14 Section IV Testing Delivery System Utility Service Center 1. Turn on all services supplying the USC. 2. Open the air and water manual stop valves by turning the knobs counterclockwise. 3. Inspect all joints and connections for leaks. 4. Plug the power cord from the USC into an electrical outlet. 5. Turn the master switch ON. 6. Inspect for leaks in the delivery head. Air and Water Filter/Regulators If the regulators are not set at 80 PSI for air and 40 PSI for water, do the following adjustment process: 1. Pull the locking knob. Master ON/OFF Switch NOTICE The air regulator is factory preset to deliver 80 PSI. The water regulator is preset to deliver 40 PSI. 2. Turn the adjustment knob on each regulator until the correct pressure reading is reached. 3. When finished, push the locking knob down. Foot Control & Handpiece CAUTION Before connecting handpieces, all air must be purged from the coolant water lines to allow the system to function properly. 2. Purge air from the coolant water lines on each handpiece as follows: a. Turn the coolant water adjustment knobs counterclockwise to open the coolant valve. Coolant Water Adjustment Knobs b. Remove the handpiece tubing from holder. c. While facing the deliver head, start with the handpiece tubing on the far left; then fully depress the foot control to allow water to flow into a sink or other container. d. As the water is flowing, continue to purge the remaining tubings (moving from the left tubing to the right tubing). e. Allow water to flow freely from all tubings for approximately two minutes to ensure all air has escaped. 3. Attach the handpieces to the tubing as follows: a. Slide the connector nut down along the tubing to expose the handpiece adaptor. b. Carefully align and insert the handpiece base into the adaptor. c. Replace and tighten the connector nut to complete installation. Handpiece Coolant Water Lines 1. At the foot control, flip the toggle valve to WET. Wet WET/DRY Toggle Valve Tubing Adaptor Nut (Insert Air Pressure Gauge Here) axcs Basic-Duo CMU 13

15 Section IV Testing Air Pressure 1. Flip the toggle valve from WET to DRY at the foot control. 2. To adjust the individual handpiece drive air pressure to the manufacturer's specifications do the following procedure: a. Remove the handpiece from its holder. b. Insert an air pressure gauge as indicated in the illustration above. c. Hold the handpiece, fully depress the foot control and observe the amount of air pressure delivered to the handpiece. d. Locate the air pressure adjustment screws on the bottom of the delivery head chassis. e. Using a slotted screwdriver, turn the air pressure adjustment screw on the control valve of the appropriate handpiece (counterclockwise to increase pressure, clockwise to decrease pressure) until the handpiece manufacturer's correct specification registers on the pressure gauge. Air Pressure Adjustment Screws 3. Repeat a. through e. in Step 2 to set the pressure for each handpiece. NOTE: If a low-speed handpiece is required, slide the coolant air and water restrictor over the lines on the appropriate control valve. Flush Valve axcs Basic-Duo CMU 1. Remove the handpiece from its holder. 2. Activate the flush toggle valve. 3. Operate each handpiece for 30 seconds into a sink or open vacuum line. Vacuum Accessories 1. Make sure the shut off valve located on the underside of the delivery head is in the OPEN position. 2. Evacuate one cup of water (8 oz. each) through the saliva ejector and the highvolume evacuator. Air/Water Syringe First depress the air button and then the water button to test the flow. Fiber Optics Options Follow the test procedures outlined in the instructions included in each fiber optic handpiece package. Chipblower If the foot control is equipped with an optional chipblower, a burst of air should be delivered to the handpiece when the chip air valve is depressed. NOTICE After all final testing is complete, install the USC cover using four #10 screws. 14 Installation, Operation and Care Manual

16 Section V Operation Delivery System The Basic-Duo CMU offers the following design features: Operation of two handpieces and a syringe. Drive air and coolant water may be adjusted individually for each handpiece. Foot control toggle valve allows wet or dry cutting. Master switch turns entire unit ON and OFF. Easy cleaning and disinfecting. Master Switch Controls The master toggle switch located in the rear of the delivery unit controls the ON/OFF function of air, water and electricity to the entire unit. Flip the toggle switch to the right to turn ON the unit. An automatic CUT OFF, can be demonstrated by placing tubing in the hanger and disabling operation for that position. The handpiece holder angle can be adjusted by using an Allen wrench to loosen two set screws and Handpiece Holder Set Screw rotating the holder to the desired angle; then retightening the screws. An oil collector/filter is designed to collect oil from the handpiece exhaust air. Periodically check the filter for cleaning or replacement by lifting the delivery head cover and removing the screws that secure the filter cover. Master ON/OFF Switch Oil Collector/ Filter IMPORTANT: At the end of each work day, and anytime the unit is unattended, make sure the master control switch is in the OFF position. Swing-Away Instrument Hanger This feature s design allows the following functions: The entire instrument hanger bar can be moved to the left or right to provide easy access to the optional tray on top of the delivery head. Grasp the delivery head with one hand; with the other hand, grasp the instrument hanger bar Rotate handle and move it to the left or right. Instrument Hanger Delivery Head Positioning The horizontal and vertical location of delivery head can be varied by doing the following: To vary the horizontal location, push or pull the instrument hanger bar handle. To raise or lower the delivery head, loosen the thumb knob, adjust the delivery head to the desired height, then retighten the thumb knob. Thumb Knob axcs Basic-Duo CMU 15

17 Section V Operation Coolant Water Spray Coolant water spray to all the handpieces can be turned ON or OFF using the toggle switch located on the foot control. The coolant spray volume is individually adjustable for each handpiece. CAUTION To prevent damage to the manifold, do not overtighten the water coolant valves. 1. Turn the coolant water adjustment knobs under the cover to engage the coolant valve. 2. While operating the handpiece, turn the knob counterclockwise to increase the volume of coolant water spray. To decrease the volume, turn the knob clockwise. NOTE: The adjustment tool can be sterilized. Air Pressure Handpiece Coolant Water Adjustment Knobs Air pressure to each handpiece can be adjusted to the manufacturer's specifications by following the air pressure instructions in Section IV Testing under the heading Air Pressure on Page 14. NOTE: These procedures must be done while: The master switch is in the ON position, The handpiece is out of its holder and The foot control is fully depressed. WET/DRY Toggle Valve Disc axcs Basic-Duo CMU NOTE: When making necessary air pressure adjustments, refer to the air pressure gauge located at the front of the delivery head to check the approximate amount of air pressure delivered to the handpiece. Flush System It is recommended that the tubing of each handpiece used be flushed after each patient. 1. Hold the handpiece tubing over a sink or open vacuum line. 2. While facing the front of unit, move the FLUSH toggle Flush Toggle located at the rear of the delivery head to the left, and hold it there for 20 seconds. NOTE: Flushing the water line in the handpiece can be done by operating the FLUSH valve while either fully depressing or not depressing the foot control. Foot Control The speed of the handpiece is controlled by depressing the disc located on the foot control. A light pressure on the foot control disc causes a slow speed. Full pressure on the disc causes the handpiece to operate at full speed. NOTE: The coolant water spray ON/OFF function is also controlled by using the toggle valve located on the foot control as described above.
