How do I turn on/off the power on chairs with delivery and support systems?

If you have a chair with an attached system, use the master toggle to turn on the power, water, and air. The master toggle is normally located on the delivery system, but may instead be located on the support center or floor box on chairs without a delivery system. If there is no power to the system, verify that the power button on the chair is pressed in. This button must be on in order for the master toggle to control system power.

What safety features are included in A-dec dental chairs and systems?

A-dec dental chairs and systems include safety features (like the chair stop plate) that may stop or prevent the chair from moving.

---

Why might the chair stop unexpectedly or not move?

This may occur due to any of the following:

• There’s an obstruction under the chair or attached module.
• The foot control disc or lever is pressed.
• A handpiece isn’t properly seated in its holder.

---

What should I do if the chair stops unexpectedly or won’t move?

Check for and correct any of the conditions listed above. If an obstruction is blocking chair movement, use the touch control or footswitch to raise the chair, then remove the obstruction.

---

How do I position the chair with manual controls?

Press and hold the appropriate icon/button to move the chair:

• Back Up: Press and hold to raise the chair back.
• Back Down: Press and hold to lower the chair back.
• Base Up: Press and hold to raise the chair base.
• Base Down: Press and hold to lower the chair base.

---

Is there anything important to know about using the manual controls?

A-dec touch controls and the footswitch move the chair in the same manner. For information about your touch controls, see the user support materials included with your delivery system. Ensure that the patient is positioned safely before using the manual or preset chair controls. Never leave the patient unattended while the chair is in motion. Always take extra care with small children and patients with limited mobility. To stop the chair at any point during preset movement, press any chair positioning button on the footswitch or touchpad.

---

How do I adjust the maximum height of my chair?

Contact your local authorized A-dec dealer.

How do I customize the X-Ray/Rinse chair preset?

The factory preset s moves the chair and patient into an upright position for x-rays or cuspidor access. A second press of s returns the chair to the previous position. You can also set s to function as a customized chair preset position. To change its function:

1. Press p and s at the same time and hold for three seconds. One beep indicates s is set as another customizable chair preset button. Three beeps indicate that s is set as the x-ray/rinse factory preset (which toggles between the x-ray/rinse position and the previous chair position).
2. If you set s as another customizable chair preset and want to assign a different chair position, follow the steps outlined above in “Customize the Chair Preset Positions”.

---

What are the factory settings for the preset positions?

The factory settings for the preset positions are:

• r Treatment 1: Positions the chair base and back down.
• q Treatment 2: Positions the chair base down and the back partially up.
• s X-Ray/Rinse: Moves the chair to either x-ray or rinse position. A second press moves the chair to the previous position.

---

How do I position the armrests?

Move the armrest out of the way to allow for easier patient entry/exit and improved operator access when working direct. Simply push or pull the armrest into position. On the A-dec 511flt chair, lift the armrest slightly to unlock, then lower it for easier patient entry/exit. Lift the armrest to return it back into the standard position. You can also rotate the armrest forward for easier operator access while working direct.

---

Is there a warning regarding armrest position?

Do not allow patients to drop their arms behind the armrests or under the backrest, or injury may occur when the chair moves.

---

How do I encourage a proper seating position for the patient?

To properly seat patients in the chair, ask them to sit as far back in the seat as possible. This ensures the best alignment with the lumbar support and comfort for the patient. For optimal comfort, patients can place their forearms on the armrests or keep their arms comfortably folded on their lap. Before the patient sits down in the chair, leave the headrest at a higher position. This will encourage the patient to sit all the way back in the chair. Adjust the headrest once the patient is seated to improve patient comfort and operator access to the oral cavity. For patients who require additional support to exit the chair, leave the armrests in the standard position.

---

How do I position the headrest?

The dual-articulating gliding headrest includes several features you can use to improve access to the oral cavity and increase patient comfort. Use the glide bar to accommodate a variety of patient heights. Simply pull up or push down on the headrest until it is in the desired position. The gliding headrest cushion provides additional height adjustment. You can easily adjust the headrest angle using one hand. Press the adjustment lever to position the headrest. Release, and the headrest holds its position.

---

Is there a warning regarding the headrest glide bar?

If the glide bar has exceeded its maximum recommended working height, a warning line will be visible on the patient’s side of the glide bar. Do not use the headrest in a position where this warning line is visible.

---

How do I position the headrest for wheelchairs?

To position the headrest for wheelchairs:

1. Remove the headrest from the dental chair.
2. Rotate the headrest 180° and slide the glide bar into the backrest until it stops.
3. Swivel the dental chair, if necessary, and position the backrest to its full upright position.
4. Position the wheelchair and the dental chair back to back.
5. Move the dental chair up or down, as needed, to adjust the headrest height.
6. Lock the wheelchair wheels.

---

How do I set the chair swivel brake?

The chair can rotate to any position within 30° either side of center. The chair swivel brake restricts rotation of the chair to keep the chair from moving during a procedure. To release the swivel brake, pull the brake lever to the right. To engage the brake, pull the brake lever firmly to the left.

---

How do I adjust the chair swivel brake tension?

If the chair swivels left or right with the brake engaged, or is difficult to move with the brake disengaged, adjust the swivel brake tension. Properly tensioned, the brake handle should be in the middle when it is fully engaged. To make the adjustment:

1. Move the brake handle to the right.
2. If the chair includes a back mount module, swivel the chair to access the adjustment screw. Use a 7/64" hex key and turn the tension adjustment screw clockwise to increase brake friction or counterclockwise to decrease brake friction. Only a small adjustment is needed to significantly increase or decrease tension.

---

How do I adjust the headrest glide bar tension?

If the headrest drifts downward, or if it is difficult to move up or down, the glide bar tension needs adjustment. To adjust the tension, use a 1/8" hex key. Turn the adjustment screw clockwise to increase tension.

---

How can I protect the touch and transfer surfaces?

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.

---

What are the regulations for barrier production?

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.

---

How can I extend the life of the upholstery?

To preserve the quality of your A-dec upholstery, use barrier covers instead of relying on chemicals. Barriers significantly extend the life of the upholstery and will help preserve its luxurious look and soft feel. To clean the upholstery, use a solution of mild dishwashing liquid and water. Use surface disinfectants only when the barriers have been compromised or there is visible spatter on the upholstery.

---

What should I know about the use and disposal of barriers?

For proper use and disposal of barriers, see the barrier manufacturer’s Instructions for Use.

---

What should I avoid when cleaning or disinfecting the upholstery?

Do not use household bleach (sodium hypochlorite) or other products containing chlorine, isopropyl alcohol (greater than 25 percent by volume), or hydrogen peroxide to clean or disinfect the upholstery. It can cause rapid deterioration and damage the product.

---

How do I access the utilities?

The chair utilities are located in the contoured floor box under your chair and typically include the electrical outlet, as well as the system hookups for air, water, and vacuum. To access, lift the cover up and off the floor box frame. For maintenance, contact your local authorized A-dec dealer.

---

Is there a warning regarding accessing the utilities?

Shock hazard. When you remove or replace the covers, take care not to damage any wiring or tubing. Verify that the covers are secure after you replace them.
