automatically shut off. When a handpiece
is removed from it's holder, pressure is
automatically opened and ready for use
with foot control.
The amount of air pressure supplied to
each handpiece may be adjusted by
turning the flow control for that handpiece
on the control block (See page 8).
3. WET/DRY FOOT CONTROL (Fig. 8) - The
foot control activates the handpieces and
water coolant spray.
Position the foot control on the floor. For
handpiece operation, apply foot pressure
to any part of the center disk. The
handpiece must be removed from its
holder before operation can begin.
OPERATION FUNCTIONS:
1. THREE-WAY AIR/WATER SYRINGE -
Depress the right button for air operation,
and the left button for water operation.
Depressing both buttons will create a mist.
The syringe features quick-change
autoclavable tips: To remove a tip, press
on the locking collar surrounding the tip
socket and pull the used tip straight out of
the socket (see Fig. 6). To insert a new tip,
press locking collar and push tip into
socket as far as it will go. Release collar
and gently tug on tip before using to
ensure that tip is securely locked into
socket.
Syringe Tip Sterilization:
1) Remove contaminated syringe tip.
2) Remove all visible signs of contamination
before autoclaving.
3) Autoclave tip at 132° C (270° F) for ten
minutes.
4) Sterilize between each patient use.
NOTE: Since only the tips can be
autoclaved, it is recommended that the
air/water syringe be bagged with a
disposable, single-use plastic sleeve
between each patient use.
2. HAND IECE CONTROLS (Fig. 7) - The
Aseptico ADU-25 includes two handpieces
mounted to the front bar. These are fully
automatic. By placing a handpiece into its

To activate the water coolant, move the
wet/dry toggle switch on the foot pedal to
the right position. Move the toggle switch
to the left position to disable water coolant.
4. WATER SU LY TANK (Optional) - The
Aseptico ADU-25 may incorporate a self
contained pressurized water system (Fig.
9). This consists of a 1-liter HDPE tank
dispensing water through the 3-way syringe
and handpiece control. The water tank is
pressurized to a constant 35 pounds per
square-inch gauge (PSIG) during use.
Before removing the tank for refilling, it
must be depressurized by turning the tank
1/4 turn counterclockwise. The tank is
removed by unscrewing it from its mount
at the bottom right rear of the chassis.
After the tank is filled, screw it back onto
the mount. Cleaning and sanitization of
the tank is recommended between uses.
5. RESSURE GAUGE (Fig. 10) - The
pressure gauge on the right panel gives
you a visual indication of the handpiece
drive pressure.
6. WATER COOLANT FLOW CONTROL
(Fig. 10) - Adjusts the flow of water coolant
to the handpiece control.
7. FLUSH TOGGLE (Fig. 10) - The flush
toggle located on the right side of the
chassis allows you to quickly and
completely flush your handpieces, washing
away contaminants which may have
accumulated in the handpiece and tubing.
You should flush the handpieces for about
5 seconds after every patient, and about
20 seconds at the beginning of each day
to reduce overnight bacterial accumulation
which may have occurred.
To flush your handpieces, remove them
from their holder, directing the spray away
from you and into a basin, then flip the
flush toggle and hold the desired number
of seconds. Release the flush toggle.
8. AA-21 HIGH VOLUME VACUUM
SYSTEM (Optional) - The AA-21 Steri-Vac
is an air powered, self contained oral
evacuator system. It is supplied with a
plastic waste container and a single high
velocity hose. (Fig. 11)
Remove the vacuum bottle and hose
assembly from packing and install into the
quick disconnect at the back of the
delivery head.
To operate, remove the vacuum hose from
holder and insert a standard oral evacuator
tip. Depress the on/off switch on the side
of the hose end for vacuum.

Waste from the vacuum system will collect
in the attached plastic bottle. When the
waste container is 3/4 full it should be
emptied. After each use, the vacuum
system should be cleaned by running
clean water or a vacuum system cleanser
through the evacuator hose and
thoroughly cleaning waste bottle.
CAUTION: Use only NON-foaming
cleansers in the vaccum lines. A small and
large capacity waste container are
available and are interchangeable. The
ADU-25 is supplied with a large capacity
container.
9. AA-25 SALIVA EJECTOR SYSTEM-
(Optional) - The AA-25 Saliva Ejector is
an air powered, self contained oral
evacuation system. It is supplied with a
plastic waste container and a single low
velocity hose (Fig.12).

To operate, remove the saliva ejector valve
from the holder and insert a standard
saliva ejector tip. Turn the vacuum toggle
switch, located on the right side of the cart,
to the 'ON' position. The vacuum may be
adjusted by moving the lever valve on the
saliva ejector tip. The lever valve assembly
snaps apart at the swivel and may be
autoclaved.
Waste from the vacuum system will collect
in the attached plastic bottle. When the
waste container is 3/4 full, it must be
emptied to prevent a back-up in the
system. After each use, the vacuum
system should be cleaned by running
clean water or vacuum system cleanser
through the evacuator hose and thoroughly
cleaning the waste bottle. CAUTION: Use
only NON-foaming cleansers in the
vaccum lines.
10. AA-290CK CENTRAL VACUUM KIT
(Optional) - The AA-290C it (Fig.13) is
used with a central vacuum system. It
includes a central vacuum canister with
disposable solids collector, an autoclavable
central vacuum lever valve (with 5 feet of
tubing), and an autoclavable saliva ejector
tip valve (with 5 feet of tubing). An
industry-standard 1/2-inch connection hose
provides easy adaptation to the central
vacuum system.

ROUTINE ADJUSTMENTS:
1. WATER COOLANT FLOW ADJUSTMENT
The water coolant to the handpiece control
can be varied from a fine fog spray to a
heavy stream.
Install and run a handpiece at a midrange
speed. Make sure the wet/dry toggle is in
the 'ON' position on the foot control. Turn
the water coolant flow control located
along the right side of the chassis
clockwise until it seats softly. Begin turning
counterclockwise until a fine mist is visible.
This will provide excellent cooling while
burr is cutting.
2. SYRINGE AIR/WATER FLOW
ADJUSTMENT (Fig. 14) - The syringe flow
adjustment block is located inside the
delivery head near the left rear corner and
has two slotted adjustment screws on top.
To open the chassis, remove the Ritter
tray and pad from atop the unit and lift the
lid. The outside screw adjusts air flow and
the inside screw adjusts water flow.
Turning the adjustment screws clockwise
will decrease the pressure and
counterclockwise will increase pressure.
3. HAND IECE RESSURE ADJUSTMENT
(Fig. 15) - The amount of air pressure
supplied to each handpiece may be
adjusted by turning the flow control for that
handpiece on the control block. The
control block is located at the front right of
the unit under the lid.
4. AIR SU LY RESSURE REGULATOR
The regulator valve located on the
underside of the chassis near the pressure
gauge at the right rear corner of the chassis
controls the line pressure from the
compressed air source to the unit. Turning
the valve stem clockwise will increase this
pressure and counterclockwise will
decrease pressure (Fig. 16).
5. WATER RESSURE VALVE - The water
tank is pressurized to a constant 35 PSIG
by a fixed regulator inside the chassis.
Adjustment is unnecessary.

MAINTENANCE:
Because of its simple design, the Aseptico
ADU-25 Custom Cart requires very little
maintenance. Any maintenance that is
needed can be performed in minutes.
1. BLEEDING THE SYSTEM - If the unit will
not be used for an extended period of
time, or the unit might be subjected to
freezing conditions, you should bleed the
system.
Simply empty the contents of the water
supply tank and install the tank back onto
the quick disconnect. Operate the air/water
syringe and highspeed handpiece with
water coolant 'ON' until just air comes
through the water lines. Pack unit and
store as normal.
2. HAND IECE FLUSH - Flush the
handpieces for about 5 seconds after
every patient, and about 20 seconds at the
beginning of each day. Refer to page 4.
3. GENERAL CLEANING - The cart exterior
is designed to make cleaning and the use
of prophylactic barriers as easy as
possible. The external surfaces of the cart
should be cleaned using a mild solution of
liquid detergent and water. Any external
surfaces of the unit that are contacted
during use should carefully be wiped down
with a disinfectant at the beginning of each
day and between each patient.
As described in the vacuum section the
high and low volume vacuum systems
should always be thoroughly cleaned after
use.
4. ACKING THE UNIT FOR
TRANS ORTATION - If the ADU-25 unit is
going to be transported, it is recommended
that the original or similar packing material
be put into place to avoid dents and
scratches from parts inside of the box
shifting.
