Technical Description
Intended Use - Dental Unit
The dental delivery system is a combination of dental equipment components used to carry,
position and control the devices used in the practice of dentistry. Delivery systems provide for handpieces and
deliver air, water, vacuum and low voltage electricity to the dental patient. Delivery systems generally have several
components including a control head, cuspidor bowl, vacuum utilities, assistant’s utilities, a multifunction syringe
and a junction box. Delivery systems can be mounted to the wall, the dental chair or on a mobile cart.
Air, water, vacuum, drain and electrical power generally enter the system through the junction box. Shutoff valves, pressure regulators, transformers and other devices are located in the junction box or the post
mounted utility box. Tubing delivers air, water and vacuum to the control head and to the dental handpieces and
multifunctional syringe. Low voltage electricity may be delivered to the control head for operating items such as
scalers, electric handpieces and fiber optic light sources.
The control head contains adjustment knobs for controlling handpiece pressure, and the amount of coolant air and
water. The dentist controls the rate and flow through the pressure applied to the foot control or syringe buttons.
There may be a low voltage control device to control chair positioning and turn the inter-oral light on and off.
Handpiece Compatibility
This system is designed to be compatible with air driven handpieces that conform to ISO 13294
and electric handpieces that conform to ISO 11498.
For the air driven handpieces, tubing is available in standard 4 or 6 hole Midwest style with or without light source.
For electric handpieces, dental units will be equipped with an “E-type” coupler and cord set.
Other tubings may be available upon request.
The end user will have specified the preferred type prior to ordering from the factory. It is the responsibility if
the end user to procure appropriate handpieces for use with this delivery system. Certain countries may have
particular regulations regarding which handpieces are acceptable for use; e.g. countries in the European Union
require handpieces which meet the requirements of the Medical Devices Directive 93/42/EEC. See your local dealer
for additional information.
Device Classification
The dental delivery system is classified as Class 1 device under rule FDA CFR 21, Class II device
under Health Canada guidelines, and a Class IIa device under rule 11 of the MDD 93/42/EEC of
0473
Annex IX. Accordingly, the provisions of Annex II apply if the e-motor option is chosen.

CLEANING, DISINFECTING & STERILIZATION
Cleaning Equipment 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.
IMPORTANT: Do not use powdered cleansers, scouring pads or abrasive scrubbers on any of the
painted, plastic or metal surfaces of this dental unit. To remove dried-on material, use a soft-bristled
brush and a solution of mild detergent.
Disinfection & Sterilization
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.
The Manufacturer will not attempt to specify the required
intervals for disinfection nor can it recommend the overall
best surface disinfectant. Please refer to the Infection
Control Recommendations published by the American
Dental Association for further information. The question
is often asked, “What should I use to disinfect my dental
unit, chair and light?” This question is more complex than
it seems because of the wide variety of products on the
market as well as formulations of the products changing to
meet the needs of increased asepsis.
Barrier Technique
The Manufacturer strongly advocates 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 be-
Unacceptable Disinfectants
These disinfectants will harm the surface finishes of
dental equipment and are not recommended. Use of
these products will void your warranty.

tween 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.
Disinfectant solutions that are relatively harmless
to surfaces at their recommended strengths can be
corrosive at higher than recommended dilution ratios.
Conditionally Acceptable Disinfectants*
These disinfectants have been found to be the least
harmful to the equipment surfaces by our test methods.
Chemical Composition
Phthalaldehyde
Quaternary Ammonium
Glutaraldehyde
**Iodophor-based disinfectants will cause yellow staining on many surfaces.
CAUTION: Only disinfect by wiping, no spray
disinfection. Please be aware that Marus
expressly rejects any claims for warranty
or damages when using other cleaning
and disinfections solutions.

CAUTION: *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.
MAINTENANCE
Care of the Unit
Asepsis Automatic Control
Control Head and Arm
The control head and post 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.
NOTE: Some models may not come equipped with the
handpiece control head. Refer to the sections of this
manual that only pertains to your particular unit.
IMPORTANT: Do not use powdered cleansers, scouring
pads or abrasive scrubbers on any of the painted, plastic
or metal surfaces of this dental unit. To remove dried-on
material, use a soft-bristled brush and a solution of mild
detergent.
Handpiece Flush — Daily Maintenance
The control system is equipped with a handpiece flush
system that allows you to periodically flush fresh water
through the handpiece tubings. The need for this is caused
by the low flow of water through the tubings during normal
use, which can lead to stagnation and the potential growth
of “biofilm” contamination.
We recommend that you flush the tubings at the beginning
and end of each day. This may be done with or without
handpieces installed, but having handpieces on the
tubings will restrict flow, so a longer flush time will be
required.
WARNING: In order to mitigate the risk
of cross-contamination between patients,
disinfection and sterilization of handpieces
must occur after each dental procedure.
Refer to the handpiece manufacturer’s
instructions and recommendations for
sterilization or disinfection procedure.
All of the tubings are flushed simultaneously. Hold them together and direct them into a basin, sink or cuspidor to catch
the water. Flip and hold the flush toggle.
Allow adequate time for fresh water to make its way through the entire system and displace all standing water. The
American Dental Association and the Centers for Disease Control can provide additional recommendations regarding this
procedure, including information on frequency and duration of flushing and the use of antibacterial solutions in the selfcontained water system.
Weekly Maintenance
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:
a. Turn the unit off. Empty the water bottle, replacing
the water with cleaning solution (see Disinfectant
Solution, next page).
b. Hold the handpiece tubings and syringe over the
cuspidor or other suitable container. Turn the unit on, wait a few moments, then operate the flush toggle, syringe and foot control until a continuous stream of solution is running through the system.
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:
a. Hold the handpiece tubings and syringe over a container. Turn the unit on, wait a few moments, then operate the flush toggle, syringe and foot control until all solution is purged from the system.
b. Turn the unit off. (If the unit will be stored, stop here.)
5. Fill with clean water:
a. With the unit turned off, remove the empty disinfectant bottle. Replace with clean bottle and water.
b. Hold the handpiece tubings over a suitable container. Turn the unit on, wait a few moments, then operate the flush toggle until a continuous stream of water is flowing through the system. Replace handpieces and do the same with the syringe. The unit is now ready for use.
Handpiece Oil Collector:
Replace the 2 x 2 gauzes with clean gauzes in the
handpiece oil collector every 90 days or more often if
handpieces are oiled frequently.
7
CLEAN WATER SYSTEM
Maintenance
The water bottle system is designed to optimize the quality
of water being delivered to the handpieces and syringe.
The Clean Water System has three functions:
1) The system may be filled with filtered or sterile water for patient use.
2) The system may be filled with disinfectant for flushing
the syringe and handpiece tubings.
3) The unit can be purged with air to inhibit the growth of biofilm.
CAUTION: Disinfect new water bottle
prior to use.
NOTE: When filling water bottle, leave an air gap at
the top of bottle to allow bottle to depressurize when
removing it from unit.
In order to maintain a truly asepsis water system, daily and weekly cleaning procedures must be performed in a
consistent, regular manner. Failure to do so could result in contaminated water lines and a lower water quality than what
is acceptable for patient use. Follow the daily and weekly maintenance instructions on page 7 when performing proper
cleaning of the tubings with the clean water system.
Once a month activate the City/Bottle Water Switch ensuring that the switch functions properly. If any issues are found,
call authorized service representative to replace the toggle valve.
Once a month activate the Foot Control toggle valve ensuring that the toggle valve functions properly turning the water
on and off to the handpiece. If any issues are found, call authorized service representative to replace the toggle valve.
Disinfecting the bottle:
Fill bottle with the 100 ml disinfectant
solution, shake vigorously and let it
settle for 10 minutes. Shake again, then
rinse twice with water.
The Disinfectant Solution:
We recommend 100 ml of
disinfectant solution for
each application per week.
Always use a fresh mixture
every week.

Once a month visually check handpiece holders for excessive wear and handpiece activation. If any issues are found,
then call authorized service representative to replace.
Once a month visually check handpiece tubing for wear and tear and any separation of the tubing from the connector. If
not then call authorized service representative to replace.
Once a month verify that the electro-torque motor handpiece water flow is functioning properly. If not then call authorized
service representative to replace gauze in oil collector.

Care of Vacuum Utilities
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 Saliva Ejector 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 and checked. Turn off the
vacuum pump. Remove the solids collector cap
and lift out the disposable screen. Replace if
neccessary with a new screen, (Part # 46R143).
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.
Solids Collector Assembly
Ultrasonic cleaning is not recommended, as the
chemicals used may damage the surface finishes
of the instrument.
CAUTION: Do not use sodium hypochlorite
or any chlorine bleach on the vacuum
instruments. These products will permanently
damage the instruments. Never use powdered
cleansers, scouring pads or abrasive
scrubbers, any of which can damage the
finishes.
Sterilization
Remove each valve from its tubing for sterilization.
A vacuum plug may be inserted into the quickdisconnect 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.
Care and Maintenance

Cuspidor Care and Cleaning
Daily care of the cuspidor bowl and
components should be a regular part
of the equipment cleaning schedule.
Consequently, your cuspidor has been
designed with simple removal and cleaning
in mind. Following these simple steps will
ensure the long life and quality condition of
your equipment.
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.
At the End of Each Day
•
Flush the drain with a sanitizing solution.
See the section on Waterline Asepsis for
more information.
•
The cup filler and bowl rinse spouts are
autoclavable and may be removed by
pulling upward. The O‑rings may be
left on the spouts for autoclaving, but it
would be helpful to add a small amount
of O‑ring lubricant before reinstalling.
•
The drain screen may be removed by
simply lifting it out of the bowl. It may
be cleaned with a sanitizing solution or
replaced when necessary. See your
dealer for replacement screens.
•
10
The cuspidor bowl may be snapped
loose from the drain assembly and
removed. Unseat the bowl from the
three rubber grommets beneath it and

Quick Switch Water System
The quick switch water bottle system 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.
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. A toggle switch allows the user
to choose whether to use the office plumbing or the
water bottle (see illustration).

1. Make sure the unit master switch is in the
‘OFF’ position while the water bottle is
removed.
2. Fill the water bottle with distilled, reverse
osmosis or deionized water, then attach the
bottle adapter to the water bottle.
3. Align the grooves in the bottle adapter to the
guide pins on the manifold. Push upwards
while turning to follow the path of the grooves
in the bottle adapter.
4. The water bottle will “click” into place when
fully seated.
5. 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.
CAUTION: Use only water bottles
supplied by the manufacturer. Do
not use soft drink bottles which are
thin-walled and may rupture under
pressure.

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.
The 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.
Note: When not present on the foot control body,
this toggle switch can be found on the control
head.
The optional Chip Blower Button on the foot
control provides a convenient means of blowing
loose debris from the prep area without moving
hands or changing instruments.
