Chair power is controlled by the Mains on/off button on the power supply. The on/off button provides power to the chair, as well as any attached modules (including delivery system, dental light, cuspidor, and other support systems). You can leave this button in the on position overnight, although you may choose to save energy and turn it off during longer periods of non-use. The power should always be turned off before service. To access the on/off button on chairs with a contoured floor box, first remove the front floor box cover (see Figure 2). Grasp the cover on both sides and pull up. If needed, use a large coin in the integrated coin slot to gently separate the contoured floor box cover from the frame. Then remove the power supply cover. CAUTION

Take care not to damage the cover when using the coin slot.

Touchpad Chair Controls Your touchpad chair controls (see Figure 6) work similarly to the footswitch. To use and program chair functions on your touchpad, please reference the Instructions For Use that came with your delivery system. Figure 6. A-dec Touchpad Examples

Note: Touchpad symbols are proprietary to A-dec Inc.

Patient Positioning Your chair features one of two choices of backrest: a thin-line back with patient-adjustable neck support or a thin-line back with double-articulating headrest.

Patient-Adjustable Neck Support Backrests with the integrated neck support cushion (see Figure 7) allow for easy adjustment by the patient or staff. When the patient is seated, ensure that the neck cushion is in the correct position. Place the cushion below the occipital bone for patient neck comfort. Properly positioned, the cushion glides with the patient to provide comfort as the chair is raised or lowered. Figure 7. Neck Support

Neck Support Cushion

86.0093.00 Rev C

Basic Operation 

The neck support can be repositioned in the track to accommodate shorter or taller patients (see Figure 8). To reposition, place your thumb against the neck support armature and pull the cushion out from the track. Flip the cushion around and snap back into the track. The cushion includes a graphic on the back that depicts proper orientation for shorter or taller patients. Figure 8. Reposition Neck Support Neck Support Track

Double-Articulating Headrest Backrests with the double-articulating headrest offer you exceptional flexibility in positioning the patient (see Figure 9 and Figure 10). Figure 9. Double-Articulating Headrest

Figure 10. Double-Articulating Headrest Positioning

Headrest Articulation The double-articulating headrest offers a “glide” feature, as well as manual articulation (see Figure 10). The locking knob allows you to easily adjust the headrest for a full range of positions. Release the headrest by turning the locking knob counterclockwise, then adjust the headrest for a proper fit. Lock the headrest in the desired position by turning the knob clockwise. For minor height adjustment, slide the headrest cushion up and down. For additional height adjustment, reposition the glide bar. When the glide bar has reached its maximum recommended working height, a warning will be visible on the patient’s side of the glide bar. Do not use the headrest in a position where this warning is visible. WARNING

Basic Operation 

How to Position for Wheelchairs The double-articulating headrest can be used to accommodate patients in wheelchairs, as shown in Figure 11. Figure 11. Positioning for Wheelchairs

To position the headrest for wheelchairs: 1. Slide the headrest glide bar up until it is free from the dental chair. 2. Rotate the headrest 180° and slide the glide bar into the backrest. Ensure that the glide bar is pushed completely into the backrest. 3. Position the dental chair to its full back-up position. 4. Once the headrest is repositioned, adjust the height by moving the dental chair up or down. The patient should be positioned so the wheelchair and the dental chair are back to back. 5. Ensure that the wheels of the wheelchair are locked.

Two-Position Armrests The armrests allow the patient to easily access the chair. Pull or push the armrests to reposition them in the forward or back position (see Figure 12). Figure 12. Positioning Armrests

The armrests can also be locked into the upright position (see Figure 17 on page 12).

ADJUSTMENTS AND MAINTENANCE

Removing Upholstery The design of the upholstery makes removing and replacing it quick and easy. The upholstery on your chair is installed in three sections: back, seat, and headrest.

Back Upholstery To remove the back upholstery, firmly grasp the bottom edge of the cushion and lift upward (approximately 1" or 25 mm), then lift the upholstery away from the chair back (see Figure 13). To reattach the back upholstery, place the key holes on the armature over the large fastener heads then push down until the upholstery stops. Figure 13. Removing the Backrest

Fastener Heads

86.0093.00 Rev C

Adjustments and Maintenance 

Seat Upholstery To remove the seat upholstery, pull the pins out on both sides of the seat armature (see Figure 14). Then lift the seat and move it away. Figure 14. Removing Seat Upholstery Armature

Pin Ring

When replacing the upholstery, ensure the pins are completely in place. The pin ring should be flush with the seat armature. CAUTION

Double-Articulating Headrest Upholstery To remove the headrest upholstery, position the headrest to access the two screws on the back, loosen screws with a 1/8'' hex key, and remove upholstery (see Figure 15). To reattach the headrest upholstery, position the headrest to access the screws, place the upholstery on the headrest, insert and tighten the screws. Figure 15.

Headrest Glide Bar Tension If the headrest drifts downward, or if it is difficult to move up or down, the glide bar tension can be adjusted. To adjust the tension, use a 1/8'' hex key and turn the tension adjustment screw clockwise to increase friction or counterclockwise to decrease friction (see Figure 16). Figure 16. Drift Adjustment

Convert to Fixed Armrests The armrests can be locked in an upright position. Using a 3/16'' hex key, remove the rotational stop screw from the front of the armrest and install it in the back of the armrest (see Figure 17). Figure 17. Fixed Armrests Stop Screw in Front for Adjustable Armrests

Adjustments and Maintenance 

Utilities Utilities are located in the floor box. The location will depend on your specific delivery system configuration and facilities. For chairs with a contoured floor box, grasp the cover on both sides and pull up (see Figure 18). If needed, use a large coin in the integrated coin slot to gently separate the contoured floor box cover from the frame. CAUTION

Take care not to damage the cover when using the coin slot.

Asepsis Recommendations Touch and Transfer Surfaces Touch surfaces are areas that humans contact and are potential cross-contamination points during dental procedures. Transfer surfaces are areas that contact instruments and other inanimate objects and are potential cross-contamination points. A-dec recommends barrier protection for all applicable touch and transfer surfaces. Cover-All barrier film or any other barrier film produced under FDA good manufacturing practices, is suitable for this application. Refer to your national regulatory authorities for barrier recommendations specific to your location. Remove and discard barrier plastic after each patient treatment. BIOHAZARD

For touch and transfer surfaces where barrier protection is not applicable or when barriers are compromised, refer to the A-dec Equipment Asepsis Guide (p/n 85.0696.00) for recommendations on proper cleaning and chemical disinfection.

Toeboard Cleaning To remove scuffs, scrapes, and stains from the non-upholstered portion of the toeboard, follow these steps: 1. Remove the vinyl toeboard cover. 2. Wet the foot area with water from a spray bottle or wet towel. 3. Apply a mildly abrasive kitchen or bath cleanser. Follow the manufacturer’s instructions. 4. Use a soft towel to rub the cleanser in a circular motion over the entire surface. 5. Remove the cleanser with clean water and a clean towel. This process may be repeated for blemishes that require additional cleaning.
