This section includes basic operating instructions for your A-dec 500 delivery system. For
touchpad operation, refer to “Touchpad Controls” on page 9.
Power
The delivery system has two power on/off locations: (1) the power on/off button on the
chair, and (2) the master toggle on the right side of the control head.
Master Toggle
The master toggle controls the power to the delivery system as well as other modules
mounted to the chair. Flip the toggle to turn the system on or off.
To prolong the life of your equipment, turn off the master toggle when the delivery
system is not in use.

A-dec 500 Delivery Systems Instructions For Use
Handpiece Activation
To prevent damage to your delivery system, do not use saline solution,
mouth rinses, or any chemical solutions not specified in this guide. Use a water
supply system separate from your delivery system if you need to use these types of
solutions. As a general rule, you can use drinking water as source water in your
delivery system.
CAUTION
For complete instructions on water usage in your A-dec systems, refer to the
A-dec Self-Contained Water System Instructions For Use (p/n 86.0609.00) included
with your equipment.
The handpieces automatically activate when you lift a handpiece from its holder or pull the
Continental whip forward. Press the foot control to operate the activated handpiece.
Foot Control
The foot control regulates drive air to the active handpiece. It provides an air signal that
activates air coolant and water coolant flow. The foot control is equipped with a wet/dry
toggle and a chip blower/accessory button (see Figure 6). To turn the water coolant on or off,
use your foot to flip the wet/dry toggle.
NOTE The foot control has additional functionality when used with a deluxe touchpad or an
intraoral camera. The wet/dry toggle operates as a three-way switch with the air and water
coolant buttons on the touchpad.
Figure 6. Foot Control
Chip Blower/
Accessory Button
Wet/Dry Toggle
Chip Blower / Accessory Button
The chip blower/accessory button operates as either a chip blower or an accessory button (see
Figure 6). The chip blower function sends a jet of air through the handpiece without
activating the handpiece bur.
The accessory button function operates integrated accessory devices. For more details, see
your authorized A-dec dealer.

Basic Operation
Chair Lockout
The lockout feature inhibits the operation of the dental chair when you remove a handpiece
from its holder and step on the delivery system foot control. To resume normal chair
operation, lift your foot off of the foot control disk.
Flexarm Brake
The flexarm brake will hold up to 8 lb. [3.6 kg] of weight on the control head. The thumbactuated brake restricts vertical movement but allows for side-to-side horizontal positioning
of the control head (see Figure 7).
Figure 7. Flexarm Brake
Touchpads
The A-dec 500 delivery system touchpads centralize treatment room controls into one touch
surface. Some touchpad buttons have indicators to alert you if the operation is functioning.
For complete instructions on touchpad operation, see “Touchpad Controls” on page 9.
Accessory Holder
The optional accessory holder is a convenient location for additional accessories like a curing
light or intraoral camera. The holder installs on the right or left side of the control head in the
unused touchpad position (see Figure 8).

A-dec 500 Delivery Systems Instructions For Use
Air and Water Manual Shutoff Valves
Shutoff valves control the air and water to the unit. To prevent leaks, these valves should
remain fully open (turned counterclockwise) except while your unit is being serviced.
Air-Actuated Air and Water Shutoff Valves
The air-actuated air and water shutoff valves automatically shut off air and water to the
system when the master toggle is in the Off position. This safety feature prevents water
damage in the event of a water leak while the unit is unattended.
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.
To adjust air or water pressure:
1. Fully open manual shutoff valves (counterclockwise).
2. Turn the system on and check the pressure gauge in the floor box (see Figure 30 on
page 29). 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 31).
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.
Air and Water Filter Replacement
Air and water pass through separate filters before entering the regulators. Replace a filter
when it becomes clogged and causes restricted flow (see Figure 31).

Barrier Protection
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 crosscontamination points during dental procedures. Transfer surfaces are areas that come into
contact with instruments and other inanimate objects.
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.
CAUTION
If you use barriers, always replace the barrier film after each patient.
