3 GENERAL SERVICE INFORMATION This service and parts manual offers information and parts lists not available in the AEU-CF Operation and Maintenance Instruction Manual. It will help you better understand the operation of the AEU-CF Expedition Emergency Field Dental Unit, thereby reducing service time. A Schematic Diagram Set includes part drawings and schematic diagrams which show components in their actual places in the unit relative to one another. A plumbing schematic is provided with water lines indicated in blue. Plumbing parts are called out by Aseptico part number in the assembly drawings. Electrical schematics are provided for the chassis and battery pack with wires color coded. Electrical parts are called out by Aseptico part number in the assembly drawings. Parts are listed and referenced to Figures with callouts in the Parts List. Use the information in the Parts List when ordering replacement parts. Inspection & Operation Verification To verify that the AEU-CF unit is functioning properly, first follow the set-up procedure in the Operation & Maintenance manual. The system is designed to run off of multiple power systems, so it is best to isolate systems during diagnostics. First, plug the system into a 0V/0V power source. The system is auto switching but the fuses should be changed for the appropriate voltage, which is listed on the silkscreen above the receptacle. Turn the power On/Off switch On and the panel should light up and the compressor pump should fill the air and water reservoirs. If the water reservoir is empty, the pump will take longer to charge the system. With the compressor pump engaged, the system should pressurize to approximately PSI, as indicated on the pressure gauge. When the compressor pump is first initialized, a three-way valve allows for the pump not to start against a pressure head. If the unit fails to show any pressure on the gauge, the three-way valve is usually at fault. Inspect the unit for air and water leaks. If the pump fails to shut off and the pressure gauge shows some pressure, then there is a leak present. The electronics have been coated to prevent shock. It is possible to detect air leaks with a tube or a stethoscope, but because of the low pressure, they are hard to detect in this manner. It is better to use the plumbing schematic and isolate the problem by pinching off the lines with clamps, such as a pair of hemostats. If an air leak is not detected on the lines or fittings, check the bottles for tightness and the condition of the seals. To check the three-way syringe, depress the air and water buttons individually and then both buttons together for spray. The spray will be less than a normal dental system, due to the lower pressure of the system. Inspect the water filter on the water pick-up tube. The water filter requires replacement if it becomes clogged and restricts water flow. The compressor pump has a 0 PPI filter on the underside of the chassis that requires replacement if it becomes clogged and restricts air flow. To check the functions of the dental motor and unit, attach motor and foot pedal as described in the Operations Manual. Push the buttons marked Fiber Optic Light and Water so that the LEDs are on. Depress the foot pedal and ensure that handpiece light comes on (you might have to depress the positive[+] button until light is present) and that water comes out of the handpiece. Adjust the water flow with the coolant adjustment knob on the unit. If light fails to come on, first check the bulb in the motor. If bulb is okay, then work your way back through the connectors. If water fails to come out of the handpiece, check the two-way valve. If the motor fails to operate, check the connector pins on the motor and the foot pedal. If the motor fails to operate from the foot pedal, then activate the button marked Manual. If the motor comes on, the problem is in the foot pedal. Check reverse mode by pressing the Reverse button, and check the motor speed by pressing the positive[+] and negative[-] buttons. Remove the AC power cable and attach the vehicle battery cable to the chassis and either a V or V battery system. Follow the setup procedure in the Operation Manual. Turn the battery on/off switch on and the unit should light up. If the unit fails to light up, remove the chassis as described later in this manual (refer to page ) and check the amp fuse coming from the vehicle receptacle on the inside of the unit. To check the operation from the battery packs, remove other sources of power. Attach the battery pack cable from a battery pack to the unit. Turn the battery on/off switch on and the unit should light up and show the charge level of the battery pack. If the unit fails to come on, check the connections from the battery pack to the unit. To check the operation of the charging system, leave the battery pack hooked up to the unit and apply either 0V/0V or V/V vehicle power to the unit. The unit will take power from the higher source. If 0V/0V power is applied, the power on/off switch must be turned on to check the charging. If power is coming from V/V battery, then only the battery switch needs to be on. Press the Charge button on the unit and ensure that the LED lights up. The above procedures describe basic inspection and verification of the AEU-CF system. If the unit still does not perform as required, further diagnosis of components in the system may require service. Use the Trouble Shooting section as a guide to symptoms and appropriate procedures to fix various problems. Page

4 Cleaning and Lubrication When servicing the AEU-CF Emergency Field Dental Unit, the parts of any component disassembled should be thoroughly cleaned and inspected before reassembly. A hot detergent solution is an effective cleaner on all non-electrical parts. Flush all non-electrical parts with clear, hot water. 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. Use a silicone base lubricating grease, such as Dow Corning No. 0 to lubricate O-rings and seals in the system. Before performing any reassembly of parts that contain O-rings or seals, apply a light coat of silicone grease. This will make installation easier and prevent the O-rings or seals from being damaged. WATER LINES - Prepare a :0 bleach solution ( part household bleach to parts water). Remove water reservoir and discard residual water. Replace empty water reservoir and air purge all waterlines. Fill water reservoir with bleach solution. Run bleach through all lines. Allow bleach solution to stand in lines for 0 minutes. Remove water reservoir and discard bleach. Flush all lines thoroughly with clean water. Air purge and leave lines dry until next clinical use. SPECIFICATIONS Size: x. x.
