Warnings and Cautions
22. The use of antistatic or electrically c ondu c t i v e
breathing hoses is not
recommended when u s i ng
high frequency electrical surgery equipment ( e. g .
Diathermy). Burns may be
caused.
23. To avoid the risk of electric shock, this equipment must
only be connected to a mains supply with a protective
earth.
Before any
electrically powered machine is u s e d
clinically for the first time, check that t h e hospital
engineering
department has carried out an earth
continuity t e s t .
24. Portable RF communcatons equpment (ncludng
perpherals such as antenna cables and external
antennas) should be used no closer than 30 cm (12
nches) to any part of ths devce, ncludng cables

missing or defective protective earth c ondu c t o r
may increase earth leakage currents to t h e patient
to values exceeding the allowable
li m i t s , resulting
in ventricular fibrillation, or interference with the
pumping action of the
h ea r t .
27. Additional equipment placed on the top s h e l f must be
securely a
tt a c h e d . See also Warnings 1 and 3.
Take care when moving a fully loaded
m a c h i n e,
particularly when negotiating r a m p s .
Check that hoses or power leads are not
t r a ili ng on
the
f l oo r .
28. Accessories must be removed before t h e machine is
t r a n s po r t e d .
29. To prevent patient injury in the event of
t o t a l
anaesthesia system failure, an alternative m ea n s of
ventilation must be available whenever t h e device is
in
u s e.

1. Flowmeter needle valves are designed to seal with light
torque and may be damaged if tightened excessively.
Do not force the control knob past either the fully open
or fully closed positions.
2. Open cylinder valves slowly to avoid damage to pressure
reducing valves.
Ensure that cylinder valves are at least one full turn
open when in use.
3. Under no circumstances should anaesthetic agents be
used for cleaning purposes.
4. After use, always disconnect the machine from the piped
gas supply and/or close the gas cylinder valves.
5. Mechanical AHD system:
a) The oxygen flow control is restricted to prevent
the needle valve from fully closing. This ensures a
minimum basal flow of oxygen.
b) DO NOT attempt to close the flow to zero.
Do not overtighten.
6. Compressed gas supplies must be clean and dry.
7. When the auxiliary gas outlets are in use on a machine
with cylinder supply only, or if the pipeline supply is not
in use, check flow rate requirements, and ensure that
adequate back-up cylinders are available.
8. The requirements of IEC 60601-1-1 apply to any device
connected to the auxiliary sockets. Users must be
aware of the risks of increased leakage currents when
equipment is connected to the auxiliary power sockets
9. In the event of malfunction of any device powered by
the auxiliary sockets, check if the circuit breaker has
tripped.
10. On machines with pipeline connections, note that a
malfunction of the central gas supply within your facility
may cause immediate cessation of gas delivery and total
anaesthesia system failure.
11. Do not apply excessive pressure to the display screen.
12. Vaporizers: Read the instruction manual supplied with
the vaporizer before clinical use.
13. Use a gauss meter to measure the magnetic field when
the system is positioned for use in the MR facility. Refer
to section 5.11.2 when using a Prima 451 with an AV-S
MRI Ventilator.
14. Switch the gauss meter OFF before any clinical
procedures are started in the MR facility.
15. Remove the gauss meter from the MR facility before
changing the batteries
