Unit Controls Description
All operating controls are located on the underside of the unit control head. This
location was chosen to reduce contamination via air-borne contaminants.
Dental Delivery System Control Head
Master On/Off Toggle
This toggle turns the unit on. It activates the air and
water shut-off valves which control the air and water
supplies to the delivery unit. The location of the toggle
is on the right underside of the unit head near the
center.
Shown with Optional Viewer
Always turn the Master On/Off Toggle to the “OFF”
position when the operatory is unoccupied. This will
ensure protection against damage resulting from water leakage from the delivery unit.
Air Coolant Control Valve
Control of coolant air to the handpiece is adjusted by turning the valve counterclockwise
to increase air flow, clockwise to decrease. The location of this valve is on the left
underside of the unit head near the center.
Water Coolant Flow Control Valve
Each water control valve adjusts the amount of water supplied to it’s handpiece. The
control valves are positioned to correspond with the handpiece layout. The location
of this valve is on the front underside of the unit head next to each corresponding
handpiece holder.
Handpiece Flush Control Toggle
This is a momentary toggle that flushes out the handpieces with coolant water when
activated. Hold the handpieces over cuspidor or other suitable container and activate
and hold the toggle for at least 20 seconds to flush out the handpieces. The location
of this valve is on the right underside of the unit head near the front.
Air Brake Button
The button is located on the end of the control head handle. The momentary valve
activates and releases the air brake in the control arm when adjusting the height of the
control head. Once it is placed in the desired position release the button to lock the
delivery system arm against vertical movement.
Handpiece Autoholders
Handpiece selection is automatic. The holders contain actuator valves that allow the
operation of the specific handpiece that is lifted from its holder, without the need for
a manual selector.

Dental Delivery System Cuspidor (Optional)
The Dental Delivery System cuspidors are equipped
with timed bowl rinse and manually actuated cup
filler. Both functions are controlled by buttons on
the top of the cuspidor housing.
Bowl Rinse Toggle
This momentary push button valve activates the bowl
rinse function. The bowl will rinse for 30 seconds
before automatically shutting off. This membrane
switch is located on the top left surface of cuspidor
near the center
Cup Filler Toggle
This momentary push button valve activates the cup filler, set to fill a 5 ounce cup
full. This membrane switch is located on the top right surface of cuspidor near the
center.
Wet / Dry Foot Control
Each dental unit is equipped with a variable speed, disc type foot control. Foot pressure
on any part of the disc controls the flow of air to the active handpiece. A signal relay
within the foot control simultaneously activates the air and water coolant.
Water Coolant On/Off Toggle
Or wet/dry toggle, interrupts the flow of water coolant to the handpieces when
performing a procedure that requires dry cutting.
Dental Delivery System Post-Mounted Utility Center
Water Flow Control Valve
This control valve adjusts the flow from the water outlet.
This control valve is located at the front of the utility center
above the city water switch and below the air and water
quick disconnects. Turn the knob counterclockwise to open
(increase) and clockwise to close (decrease).
Water Outlet
The water outlet accepts a 1/4" male quick disconnect
fitting. This fitting is located at the front of the utility
center above the Water Flow Control Valve on the left side
next to the Air Outlet.

Air Outlet:
The air outlet accepts a 3/8” male quick disconnect fitting. This fitting is located at
the front of the utility center above the Water Flow Control Valve on the right side
next to the Water Outlet.
City / Bottle Selector Switch
This toggle allows user to switch between city water supply and bottle water supply.
The toggle switch is located below the Water Flow Control Valve on the front of the
utility center.
Dental Delivery System Vacuum Utilities
The Dental Delivery System features the assistant’s instrument holder on a pull-out
arm mounted to the post. The instrument holder accommodates a saliva ejector valve,
(2) HVE, valve and three way syringe.
Solids Collector
The solids collector screens particulates introduced to the system through the saliva
ejector and high vacuum ejector. The solids collector is located at the top of the utility
center in the center. The strainer screen must be cleaned and disinfected or replaced
at least once a week.
Dental Delivery System Clean Water System
Each delivery unit comes equipped with a self contained bottle
system. This is an excellent way to ensure a clean and safe
environment for your patients. By using the water bottle you
can control the quality of water that enters the lines and reduce
the risk of contamination. Each system is equipped with a
city / bottle selector switch allowing the user to choose the
source of water to the syringe and handpiece.
The water bottle uses 40 psi pressurized air to supply water to
the syringe and handpieces. The cup filler and cuspidor bowl
rinse remains on a separate line and receives its water supply
from the office plumbing.

TPC Advanced Technology
To Use the Water Bottle
•
Make sure the unit master switch is in the “OFF” position while the water bottle
is removed.
•
Fill the water bottle, then attach to the threaded pressure cap. Be careful not to
overtighten the bottle.
•
Turn the unit back on again and check for any leaks in the bottle connection.
If any air or water leaks occur, turn the unit off and allow it to depressurize
before retightening the bottle.
•
When changing or refilling the bottle, remember to turn off the system and allow
several seconds for the unit to depressurize.
WARNING
Do not use any bottle other than the pressurized bottle provided.
Never use standard soft drink bottles, which may fail under pressure.
Do not attempt to adjust the water pressure, which is pre-set at the factory.
Pressurizing the bottle over 40 psi may cause it to rupture.
Other Uses:
The water bottle is also an effective tool in reducing the growth of biofilm and
maintaining waterline asepsis. It may be filled with waterline treatment products as
well as air to purge remaining water.

General Operation Adjustments
ALERT
Always be aware of the following items when making handpiece adjustments:
Never operate any handpiece without a bur in the chuck. When there is no bur
in place, parts of the chuck are loose, causing the turbine to be out of balance,
potentially damaging the handpiece. Also, avoid running the handpiece at full
speed or for more than a few seconds at a time when not actually cutting teeth.
Handpiece Air Coolant Adjustment
The air coolant flow control will affect all of the handpiece positions in unison. Since
the air coolant characteristics of most handpieces are similar, one setting is normally
acceptable for all of your handpieces.
Note that some handpieces draw their air coolant from the drive air. These include
any handpiece that uses a 2-hole handpiece tubing, as well as some that have a coaxial
connector. These handpieces will not be affected by the air coolant adjustment.
1.
On the foot control, flip the wet/ dry toggle OFF. Install a bur in the handpiece
that you are going to run while making this adjustment.
2.
Step on the foot control to run the handpiece at half speed. While the handpiece
is running, turn the air coolant flow control to achieve the desired flow.
Handpiece Water Coolant Adjustment
The water coolant characteristics vary significantly from one handpiece to another, so
individual flow controls are provided.
1.
After adjusting the air coolant as described above, flip the wet/ dry toggle on the
foot control to ON. Install a bur in the handpiece for which you are making this
adjustment.
2.
Turn the water coolant flow control knob clockwise to its stop. Step on the foot
control to run the handpiece at medium speed. Gradually open the flow control
(counter- clockwise) until a fine mist appears around the bur.
3.
This setting achieves optimum cooling, while minimizing the creation of
potentially hazardous aerosols.

Drive Air Pressure Adjustment
Maximum handpiece speed is controlled by adjusting the drive air pressure. The
adjusting screws and pressure gauge are located inside the control head. There is a
separate adjusting screw for each handpiece.
1.
Lift the unit head cover from the front. Pull unit cover up until internal component
are exposed.
2.
Identify the drive air gauge and the drive air adjusting screws on the control
block.
3.
Install a bur in the handpiece you are going to adjust. The adjusting screws
should correspond in sequence with the positions of the handpieces on the hanger
bar. Use a small straight slot screwdriver to make the adjustment.
4.
Run the handpiece, while turning the adjusting screw (clockwise to decrease
pressure, counter-clockwise to increase) to achieve the manufacturer’s
recommended maximum pressure with the foot control fully depressed.
IMPORTANT
The drive air gauge in the control head reads pressure at the control block.
Because of the normal restrictions in tubings and connectors, the pressure
delivered to the handpiece will be approximately 15 psi less than shown on this
gauge. Take this into account when using the built-in gauge.
Syringe Flow Adjustment
Adjusting screws allow you to control the flow of air and water from the syringe to
prevent splashing and to achieve a desirable mist pattern.
1.
Use a 3/32 inch hex key to make the syringe flow adjustment. Identify which
adjusting screw is for air and which is for water by the color of the tubing connected
to the block. Blue is water, yellow is air.
Flex Arm Balance Adjustment
The flex arm balance should be adjusted to accommodate the amount of weight that
you normally have on the handpiece control, so that the control head does not drift
up or down when the arm brake toggle is released.
1.
Remove end Arm Caps from each end of the straight horizontal flex arm. Locate
the spring adjusting nut.

•
Insert a straight slot screw driver or automotive brake adjusting tool into the hole
to engage the notches on the adjusting nut. Use a prying motion against the
sides of the slot to turn the nut and adjust the spring tension.
•
Turn the nut clockwise to increase the spring tension and load-carrying capacity
of the arm. Counter-clockwise will decrease the spring tension.
•
Release the arm brake to test the setting, and make further adjustments as needed
to achieve the desired balance.
•
Re-install the plastic end caps when the adjustment is complete.

Delivery Unit Care
Infection control in the dental office continues to be a high priority for our customers
and end users. OSHA, the ADA and the CDC are also involved in this complex issue.
Barrier Technique
The Manufacturer strongly advocates that the barrier technique be used whenever
possible to preserve the finish and appearance of the equipment. Wherever possible,
disposable barriers should be used and changed between patients. The barrier technique
will ensure maximum long term durability of the surfaces and finishes of the equipment.
Chemical Disinfection
Regardless of the chemical disinfectant used, it is imperative that the equipment be
thoroughly washed with mild soap and warm water at least once per day. This wash
down will minimize the harmful effects of chemical disinfectant residues being allowed
to accumulate on the equipment.
When using chemical disinfectants, always pay strict attention to the manufacturer's
disinfectant directions. When using concentrated disinfectants, measure the concentrate
carefully and mix according to package directions. Disinfectants solutions that are
relatively harmless to surfaces at their recommended strengths can be corrosive at
higher that recommended dilution ratios.
Control Head and Flex Arm
The control head, arm and post mounted utility housing can be cleaned with a solution
of mild detergent and warm water. A variety of surface disinfectants are available for
use in dental treatment rooms. Some of these can cause discoloration of painted,
plated or anodized surfaces with repeated use. This can be minimized by careful
adherence to the disinfectant manufacturer's instructions and by frequent washing
with soap and water.
Waterline Asepsis
At the end of every day, the lines should be purged with air to reduce the growth of
biofilm. The Dental Delivery System control unit is equipped with a handpiece flush
system that allows you to periodically flush fresh water through the handpiece tubings.
The need for this is that the low flow of water through the tubings during normal use
can lead to stagnation and the potential growth of biofilm contamination.

The weekly cleaning procedure should be performed at least once a week, preferably
at the start of the week before treating patients. If the unit is to be stored for any
length of time, perform the weekly maintenance routine immediately before and after
storage.
1.
Purge the unit with air.
2.
Flush the system with disinfectant solution
3.
Allow the disinfectant to remain in the unit for 10 to 20 minutes, then flush the
system again until all the solution is used up.
4.
Purge the unit with air.
5.
Fill the unit with clean water.
Disinfecting and Sterilization
The use of chemical disinfecting agents is not necessary if the instrument is going to
be sterilized. While their use may be easy and quick, it is important to know the
effectiveness of any chemical disinfectant against the various agents of infection that
may be encountered.
Table 1
Unacceptable Disinfectants
These disinfectants will harm the surface finishes of
dental equipment and are not recommended. Use of
these products will void your warranty.

*The Manufacturer makes no representation as to the disinfectant efficacy of these products. We make no warranty expressed or
implied that these disinfectants will not damage the surface finishes. Damage and discoloration of the surface finishes are not
covered under the warranty.
**Iodophor-based disinfectants will cause yellow staining on many surfaces. Regular washing with soap and water will minimize
this staining. Iodophor neutralizers such as Promedyne are also available.
Page 12
TPC Advanced Technology
While none of the products listed in Table 1 will adversely affect the performance of
your instruments, most chemical disinfectants can be expected to cause some degree
of discoloration. This can be minimized by frequent cleaning with soap and water,
and in the case of Iodophors, regular use of Iodophor Neutralizers.
Sterilization
Any of the following sterilization methods may be safely used on your vacuum
instruments:
•
Steam Autoclave
•
Ethylene Oxide Gas
•
Chemical Vapor Process
Do not allow the instruments to come into contact with the walls of the sterilizer.
Avoid placing the instruments in close proximity to the sterilizer heating element.
Dry heating sterilization is not recommended because of the difficulty in maintaining
the precise temperature control necessary to prevent damage to the instruments.
Do not microwave vacuum instruments or syringes as this may cause internal damage
to your microwave oven.

Assistant’s Package Care
Cuspidor
Daily care of the cuspidor bowl and components should be a regular part of the
equipment cleaning schedule.
After Each Patient
Rinse the cuspidor bowl thoroughly by pouring a few cups of water down the drain.
This will flush out the drain lines and prevent material from accumulating.
Vacuum Utilities
Daily care of the vacuum utilities and components should be a regular part of the
equipment cleaning schedule.
After Each Patient
Draw clear water through each valve while opening and closing it several times. Leave
the valve open for several seconds to allow all of the water to clear the hoses. The
HVE and SE tips should always be replaced with sterile ones before each patient.
At the End of Each Day
It is recommended that a vacuum system sanitizing solution be drawn through each
valve while opening and closing it.
Cleaning the Solids Collector
At least once a day, the solids collector screen should be removed for cleaning. Turn
off the vacuum pump. Remove the solids collector cap and lift out the screen. If there
is an excessive amount of material in the screen, more frequent cleaning is necessary.
Cleaning
Clean the external surfaces of the vacuum instruments using a solution of mild detergent
and warm water. Thoroughly rinse the syringe with clear water, then dry with a soft,
lint-free cloth.
Ultrasonic cleaning is not recommended, as the chemicals used may damage the surface
finishes of the instrument.
Page 14
TPC Advanced Technology
Sterilization
Remove each valve from its tubing for sterilization. A vacuum plug may be inserted
into the quick disconnect while there is no valve in place. In any situation involving
high risk patients, it is recommended that the instruments be removed for sterilization
after every patient.
As Needed
Disassemble the valve and lubricate the internal parts when operation becomes stiff or
sticky. Clean the inner surfaces and apply a small amount of O-ring lubricant to the
moving parts and O-rings.
