1.1 Safety
+
It is essential that you comply with the warning and safety
information contained in the Installationsvoraussetzungen.
All such information is highlighted by the captions NOTE,
ATTENTION, and CAUTION.
For reasons of product safety, only original Sirona accessories approved for this product, or accessories from third parties approved by Sirona, may be used. The user is responsible for dangers resulting from the use of non-approved
accessories.
If any devices not approved by Sirona are connected, they
must comply with the applicable standards, e.g.:
• IEC 60950 for information technology equipment and
• IEC IEC 60601-1 for medical electrical equipment
In case of doubt, contact the manufacturer of the system
components.
Any person who assembles or modifies a medical electrical
system complying with the standard IEC 60 601-1-1 (safety
requirements for medical electrical equipment) by combining it with other equipment (e.g. when connecting a PC) is
responsible for ensuring that the requirements of this regulation are met to their full extent for the safety of the patients,
the operators and the environment.
The floor must have a minimum loading capacity of 0.5N/
cm².
Interference of electromedical devices caused by radio telephones:
To ensure the operational readiness of electromedical devices, the use of mobile radio telephones in the practice or
hospital area is prohibited.
Electromagnetic compatibility: The unit should not be operated in the immediate vicinity of other devices. If this
proves to be unavoidable, the unit should be monitored to
ensure that it is used properly.
bеЦдблЬ
The loudspeaker socket of the monitor may be connected
only to a device which complies with IEC 60950 (e.g. PC) or
IEC 60601-1, and under no circumstances e.g. to a stereo
system etc.
The floor must be flat and level (DIN 18 202). A steel plate
must be used for uneven floors (see Section 1.5, "Mounting
plates" on page 12).

1.2 Media quality
Water quality
Lime deposits and corrosion residues in tap water can lead
to the following malfunctions:
• Premature clogging of the filters in the unit
• Rapid clogging of the fine water paths and jets in the
treatment instruments
For these reasons, the following points must be observed:
• If the water hardness exceeds 12° dH (=2.15mmol), install a water softener.
• Set dilution hardness to 8° dH (1.43 mmol).
• Install a conventional fine filter.
Fineness: >80µm (0.08mm).
• Installation must be performed in compliance with the
recommendations of the national installation requirements (e.g. EN1717/DIN 1988).
• The water quality must comply with the national requirements for drinking water.
• The connection must be made to cold water.
Air quality
Oil-free, dry and hygienically perfect air is required for driv-
bеЦдблЬ
ing the highspeed handpiece, for cooling the burr drives
and for the cooling spray.
Suction pipe
Install steam trap K.
With a vacuum of pu >0.18 bar back pressure, the treatment center must be retrofitted with the “Vacuum limiter”
retrofit kit (Order No.: 59 68 826).

• Observe the national regulations for electrical installations (e.g. VDE 0100, VDE 0100, Part 710).
• Observe the national regulations for water supply installations (e.g. EN 1717, DIN 1988) and sewage installations (e.g. EN 12056-1).
• For the suction pipe, observe the instructions in the
Suction Machine Installation Instructions.
• For fastening the pipe ends in the installation field, we
recommend using an installation template. They can
be ordered from Sirona under REF 33 15 830.
If necessary, you can also prepare the template yourself based on the above sketch (not true to scale!).

Supply above the floor, "above-floor installation"
The supply pipe ends, corner valves and cables must be
routed as shown above.
The retrofit kit for above-floor installation (33 17 265) is
required for installation.
For cleaning, rinse the air and water pipes thoroughly (metal
chips!).

1. The top edges of the corner valves for air and water
must not protrude more than 60mm above the upper
surface of the finished floor.
2. The suction and drain pipes must be flush with the upper surface of the floor (a deviation of +5mm is permissible).
Internal diameter for both pipes: 36,5mm.
3. The electrical cables must protrude at least 500 mm.

1.4 Underfloor installation of SIVISION connections
Important information for the installer
Depending on the prevailing local conditions, the existing
cable set can be installed in the cable duct of an underfloor
installation by an installer prior to the installation of the dental treatment center. In this case, please observe the following:
Proceed with extreme care when running the cables. Particularly cables L15 and L38 are very sensitive, and must
never be kinked or twisted. The cables must not overlap or
cross one another.
RS232 (L37) and the XGA cable (L38) are not yet cut to
length and terminated on the PC side. It would be impossible to pull the cables through when installing them under
floor level if a sub D connector were already connected.
These cables should always be pulled.
Free length A of cables at the treatment center end:
Length A = 600mm
If S video cable L15 is equipped with both a female and a
male connector, make sure that the female connector
(socket) points to the connection box of the treatment center.
bеЦдблЬ
2. Pull cables L15, L37 and L38 as well as the audio and
protective ground wire cables from the treatment center
through the cable duct to the location of the SIVISION
PC.
Save the accessory parts for final installation!
1. Bend the wire at the front end of cables L37 and L38 to
form a hook.

For especially uneven floor conditions,
a steel chair plate is available to compensate for the irregularities of the floor
(REF 58 71 913).
For floors which do not permit permanent connection of the unit (e.g. demo operation at a fair),
installation on a steel demo plate is possible
(REF 58 66 301).

a. If an HF electrosurgical unit is integrated, it must emit electromagnetic energy in order to function properly. Any electrical
devices located nearby may be influenced whenever the HF surgical unit is active. According to IEC 60601-2-2, Chap. 36, no
limit values have been defined for active HF surgical units. They are therefore classified as Group 1 devices according to
CISPR 11.
Class A
compliant
a
The customer or user of the UNIT should make sure that it
is used in such an environment.
The UNIT uses HF energy only for its internal function. The

a. The higher frequency range applies at 80 MHz and 800MHz.
b. The field strength of stationary transmitters such as the base stations of radio telephones and land mobile services,
amateur radio stations as well as AM and FM radio and television broadcasting stations cannot be accurately predetermined. An investigation of the location is recommended to determine the electromagnetic environment resulting from
stationary HF transmitters. If the field strength measured at the UNIT location exceeds the conformance level specified
above, the UNIT must be observed with respect to its normal operation at each application site. If unusual performance
characteristics are observed, it may be necessary to take additional measures such as reorientation or repositioning of
the UNIT.
c. A frequency range of 150kHz to 80MHz results in a field strength of less than 3 V/m.

For transmitters whose maximum nominal output is not
specified in the above table, the recommended working
clearance d in meters (m) can be determined using the
equation in the corresponding column, where P is the maximum nominal output of the transmitter in watts (W) specified by the transmitter manufacturer.

Annotation 2
These guidelines may not be applicable in all cases. The
propagation of electromagnetic waves is influenced by
their absorption and reflection by buildings, objects and
persons.
