Operating Instructions DAC Universal 2.1Electrostatic discharge
båÖäáëÜ
2Safety instructions
2.1 Electrostatic discharge
Protective measures
Electrostatic discharge (abbreviated: ESD – 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
Endangered regions are indicated on the unit by 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.
IMPORTANT
This product is intended for use by qualified healthcare professionals
only. Before operating the DAC Universal, carefully read and follow
these instructions and save them for future reference. Observe all
cautions.

2.1Electrostatic discharge Operating Instructions DAC Universal
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 over 10 amps. They are not hazardous for humans because they last
for only several nanoseconds.
Tip: 1 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, arc-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 breakdown of
the structures, thus leading to a discharge current that melts the chip in
the affected areas. Damage to individual integrated circuits may cause
malfunction or failure of the unit.

3.1 Functions
The DAC Universal reduces the risk of cross-contamination and ensures
the proper maintenance of your instruments.
DAC Universal automatically cleans, lubricates, and sterilizes 6
instruments in about 18 minutes with the Standard lid. The instruments
can be used again immediately after cooling down.
The Basket lid is available optionally for the cleaning and sterilization of a
maximum of 5 unwrapped solid instruments.
The optional Flex lid is available for the cleaning and disinfection of a
maximum of 6 unwrapped instruments. The instruments reprocessable
on the Flex lid include the following:
● Ultrasonic handpieces
● Scaler tips + torque wrenches (for scaling and periodontics)
● Nozzles for multifunctional syringes
● Nozzles for airflow handpieces
These instruments are referred to as Flex lid instruments.
The number and placement of the different adapters is optional.
Exception: The Flex lid can contain a maximum of 3 scaler tips of Sirona
and / or Satelec simultaneously, which should not be placed next to one
another.
3.1.1 Functions with the Standard lid
The unwrapped instruments are reprocessed as follows using the
adapters on the Standard lid.

Internal cleaning
Internal cleaning ensures that the channels of the instruments are rinsed
thoroughly. For the internal cleaning of the instruments, water is forced
through the channels using compressed air.
The channels are rinsed with water 12 times during a cleaning cycle.
Oil care
After the internal cleaning, the transmission channels of the instruments
are lubricated with oil. The amount of oil used is precisely calculated for
one patient treatment which is on average 20 to 30 minutes. To ensure
trouble-free operation, accumulated operating time of rotating
handpieces treated in DAC Universal shall not exceed 10 minutes.
External cleaning
The instruments are first cleaned at least 3 times with unheated water in
a pulse-wash procedure (multicyclic cleaning method). In the subsequent
and final pulse-wash cycle, the instruments are cleaned with warm water
heated by steam.

Sterilization
After external cleaning, the chamber is heated to 134 °C (273 °F) and the
instruments are sterilized. Saturated steam is forced into the chamber
and then extracted back through the drive, air, and water channels (if
available) of the instruments. This is known as the back-flush method.
2 different sterilization programs are available:
● 134 °C (273 °F) with a sterilization time of 3 minutes
● 134 °C (273 °F) with a sterilization time of 18 minutes
To select the program, see "Programs and program selection [ → 27]".
For instructions for reprocessing unwrapped rotating handpieces see
"Reprocessing with the Standard lid [ → 90]".
3.1.2 Functions with the Basket lid
5 solid instruments, instruments without cavities, can be reprocessed in
the DAC Universal with the optional Basket lid.
External cleaning with NitraClean cleaning tablet
Solid instruments are first cleaned externally 3 times with unheated water
using a NitraClean tablet. This is necessary to perform the cleaning
properly. The external cleaning is done using the pulse-wash method
(multicyclic cleaning method). In the subsequent and final pulse-wash
cycle, the instruments are cleaned with warm water heated by steam.
WARNING
According to the European EN 13060 standard, non-solid instruments or
instruments with cavities may not be sterile after a cycle in the Basket
lid.

Internal cleaning
Internal cleaning ensures that the channels of the instruments are rinsed
thoroughly. For the internal cleaning of the instruments, water is forced
through the channels using compressed air. The channels are rinsed with
water 12 times during a cleaning cycle.
External cleaning
The instruments are first cleaned 5 times with unheated water in a pulse-
wash procedure (multicyclic cleaning method).
Then warm external cleaning is conducted up to 120 °C (248 °F).
The total number of washes is 5 cold and 1 warm, in total 6 washes.
Thermal disinfection
After external cleaning, the chamber is heated to 134 °C (273 °F) and the
instruments are thermally disinfected. Saturated steam is forced into the
chamber and then extracted back through the available air and / or water
channels of the instruments. This is known as the back-flush method.
2 different thermal disinfection programs are available:
● 134 °C (273 °F) with a holding time of 3 minutes
● 134 °C (273 °F) with a holding time of 18 minutes
