Troubleshooting
AquaCare Twin: Troubleshooting
If you are having problems with your AquaCare Twin, please follow the steps
below before proceeding further as these will often resolve a problem.
1. Ensure that the compressed air supply is at the specified pressure, connected and
on.
2. Ensure that the unit is switched on.
3. Check that none of the controls are set to minimum.
4. Check that the colour coded foot pedal hoses have been correctly connected to
their matching terminals on the back of the machine.
5. Check the fluid bottle is at least 50% full.
6. Ensure the dosing chambers are correctly loaded with the required powder pot,
and that the powder pot contains an ample level of powder.
7. Check the Dosing Chamber Lid is screwed on securely and correctly.
8. Check that there is no water or wet air contaminating the pneumatic system. This
can occur if the compressed air source is not filtered effectively enough. If this is
the case, contact a Velopex Representative or Authorised Dealer who will be able
to assess the damage to the AquaCare unit.
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.
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 38.
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 38.
Note:
A very common reason for a blocked handpiece is that it hasn’t been returned to its
holder on the machine; 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.
