Warnings
This product is intended for use by licensed healthcare professionals only. Before operating the DAC UNIVERSAL,
carefully read and follow these instructions and save them for future reference. Observe all cautions and warnings.
Precautions
Oil, water and hot steam are discharged through the drain from the autoclave.
Heat
Note that the instruments are hot after the cycle has ended. Allow them to cool before handling.
Ventilation
Operate the steriliser in a well-ventilated area. Ventilation requirements will vary with room size, frequency of use, etc.
Oil
Sirona Dental Systems GmbH recommends our users at all times to use the type of oil that is recommended by the
manufacturer of the instruments. Please contact the manufacturer of your instruments for further information on the type of
oil to use.
Water
Periodically, it is necessary to add water to the DAC UNIVERSAL.
It is important to make sure that the water is added to the water tank, cf. appendix 1.
To ensure long durability of the instruments and the autoclave, it is important only to use demineralised or distilled water in
the DAC UNIVERSAL.
Tap water contains a very high level of calcium/lime scale that will damage both the instruments and the autoclave.
The DAC UNIVERSALrequires a maximum water conductivity of 3.0 S/cm (micro Siemens).
Drying
If the instruments are to be stored for a longer period (e.g. during the weekend), it is important that they are blown through
with compressed air (max. 3.2 bar/46.4 psi) to remove the condensate water from the instruments.
Condensate water can cause corrosion on instruments.
Compressed air
The compressed air to the DAC UNIVERSAL must be dry and must not contain any oil remains.
Please contact the supplier of your compressed air unit, if you have any questions regarding this issue.
It is necessary to install an air filter before the DAC UNIVERSAL in order to prevent particles from the air to be let into
the DAC UNIVERSAL. Please contact your supplier regarding Sirona air filter (order number 60 78 575).
Power supply
The DAC UNIVERSAL is operated with an AC-input power supply of 90-120 / 190-240 volt, 50/60 Hz, grounded outlet 
1100 W.

Purpose of this manual
The purpose of this manual is to provide the user with sufficient information about the DAC UNIVERSAL in order to use it
effectively in the dental clinic immediately after delivery. We recommend that you study appendix 1 thoroughly before using
the DAC UNIVERSAL the first time. In this way you will have a better understanding of how the DAC UNIVERSAL
functions.
It is not allowed to use the DAC UNIVERSAL in another way than described in this instruction for use.
1.1 Safety and technical Information
1.1.1 ESD protective measures
ESD stands for ElectroStatic Discharge.
CAUTION: Connector pins or sockets bearing ESD warning labels must not be touched or interconnected
without ESD protective measures.
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.
1.1.2 About the physics of electrostatic charges
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.

DAC UNIVERSAL USER MANUAL

60 53 362 D3472 9

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 centimetre (0.39 inches) 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 millimetre.
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.

1.2 Functioning
According to EN13060 the DAC UNIVERSAL is classified as a Class S autoclave for hand pieces, turbines and solid
instruments which fit in the basket.
The DAC UNIVERSAL automatically cleans, lubricates and sterilises turbines, handpieces and contra-angles (in the
following designated instruments).
In approx. 12 minutes 6 instruments will be cleaned, lubricated and sterilised and are ready for use again after cooling
down.
A basket (auxiliary equipment) for flushing and sterilization of solid instruments is available.
The DAC UNIVERSAL reduces the risk of cross-contamination and ensures optimum maintenance of the instruments.
Maximum length of hand-pieces and turbines:
The six adapter positions are each marked with dots, which symbolise the adapter-position-number on the adapter lid. On
position 1 on the lid the instruments must not be longer than 145 mm/5.71 inches (total length of instrument and adapter).
The maximum length on position 2-6 is 160 mm/6.30 inches (total length of instrument and adapter).
The DAC UNIVERSAL Autoclave contains an absolute pressure sensor.
The absolute pressure sensor means that the pressure shown in the display (see description 1 in appendix 2), when the
machine is open, is equal to the actual pressure in the surrounding environment.
When the autoclave is on, but inactive, the pressure indicated in the display always will be about 1 bar/14.5 psi at ocean
level.
At high barometric pressure the pressure will be about 1.03 bars and at depression it will be about 0.98 bars.
Furthermore the absolute pressure sensor means that the autoclave can be placed in areas situated high above the
ocean-level (i.e. in mountain areas) without showing errors because of difference in pressure.
(i.e. the autoclave will adjust itself to differences in the surrounding pressure.)
1.3 Cleaning of non-wrapped instruments
The instruments are cleaned internally as well as externally.
When using the basket for solid instruments, the instruments are only cleaned externally.
Internal cleaning
The internal cleaning ensures that the spray channels of the instruments are cleaned.
The instruments are cleaned, by flushing the internal spray channels with water and air pressure to ensure, that no dirt is
left in the channels.
The internal spray channels are flushed 4 times during the internal cleaning.
External cleaning
The DAC UNIVERSAL uses a cleaning procedure called pulse wash. The pulse wash uses water under pressure.
The DAC UNIVERSAL autoclave cleans 1 time with cold water and 1 time with warm water, thereby removing biofilm on
the instruments easier and more quickly. It is possible to increase the number of washes to 6 times via the menu system.
Solid instruments are cleaned externally by means of the pulse wash.
It is possible to increase the effect of the pulse wash by means of a Nitra Clean tablet (order number 60 53 842). This
tablet is to be introduced to the chamber before the cycle has started.
We recommend use of one NitraClean tablet once a day, based on 10 cycles per day.
We recommend that you do NOT use a NitraClean tablet in a cycle where Sirona SiroPure or other oil-free
instruments are placed on the lid.

1.4 Lubrication of non-wrapped instruments
Prior to the sterilization cycle the drive channels are cleaned and lubricated.
When using the basket for solid instruments the lubrication cycle should be omitted.
Once the cycle has finished the lubrication cycle is automatically switched on again.
i
NOTE
The amount of oil that is supplied to each instrument during a DAC Universal cycle is designed for the instrument
undergoing a DAC cycle between each patient.
1.5 Sterilization of non-wrapped instruments
At the beginning and the end of the sterilization, the instruments are exposed to both an internal and an external
sterilization cycle.
During the cycle of internal sterilization, a very high level of pressure of saturated steam is generated in the autoclave
chamber which is extracted backwards through the drive and spray channels of the instruments.
The flow of steam-pressure is repeated 16 times in total, throughout the cycle. This cycle is called back-flush.
In addition to this, an external sterilization of the instruments is carried out.
Here the instruments are exposed to the temperature and steam pressure as chosen in the program. It is possible to
choose between three different sterilization programs: 121C/250F with a sterilization time of 15 minutes, 134C/273F
with a sterilization time of 3 minutes and 134C/273F with a sterilization time of 18 minutes.
Sterilization control system:
The sterilization control system works by regulating the pressure and at the same time controlling the corresponding
temperature.
This means that if the temperature or the pressure is below or above the limit values of the sterilization an error will appear
in the display.

1.7 Processing handpieces and turbines
The DAC UNIVERSAL is made for immediate use of handpieces and turbines. This means that the handpieces/turbines
are transported directly from the dental chair to the DAC UNIVERSAL where they are introduced into the machine.
It is recommended to pre-clean the instruments if the handpieces and turbines are very dirty or if the handpieces and
turbines have been left to dry before processing in the DAC UNIVERSAL.
During the time of handling the handpieces/turbines the dirt, blood etc. will dry and will increase the need for pre-cleaning.
After the process in the DAC UNIVERSAL and after cooling down, the handpieces/turbines are ready for immediate use in
all dental treatments.
In case the instruments are not to be used immediately it is recommended to bag the handpieces/turbines in e.g. dental
wrapping bags, which clearly indicates date and time and that the instruments have been processed in the DAC
UNIVERSAL and that they are not to be used for surgical procedures.
NOTE: Please always follow the demands of your own specific country.
The procedure is described more in detail below:

2. Installation of the DAC UNIVERSAL
The purpose of this chapter is to provide the user with information about how the installation of the DAC UNIVERSAL
should take place.
It is recommended that the instruction manual be examined thoroughly before the installation is carried out.
Please note that the autoclave must be left to warm to the ambient temperature before it is connected (i.e.
between 20oC/68o F and 30oC/86o F).
The DAC UNIVERSAL must NOT be stored in temperatures lower than 1oC /33.8o F.
NOTE: Only Sirona trained technicians with a Sirona training certificate are qualified to perform the installation, service,
repair and maintenance of the DAC Universal.
2.1 Requirements concerning placing
The DAC UNIVERSAL should be placed in an open space on a horizontal position/surface.
Place unit in a well ventilated area on a level heat resistant counter top near both compressed air and an electrical source.
Recommended minimum space to the wall: 10 cm / 3.94 inches.
Furthermore, there must be enough space to allow the autoclave to open (upright).
Total height of the DAC UNIVERSAL when open: 60 cm. / 23.62 inches .
When closed the autoclave is 35cm / 13.78 inches x 36cm / 14.17 inches (H x W).
For your information the mains disconnecting device is the appliance coupler.

2.2 How to install the DAC UNIVERSAL?
Before the DAC UNIVERSAL is ready for use the following connections are required:
AC input: 90-120 and 190-240 volt 50/60 Hz, grounded outlet 1100 W
The DAC UNIVERSAL is supplied with a main lead with plug, which must be connected to the autoclave
(see figure 1 in section 2.2.3).
When the DAC UNIVERSAL is connected to electricity the lid will then open and error 92 can possibly occur; in this
case 
Compressed air 5-8 bar/72.5-116 psi; flow: 60 litres/2.1 cubic ft pr. min.
A tube size 6/4mm (0.24/0.16 inches) is required for the connection between the DAC UNIVERSAL and the
external compressor.
The compressed air tubing is inserted in the top screw coupling (see figure 1 in section 2.2.3).
The tube must be held in while simultaneously the nut is fastened with a 12mm/0.47 inches wrench.
To dismantle the tube the nut is unfastened and the tube can easily be drawn away.
The DAC UNIVERSAL has a built-in pressure regulator, therefore the autoclave will function at any level between 5
and 8 bar/72.5-116 psi.
The compressed air is used during the cleaning and lubrication cycle.
The compressed air is specifically used for flushing the spray channels during internal cleaning and for the pulse wash
during the external cleaning.
Furthermore the compressed air is used for distributing the oil during the lubrication cycle.
The compressed air to the DAC UNIVERSAL must be dry and must not contain any oil remains.
Please contact the supplier of your compressed air unit, if you have any questions regarding this issue.
i
NOTE: It is necessary to install an air filter (order number 60 78 575) (20 microns) before the DAC UNIVERSAL, in
order to be sure that the air is clean for the protection of the machine.
Drain for used water, steam and oil
Residual water emerges through the drain outlet.

Therefore the drain outlet (the middle screw coupling - see figure 1 in section 2.2.3) must be connected with a drain
tank (order no. 60 78 526 includes 3 meter (118.11 inches) of PFTE (heat resistant) tube 6/4mm (0.24/0.16 inches)
and mounting instructions) in order to collect the residual water.
For this connection you must use a 6/4mm (0.24/0.16 inches) PTFE tube.
The PTFE tube must not be longer than 3 meter/118.11 inches.
The fitting and the removal of the tube are accomplished in the same way as the connection of compressed air.
The tube must be connected without pressure to the drain.
When connecting the drain tank to the drain it is important to fix the connecting piece thoroughly.
Be aware not to handle the drain tube when it is hot or the machine is running.
The waste from the drain should be handled following Universal Precautions as well as any applicable waste disposal
regulations.
Warning
Oil, water and hot steam are discharged through the drain from the autoclave.
If using another type of tube than the PFTE tube, the tube must be steam resistant at approx. 134ºC/273ºF.
How to supply water to the water-tank
One of the following connections must be made:
A) Constant connection to demineralised/ distilled water
Dismantle the stopper on the water inlet.
The constant connection of demineralised/distilled water is through a 6/4mm (0.24/0.16 inches) tube connected to the
bottom screw coupling (see figure 1 in section 2.2.3).
i
NOTE: It is necessary to install a water filter (20 microns) before the DAC UNIVERSAL, in order to be sure that the
water is clean for the protection of the machine.
The fitting and the dismantling of the tube are done in the same way as the connection of compressed air.
