a) Not exposed to risks of explosion and not pressurised.
b) Temperature between 10 and 40 °C.
c) Relative humidity between 30 and 75 %.
d) Atmospheric pressure between 700 and 1060 hPa (700 ÷ 1060 mbar)
a) Conformity to the IEC 60364-7-710 standard (electrical systems on premises used for
medical purposes).
b) Single phase power supply 230 V ± 10% frequency 50/60 Hz
Suitable to supply required power.
Single phase power supply voltage: 230 V
Maximum variation allowed in power supply voltage: ± 10 %
Maximum absorbed power: 1.45 kVA
The dental unit is preset for a permanent connection to the electrical system by means of a
suitable power terminal.
A differential bipolar switch of at least 16 A - 250 V and differential tripping current I
A, compliant with the European standards regarding the device, must be installed upstream
the equipment.
If an air compressor is to be installed, an electrical power supply and protection independent
from the dental unit are necessary.
In compliance with national drinking water regulations.
In compliance with national drinking water laws.
Properly filtered and decalcified household drinking water for cup and basin
a) hardness: 0 ÷ 20 °F (French degrees)
15 ÷ 20 °F (French degrees) – for systems with probe level control
b) pressure: 300 ÷ 500 kPa (3 ÷ 5 bar)

c) capacity: 3 l/min at 450 kPa (4.5 bar)
In case of pressure under 300 kPa (3 bar) a device to ensure the required pressure (autoclave)
should be inserted upstream the dental unit. In case of pressure over 500 kPa (5 bar), an
adequate pressure reducer must be installed upstream the dental unit.
The power supply line must be equipped with a cut-off valve
To prevent the risk of polluting the water system caused by any dental unit liquid reflux, we
recommend powering the unit via a power supply system in conformity with conform the
EN1717 standard, which guarantees the physical separation of the mains water from the
instrument spray hoses.
Installed in a ventilated and hygienically protected area not collecting water draining of the
surgery suction unit and away from sources of heat.
a) Compressed air at pressure between 550 e 700 kPa (5.5 ÷ 7 bar)
b) Capacity over or equal to 50 l/min at 400 kPa (4 bar)
c) Dew point under or equal to 10 °C
The power supply line must be equipped with a cut-off valve
Should the dental unit be connected to a centralised surgical suction system, the system
should be canalised. For a SINGLE SURGERY suction system however, it is sufficient to connect
the suction unit to the dental unit via the provided pipe. The surgical suction system should
drain suctioned air externally into a free atmosphere for environmental hygiene reasons.
- Air flow: 300 l/min.
- Low pressure limit: 10 kPa (0.1 bar).
The drain exhaust duct must be manufactured with a slope of approximately 1 cm for every
metre of distance of the dental system from the central exhaust column and it must also be
equipped with an inspectable siphon
