1. GENERAL INFORMATION
Linea Patavium offers a wide range of instruments to be positioned in the five existing housings.
Linea Patavium is available in two versions, with a spittoon unit suspended over the chair or on the floor.
Its special kinematism allows for reduced vertical travel of the instrument return arms, total self-balancing in the
maximum extraction position and maximum freedom of the feed tubes in all directions.
All the top part of the spittoon unit is painted resin, the basin is ceramic and has no interstices for better cleaning and
increased hygiene. The cannulae to wash the basin and fill the cup can be easily removed and are autoclavable.
The high-speed suction tubes and connections are easy to remove for disinfection purposes. At the same time, the filter
can be extracted in an easy and hygienic manner too.
Linea Patavium can be combined with patient chairs Moon, Arcadia EXT, Arcadia P and Swan, compliant with Directive
93/42/EC and its successive amendments and additions produced by O.M.S.
The CE 0051 certification applies to Linea Patavium only.

SAFETY
RULES
DANGER
To prevent the risk of electrical shocks, the equipment must be connected
exclusively to power lines provided with a grounding system according to the law in
force in your country.
DANGER
Before powering the equipment after installation, a repair or technical service, check
and, if necessary, hook up the connection of the grounding cables to the screw
identified by the grounding system symbol.

OMS LINEA PATAVIUM S.T.01/3X ED.0 REV.8 09/2017

DANGER
The device must be installed in rooms featuring electrical systems that are up to
local code.
DANGER
The installation of the dental unit has to be done by an OMS authorised technician;
the choice of the pipelines is up to the designer of the electrical system and they
have to be placed by a qualified technician according to the law in force in the
country.
DANGER
Never allow the device to be used by non-professional operators or anybody who has
not read the instruction manual.
Always check that the device is in good condition.
WARNING
Do not use the device if any part of it is defective or worn. If this is the case, call in
authorised O.M.S. technical personnel.
WARNING
Have defective or worn parts replaced with original, warranted O.M.S. spare parts
only.
DANGER
Do not operate the equipment on patients with pacemakers.

DANGER
In the version with the spittoon unit on the floor, when the chair moves upwards, check the
position of the patient's arm on the armrest, to prevent the arm from hitting the basin.
DANGER
When moving the chair, both in manual and especially in automatic mode, do not place hands
and feet near the bottom of the chair to avoid crushing hazards, read the chair instructions
carefully.
WARNING
During automatic chair movement, the operator must stand near the dental unit.

3. COMMAND - CONTROL - WARNING
SAFETY SYSTEMS
The unit is equipped with safety devices that minimize the risk of collision during the movement of the chair, in
particular there is a safety on the basin floor water group in version, which intervenes when the tray is rotated
by the side of the chair, limiting the ascent of the chair at a defined height.
DANGER
In the version with a floor water group during the ascent of the chair check the
positioning patient on the arm to prevent the risk of crushing with the basin.
Note:
During any automatic chair movement (reset, memory placement or rinse position) by
pressing any patient chair command (from the dental unit or push off of the foot controller)
the chair stops immediately.
The movement of the chair, either at power-up that in normal use, can be prevented if one or
more safety systems are active
Note:
Lifting the assistant's table locks the pantograph and backrest downward movement.

INSTRUMENT TABLE
The instrument table can feature up to four instruments (syringe included) and comprises three different
sectors.
The sector Aincludes the instrument unit controls and options, if any. The general board for dental unit
operation is installed here along with all the electrical connections of the instruments.
The sector Bincludes the instrument solenoid valve unit where all the adjustment devices are well visible. A
description of the function of each device is provided in the instrument module chapters. Adjustments that are
not equipped with a handle must be made by authorised O.M.S. technicians.
The sector Cis the portion of the table where instruments are positioned.

INSTRUMENT GENERAL FUNCTIONS
3.2.2.1. SPRAY
Spray is pre-selected entering the command on the keyboard.
The spray function is then operated by pressing the rheostat lever (A) with the tool on
(standard configuration).
The water delivered to the spray is regulated by rotating the tap located under the relevant instrument
module: when turned anticlockwise, the flow of water to the spray is gradually reduced; when turned
clockwise, the opposite applies. We recommend not using other regulation devices located alongside the spray
tap.

OMS LINEA PATAVIUM S.T.01/3X ED.0 REV.8 09/2017
20
3.2.2.2. CHIP BLOWER
After extracting the instrument from its housing, by pressing lever (A) of the rheostat in the
rest position the chip-blower is activated;
TURBINE MODULE
The turbine operates when the instrument is lifted from its housing and moved towards the operating field,
and when the foot control is engaged (see paragraph TURBINE OPERATION).
When the instrument is lifted from the table, all the other dynamic instruments and the patient chair
movements are disabled.
The spray is always pre-selected. The water delivered to the spray is regulated by opening/closing the tap
located near the instrument under the turbine module. When the tap is rotated clockwise, the flow of water to
the spray decreases until it stops; when turned anticlockwise, the opposite occurs. We recommend not using
other regulation devices located alongside the spray tap.
If the instrument is provided with optical fibre lighting, this can be activated by pressing the button
on the keypad.
Recommended air pressure (measured during turbine operations) is calibrated at O.M.S. factory inspection.
The calibration must be checked when installing the equipment using a gauge and observing the pressure
values indicated by the turbine manufacturer. This operation must be performed by an authorised O.M.S.
technician.
Note:
For further details refer to the manufacturer’s operating instructions enclosed.
ELECTRIC MICROMOTOR MODULE
The micromotor operates when the instrument is lifted from its housing and moved towards the operating
field, and when the foot control is engaged (see paragraph MICROMOTOR OPERATION).
With this movement, the micro-motor will rotate in a clockwise direction.
When the instrument is lifted from the table, all the other dynamic instruments and the patient chair
movements are disabled.
The micromotor enables work with a variable number of revolutions ranging from a minimum of 900 per
minute to a max. of 40,000 per minute, the Linea Patavium can be equipped with a proper low speed
pieceboard, which allows the micromotor to be run at 50 rpm.
