4. Use the 3-Way Air/Water Syringe as necessary for irrigation
or drying.
5. Adjust the vacuum pressure by moving the valves on both
the HVE and saliva ejector vacuum heads.
6. Empty the Vacuum Waste Tank when it is 3/4 full.
STERILIZATION AND MAINTENANCE:
Because of its simple design, the Aseptico ADU-
17A Express Air requires very little maintenance. Any
maintenance that is needed can be performed in minutes.
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 into the cap.
Operate the air/water syringe and handpiece with water
coolant ‘ON’ until just air comes through the water line.
Pack unit and store as normal.
HANDPIECE FLUSH
Flush the handpiece for about 5 seconds after every
patient, and about 20 seconds at the beginning of each
day.
GENERAL CLEANING
The external surfaces of the case should be cleaned using
a soft cloth moistened with a mild detergent solution. Any
external surfaces of the unit that are contacted during use
should be wiped down with a soft cloth moistened with
a disinfectant at the beginning of each day and between
each patient use.
WATER LINES
Disinfect the water lines weekly. Prepare a 1:10 bleach
solution (1 part household bleach to 9 parts water).
Remove water reservoir and discard residual water.
Replace empty water supply tank and air purge all
waterlines. Fill water supply tank with bleach solution. Run
bleach solution through all lines. Allow bleach solution to
stand in lines for 10 minutes. Remove water supply tank
and discard bleach.
Flush water supply tank and all
lines thoroughly with clean water.
Air purge and leave
lines dry until next clinical use.
VACUUM SYSTEM
The HVE and Saliva Ejector Valves are fully autoclavable.
Remove the valves from the hoses before autoclaving. The
vacuum hoses should not be autoclaved. Clean hoses with
a disinfectant solution. CAUTION: Use only NON-foaming
cleansers in the vaccum lines.
SYRINGE TIPS
The ADU-17A unit features a three-way air/water syringe
with 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. 7). 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.
This device requires periodic maintenance to remove
dust in and around the compressor every 12 months or if
accumulations are seen. The fan on the unit vents air from
inside the device to the outside. With the unit operating,
use compressed air to spray into the intake vents and blow
dust out of the unit.
