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 anitstatic 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.

2. 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.

3.1AM5000 AM5000/3 - AM5000/5 anaesthesia module
AM5000 - AM5000/3 – AM5000/5 regulates the supply and concentration of the gas mixture (Air, O2, N2O),
and also supplies it to the anaesthetic gas vaporizer.
It also allows the selection of the gas mixture to be supplied (Air-O2, or N2O-O2) and the enrichment (with
oxygen) of the supplied gas mixture for emergencies. The AM5000 - 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.
I OXYGEN supply gauge.
L NITROUS OXIDE supply gauge.
M AIR supply gauge.
N Selector switch for AIR / NITROUS OXIDE. This safety device:
avoids the contemporaneous supply of air and nitrous oxide
only the selected gas will be available on the flowmeters.
O OXYGEN BY-PASS key. By pressing this key pure oxygen is released into the anaesthesia circuit with a
flow of approximately 60 l/min.
P OXYGEN flow regulator for fresh gases. It opens counter-clockwise.
Q NITROUS OXIDE flow regulator for fresh gases. It opens counter-clockwise.

NOTE: THE HERE BELOW INDICATED SCHEMES AND THE PROCEDURES, HAVE BEEN UNIFIED
FOR THE THREE MODULES AM5000 – AM5000/3 – AM5000/5.
REMEMBER: DO NOT CONSIDER THE AIR LINE FOR ANAESTHESIA MODULE A 2 FLOWETERS.
Below is the pneumatic diagram which describes the unit:
The main purpose of the pneumatic distributor is to:
1. take the medical gases form the pipeline connections or cylinder connections.
2. monitor the operating pressure (pressure gauges)
3. select the type of mix that should be administered to the patient (gas selector AIR-N20)
4. take the selected gases to the flowmeter box
5. allow the mixed gases to be taken to the patient ventilation system (breathing system)
6. enrich the oxygen mixture in case of need (O2 bypass)
All the supply inlets are protected by a non-return valve, in order to avoid a leak of gas in case there is no
supply.
P.N.: DU5506130 Page 8 of 34 Rev.: 3.0
AM5000 – AM5000/3 – AM5000/5
Service Manual
As secondary functions, it allows:
supplies an auxiliary outlet of only oxygen which is automatically closed for connections to reanimation bags
for emergencies,
supplies auxiliary outlet for O2 and Air (Aux outlet Air/O2) for devices such as the lung ventilator, ventury
aspirator, etc...
The auxiliary outlets for Air/O2 supply medical air if it has a pressure higher than that of the oxygen minus
0.5 bar. The non-return valves 18 and 26 are necessary in order to avoid that air and O2 mix due to the
pressure difference between the two gases’ supply.
Each gas cylinder or pipeline supply conforms to the DISS standard in order to avoid mistakes in identifying
the gases.
The gauges have a colored band indicating the range at which there is the correct supply pressure.
The gases supplied to the AM5000 - AM5000/3-AM5000/5 are connected to the flowmeter box in order to
regulate the flows and to mix the gases that are then sent to the anaesthetic gas vaporizers. From these they
are taken back to the AM5000 - AM5000/3-AM5000/5 in to later be sent to the connector for the fresh gas
supply in the patient ventilation circuit. The gases mixed with the anaesthetic can be later mixed with pure
oxygen for enrichment of the mix that can be done by the operator by using the bypass button.
The selector enables using two different types of breathing systems without disconnection between the
tubes: the first is the patient circuit of the breathing system and the second, is the To and Fro, which is used
for manual ventilation of the patient’s breathing apparatus.
