Theory of Operation
The Advanced Delivery System is a pneumatically controlled system that uses standard compressed air for operation of dental
tools and accessories and for pressurizing a closed water supply. The system uses air pressure from a foot control to operate
air driven tools.
Closed Water System
The Closed water system uses a single one liter plastic bottle designed for holding pressure. The bottle can be filled with clean
tap or distilled water for the source of water supply to the dental drills and air/water syringe. The system works by supplying
compressed air regulated to 35 psi which pressurizes the water within the bottle and forces it up through a plastic pick up
tubing in the bottle.

Quick Start Up List
The operator is expected to fully read and understand all aspects of the operation manual for operation of this dental system.
The following is a brief condensed highlight of steps to use the system.
Verify Mechanical Integrity and Safe Use – After unpacking the unit, look for any damage that could affect safe and
proper operation. Ensure there are no missing parts or accessories. Carefully inspect components for tightness and the
absence of cracks, excessive wear or frayed electrical cords. If there is any adverse damage or the lack of mechanical integrity
that would prevent the safe use or operation of the system, it should not be used until repair or replacements correcting the
defects are made.
Verify Handpiece Placements – Ensure all handpieces are placed into their correct holders and that the corresponding
tubing is correctly situated. This system uses auto holders that activate the instrument once it is removed. If any instruments
are incorrectly placed into holders, the selected instrument by the operator will fail to work. Quick Check – Verify all tubings hanging straight
down are not crossed and are placed in sequential order from left to right on the holder bar. This will ensure they are placed correctly.
Verify Holder Switches are Active – The auto handpiece holders feature a lock out switch levers which can be used to
disable function of that instrument if desired by the operator. Ensure all these levers are pointing straight down towards the
floor to ensure all holders are set to active. Otherwise an instrument may fail to operate when removed from the holder.
Verify Water System – Check and or fill water bottles appropriately and ensure the air pressure switch is turned on and that
air pressure in the gauge reads approximately 30-35 psi.
Verify Handpiece Operation – Handpiece instruments can be picked up and operated briefly by pressing the foot control.
Verify fiber optic illumination systems light and operation of other instruments. Water can also be sprayed from instruments to
ensure it is working correctly.

1.5 Unpacking and Setup
Carefully remove all packaging material from around and underneath the unit and remove the accessory box, which may
contain additional items required for installation. Inspect the unit for any obvious signs of shipping damage. If any damage is
discovered, immediately contact our Customer Service Department at [phone] or [phone].
Roll the unit to its location on a level surface. Place the handpiece tubings, air/water syringe, and optional instruments (if so
equipped) into their respective holders. Position the foot control and tubing on the floor toward the front of the unit.
Locate the clean water system on the side of the system. Fill the bottle with clean water or other approved solutions. Please
refer to Closed Water System for more information.
The cart then needs to be connected to a central air supply, appropriate electrical supply and optional vacuum and water
supply. Connection of umbilical lines from the cart to an appropriate junction box are the responsibility of the user and should
only be performed by knowledgeable individuals. The tubing is color coded and the wiring is numerically indicated and color
coded to assist with connection. Please see Pipe Junctions - Housings and Concealment for information on the umbilical
junction box connections. If the cart is connected to a plumbed water supply, the water pressure must be regulated to 35 psi
or less.
1.6 Electrical Installation
The system is equipped with a high grade safety rated power cord and plug. By design, the plug is to be placed into a
standard 115 volt 60 Hz outlet. Generally, contractors will provide a duplex or quadplex box that can be floor or wall
mounted. For systems shipped outside of North America with 230 volt 50 Hz service, you will need to supply the correct plug
per your country’s electrical code.
IMPORTANT REQUIREMENT: Due to the sensitive nature of the electrical components installed in the system, the electrical
supply should be made to a dedicated AC circuit with an isolated ground to provide line noise rejection and computer-grade
electrical current.
1.7 Compressed Air
The system is provided with a standard dental air line for supplying compressed air
to the system.
The air line is 1/4” outside diameter (O.D.) and has a 1/8” inside diameter (I.D.).
The system also includes a combination master air supply assembly with regulator
and internal air filter, and a standard angle stop with a manual shut-off valve. The
angle stop has a 5/8” compression fitting inlet to connect onto 1/2” copper pipe
which must be installed by a licensed plumber. The outlet of the angle stop has a
3/8” compression fitting to accept the connector from the master air supply. Air
supplied to the system should be oil-free and regulated to a standard dental unit
pressure of 75 to 80 psi. The 1/4” air line is connected directly to the master air
supply assembly.
1.8 Water Supply
All systems include a Closed Water System standard. There is no need to connect to municipal water lines. To optimize
infection control, connecting to municipal water is not recommended. If this option is still desired, connection to city water can
be provided by requesting a selector switch (Model 9776) to connect between city water and bottled water.

1.9 Optional Suction Connections and Piping Recommendations
ASI supplies suction line tubing made from a special grade of material that is inert to common
caustic irrigants and disinfectants used in dentistry. The suction tubing has a 5/8” inside
diameter (I.D.). Included with suction packages are PVC adapters to connect the 5/8” tubing to
either 1/2” or 3/4” PVC pipe (see Figure 1.9). If using 1/2” copper pipe for suction, the tubing
can simply be slipped over the pipe and clamped into place.
RECOMMENDATION: PVC pipe is recommended for suction plumbing lines and NOT copper,
as the copper can corrode from some of the caustic irrigating and disinfectant solutions used
in dentistry, such as sodium hypochlorite. Check your local building codes to see which piping
materials may be used for suction lines.
1.10 Pipe Junctions -Housings and Concealment
It is recommended to cover the area where the pipe stubs and
connections are made to prevent them from being bumped into and
to conceal them within the operatory. If a computer or monitor will be
attached to the delivery system, it is advisable to have network cables
run through the same area as the plumbing to manage all the various
tubing, wires and cables. An optional junction box housing is available
from ASI (see figures 1.10A an 1.10B).
This allows the plumbing and electrical to run within the wall between
two studs. A decorative trim panel is then placed over the wall with
cut-outs for the umbilical lines. The location in the wall should be
approximately 12” to 18” off the floor and should be near where the cart will be placed.
