anaesthetic gases such as ether of ciclopropane. This unit can operate only with anesthetics that are not
flammable as per the directive relative to the electrical safety of the anaesthesia units.
!
Do not connect the unit to the patient using conductive antistatic tubes.
Due to the fact that this machine cannot be used with flammable anaesthetic agents, such as ether or
ciclopropane, the use of antistatic patient tubes is not necessary. Since the use of antistatic tubes can cause
burns when using surgical equipment at high frequencies, their use is not allowed in any administration with
this equipment.
!
The unit is not approved for use in areas with danger of explosion.
The unit cannot be used in the presence of explosive gases.
Before connecting the unit with other electrical equipment not described in this manual,
check with the manufacturer.
The electrical connection of the unit should be made according to the instructions in this
manual in order to eliminate the danger of electric shock to the patient or operator due to an
improper installation.
Regarding electro-medical equipment’s general safety, it is important to follow all rules regarding the
interaction between the equipment and the patient, the operator and the nearby environment.

and the User’s manual and pay attention to the notes furnished in this User’s manual.
In order to use this equipment, it is vital to know all the instructions in this manual.
The equipment should be inspected and the maintenance performed by SIARE authorized personnel every 6
(six) months. All maintenance performed by SIARE authorized personnel is recorded in the equipment’s
maintenance log.
Every repair should be performed by SIARE authorized personnel. Siare is not liable for direct or indirect
damage to people or things, due to technical assistance by personnel non-authorized by SIARE or improper
use of the equipment, that is to say a use not described in the User’s manual or technical manual.
In order to repair equipment that is malfunctioning, has defects or is broken, the operator should contact
SIARE or its authorized local service dealer. It is important, when requesting service, to specify the model
and serial number of the equipment.
Use only the recommended accessories.
The use of other accessories is authorized only by a written authorization from SIARE as per the safety
directives in effect.
The equipment’s operation is authorized only in areas that conform to the safety directives in effect.

2. GENERAL MAINTENANCE PROCEDURES
2.1. General Information
!
In order to ensure the safety of the patient and the operator, the unit should undergo an inspection and test
after 800 hours of use or every 6 months, whichever comes first. The inspection and test require a specific
knowledge of the unit, and therefore have to be made by specially trained SIARE authorized personnel.
The anesthetist or doctor is responsible for the ordinary maintenance of the unit, as described in this chapter.
Cleaning, disinfecting, sterilization and replacement of parts should be done as per the instructions in the
user’s manual in order to avoid damage to the equipment that could also endanger the safety of the patient
and operator.
The components used have been selected after technical and comparative tests in the designing phase of
the machine.
Furthermore, the same components are always tested during the manufacturing cycle in order to obtain the
maximum level of safety and reliability for the operator and patient.
Therefore whenever a part needs to be replaced, it must be an original spare part, which has been checked
and tested by SIARE.
SIARE assumes responsibility for all provisions of the law, if the unit is used and maintained as per the
instructions in this manual and the technical manual. The Technical Assistance Report, signed by the
authorized SIARE technician, is proof of the completion of the scheduled maintenance.

3.3 AM5000/3 – AM5000/5 anaesthesia module
AM5000/3 – AM5000/5 regulates the supply and concentration of the gas mixture (Air, O
supplies it to the anaesthetic gas vaporizer.
It also allows the selection of the gas mixture to be supplied (Air-O
oxygen) of the supplied gas mixture for emergencies. The AM5000/3 – AM5000/5 is also equipped with the
MIX-LIFE device that guarantees a minimum of 25% oxygen in all open-tap conditions.
By using the three gauges located on the front panel, the medical gases supply pressure coming from the
central gas installation can be continuously controlled (precision ± 10%).
The flowmeters permit the measurement of the flow the of the corresponding gases with a precision of ±
10% of the displayed value or ± 1% of the bottom of the scale, by choosing the highest of the two values.

3.4 Breathing System
3.4.1. OPEN-SEMICLOSED VERSION (NON REBREATHING -REBREATHING)
It is the device that takes fresh gases towards the patient and that collects the expired gases towards the
CO
absorber and then to the lung ventilator to be supplied to the patient. The fresh gases supplied by the

AM5000 anaesthesia module are also added to the Breathing System.. With this cirucit it is also possible, by
simply rotating the selector (V), to change the system into an OPEN or NON-REBREATHING. The manual
ventilation is possible directly from the valve group or with the TO AND FRO system.
