Description of Unit
ProCart II™ is an easy-to-clean, self-contained operatory system that sets up in just a few minutes. It
requires no plumbing and is mobile for ease of movement between operatories or for storage.
Air System
The internal air compressor will activate when main power switch is turned on, filling the air tank and
pressurizing the water reservoir. The compressor will deactivate when air pressure reaches 100psi and
will recycle at 70psi.
Water System
Water container should be filled 3/4 full. Water to handpieces is controlled by the foot control toggle
and the valves on the front of the unit. The water for the air/water syringe is controlled by depressing
the water button on the syringe. Syringe water pressure is controlled by the water regulator at a
maximum of 40psi.
Vacuum System
The internal vacuum system is activated by removing HVE or saliva ejector from holder. You may use
either the saliva ejector or HVE as needed. There is a vacuum solids trap and a waste purge pump. In the
vacuum container is an automatic shut down system to prevent spillage. Cannot used Saliva Ejector and
HVE at the same time.
Electrical System
There are two electrical outlets on your system, one internal outlet and one external, to accommodate
accessories. You may use a maximum of 2 amps on the internal and external outlets. The unit is
protected by a 15 amp circuit breaker.

Dental Office Infection Control Guidelines (CDC)
DENTAL OFFICE INFECTION CONTROL GUIDELINES FOR THE PROTECTION OF
PATIENTS AND DENTAL CARE PERSONNEL AS RECOMMENDED BY THE UNITED
STATES CENTERS FOR DISEASE CONTROL (CDC)
NOTE: A medical history should be taken at the initial patient visit and on recall, updated
with notations made on the chart.
Barrier Techniques
1) Dentists, hygienists and assistants should wear new gloves for each patient treated. Hands
should always be washed with liquid soap before and after treatment, contact with patients or after
touching inanimate objects likely contaminated by blood or saliva, and before leaving the operatory.
Remove torn, cut or punctured gloves immediately, wash hands, and re-glove before completion of
dental procedures.
2) During all treatment procedures, dentists, hygienists and assistants should wear face masks
and protective eyewear, or in lieu of both of these, a chin-length plastic face shield.
The outside outlet is used for external accessories use.
Never use more than 2 amps between the inside and outside outlets.
The air 1/4”QD is used for accessories that require air. The
pressure will be between 70 to 100psi. The accessory should not
be used at the same time you are using one of the handpieces.
You may connect to an external air or nitrogen system. Make sure
the pressure does not exceed 100psi.
The water 1/4” QD is used for accessories that require water. The
pressure will be 65psi.
You may connect to an external water system. Make sure the
pressure does not exceed 65psi. You will need to disconnect the
water bottle from the unit.

15
3) Reusable and/or disposable gowns, laboratory coats or uniforms should be worn when
street clothing may be soiled with blood or other body fluids. Gowns should be changed at least
daily or when visibly soiled with blood.
Cleaning and Disinfection of Dental Unit and Environmental Surfaces
1) After treatment of each patient and at the completion of daily work activities, countertops
and dental unit surfaces that may have become contaminated with patient material should be cleaned
with disposable toweling, using an appropriate cleaning agent and water as necessary. Surfaces then
should be disinfected with a suitable chemical germicide.
2) A chemical germicide registered with the EPA as a “hospital disinfectant” and labeled for
“tuberculocidal” (i.e., mycobactericidal) activity is recommended for disinfecting surfaces that have
been soiled with patient material. These intermediate level disinfectants include phenolics,
iodophors, and chlorine-containing compounds. Because mycobacteria are among the most
resistant groups of microorganisms, germicides effective against mycobacteria should be effective
against many other bacterial and viral pathogens. A fresh solution of sodium hypochlorite
(household bleach) prepared daily is an inexpensive and effective intermediate-level germicide.
Concentrations ranging from 500 to 800 ppm of chlorine (a 1:100 dilution of bleach and tap water
or 1/4 cup of bleach to 1 gallon water) are effective on environmental surfaces that have been
cleaned of visible contamination. Caution should be exercised, since chlorine solutions are corrosive
to metals, especially aluminum.
3) Low-level disinfectants - EPA registered “hospital disinfectants” that are not labeled for
“tuberculocidal” activity (e.g., quatemary ammonium compounds) - are appropriate for general
housekeeping purposes such as cleaning floors, walls and other housekeeping surfaces. Intermediate
and low level disinfectants are not recommended for reprocessing critical or semi-critical dental
instruments.
4) Before high-level disinfection or sterilization, and while wearing heavy duty rubber
(household) gloves, ultrasonically clean (preferably) or scrub instruments in order to remove debris.
Use and Care of Handpieces and Other Intra-oral Dental Devices
1) Routine between-patient use of a heating process capable of sterilization (i.e., steam under
pressure (autoclaving), dry heat, or heat/chemical vapor) is recommended for all highspeed dental
handpieces, lowspeed handpiece components used intra-orally, and reusable prophylaxis angles.
Manufacturers’ instructions for cleaning, lubrication, and sterilization procedures should be followed
closely to ensure both the effectiveness of the sterilization process and the longevity of these
instruments. According to manufacturers, virtually all highspeed and lowspeed handpieces in
production today are heat tolerant and most heat-sensitive models manufactured earlier can be
retrofitted with heat-stable components.
2) Internal surfaces of highspeed handpieces, lowspeed handpiece components, and
prophylaxis angles may become contaminated with patient material during use. This retained patient
material then may be expelled intra-orally during subsequent uses. Restricted physical access -
particularly to internal surfaces of these instruments - limits cleaning and disinfection or sterilization
with liquid chemical germicides. Surface disinfection by wiping or soaking in liquid chemical
germicides is not an acceptable method for reprocessing highspeed handpieces, lowspeed handpiece
components used intra-orally, or reusable prophylaxis angles.

16
3) Highspeed handpieces should be run to discharge water and air for a minimum or 20-30
seconds after use on each patient. Handpieces, in addition, should be heat sterilized between uses
on patients. This procedure is intended to aid in physically flushing out patient material that may
have entered the turbine and air or water lines. Use of an enclosed container or high-velocity
evacuation should be considered to minimize the spread of spray, splatter, and aerosols generated
during discharge procedures. Additionally, there is evidence that overnight or weekend microbial
accumulation in water lines can be reduced substantially by removing the handpiece and allowing
water lines to run and to discharge water for several minutes at the beginning of each clinic day.
Sterile saline or sterile water should be used as a coolant/irrigation when surgical procedures
involving the cutting of bone are performed.
Other Important Issues
1) A “no-touch” technique (e.g., hemostats or needle holders), should be utilized when using
“sharps” (needles, scalpels, blades, etc.).
2) In the operatory, sterilized and decontaminated instruments, charts, and other objects should
be protected from patient contact.
3) “Sharps” should be disposed of in puncture proof containers; hazardous and/or infectious
waste materials, which include “sharps,” should be disposed of in a manner consistent with
prevailing local laws.
4) All dental personnel should be encouraged to receive immunization protection whenever
possible, e.g., hepatitis B immunization.
5) All impressions, models and devises should be disinfected before submission and upon
receipt from the dental laboratory.
