NOTE The non-locking retainer assembly is not appropriate for use as a cheek retractor because it allows the syringe tip to rotate.

Your syringe tip rotates to spray in different directions. However, if you use your syringe tip for cheek retraction and you have the hex-shaped retainer nut, you may adjust the nut so the tip does not rotate easily. 1. Install the syringe tip. See “A-dec Syringe Tip” on page 14. 2. Use the plastic wrench provided with the hex nut to tighten the hex nut. Ensure that the tip does not rotate easily. Tightening a hex retainer nut on an improperly installed syringe tip crushes the internal collet, making removal of the syringe tip difficult and installation of a new tip impossible.

Disconnect the Syringe

Sterilization

1. Turn off the master toggle.

Follow these steps to sterilize the syringe and syringe tip:

2. Press the syringe air and water buttons to relieve the system air and water pressure. 3. Unscrew the syringe handle until the syringe head separates from the syringe terminal. When the syringe is disconnected, any water remaining in the syringe head drips out. Before disconnecting the syringe on units without a quick-disconnect syringe terminal, remove the self-contained water bottle. If the water bottle is located above the height of the syringe, water can drain out of the tubing.

CAUTION

Syringe Asepsis All syringe tips are considered critical items and must be heat sterilized after each use. A-dec has designed syringes and syringe tips to be autoclavable or heat sterilized. Remove the syringe and syringe tips from the delivery system for sterilization. Disconnect the Syringe 1. Turn off the master toggle. 2. Press the syringe air and water buttons to relieve the system air and water pressure. 3. Unscrew the syringe handle until the syringe head separates from the syringe terminal. When the syringe is disconnected, any water remaining in the syringe head drips out. Precleaning

1. Rinse the syringe and syringe tips in clear water. 2. Flush the tips with isopropyl alcohol or Harvey’s Vapo-Steril. Heat sterilize the syringe and syringe tip using a steam autoclave for at least 4 minutes at a dwell temperature of 273°F (134°C). Sterilizing equipment at higher temperatures reduces the O-ring lifespan.

CAUTION

Syringe Flow Adjustment The syringe air and water flow are controlled by a dual pinch valve located inside the control head. To identify which adjustment screw controls the air flow and which controls the water flow, follow each length of tubing through the dual pinch valve. The syringe air tubing is connected to the air filter regulator manifold, and the syringe water tubing is connected to the red tubing inside the control head. Air Filter Manifold

Handpiece Tubing Flush System Your handpiece control system in equipped with A-dec’s handpiece tubing flush system. The system flushes more water through the tubings in less time than is normally possible when operating the foot control only. The handpieces should not be connected when flushing the tubings.

How Often Should I Flush the Handpiece Tubings? At the Beginning of Each Day Flush the tubings for 2-3 minutes. After Each Patient Flush the tubings for 20-30 seconds.

Flushing the Handpiece Tubings 1. Locate the handpiece flush toggle on the underside of the control head.

3. Move the flush toggle to the on position and hold for the appropriate time required, either for flushing between patients or flushing at the beginning of the day. Water flows only as long as you hold the toggle in the on position. 4. Replace the handpiece tubings in their holders.

Self-Contained Water System How to Choose Treatment Water The correct water to use in the A-dec self-contained water system depends on the quality of your municipal water. It’s important to choose a source that consistently provides good water quality. For guidance, refer to the regulations specific to your location. • Tap Water - If you have confidence in the quality of your municipal water supply, consider using tap water in your self-contained water bottle. • Bottled Water - If you have concerns about the quality of your municipal water supply, use bottled water from a commercial source.

Handpiece Flush Toggle 2. Gather up all the handpiece tubings that use water coolant and hold them over a water receptacle. Be sure you hold the tubings so that the water will be directed away from you and into the receptacle.

• Softened Water - In areas with hard water, greater than 200 mg/L as calcium carbonate (11.7 grains per gallon, 2.0 mmol/L), A-dec recommends the use of a water softener to prevent the buildup of mineral deposits that may impact the functionality of your delivery system.

Water Bottle Removal and Installation Follow these procedures to properly remove, refill, and install an A-dec self-contained water bottle: 1. Use the master toggle to turn off the system. 2. Turn the bottle counterclockwise until the air seal breaks. 3. Remove the bottle by continuing to turn it counterclockwise. 4. Empty any remaining water from the bottle. 5. Wash your hands with soap and water, and wear new gloves before handling, filling, and installing the water bottle. 6. Drop an A-dec ICX® waterline treatment tablet into the bottle and fill with treatment water. Follow the instructions that appear on the ICX packaging.

7. Install the bottle by aligning it with the water bottle cap, making sure that the pick-up tube extends straight down into the bottle. Screw the bottle onto the cap until it is secure.

Operating Your Steril-Vac Air is supplied by attaching the quick-disconnect (QD) tubing to the steril-vac QD. AVS Handpiece

Steril-Vac QD Do not overtighten the water bottle or you may damage the components. It is normal to hear a pressurization sound after the system is turned on.

CAUTION

8. Turn on the system. Air fills the bottle. 9. Operate the syringe and handpieces to clear any air from the water system.

Waterline Maintenance A-dec recommends a three-part protocol to maintain good water quality in your system: shock treatment, regular dental unit water monitoring, and the continuous use of A-dec ICX waterline treatment tablets. Use treatment products that are registered with the U.S. Environmental Protection Agency (US EPA). If you’re located outside the U.S., contact your authorized A-dec dealer for product recommendations that are compatible with A-dec equipment. Follow the instructions that appear on the ICX packaging. For complete details on water usage in your A-dec system, see the Waterline Maintenance Guide (p/n 85.0983.00), which is available in the Document Library at www.a-dec.com. IMPORTANT

Steril-Vac Your A-dec Steril-Vac eliminates the need for a central vacuum. It is an air operated oral evacuation system using A-dec’s air vacuum system (AVS) handpiece. Vacuum created at the handpiece forces the debris into the one-quart (.95 L) waste container. An optional two-quart (1.9 L) waste container is available.

18

Actuation Button Supply Air Tubing QD

Waste Container

To actuate the vacuum, press and hold the button on the AVS handpiece. The button is spring loaded to the Off position.

Cleaning the Steril-Vac After each patient, thoroughly rinse the Steril-Vac by drawing clean water through the AVS handpiece. After rinsing, draw air through the system for a few seconds to clear all water from the tubing. NOTE Vacuum-lines should be cleaned at the end of each day by evacuating a detergent or water-based detergentdisinfectant through the system.

If you use barrier film to protect the main body of the AVS handpiece, replace the barrier film after each patient. Clean and disinfect this instrument at the end of each day or after each patient if the barrier film has been compromised. If you do not use barrier film, or if you perform oral surgery, always clean and disinfect the instrument after each patient.

Disinfection

Daily AVS Handpiece Cleaning

To disinfect the AVS handpiece without disconnection from the vacuum system:

Daily cleaning of the AVS handpiece is necessary to prevent accumulation of debris. Several special cleaners with disinfectant properties for dental vacuum systems are available from dental supply dealers. If you use one of these cleaners, be sure to follow the manufacturer’s recommendations. Never use a sudsing detergent to clean the AVS handpiece.

1. Remove the vacuum tip from the AVS handpiece. 2. Disinfect the AVS valve body assembly by using an intermediate-level disinfectant according to instructions for the disinfectant; A-dec recommends a phenolic (dual) water-based disinfectant.

4. Operate the AVS handpiece valve several times to verify that it rotates smoothly.

Use the brush provided in the field repair kit to clean the AVS handpiece. Push the brush all the way past the cross tube to clean the lower portion of the AVS handpiece. Rinse with clean water, and then hold the button down until all the water has been purged from the tubing.

Disposable Tips

Steril-Vac Waste Container

Heat sterilize stainless steel AVS tips after each use. If you are using disposable AVS tips, replace them with new tips after each use.

The Steril-Vac waste container should be cleaned and disinfected each time it is emptied.

3. Follow the manufacturer’s instructions for disinfectant contact time.

Disposable AVS tips are not sterilizable and should not be reused.

CAUTION

DANGER Infectious waste may be present. Follow asepsis protocol to prevent cross contamination.

Sterilizable Tips To clean and sterilize a stainless steel AVS tip: 1. Remove the tip from the AVS. 2. Clean and rinse the tip using a mild detergent and water, then allow the tip to dry completely. 3. Sterilize at 132-134°C (270-273°F) for 4 minutes in a pre-vacuum sterilizer or at 132-134°C (270-273°F) for 6 minutes in a gravity displacement sterilizer.

A-dec Pac I (Portable) Model 3420 Instructions for Use and Maintenance

Oil Collection System

Care Instructions

The gauze pad (2" x 2") inside the oil collector jar on your unit needs to be changed once a week for normal usage. Change it more often for heavy use.

For recommended asepsis instructions, refer to the A-dec Equipment Asepsis Guide (A-dec p/n 85.0696.00).

1. Remove the oil collector jar from the unit and discard the old gauze. 2. Fold in quarters a new two-inch square gauze pad and place against the spring inside the jar. 3. Screw the oil collector jar onto the unit. Do not overtighten.

Barrier Protection A-dec recommends barrier protection for all applicable touch and transfer surfaces. Touch surfaces are areas that come into contact with hands and become potential cross-contamination points during dental procedures. Transfer surfaces are areas that come into contact with instruments and other inanimate objects. In the USA, barriers must be produced under the Current Good Manufacturing Practice (CGMP) as specified by the U.S. Food and Drug Administration (USFDA). For regions outside the USA, refer to the medical device regulations specific to your location.
