5
Only qualied dentists and dental hygienists should use the AquaCare Twin on
patients.
Before using the AquaCare Twin:
a) Read the manual thoroughly.
b) Make sure the operator of the unit, any assistants, the patient, and anyone
else in the room wear eye protection to BS EN 166 IF 4/5.
c) Make sure the operator of the unit, any assistants, and anyone else in the
room, except the patient, wear respiratory masks to BS EN 149 FF2S.
d) Make sure you are in full control of the handpiece, and are aiming the
handpiece nozzle in a safe direction.
e) Make sure you have selected the correct powder for the treatment you are
performing. Incorrect selection of powder can cause hard tissue damage.
f) Use a high speed intra-oral aspirator during treatment. An extra-oral
aspirator can be used in addition if desired.
g) Ensure machine has adjusted to room temperature (>15°C) before
operating if coming from a cold environment.
ATTENTION- Please read all the following important warnings before
using the AquaCare Twin:
Safety Warnings
AquaCare Twin: Introduction
The disposable feedline and tip should be changed for each patient treatment to
prevent cross-contamination. Ensure that new tips are tted rmly onto the nozzle.
Used feedlines and tips should be discarded. Attempts to reuse the AquaCare feedlines
and tips, or to use them with any other micro abrasion machines could be hazardous.
Patients should consult their physician before having treatment with the
AquaCare Twin if they have:
 a)Respiratorydiculties
b) Asthma
c) Blocked nasal passages
d) A cold
e) A restricted sodium diet
f) Any other medical problem preventing breathing through the nose.
ALWAYS AIM TOWARDS THE INCISAL EDGE OF THE TOOTH.
The AquaCare Twin may cause soft tissue damage, including inammation,
bleeding, and creation of an air embolism. The AquaCare Twin may cause hard
tissue damage, including etching or abrasion of enamel or exposed root surfaces of
the teeth.

Safety Warnings
AquaCare Twin: Introduction
In most cases the plastic tip should last long enough for one treatment. However, during
prolonged treatments the tip may need replacing to prevent erratic ow of uid.Do not use
the handpiece if the hole in the tip of the nozzle has worn to the outer edge, or if the swan
neck tube has been perforated.
Sterilise the handpiece before rst use and between each patient treatment.
Fluidissuppliedtotheunitviatheuidbottle.The AquaCare Twin air inlet should
NEVER be connected to a running water supplyasthiswilloodthemachine.To
rectify this the machine will require a full service and rebuild - this will be carried out
at the customer’s expense.
All powders supplied by Velopex are sterile until opened, and the containers are not reusable.
The powder lines and handpiece should be purged/primed each time you switch between
the powder chambers using the powder selector dial (See MAINTENANCE: PURGING THE
AQUACARE TWIN, Pg 33).
The AquaCare Twin produces ne powder dust when in use. Protect sensitive equipment
from this dust.
Only use parts and consumables supplied by Velopex. Non-Velopex products may damage
the unit or alter the performance. The uid used with the machine must be a biostatic
solution like the AquaSol from Velopex, see page 16.
Site the foot pedal carefully so that it cannot be operated by accident. Always close the foot
pedal safety cover when not in use. Accidental operation can cause an uncontrolled and
dangerous high pressure stream of abrasive powder.
If the foot pedal is released but the powder/uid ow does not stop therefore indicating that
the pedal has jammed in the ON position.
The rst course of action must be to quickly and carefully remove handpiece from the
patients mouth and placing the hand piece to discharge in an extraction unit.The system can
then be disabled by operating the side on/off switch to the off position.
Do not place the unit in direct sunlight.
When turning the AquaCare Twin on and off, ensure that the nozzle is aimed into the inlet of
your evacuation unit, and that the evacuation unit is switched on.
When turning the AquaCare Twin off, wait for the machine to depressurise before attempting
to remove the dosing chamber lids. Depressurising takes roughly 30 seconds.
If the AquaCare Twin is dropped or otherwise damaged, it must not be used until it has been
inspected by a Velopex Representative or Authorised Distributor.
If the AquaCare Twin ceases to operate correctly, or if you experience a
deterioration in performance, see TROUBLESHOOTING, Pg 35-37.

NOTE:
In hot countries, If the air supply is damp it is recommended that a AquaCare DryAir
Box I/MAC8552F is tted in the air input tubing before connecting the supply to the
AquaCare unit.
If the air is damp, the powders in the unit will absorb the dampness and will not ow
correctly.

19AquaCare Twin: Installation
Before adding the powder to complete installation of the AquaCare Twin, you can check that
the installation has been performed correctly using the following procedure:
A. Check that the machine is off.
B. Sterilise the handpiece. Refer to MAINTENANCE: STERILISING THE HANDPIECE, Pg 31.
C. Fit the 0.6mm silver handpiece to the machine.
D. Fit a new disposable feedline and tip.
E. Check that the uid container has been tted.
F. Make sure you are in full control of the handpiece before turning the machine on.
G. Switch the On/Off selector to position On.
H. Press the foot pedal down to the DRY position (1). (See PARTS AND FEATURES: FOOT
PEDAL, Pg 11). Check that air comes out of the nozzle. There should be no uid or
powder.
I. Press the foot pedal down to the WASH position (2). After a few seconds you should
observe the ow of air change to a ne mist.
J. Turn the Fluid volume dial, observing the spray. Place a paper towel under the nozzle at
a distance of 25-30mm to make the effect easier to see. The Fluid volume range varies
between:
DROPLET - Small quantity of water. Very ne mist.
SPRAY - Larger quantity of water. Heavier spray.
K. Set the powder chamber selector to the prep position. Press the foot pedal fully down to
the CUT position (3). You should hear the vibrator start to operate. Turn the media dial to
set the gauge to the midway position. The nozzle will continue to spray a mixture of uid
and water, but no powder as this has not yet been installed. Then change the powder
chamber selector to the prophy position and repeat the process to set the other media
dial.
L. Turn the Power dials, observing the Pressure gauges. The pressure ranges are:
2 - Low energy, gentle cleaning/polishing action.
4 - Medium energy, medium cutting action.
6 - High energy, very fast cutting action.
M. Switch the machine off.
N. Always place back the handpiece in its holder after use.
Installation Test
If your observations do not match the procedure above, check that all INSTALLATION
sections have been completed correctly. If installation problems continue to occur,

AquaCare Twin: Installation
A. Ensure the unit is turned off and is fully depressurised. If the machine has been ON
recently, allow 30 seconds for depressurising before attempting to remove the lid.
B. Unscrew the required dosing chamber lid anti-clockwise 2/3 of a turn to relieve the
pressure. Then unscrew a further turn and lift off.
C. Select the required powder, i.e. Prophy or Prep, and shake the required Powder
Cartridge for 10 to 20 seconds (See TREATMENTS, Pg 26-30).
D. Pull out top yellow insert from the cartridge.
E. Push in the clear lower draw tab on the cartridge.
F. Line up the rib on the outside of the powder cartridge with the slot on the inside of
the required dosing chamber - Prophy (Left) or Prep (Right).
G. Slide the powder cartridge down into the dosing chamber until it sits comfortably
inside. If the cartridge sits unevenly or above the top of the dosing chamber, then lift
it out and re-insert. Check that the rib of the powder cartridge slides down the slot in
the dosing chamber - ret the dosing chamber lid.
H. Close the dosing chamber by turning lid clockwise. Turn rmly until a strong resistance
is felt from the seal engaging with the top of the chamber. Continue to turn the lid
until you feel the lid tighten against a stop. Always make sure the lid is fully closed
before pressurising the machine.
I. To remove a powder cartridge, open the dosing chamber lid and gently lift the
cartridge out of the machine. If the cartridge still contains some powder and will be
used again, carefully pull back to lock the lower tag in position, DO NOT REMOVE IT,
then ret the top insert.
All powder cartridges supplied by Velopex are gamma irradiated. The contents are sterile
until opened. Powder cartridges must not be relled as the cartridges are not reusable.
