6681006 D3708
D3708.201.01.01.0204.2019 13
2.1 Electrostatic discharge
WARNING
Risk of contamination!
Electrostatic discharge can affect the cleaning outcome.
Protective measures
ESD stands for ElectroStatic Discharge.
Electrostatic discharge from people can damage electronic components
when the components are touched. Damaged components usually have
to be replaced. Repairs must be performed by qualified personnel.
Measures to protect against ESD include:
● Procedures to avoid electrostatic charging via
– air conditioning
– air humidification
– conductive floor coverings
– non-synthetic clothing
● discharging the electrostatic charges from your own body through
contact with
– a metallic unit casing
– a larger metallic object
– any other metal part grounded with the protective earth
● Wearing an antistatic band that creates a connection between the
body and a protective ground wire.
Areas at risk are indicated on the unit with the ESD warning label:
We recommend that all persons working with this system are made
aware of the significance of the ESD warning label. A training course
should also be held to inform users about the physics of electrostatic
charges.
Physics of electrostatic charges
An electrostatic discharge requires prior electrostatic charging.
There is a danger of electrostatic charges building up whenever two
bodies rub against each other, e.g. when:
● walking (soles of shoes against the floor) or
● moving (chair casters against floor).
The amount of charge depends on several factors. The charge is:
● higher at low air humidity than at high air humidity, and
● 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)

2.1 Electrostatic discharge
Dentsply Sirona
Operating Instructions DAC Universal

D3708.201.01.01.0204.2019
The transient currents resulting from these discharges have a
magnitude of over 10 amps. They are not hazardous for humans
because they last for only several nanoseconds.
Note: nanosecond = 1/1,000,000,000second = 1billionth of a second
Voltage differentials exceeding 30,000 volts per centimeter may lead to
a charge transfer (electrostatic discharge, lightning, spark-over).
Integrated circuits (logical circuits and microprocessors) are used in
order to implement a wide variety of functions in a device. 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. Integrated circuits that
are connected to wires leading externally are therefore particularly at
risk from electrostatic discharge.
Even voltages that are imperceptible to the user can cause spark-over
of the layers. The resulting discharge current melts the chip in the
affected areas. Damage to individual integrated circuits may cause
malfunction or failure of the unit.

D3708.201.01.01.0204.2019 15
2.2 Caution symbols on the device
Meaning: Warning of danger
This symbol is found on the back of the DAC Universal next to:
● the RS232 interface and the LAN interface: External computer
hardware that is connected to this serial interface must be labeled
"The connected device must comply with the UL 1950 and IEC/EN
60950 standards and must be connected only to safety extra low
voltage (SELV) circuits."
Meaning: Warning of a hot surface
2.3 Flammable materials
WARNING
Risk of explosion!
Never use the DAC Universal in the presence of flammable
anesthetics or gases.
WARNING
Risk of explosion!
Do not hold the NitramOil #2 bottles near an open flame.
2.4 Reducing the risk of burns
CAUTION
Risk of burns!
The bottom plate of the DAC Universal can be hot.
CAUTION
Risk of burns!
Never hold your head directly over the DAC Universal when it opens,
as steam may emerge from the device.
CAUTION
Risk of burns!
Even when the lid of the DAC Universal is partly or completely open,
the instruments are still hot. Allow the instruments that become very
hot during the process to cool down.
CAUTION
Risk of burns!
The metal part of the lid is very hot. Always touch only the plastic part
of the lid.

D3708.201.01.01.0204.2019
CAUTION
Risk of burns!
The drain hose, filter housing, drain filter and drain tank are very hot
during the reprocessing cycle. Switch the DAC Universal off and let it
cool down (about 15 minutes) before emptying and cleaning the drain
tank or cleaning or replacing the drain filter.
CAUTION
Risk of burns!
Note that the temperature of the drain water is hot (approx. 100 °C).
CAUTION
Risk of burns!
The drain tank may contain hot water. Make sure that you do not tip it
over.
2.5 Instruction of practice personnel
WARNING
The personnel responsible for the operation and maintenance of the
DAC Universal must have received instruction on the safe operation
of the DAC Universal from a service technician trained by the
manufacturer. Following the initial instruction from the service
technician, a party must be named in the practice who is responsible
for supporting and training the personnel charged with operating and
maintaining the DAC Universal.
2.6 Installation requirements
CAUTION
Risk of crushing
The overall height of the open DAC UNIVERSAL is 59 cm.
The recommended minimum height for installing the DAC Universal is
70 cm, in order to prevent crushing and injuries when removing the lid
and hitting any hanging cabinets.
WARNING
Risk of contamination!
Please note that the DAC Universal must have warmed up to room
temperature before being operated. The DAC Universal may NOT be
installed in operating state in rooms with temperatures below 0°C,
otherwise ice may form.
WARNING
Risk of contamination!
After installation, the DAC Universal must be acclimatized before use
so the cleaning result is not affected.

Only the loads listed may be reprocessed in the DAC Universal.
The DAC Universal cleans, lubricates and disinfects up to 6 turbines
and straight and contra-angle handpieces automatically in approx. 15
minutes. The dental handpieces are then immediately ready for use.
IMPORTANT
It is not possible to reprocess 6 instruments without spray channels
simultaneously on the Blue lid, as this will result in error 1506.
The number of different adapters is optional.
Please refer to the adapter operating instructions for details on the
placement of the different adapters.
For the cleaning and disinfection of up to 6 unwrapped instruments
(Green lid instruments), the Green lid is optionally available.
The following instruments can be reprocessed on the Green lid:
