This document contains installation instructions for the A-dec 300 system.
Information that
is critical to a successful
and safe installation is
shaded like this note
throughout the guide.
NOTE
When
removing or replacing
covers, take care not to
damage any wiring.
Verify that the covers
are secure after
replacing them.
CAUTION
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:
1. Assess what modules you will install.
2. Use “Installation Sequence” on page 2 to note the order of the modules
that are to be installed.

could result in damage, serious
injury, or death.
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.

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.

WARNING 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.
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.

3. Use a 3/16" hex key to adjust the screws,
switching from one set of leveling screws
to the other until the post is level. Always
align the level with the screws you are
adjusting.
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
Figure 15. Position 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.

Be careful to clear all
wires and tubing so they stay on
the open side of the support

A-dec 300 System Installation Guide
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.
Figure 16. Ensure the Positioning Guide Clears the Armrest
Positioning
guide must
clear armrest.
Positioning
Guide
WARNING 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.

6. Use a 5/16" hex key driver to tighten the
button-head screw. While tightening the
screw, ensure the positioning guide
retains its clearance of the armrest.
Figure 17. Secure the Support Center
Button Head Screw
To ensure that the
button-head screw is properly
tightened, use approximately
13 ft-lb. (1.8 m-kgs) of torque.
CAUTION
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.
Use a 5/16" hex key driver to
apply 13 ft-lb (1.8 m-kgs) of
torque pressure to the screws.
Install two
1-1/2" Socket
Head Screws.
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.
Figure 18. Route the Support Center Tubing Bundle
NOTE If you are installing a
post mount system, remove the
Y-connector from the data line
before routing the tubing. (The
Y-connector is provided to
connect to multiple data
communication system devices.)
Route the tubing and wiring
from the bottom of the support
center through the convolute
into the remote floor box.
Utilities Area
If you are installing a post mount
system on an A-dec 511 chair,
Chair-Base Mount
86.0087.00 Rev F

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.
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 Post Hole Caps
Figure 160. Post Hole Caps
If the system does not have a delivery
system, dental light, or monitor, install caps
to cover the post holes for those modules:
• Support Center Post Holes: Use a
Phillips head screwdriver and a
6-19 x 1.2" screw to attach the trim cap
to the support center cover that does
not have the flow diagram.
• Intermediate Post: If the system has a
monitor mounted on the intermediate
post but does not include a dental light,
push the trim cap onto the end of the
intermediate post.
• Assistant’s Instrumentation Hub:
If the system includes an assistant’s
instrumentation mounted on a
telescoping arm but does not include a
delivery system, push the trim cap onto
the top of the hub.

2. Install the lower covers around the cover
ring. The indents on the side of the
covers go toward the bottom. The cover
with a hole goes over the chair-base
mount. If the support center is installed
to the right of the patient, use diagonal
cutters to widen the hole in the cover so
it will fit over the mount. Push the
covers' edges into the cover ring’s
grooves until they snap into place.

3. The upper support center covers attach
to the support center frame. For support
centers installed to the patient's left, the
cover with the flow diagram goes to the
outside of the support center frame,
away from the chair. For support centers
installed to the patient's right, this cover
goes on the side toward the chair. Insert
the small pins on the covers into the
holes in the frame and the larger pins on
the one cover into the connectors on the
other cover.

NOTE The Air Vacuum System
(AVS) is only available with A-dec
300 systems that include a
integrated floor box cover or a
remote floor box.
A
The AVS generates a vacuum using air
supply at 70 PSI minimum when a central
vacuum system is not available. It also
separates moisture and air that flows
through the system and discharges them
through a drain and air outlet.
B
NOTE You cannot have an AVS
without a cuspidor because the
cuspidor is required to mount the
switch that turns on the air flow
through the air saliva ejector.
