GENERAL SERVICE INFORMATION
This service and parts manual offers technicians informa-
tion and parts lists not available in the A U-7000L-70V or
A U-7000 -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 7000L/ units are set up and functioning
properly, refer to the set up 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 7000
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 ‘ ’ Type 20:1 handpiece to the motor, and
install the Dynamometer Adapter into the handpiece (see
Fig. 3).
Attach the supplied A -70V2 variable-speed foot control
to the connector located on the rear of the unit (see Fig.
1). The A -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 System Troubleshooting on page 20. 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 7000L/ 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 7000L/7000 handpiece/motor.
Follow the menu prompts displayed on the screen to run the
handpiece through the two-part calibration procedure (r f r
to “OPERATION” s ction in th Op ration Manual for
compl t calibration instructions).
Press and hold the “S TUP” button for one second to enter
the A U-7000L/7000 System Setup program (see Fig. 5).
Follow the menu prompts on the screen to recall the factory
setup, enable warning tones, and select other system
options (r f r to “OPERATION/Syst m S tup” s ction in th
Op ration Manual for compl t s tup instructions).
Verify that the “SP D”, “TORQU ”, “FLOW”, “PR S TS”,
and key pad navigation buttons are functioning properly
(see Fig. 5). Press each button to verify that its displayed
values and/or L Ds change accordingly (r f r to
“CONTROL PANEL FUNCTIONS” s ction in th Op ration
Manual for compl t d scriptions of all k y pad buttons). On
the A U-7000L unit only, press the Illumination Button (see
Fig. 5) and confirm that the L D on the handpiece

Depress each of the buttons on the A -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) (r f r to “VARIABLE-SPEED FOOT
CONTROL OPERATION” s ction in th Op ration Manual
for compl t instructions on s tting up and op rating th
foot control).
The above procedures describe basic inspection and
verification of the A U-7000L/7000 . 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 an Lubrication
When servicing the A U-7000L/7000 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.
lectrical parts should be cleaned with an appropriate
electrical parts cleaner or air.
Refer to “ST RILIZATION & MAINT NANC ” Sections,
pages 21 & 22, in this manual for additional cleaning
instructions.
ESD PRECAUTIONS
The following electrostatic controls must be used when
working on this unit:
ESD Training and Standards:
mployees handling electronic sub-assemblies and SD
sensitive components are expected to be trained.
Training should be based on IPC-A-610 or equivalent
SD standard ANSI/ SD-S-20-20 – Protection of
lectrical and lectronic Parts, Assemblies and
quipment.
ESD Static Controlled Area:
Areas that are designated for handling and working on
electronic sub-assemblies or their components should be
marked off with signs indicating the area where SD
controls are to be enforced. These areas are to be kept
clear from persons that are not trained to prevent SD
damage from occurring.
ESD Environment:
The work area is to be free of all static generating
materials, such as plastic containers, water bottles, plastic
bags, plastic objects, such as plastic pens, heat guns
(unless made for the SD environment).
ESD Jackets:
Clothing should be non-static generating (cotton).
Static generating clothing (e.g. wool, acrylic, nylon) must
be covered with an SD jacket that is buttoned closed.
Optional gloves:
Nitrile gloves may be used to cover the hands when
working, but are not required.
Seating:
SD Chairs should be used in place of static generating
chairs (e.g. modern office seating use static generating
materials).
Storage and packaging:
All circuit boards and components are to be stored on or
in static dissipative or static shielding material, throughout
shipping and storage.
ESD Wrist Strap and Mat Routine Checks:
The wrist strap should be checked daily using an SD
wrist strap testing station. See chart below.

WARNING
ELECTRICAL SAFETY TESTS
Whenever repairs on any A U-7000L/7000 unit
involves safety issues, such as electrical malfunctions or
changeout of critical components in the electrical circuit,
i.e., main power board or transformer, it is recommended
that the Hi-Pot and/or Ground Bond Safety Tests below
be performed after repairs are completed. If the tech-
nician determines that Safety Tests are required, the tests
should consist of three separate tests, typically performed
in tandem via a single Hi-Pot test/measurement device:
1. Perform lectrical Safety Tests:
1.1. Attach an A -230L-40 motor (7000L) or an A -
230M-40 motor (7000 ) to the unit console.
1.2. Conduct a Ground Bond Test between arth
Ground at the power inlet and the chassis at the
pump drain opening (see Fig. 30). Test
parameters are 25 Amps for two seconds with
an allowed resistance of no more than 0.1
Ohms.
1.3. Conduct a Dielectric Withstand Test between
Mains at the power inlet and the pump drain
opening (see Fig. 30). Perform test with the
power inlet switch in the “ON” position. Test
parameters are 2520 VDC for one second with
an allowed leakage current of 1.0mA.
1.4. Conduct a Dielectric Withstand Test between
Mains at the power inlet and the motor housing
(see Fig. 31). Test is to be performed with the
power inlet switch in the “ON” position and the
return lead of the test equipment connected to
the -coupling of the motor body. Test
parameters are 4250 VDC for one second with
an allowed leakage current of 1.0mA.
2. Using a multimeter (Amprobe 38XR-A or equivalent
meter with 0.01nF resolution), measure the
capacitance between the sheet metal chassis of the
console and the DC return pin (Pin #4) of the
footswitch connector (see Fig. 32). Result is
acceptable if the capacitance measured is 5.3-8.0
nF.
IMPORTANT: Any system that fails any of the
above tests must be removed from service and
thoroughly examined, repaired and retested by a
qualified technician.
NOTE: Although Aseptico uses the Associated
Research, Inc. Model 7564SA Hipot/Ground Tester
for these tests, alternative equipment with
equivalent setup and testing specifications may be
used. nsure that the above test parameters are
set up correctly before conducting the tests.
