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.

1 nanosecond

= 1/1,000,000,000 second

= 1 billionth of a second

Sirona Dental Systems GmbH

Operating Instructions DAC PROFESSIONAL

61 33 826 D 3554

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.
