Relevant or helpful Information

12 Repair and Calibration Maintenance Manual
Frontline Sirius®
Warnings
The following statements are made to comply with the requirements of IEC 60601-1.
1. This equipment must only be connected to gas pipeline supply lines that are fitted with
pressure relief valves that limit the supply pressure to less than 7 bar.
2. The functioning of this machine may be adversely affected by the operation of equipment
such as high frequency surgical (diathermy) equipment, defibrillators or shortwave therapy
equipment in the vicinity. Increasing the distance from such equipment will minimise any
possible interference.
3. Prior to connecting the machine to a patient carry out the pre-use check to verify correct
alarm operation. To verify the O2 alarm, set the flowmeters to give a concentration of 50%
oxygen. Using the controls on the oxygen monitor panel, set the low oxygen level to 60%
and verify the oxygen low alarm operates. Set the high oxygen alarm level to 40% and
verify that the oxygen high alarm operates.
4. The oxygen flow can only be reduced to zero by turning the ON/OFF switch to the OFF
position. Excessive force on the oxygen control knob may damage the hypoxic guard.
5. To avoid explosion hazards, flammable anaesthetic agents such as ether and cyclopropane
must not be used in these machines. Only anaesthetic agents which comply with the
requirements on non-flammable anaesthetic agents in IEC 60601-2-13 ‘Specification for
Anaesthetic Machines’, are suitable for use in these machines.
6. As these machines are not suitable for use with flammable anaesthetic agents such as ether
and cyclopropane the use of antistatic breathing tubes and face masks is not necessary.
The use of antistatic or electrically conductive breathing tubes when utilising high frequency
surgery equipment may cause burns and is therefore not recommended in any application
that involves such apparatus.
7. The equipment must be periodically checked and maintained to ensure proper operation.
8. Performance of the equipment may be affected at temperatures below 10oC (50oF) and
above 40oC (104oF).
9. The performance of the anaesthetic machines and vaporizers may be degraded if the two
are mismatched. Refer to the vaporizer manufacturer’s instruction manual before use.
10. If the integrated oxygen analyser is not fitted, an oxygen analyser complying with ISO 7767
shall be used when the anaesthetic machine is in use.
11. The units use semiconductor devices which are susceptible to damage by overloading,
reversed polarity, electrostatic discharge and excessive heat or radiation. Avoid hazards
such as reversal of batteries, prolonged soldering, strong RF fields or other forms of
radiation, use of insulation testers or accidentally applied short circuits. Even the leakage
current from an unearthed soldering iron may cause trouble.

Electrostatic Sensitive Devices (ESD)
Warnings and Cautions
All ESD must be stored in approved conductive packaging, tubes, shipping bags, foam or tote
bins.
All persons handling ESD must be properly grounded via a 1MW resistive grounded wrist strap.
Cover all ESD bench tops with grounded conductive mats and connect all work surfaces and
equipment to earth ground.
Transport all assemblies containing ESD in a conductive bag or container.
DO NOT use cellophane adhesive tape to wrap DIP (dual in-line package) tubes together.
DO NOT handle ESD by their pins or mix them with other routine electronic parts.
Never place ESD on ungrounded surfaces or leave them unattended in an open area.
Avoid cellophane wrappers, synthetic (non-conductive) carpeting, warm or cool air blasts,
Styrofoam coffee cups, etc when working with ESD.
Use only properly designed heat lamps, heat chambers and/or ‘antistatic’ quick-chill sprays
during troubleshooting or stress testing procedures.
NB
In particular electronic assemblies in the Frontline Sirius®range of machines are easily damaged
by ESD and require special handling.
Cautions
Anaesthetic Machines
Do not leave gas cylinder valves open if the pipeline supply is in use and the system master
switch is turned ON. Pressures from both supplies may become equal and, if simultaneously
used, cylinder supplies could be depleted, leaving an insufficient reserve supply in case of
pipeline failure.
The hypoxic guard control system only ensures that oxygen-nitrous mixtures will have a
minimum oxygen concentration. HYPOXIC MIXTURES MAY BE DELIVERED IF GASES OTHER
THAN OXYGEN, NITROUS OXIDE OR AIR ARE USED, OR WHEN OPERATING AT LOW
OXYGEN FLOW RATES. When using carbon dioxide, as an additional gas, make sure the
proportions of all gases are carefully adjusted in accordance with accepted clinical practice. Gas
mixtures within the breathing system must be monitored when using these gases.

14 Repair and Calibration Maintenance Manual
Frontline Sirius®
Leaking gases and vapours (downstream of the flow control valves and Oxygen Flush valve)
may deprive the patient of metabolic gases and anaesthetic agent may pollute the atmosphere.
Tests that detect leaks must be performed frequently. If detected, leakage must be reduced to
an acceptable level.
Do not use the anaesthesia system if the hypoxic guard control system does not operate within
permitted ranges. Using an incorrectly operating control system may result in incorrect gas
mixtures and injury to the patient.
When occluding the breathing system for test purposes, do not use any object small enough to
slip completely into the system. Objects in the breathing system can interrupt or disrupt the
delivery of breathing system gases, possibly resulting in injury to the patient. Before using the
breathing system on a patient, always check the breathing system components for foreign
objects.
Do not place materials weighing more than 50kg on the bottom shelf, or more than 25kg on
the upper monitor shelf. Overloading may cause damage to the shelves or cause instability.
Secure any equipment placed on the shelves.
To avoid stripping threads, do not use tools on the yoke gate T screws. Use only one cylinder
gasket per yoke. Using more than one gasket could cause cylinder gas leakage.
Ventilator
The volume sensor must be correctly installed at either the distal location in the patient system’s
expiratory limb or the proximal end of the Y connector. If the sensor is installed incorrectly,
volume data will be inaccurate and associated alarms, including the low minute volume alarm
will not function properly.
Position the volume sensor’s cable with care. If the cable is pinched or cut, the ventilator’s
volume monitoring may not function correctly.
Do not connect the ventilator or absorber exhaust directly to a vacuum source. The vacuum
may remove required gases from the breathing system. (Only applies to Frontline Sirius 1000®
and 2000®).
Ventilator inoperative messages indicate that a problem exists in the ventilator. Do not attempt
to use the ventilator while a ventilator message is displayed.
Do not attempt to use the ventilator if the alarm mute button will not silence alarms.
WARNING: If an alarm condition cannot be resolved, do not continue to use the
system.
Sterilise the bellows assembly periodically to minimise the risk of cross infecting patients. Use a
sterilization schedule that complies with your institution’s infection control and risk
management policy. Only use Blease approved sterilization methods.
If any foreign materials or liquids are trapped in the driving gas circuit, or the pop off valve or
the bellows base they could impair the valve’s operation. Do not use the bellows assembly if

15Repair and Calibration Maintenance Manual
Frontline Sirius®
you suspect that materials are trapped. Have the assembly repaired by trained service
personnel.
Perform the Pre-Use Check procedures after cleaning and sterilizing the bellows.
Always perform the Pre-Use Check procedures for volume sensing functions after cleaning or
replacing the volume sensor.
Vaporizer
Do not use any vaporizer that is visibly misaligned on the manifold or that, when it is locked,
can be lifted off the manifold. Incorrect mounting may result in incorrect delivery of gases.
A vaporizer is calibrated and labelled for one agent only. Do not fill with anything other than
the designated agent.
If a vaporizer is filled with the wrong agent, draining will not eliminate the agent, because the
wick will have absorbed some of the agent. The wick must be thoroughly cleaned and dried by
trained service personnel.
The vaporizers must be completely upright for the sight glass to properly indicate agent levels.
Never oil or grease any oxygen equipment unless the lubricant used is made and approvedfor
this type of service. In general, oils and greases oxidise readily, and -in the presence of oxygen -
will burn violently. Fomblin is the recommended oxygen service lubricant (stock number
ST7014).
After performing any maintenance or repair procedure, always verify proper operation of the
system before returning to use.
Use cleaning solution sparingly. Do not saturate system components. Excessive solution can
damage internal devices.
Following ethylene oxide sterilization, quarantine the equipment in a well ventilated area to
allow dissipation of absorbed ethylene oxide gas. In some cases, aeration periods of seven days
or more may be required. Aeration time can be decreased when special aeration devices are
used. Follow the sterilizer manufacturer’s recommendations for aeration periods required.
