5.
the previously used intensity level (fiber
optic light switch must be ‘On’) . When the
dental motor/handpiece is turned off, the
handpiece light will stay on for thirteen
seconds before timing out.
5. Manual – Selects hand/foot control mode
of dental motor. When LED is lit, motor
can be hand activated; when LED is off,
motor can be activated via the foot switch.
6. Reverse – Selects clockwise or counter-
clockwise rotation of the motor handpiece
bur. When the LED light is on, the direction
of the bur is counterclockwise. When the
LED is off, the bur is turning clockwise.
7. Water – Controls the availability of water
to the handpieces. When LED is lit, water
is available to the handpiece.
8. Source – Indicates power source. If 120V
or 230V is powering the system, the LED
will light up. If vehicle 12V/24V is powering
the system, the vehicle LED will light up. If
only battery pack power is applied to the
unit, neither light will be on.
9. Charge – Allows the system to charge the
battery pack from a 120V/230V AC source
or vehicle battery when the LED is on. A
drained battery pack takes less than 4
hours to fully charge. The unit is designed
to charge the battery pack while operating
off 120V/220V AC power or vehicle
12V/24V power.
10. Pump – When LED is on, power is applied
to the pump to allow for air and water
pressure. When LED is off, power is
disengaged from the pump to allow for
water bottle removal without shutting
power off to the chassis or battery charger.
11. Battery Level – Indicates level of charge
for the battery pack that is connected to
the chassis. “FULL” is 32V, with a drop of
1V per LED.
12. Fault – Battery light indicates problem with
connected battery pack. Unit light indicates
problem with the system. (Refer to
Troubleshooting Section, page 13.)
13. Coolant Adj. – Controls the amount of
water flow to the handpiece - turn
clockwise to increase flow.
14. Foot Switch – When either, or both, of the
power switches are in the on position, the
foot switch (s Fig. 6) provides on/off
operation of the dental motor and water
coolant (when water LED is on) to the
handpiece .
15. Three-way Air/Water Syringe (Fig. 6) -
Pressing the left button dispenses water.
Pressing the right button dispenses air.
Pressing both buttons simultaneously
dispenses an air/water mist.
16. Water Supply Bottle (Fig. 6) - The AEU-
14CF Expedition incorporates a self-
contained pressurized water system. This
consists of a 16 ounce clear bottle
dispensing water through the 3-way
Air/Water Syringe and Handpiece Coolant.
The Water Supply Bottle attaches to the
threaded reservoir connector, located
below the pressure gauge.
To refill the Water Supply Bottle:
1. Disengage pump.
2. Unscrew bottle.
3. Fill with water.
4. Screw bottle onto reservoir connector.
5. Re-engage pump
