ESD protective measures ESD stands for ElectroStatic Discharge.
ATTENTION!
Connector pins or sockets bearing ESD warning labels
must not be touched or interconnected without ESD
protective measures.
Humidity: 30% - 60%
Ambient temperature: 16°C - 26°C
60°F - 80°F
Sirona Dental Systems GmbH
Operating Instructions DAC PROFESSIONAL
61 33 826 D 3554
D 3554.201.01.04.02 9
ESD protective measures include:
• Procedures for preventing electrostatic charge
build-up (e.g. air conditioning, air moistening,
conductive floor coverings and non-synthetic
clothing)
• Discharging the electrostatic charges of your own
body on the frame of the UNIT, the protective ground
wire or large metallic objects
• Connecting yourself to ground using a wrist band.
We therefore recommend that all persons working with
this system be instructed on the significance of this
warning label. Furthermore, they also should receive
training in the physics of electrostatic discharges which
can occur in the practice and the destruction of
electronic components which may result if such
components are touched by electrostatically charged
USERS.
ESD stands for ElectroStatic Discharge. Electrostatic
discharge must be preceded by electrostatic charging.
Static electric charges generally build up whenever two
bodies are rubbed against each other, e.g. when walking
(shoe soles against the floor) or driving a vehicle (tires
against the street pavement). The amount of charge
depends on several factors:
Thus the charge is higher in an environment with low air
humidity than in one with high air humidity; it is also
higher with synthetic materials than with natural
materials (clothing, floor coverings).
The following rule of thumb can be applied to assess the
transient voltages resulting from an electrostatic
discharge.
An electrostatic discharge is:
• perceptible at 3,000 V or higher
• audible at 5,000 V or higher (cracking, crackling)
• visible at 10,000 V or higher (arc-over)
The transient currents resulting from these discharges
have a magnitude of 10 amperes. They are not
hazardous for humans because they last for only several
nanoseconds.
Voltage differentials exceeding 30,000 volts per
centimeter may lead to a charge transfer (electrostatic
discharge, lightning, arc-over).
Integrated circuits (logical circuits and microprocessors)
are used in order to implement a wide variety of
functions in dental/X-ray/CEREC systems. The circuits
must be miniaturized to a very high degree in order to
include as many functions as possible on these chips.
This leads to structure thicknesses as low as a few ten
thousandths of a millimeter.

10 D 3554.201.01.04.02
It is obvious that integrated circuits which are connected
to plugs leading outside of the unit via cables are
sensitive to electrostatic discharge. Even voltages which
are imperceptible to the user can cause breakdown of
the structures, thus leading to a discharge current which
melts the chip in the affected areas. Damage to
individual integrated circuits may cause malfunction or
failure of the system.
To prevent this from happening, the ESD warning label
next to the plug warns of this hazard.
Safety information Be careful when opening the door of the autoclave,
especially if you are interrupting a drying cycle.
Small amounts of residual steam can escape
through the door and burn operating personnel.
After opening the autoclave door, do not touch
exposed hot metal parts. – burning hazard! Be
sure to use the tray handle when removing still-hot
trays from the autoclave. Be sure to use a suitable
hand protection (e.g. potholders or gloves) when
removing other sterilizing containers.
It is recommended to install a leak detector in the
water inlet (see installation instructions, chapter 7).
We also recommend using the
SIRODEM water treatment system from Sirona.
This unit is not suitable for the sterilization of
liquids.
According to the currently valid VDE regulations,
this device is not suitable for operation in areas
subject to explosion hazards.
Empty the water supply tank before transporting
the autoclave. If the autoclave has water inside, do
not tilt it.
This device may be repaired only by an authorized
dealer or service department. The persons
performing such repairs must use original spare
parts and observe the relevant servicing
instructions.
Disconnect the power plug before opening the
housing!
This autoclave will properly sterilize only if the
operating personnel observe these Operating
Instructions, and especially, follow the instructions
regarding program-specific loading of the autoclave.
The autoclave is designed for use outside of the
patient’s immediate vicinity (radius of 1.5 meters
around the treatment center).

6 Performance features of unit
6.1 Fractioned pre-vacuum procedure
Fractioned pre-vacuum repeatedly evacuates the air
from the autoclave and alternately introduces steam
between evacuations, thus providing the required
penetration of the sterilized objects with saturated
steam.
This ensures fast and effective execution of difficult
sterilization tasks: e.g. instruments with narrow bores
and large amounts of textiles.
Steam penetration can be confirmed via the Bowie &
Dick test (a recognized procedure used in large-scale
sterilization). A special test program has been
implemented for this purpose.
6.2 Sterilization categories
DAC PROFESSIONAL features 5 sterilization programs
for temperatures of 134°C: the "Universal program" for
wrapped objects, the "Fast program B", the "Prion
program" (a special Universal program) and the "Quick
program S" for unwrapped items. The “Gentle program”
is a program for sterilizing textiles and rubber articles at
121°C. The user can at any time perform additional
functional checks of the autoclave by running the Bowie
& Dick test for steam penetration and the Vacuum test
for leak testing.
6.3 Separate steam generation
The powerful steam generator outside the actual
sterilization chamber makes it possible to sterilize large
loads of instruments or textiles in a short time. No waiting
periods are necessary between sterilization cycles, and
excess temperatures cannot occur within the
sterilization chamber.
6.4 One-way system / conductivity measurement / water supply
DAC PROFESSIONAL operates with the tried and
proven one-way system: this means that all evaporated
water and all impurities contained in this water are
removed from the autoclave upon pressure release.
Clean feed water is therefore used for the following
program cycle.
An integrated conductivity measurement system
monitors the quality of the feed water used in steam
generation. We recommend using a water supply with
feed water.
Sirona Dental Systems GmbH
Operating Instructions DAC PROFESSIONAL
61 33 826 D 3554
18 D 3554.201.01.04.02
If the instruments are carefully prepared, this
arrangement prevents spots on the items sterilized and
avoids fouling of the autoclave.
6.5 Electronic parameter control
The microprocessor installed in the
DAC PROFESSIONAL implements an electronic
parameter control system which continuously monitors
pressure, temperature and time in the programs. The
total operating times can thus be optimized according to
the load and the temperature of the autoclave.
The process evaluation and monitoring system
contained in the program control system compares
momentary process parameters with standard
processing data and monitors the process with respect
to limit temperatures, limit times and limit pressures.
This function detects malfunctions in the program cycle
and guarantees the security of the sterilization result.
6.6 Vacuum drying
The vacuum drying feature ensures good drying results,
even for wrapped items.
6.7 Preheating
Activating the preheating function warms up the cold
autoclave chamber before sterilization or maintains the
temperature between sterilization cycles. This shortens
the duration of cycles and considerably reduces the
formation of condensation, thus optimizing drying
results.
6.8 Documentation of batch results
Batch results can be documented via the following
output media:
• NITRAprint
• NITRAflash
• Computer with NITRAwin
• Modem
The memory of the electronic control system
permanently stores records of the last 40 programs.
For effective hard-copy documentation of batches and
for checking previously executed programs, a
NITRAprint printer can be connected to print out a record
immediately after completion of a program, or to print out
records from the memory. If a PC is connected, the
NITRAwin program can also transfer the records to the
PC for permanent archiving of all results and print out
any results as required.

7 Installation
For the steps required to prepare for and carry out the
setup and installation of the autoclave, see the separate
instructions contained in "Setting up the
DAC PROFESSIONAL".
7.1 Installation requirements
The autoclave should be set up in a dry place which is
protected against dust.
The base should be stable and flat and capable of
supporting the weight of the unit
(unloaded weight = 43 kg).
The space required by the autoclave can be seen from
the external dimensions (see Section 4.1). A minimum
additional space of 10 cm should be allowed on both
sides and above the autoclave in order to ensure that
heat can escape.
The electrical power supply should be a separate
230V AC circuit with a 16A fuse.
This autoclave operates with a blower for the cooling
system, on the rear side of the unit. If there is a
restriction of the escape of heat above the unit, this can
impair the functioning and shorten the service life of the
autoclave. We therefore urgently advise our users not to
install the autoclave in an area where there is not
sufficient circulation of air.
If the user decides to install an automatic one-way
system, it is necessary to have a connection to the waste
water plumbing near the autoclave, preferably a wall
outlet (NW 40) or a sink drain (standard length of drain
hose = 2m, with an outer hose diameter = 15 mm).
A 2 meter long drain hose (Art. No. 61 26 556) is
supplied with the unit. The required connectors must be
ordered according to the given practice situation. The
work surface on which the autoclave stands must be
higher than the outlet so that the drain hose can be run
to the drain continuously downward and without bends
and twists which could prevent the water flowing out
freely. At the same time, the work surface must provide
convenient access to the autoclave and the display must
be clearly visible.
The autoclave must be supplied with feed water from the
integrated dual-chamber water tank, with fresh water
and waste water chambers. However, please note that
this will require additional space for the water treatment
system.

7.2 Transport straps
Lift the autoclave out of the packaging using the
transport straps. The straps themselves are each
removed by unscrewing the two retaining screws, which
must then be screwed firmly back in place without
washers.
7.3 Alignment
In order to operate properly, and to allow unimpeded
return flow of condensate into the steam generator, the
autoclave must be installed so that it definitely slopes
toward the rear. First install the autoclave in a horizontal
(level) position and check that this position is in fact
horizontal with a spirit level at the chamber flange. Then
extend the front feet to lift up the front side of the
autoclave by screwing them out by at least three turns.
7.4 Power supply connection
The unit power cord must be connected to a
230 V, 50 Hz electric outlet. The power rating of the
autoclave is 2100 W. In order to avoid overloading the
building electricity supply, we recommend using a
separate electrical circuit fitted with a 16 A fuse and
optionally protected with a type RCCB (residual current
circuit breaker) with a tripping current of 30 mA.
7.5 Outlet connection for one-way water
DAC PROFESSIONAL operates only in the one-way
water system, i.e. used feed water (hereinafter referred
to as "waste water") is not recycled. Waste water is
collected in the drain tank. As an option, the autoclave
can be connected directly to the waste water plumbing
via the one-way outlet. A retrofit kit is connected to the
rear wall of the autoclave for this purpose. Its drain hose
must be run to the drain continuously downward and
without bends or twists and must not exceed a max.
length of 2 meters. The outlet must be connected to an
existing sink drain, or to a separate NW40 drain pipe with
use of the wall-mounted drain.
7.6 Internal water supply with feed water
If the user decides for internal supply of the autoclave
with feed water, this water is taken from the right
chamber of the built-in water storage tank. To install the
internal feed water supply system, connect the hose to
the feed water connection of the water tank on the rear
side of the autoclave. For this variation of water supply,
the autoclave is delivered ready for installation. To fill the
feed water tank, remove the cover of the tank and fill the
right chamber with feed water up to the maximum mark.
