Intended use
Careclave is intended for use in the medical field, especially in dentistry. This device is not intended to be used in a pa-
tient environment. In accordance with }EN13060 this device is a steam sterilizer (autoclave) with type B cycles. As a
universal steam sterilizer, it is suited to highly-demanding sterilization tasks. It can be used to sterilize, e.g., narrow lu-
men instruments – both wrapped or unwrapped – and textiles.
In addition, Careclave can be used to reprocess compatible connectible dental instruments (e.g. transmission instru-
ments) in a container (Carebox) provided for this purpose. The internal and external cleaning as well as the subsequent
thermal disinfection comply with the specifications of }ENISO15883-1 and -2. Optionally, sterilization with type S cycles
can be carried out instead of thermal disinfection, or automatic care can be carried out with care oil.
WARNING
Any attempt to sterilize liquids can result in a }delay in boiling. This can result in burns and damage to
the device.
nNever use this device to sterilize fluids. It is not licensed for the sterilization of fluids.
User benefits
Dan
With the help of Careclave, you can fully comply with the reprocessing recommendations of the German Commission for
Hospital Hygiene and Infection Prevention at the }RKI, as well as the normative requirements from }EN13060
and }ENISO15883-1 and -2.
Reprocessing of semi-critically classified dental transmission instruments
The simultaneous reprocessing of a maximum of eight dental transmission instruments takes place exclusively in the
Carebox. For successful cleaning and disinfection, the transmission instruments must be connected to the appropriate
adapters. Cleaning and disinfection take place both in the inner area of the dental instrument (interior cleaning) and on
the outer surfaces (exterior cleaning). During subsequent care with care oil, only the drive areas of the dental transmis-
sion instruments are specifically treated. Depending on the program selected, either thermal disinfection is carried out
before care or sterilization after care.
Reprocessing of semi-critically classified connectible hollow bodies
The simultaneous reprocessing of a maximum of eight ultrasonic and air scaler tips takes place exclusively in the
Carebox. For successful cleaning and disinfection, the tips must be connected to the appropriate adapters. Cleaning and
disinfection take place both in the inner area of the tips (internal cleaning) and on the outer surfaces (external cleaning).
Depending on the program selected, either thermal disinfection or sterilization is then carried out.
Combined sterilization
In the Care-B program, reprocessing in the Carebox is possible in combination with type B sterilization. This allows you
to sterilize instruments or tips in the Carebox as well as critically classified (wrapped) and narrow instruments in the steri-
lization chamber in one program run.
Program runs for the Carebox
Cleaning & disinfection
Careclave can simultaneously clean and thermally disinfect up to eight dental transmission instruments or ultrasonic and
air scaler tips. For successful cleaning and disinfection, the instruments in the Carebox must be connected to the adapt-
ers provided.

Cleaning and disinfection takes place both in the inner area of the dental instrument (internal cleaning) and on the exter-
nal surfaces (external cleaning). Cleaning is done with demineralised water, partly with the support of compressed air
pulses and without the use of chemicals.
During the program run, the following steps (phases) are completed:
Carebox detection
Carebox detection (Carebox-Connect) determines the type of Carebox used (Blue/Green) and activates (Carebox Blue)
or deactivates (Carebox Green) the care for the program run.
Pre-cleaning
Pre-cleaning is done with cold water. The transmission instruments soiled and contaminated by proteins or coarse organ-
ic adhesions are cleaned mechanically to avoid denaturation (coagulation) due to excessively high water temperatures.
At the end of pre-cleaning, the rinse liquor is drained to remove the proteins and other contaminants from the system.
Intermediate cleaning
In intermediate cleaning, a new rinse liquor is used and further soiling is dissolved. During this process, the temperature
of the rinse liquor rises slightly. At the end of intermediate cleaning, the rinse liquor is drained again to further lower the
residual contamination.
Final cleaning
In final cleaning, the newly introduced rinse liquor is continuously heated. At a temperature of 55°C, any remaining or-
ganic deposits and soiling are dissolved from the instruments.
Disinfection (Program Care-Therm)
Immediately after final cleaning, }A0-value controlled thermal disinfection takes place at a temperature above 92°C. The
rinse liquor from the final cleaning is reused for thermal disinfection. The disinfection phase is conceived so as to reach
an A0 value of at least3000. This eliminates vegetative bacteria and fungi or fungal spores and inactivates viruses (in-
cl.HBV, HCV) and achieves the effective rangeAB according to the specifications of the }Robert Koch Institute.
The transmission instruments prepared with this method are suitable for use in treatments with the risk classification
semi-critical B.
Care (optional)
During care, the care oil is specifically dosed only into the drive areas of the transmission instruments. The dosing sys-
tem is designed so that each instrument, regardless of its type, receives a sufficient amount of the care oil.
Sterilization
Sterilization S (Program Care-S)
Instead of disinfection in the Carebox, sterilization with type S cycles (according to }EN13060) can also be carried out.
This is specially designed for the steam penetration of dental transmission instruments. Sterilization is carried out at a
temperature of 134°C and with a sterilization time of 3:30min. The transmission instruments prepared in this way are
suitable for use in treatments with the risk classification semi-critical B.
Sterilization B (Program Care-B)
Instead of sterilization exclusively in the Carebox, sterilization of the Carebox including the entire chamber can also be
carried out with type B cycles (according to }EN13060). This is additionally designed for the steam penetration of pro-
duct with narrow lumen (hollow body A), both wrapped and unwrapped. Sterilization takes place at a temperature of
134°C and with a sterilization time of 5:30min. The wrapped transmission instruments prepared in the sterilization
chamber are suitable for use in treatments with a risk classification of critical B.
Drying
Drying before the end of the program not only serves to intensively dry the inner lumen of the instruments, but also to
empty the Carebox. It is carried out both as vacuum drying and in the form of compressed air drying. Apart from conform-
ity with }EN 13060, drying also contributes to maintaining the value of your instruments. In the Care-B program, drying is
also designed for wrapped loads in the sterilization chamber.

Program runs for the sterilization chamber
A reprocessing program runs in three main phases: the air removal and heating up phase, the sterilization phase and the
drying phase. After program start, you can follow the program run on the display. It shows the chamber temperature and
pressure as well as the time until the end of drying.
Program phases of a standard sterilization program
Program phase Description
1. Air removal and heating
up phase
Air removal
The air removal phase comprises the conditioning and the fractionating phase.
During conditioning, steam is repeatedly injected into and removed from
the }sterilization chamber. This generates over-pressure and the residual air is
removed. Then, during fractionation, the mixture of air and steam is evacuated from
the sterilization chamber and steam is injected. This procedure is also called the
fractionated vacuum procedure.
Heating
The continued steam injection into the sterilization chamber leads to an increase in
pressure and temperature which continues until the program-specific sterilization
parameters have been reached.
2. Sterilization phase Sterilizing
If the pressure and temperature correspond to the program-dependent nominal
values, the sterilization phase begins. The corresponding process parameters
(pressure and temperature) are held at sterilization level.
3. Drying phase Pressure release
The sterilization phase is followed by pressure release from the sterilization
chamber.
Drying
The sterile material is dried using a vacuum (vacuum drying).
Ventilation
Upon program end, the sterilization chamber is filled with sterile air via the sterile
filter and adjusted to the ambient pressure.
Program phases of the vacuum test
Program phase Description
1. Evacuation phase The sterilization chamber is evacuated until the pressure for the vacuum test has
been reached.
2. Equilibration time An equilibration time of five minutes will follow.
3. Measurement time The measurement time amounts to ten minutes. The pressure increase within the
sterilization chamber is measured during the measurement time. The evacuation
pressure and the equilibration time or measurement time are shown on the display.
4. Ventilation The chamber is ventilated after the end of the measuring time.
5. Test end The display shows the test result, the batch number, the total number of batches
and the leakage rate.
Care procedure
Careclave offers the possibility of caring for transmission instruments with the help of an integrated function for distribut-
ing and dosing care oil. Furthermore, chuck care can be done manually with the ADDcare integrated care station.
The Carebox Blue is used for the reprocessing of instruments that must be maintained with maintenance oil.
The amount of care oil applied to the transmission instruments is sufficient for the next treatment. In addition, observe the
instructions of the instrument manufacturer to prevent damage to the transmission.

Sterilization procedure
The steam sterilizer sterilizes on the basis of the }fractionated vacuum procedure. This guarantees the complete and ef-
fective wetting/penetration of the load with saturated steam.
The steam sterilizer uses the double jacket technology to generate the sterilization steam, i.e. the steam sterilizer is fitted
with a separate steam generator combined with a double-walled sterilization chamber. After heating, steam is held con-
stantly available in the double jacket. This gives the walls of the sterilization chamber a defined temperature and protects
the sterilization chamber from overheating. This especially effective procedure supports the quick }evacuation of the air
from the sterilization chamber, the sterilization packaging and instrument cavities. This permits the sterilization of large
quantities of instruments or textiles directly one after each other, thereby achieving excellent drying results.
Type of the feed water supply
The steam sterilizer works with a one-way }feed water system. This means that it uses fresh feed water (demineralized
or distilled water) for every sterilization procedure. The quality of the feed water is subject to permanent monitoring via
integrated }conductivity measurement. If combined with careful preparation of the instruments, this serves largely to pre-
vent stain accretion on the instruments and soiling of the steam sterilizer.
Safety equipment
Internal process monitoring
A }process evaluation system is integrated in the electronics of the steam sterilizer. It compares the process parameters
(such as temperature, time and pressure) during a program run. It monitors the parameters in terms of their threshold
values during control and regulation and guarantees safe and successful sterilization. A monitoring system checks the
device components of the steam sterilizer for their functionality and their plausible interaction. If one or more parameters
exceeds pre-determined threshold values, the steam sterilizer issues warnings or malfunction messages and if neces-
sary, aborts the program. In the case of a program abort, follow the instructions on the display.
The steam sterilizer uses an electronic parameter control. This enables the steam sterilizer to optimise the total operating
time of a program in dependence on the load.
Internal logic monitoring
The electronics of the steam sterilizer monitor the successful program run by means of two separate test processes.
When a program has been successfully completed, it is shown on the display as a successful program. In addition, the
status LED below the display illuminates green.
Door mechanism
Careclave constantly checks pressure and temperature in the sterilization chamber and prevents the door from being
opened when over-pressure has built up in the sterilization chamber. The motor-driven automatic door locking mecha-
nism opens the door slowly by turning the locking spindle. This also holds the door whilst it opens. Pressure equalisation
will have been performed by the time that the door is completely open, even following pressure differences.
Automatic monitoring of the feed water
The quantity and quality of the }feed water is automatically checked before every program start.
