This document contains installation instructions for the A-dec 300 system.

Before you begin:

• Clear the room of all debris and thoroughly clean the floors.

• Check that manual air and water shut-offs are installed.

• Purge any debris from air and water lines.

• Check with local building and code authorities about installation requirements. They differ from state to state and internationally.

Your installation may not require all components described in this document. Before you begin:

Anchor the Chair

Use the lag screw or masonry anchor with the cleat to anchor the chair to the floor. Select the procedure for your type of flooring structure.

WARNIN G Anchoring the chair to

the floor is required for mechanical stability. Failure to anchor properly could result in damage, serious injury, or death.

CAUTION Check the flooring

and/or framing material where you will anchor the chair. If it is not at least 3-1/4" (82 mm) thick, contact a licensed contractor about reinforcing the floor.

1. Place the support center post in the chair-

base mount with the notched bottom over the screw near the base of the mount.

NOTE If you have a post mount

system, the support center post installs into a chair adaptor instead of the chair-base mount and the post does not have notches in the bottom.

WARNIN G If you’re installing a

post mount system, anchoring the chair to the floor is required for mechanical stability. Failure to anchor properly could result in damage, serious injury, or death.

Figure 14. Install the Support Center Post

If the support center is installed to the left of the patient, face the square hole away from the chair. If the support center is installed to the right of the patient, face the square hole toward the chair.

2. Place a level vertically against the post

and align it with the four leveling screws near the top of the chair-base mount.

NOTE If you have a post mount

system on an A-dec 511 chair, the chair adaptor has eight leveling screws.

4. Once the post is level, evenly tighten the

leveling screws to secure it.

NOTE This is the initial leveling of

the post. The system requires a final level after everything is installed. For final leveling instructions, see “Level the System” on page 77.

Install the Support Center

1. Wrap the support center tubing bundle

around your arm and lift the support center out of the box.

2. Remove the covers from the support

center.

3. Place the support center over the support

center post with the water bottle connection toward the toe of the chair.

CAUTION Be careful to clear all

wires and tubing so they stay on the open side of the support center frame and do not get pinched or kinked.

4. Slide the support center down the post

until its frame rests on the support screws on the support center post.

5. Align the support center depending on

the configuration of the system:

○ If you have an A-dec 300 system that

includes a cuspidor, align the support center so the positioning guide clears the armrest. Use the jumper and test points to move the chair up and down when testing clearance.

WARNIN G The positioning

guide must clear the armrest to provide the proper clearance of 1-1/8" (29 mm) between the cuspidor bowl and armrest.

○ If you have a base mount system

without a cuspidor, or a post mount system, align the support center so it is parallel to the dental chair.

NOTE If you have a post mount

system, you are finished installing the support center. Skip to the note after step 9 for instructions on routing tubing and wiring.

7. Use a 5/16" hex key driver to install each

of the two 1-1/2" socket head screws until they are touching the back of the holes in the support center post.

8. Alternately tighten both socket head

screws until they are firmly secure (use approximately 13 ft-lb. [1.8 m-kgs] of torque). While tightening the screws, ensure the positioning guide retains its clearance of the armrest.

9. Route the support center tubing and

wiring through the chair-base mount into the utilities area at the base of the chair.

separate the power cables and data line from the tubing group and route them from the support center, underneath the mount, and down the lift arm to the power supply. Route the rest of the tubing bundle through the convolute into the remote floor box.

For information about installing the remote floor box, see “Install the Remote Floor Box” on page 39.

CAUTION Once you’ve completed

installing the support center, verify that the end of the cuspidor ventilation tube is 1/2" (13 mm) above the support center frame. This ensures that the cuspidor drains properly.

Install the Moisture Separator (Optional)

To install the moisture separator, use the directions included in the moisture separator kit (p/n 41.1477.00); then see “Connect the Utilities” on page 40.

Table 5 lists and defines the touchpad screen icons for endodontics mode.

CAUTION The A-dec|W&H

endodontics attachments have special features due to their ball-bearing design. Their life-long efficiency factors are stable and known; therefore, the A-dec endodontics system is able to control and display file torque very accurately. All other attachments have unknown life-long efficiency factors and therefore stated torque values are approximate.

Adjusting this setting for one handpiece changes it for all handpiece settings. This icon is displayed within the Forward/Reverse indicator.

Auto-off — The motor shuts off when the file speed reaches the torque limit.

Auto-reverse — The motor stops and reverses direction when the file reaches the torque limit.

Auto-forward — When the file reaches the torque limit, the motor stops, reverses three turns, then changes back to forward again.

Note: If the file is stuck, this cycle repeats three times before the motor stops.

2. If the system includes a delivery system and light, position them over the support center.

3. Rotate the support center until the positioning guide properly clears the armrest.

4. If the system includes a delivery system, pull its rigid arm toward the screws until the ribs on the support center frame are flush against the support center post.

5. Use approximately 13 ft-lb. [1.8 m-kgs] of torque to tighten the button head screw.

6. Alternately tighten both socket head screws until they are firmly secure (use approximately 13 ft-lb. [1.8 m-kgs] of torque).

7. Raise and lower the chair to check that the positioning guide clears the armrest.

8. If the guide does not properly clear the armrest, repeat steps 1 through 8.

9. Verify that the support center is level. If it needs to be adjusted, complete the steps in “1. Level the Support Center” on page 77.
