•
To avoid the connection of incompatible accessories to the unit, the insulation characteristics of the items to be replaced
must be requested to the manufacturer and compared to those of the supplied unit (see TECHNICAL
CHARACTERISTICS).
•
Attention:
a damage of the electrosurgical unit could result in an unwanted increase of the output power.
•
Inadvertent stimulation of a patient's muscle and nerves can be caused by low frequency currents originating in electric sparks between
electrode and tissue of the patient. Should neuromuscular stimulation occur stop surgery and check all connections to generator. If this
does not solve the problem, qualified service personnel must inspect generator.
•
Remember to not put on jewels, swatches or other metallic objects in the operative room.
5.2 INSTALLATION
•
The electric safety is insured only when the same are correctly connected to an efficient net linked to the earth in
conformity with the actual safety requirements. It is necessary to verify this fundamental safety requisite and, in case of
doubt, to require an accurate control of the plant from part of qualified personnel. The manufacturer cannot be considered
responsible for possible damages caused from the lack of efficient connection to earth of the installation. Operation
without a protective earth connection is forbidden.
•
Before connect the equipment ascertain that the required voltage (showed on the rear panel) corresponds to the available
mains.
•
In case of incompatibility between the available wall socket and the feeding cable of the equipment, replace only with
legally approved connectors and accessory items. The use of adapters, multiple connections or cable extensions is not
advised. Should their use become necessary it is mandatory to use only simple or multiple adapter conforming to the
actual safety requirements.
•
Don't let the apparatus exposed to atmospheric agents. The unit must be protected from seepage of liquids.
•
Don't obstruct openings or cracks of ventilation or heath sink
•
Don't leave the equipment uselessly inserted. Switch off the equipment when not in use.
•
The use of the unit is not suited in explosive rooms.

must be destined only to the use for that have been expressly designed.
Any other use is to be considered improper and dangerous. The manufacturer can not be considered responsible for
possible damages due to improper, wrong and unreasonable uses.
•
It is dangerous to modify or try modifying the characteristic of the equipment.
•
Before effect any operation of cleaning or maintenance, disconnect the apparatus from the electric net, either unplugging it
from the mains or switching off the mains switch of the plant.
•
In case failure and/or bad operation of equipment switch off it. For the possible reparation address only to an authorised
service centre and ask for the use of original spare parts. The lack to follow the above requirements could risk the safety of
the equipment and can be dangerous for the user.
•
Do not reduce or disable the audible signal warning the activation of the generator. A functioning activation signal can
minimise or prevent patient or staff injury in the event of accidental activation.
•
Avoid verifying the functioning of the unit by shorting the active electrode with the reference one or the active electrode
with metallic parts.
5.3 SAFETY FOR THE PATIENT
During the HF electrosurgical operations the patient is a conductor of electrical voltage against earth potential. So if there is a
contact between patient and electrical conductive objects (metal, wet clothes,etc..), in the contact’s point could be electrical
current that causes thermical necrosis. So it is recommended to inspect the equipment and its accessories before using and to
respect all safety rules.

P
OSITION OF THE
P
ATIENT
It is important to avoid any intention or accidental contact between patient and grounded metallic parts and to make sure that:
-
The patient is not in contact with metallic parts (operative table, supports..).
-
The flexible tube of the respirator do not touch the body of the patient.
-
On the operative table with grounded connection there are always coatings that allow to discharge the electrostatic
charges.
-
The patient is on a thick basic tissue with insulating properties, covered by a sufficient number of nets.
-
The patient is not in contact with nets or wet mattress.
-
The eventual organic secretions and the cleaning and other liquids do not wet the nets.
-
There are not liquid under the patient.
-
Urinary secretions are eliminate by the catheters.
-
The body zones characterized by an higher sweating, the extremities in direct contact with trunk or the points of skin-
skin contact are dried by the nets interposition (arm/trunk , leg/leg, breast, skin folds, etc.).
-
All conductive and grounded supports, stirrups, are correctly insulated.
-
Control the anaesthetics quantity to avoid an great sweating.
