How to Operate Your Chair
The A-dec 500 dental chair is a hydraulically controlled dental chair providing a balance between patient
comfort and doctor efficiency. The ease of operation and patient access was designed based on direct input
from practicing dentists and hygienists.
Power On/Off Button
The Power On/Off button is located on the base of
the chair. This function allows you to engage power or
disengage power to the entire system at the touch of
a button. When the button is pressed in, the system
has power. When the button is out, the system has no

How to Adjust Your Chair
The following detail talks about the components that
you can use to adjust your 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 engage the brake, push the brake lever firmly to
the left. To release the swivel brake, push the brake
lever to the right.

2
Engaged
If the chair swivels left or right with the brake
engaged, or if it is difficult to move with the brake
disengaged, adjust the swivel brake tension
(see Figure 5). To adjust the tension, use a hex key and
turn the tension adjustment screw clockwise to
increase brake friction or counterclockwise to decrease
brake friction.

The air vent (the open end of the “T”fitting)
prevents air from being trapped in the office waste
drainage system. If the vent becomes obstructed,
waste water and debris may back up into the unit.
If a cuspidor is included with your unit, a flexible tube
from the cuspidor will be connected to the gravity
drain.

System Air and Water Pressure Adjustments
The air and water pre-regulators are located in the floor box. Before making any adjustments, verify that the
air compressor is turned on, and that it maintains 80–100 psi pressure in the tank. If it doesn't, refer to the
compressor instructions.
NOTE: When decreasing system air or water pressure, you will not see the air pressure gauge in the floor
box change until the pressure from the system is relived. Activate the syringe for a few
seconds, then check the gauge. Repeat this process each time you make an adjustment to decrease
pressure.
The table explains how to adjust the air and water pressure.
Table 5
Step
Steps for adjusting air and water pressure
Action
1
Fully open manual shutoff valves (counter-clockwise).
2
Turn the system ON and check the pressure gauge in the floor box (see Figure 15).
Air pressure should be 70-80 psi.
3
While watching the gauge, operate the syringe. If the system air pressure drops by more than 15
psi, check for clogged filters (see Figure 17).
4
If adjustment of the air or water pressure is required, turn the appropriate pre-regulator knob
clockwise to increase pressure, or counterclockwise to decrease.

How to Check for a Clogged Air Filter
To check for a clogged air filter, flip the master On/Off
toggle to the ON position and remove the floor box
cover. While watching the air pressure gauge in the
floor box (see Figure 15), press the syringe air button.
If the air pressure indicated by the gauge drops by
more than 15 psi, the filter
element is clogged and must be replaced.

4 - Beveled edge
Figure 17
Air or Water Filter Replacement
Inspecting the Filters
To inspect or replace a filter element, flip the master
On/Off toggle to the OFF position, then close the
manual shutoff valves. Bleed the system of air and
water pressure by operating the syringe buttons until
air and water no longer flow. Using a
standard (flat-blade) screwdriver, remove the filter
housing from the air and/or water regulator
assemblies (see Figure 17) and remove the filter. If the
filter is visibly clogged or discolored, you will need to
replace it.
When installing a new filter, notice that one end
of the filter has a beveled edge. Install the filter with
the beveled edge facing the manifold
(see Figure 17).
NOTE: The system will not work properly if the
filter is installed incorrectly.
