. Look
along the tube to see where the air bubbles are appearing to find the source of the
leak. Check the joint and replace if necessary.
