A5/A3â„¢ Operating Instructions 046-003777-00 xv
Cautions Introduction
CAUTION: Before clinical use, the machine must be correctly calibrated and/or the
respective tests must be performed, as described in these Operating
Instructions.
CAUTION: If system faults occur during the initial calibration or testing, the
machine should not be operated until those faults have been corrected
by a qualified service person.
CAUTION: After servicing, functional, sensor, and system tests must be performed
before clinical use.
CAUTION: Only vaporizers with Selectatec Interlock-Systems may be used with
the A5/A3 unit.
CAUTION: After each exchange of a vaporizer, perform a vaporizer leak test.
CAUTION: Use cleaning agent sparingly. Excess fluid could enter the machine,
causing damage.
CAUTION: Do not autoclave any parts of the A5/A3 unless specifically identified as
autoclavable in this manual. Clean the A5/A3 only as specified in this
manual.
CAUTION: To prevent system damage:
• Refer to the literature supplied by the manufacturer of the
cleaning agent.
• Never use organic, halogenated or petroleum-based solvents,
anesthetics, glass cleaning agents, acetone or other irritant
agents.
• Never use abrasive agents (i.e. steel wool or silver polish) to clean
components.
• Keep all liquids away from electronic components.
• Prevent liquid from entering the equipment.
• All cleaning solutions used must have a pH between 7.0 and 10.5.
CAUTION: Never immerse the oxygen sensor or its connector in any type of liquid.
• Dispose of the oxygen sensor as per the local regulations.
CAUTION: Do not use acetic hydroperoxide or formaldehyde steaming.
CAUTION: The valve disc in each of the inhalation and exhalation valve assemblies
on the breathing system is fragile and must be handled with care while
removing the valve cage from the valve assembly.
CAUTION: If moisture remains in the bellows after cleaning, the bellows surface
folds may become tacky and prevent the bellows from properly
expanding. Ensure all moisture is removed from the bellows after
cleaning.
CAUTION: Only connect Mindray approved equipment to the A5/A3
communication ports. Equipment connected to the A5/A3 ethernet
ports must comply with IEC 60950.
CAUTION: Do not connect any non-isolated devices to the DB9/RS232C interface
of the A5/A3.
CAUTION: Do not connect any devices to the SB ports other than Mindray
approved USB storage devices and a supported USB mouse (see
‘‘Networking and USB Storage’’ on page A-4).
