GENERAL SERVICE INFORMATION
This service and parts manual offers technicians informa-
tion and parts lists not available in the AEU-6000 or AEU-
6000-70V Operation and Maintenance Instruction
Manuals. This manual will help you better understand
how the dental units work, thereby reducing service time.
Parts are listed and referenced to callouts in the Parts
Lists, pages 24-26. Use the information in the Parts List
when ordering replacement parts.
Inspection & Operation Verification
To verify that the 6000 units are set up and functioning
properly, refer to the setup instructions below and in their
respective Operation & Maintenance manuals. First, attach
the power cord to the back of the console and plug into a
grounded electrical outlet (see Fig. 1). NOTE: Both 6000
series units are compatible with 115VAC, 60Hz and
230VAC, 50Hz voltages and frequencies.
Connect the motor/cable to the receptacle on the lower
right front of the console
(see Fig. 2). When
attaching the cable to unit,
align the red dot on cable
connector with the arrows
located at top center of
receptacle and bezel, and
gently push the connector
straight in to lock into place.
Remove cord by pushing inward slightly on the strain relief,
then grasping connector body near the red dot and pulling the
connector straight out of receptacle.
Attach an ‘E’ Type 20:1 handpiece to the motor, and
install a bur or drill into the handpiece (see Fig. 3).
Attach the supplied AE-70V2 variable-speed foot control
to the connector located on the rear of the unit (see Fig.
1). The AE-23 Irrigation Tubing Set does not need to be
installed during routine maintenance and troubleshooting
of the console and/or motor. For troubleshooting irrigation
problems relative to the pump and/or irrigation tubing,
refer to General Troubleshooting on page 10. Turn the
power switch on the rear panel of the console to the ‘On’
(-) position. The vacuum fluorescent display should show
the startup screen for a few seconds, then default to the
operating parameters of the last-used preset (or preset #1
if the factory setup was recalled). The startup screen will
display the Aseptico logo and then the software version
onboard your 6000/E unit (see Fig. 4).
Press the “RATIO” Up or Down buttons to select “20:1” on
the display (see Fig. 5). Depress the foot control pedal to
verify that the motor and pump operates. Press the “CAL”
button to calibrate the 6000/-70V handpiece/motor - follow
the menu prompts displayed on the screen (refer to
“OPERATION” section in the Operation Manual for
complete calibration instructions).
Press and hold the “CAL” button for one second to restore
the System’s factory defaults settings (see Fig. 5). Follow
the menu prompts on the screen to recall the factory setup
(refer to “OPERATION/System Setup” section in the
Operation Manual for complete factory recall instructions).
Verify that the “RATIO”, “SPEED”, “TORQUE”, “FLOW”, and
“PRESETS” buttons are functioning properly (see Fig. 5).
Press each button to verify that its displayed values and/or
LEDs change accordingly (refer to “CONTROL PANEL
FUNCTIONS” section in the Operation Manual for complete
descriptions of all key pad buttons).

Depress each of the buttons on the AE-70V2 foot control to
verify that they control motor direction, turn the pump
On/Off, and step through the torque settings and presets
correctly (see Fig. 6) (refer to “VARIABLE-SPEED FOOT
CONTROL OPERATION” section in the Operation Manual
for complete instructions on setting up and operating the
foot control).
The above procedures describe basic inspection and
verification of the AEU-6000/-70V. If the unit performs
normally during calibration and setup, and all the key pad
buttons function properly, no further testing of the console
is needed. If the unit does not perform as required, further
diagnosis and service of system components is required.
Use the Troubleshooting sections in this manual as a
guide to diagnose problems and perform repairs.
Cleaning and Lubrication
When servicing the AEU-6000/-70V unit, the parts of any
component disassembled should be thoroughly cleaned
and inspected before reassembly. A mild detergent
solution is an effective cleaner on all non-electrical parts.
Abrasive cleaners have the potential to damage surface
finishes and should be avoided. Any wiping should be
done with a soft lint-free cloth.
Electrical parts should be cleaned with an appropriate
electrical parts cleaner or air.
Refer to “STERILIZATION & MAINTENANCE” Sections,
pages 20 & 21, in this manual for additional cleaning
instructions.
