CAUTION

Use caution when disconnecting [quick connectors], as the sudden release of
pressure may cause injury.
 Avoid factors that can contribute to deterioration of the hose assemblies. Factors
include excessive bending, crushing, abrasion, system pressures and temperatures
that exceed hose ratings, and improper installation.
 Be careful in lifting and manipulating the breathing system during disassembly of
the system.
 When the electronic flow control system is disabled, the backup flow control
system will be enabled. The initial flow of backup flow control system is 1 L/min of
O2. The backup flow control system display only has a total flowmeter which can
display a maximum flow of 15 L/min.
 Turn the flow control knob of the backup flow control system slowly. To avoid
damaging the control valves, do not turn further when the flowmeter reading is out
of range. When turning a flow control knob clockwise to decrease flow, the
flowmeter should reach 1 L/min before the knob reaches its most clockwise
mechanical stop (off) position.
 Do not turn any further when the knob has reached the off position. Turning a
flow control knob counter clockwise increases flow.
 Prevent or avoid using and storing the gas supply hose assembly in an environment
exposed to ultraviolet light or oxidizing agents, or in a high-temperature or moist
environment to avoid damage to people and materials because of the release of
pressure from aged hoses in the assembly.
 This device uses high pressure compressed gas. When attaching or disconnecting
backup gas cylinders, always turn the cylinder valves slowly. Use the A8/A9 flow
meters to bleed down the pressure, watching the cylinder gauge indicate the
depleting cylinder pressure, before disconnecting the cylinder from the yoke.
Always open and close cylinder valves fully.
 This device operates using compressed gas at high pressures from the hospital
central supply. When connecting gas supply lines attach the hose connection to the
machine before connecting the quick disconnect fitting to the hospital source.
Disconnect the supply hose from the hospital source connection prior to
disconnecting it from the A8/A9 gas connection fittings.
 Refer to Section 4.2 Maintenance Period for assistance when performing scheduled
periodic maintenance.
 Do not leave gas cylinder valves open if the pipeline supply is in use and the system
master switch is turned to 'ON'. If used simultaneously, cylinder supplies could be
depleted, leaving an insufficient reserve supply in the event of pipeline failure.
 Use cleaning agent sparingly. Excess fluid could enter the machine, causing
damage.
 This machine must only be operated by trained, skilled medical staff.
 Perform the electrical safety inspection as the last step after completing a repair or
after routine maintenance. Perform this inspection with all covers, panels, and
screws installed.
 After changing the CO2 absorbent, carry out a system leak test.
 Only Selectatec™ compatible vaporizers with Interlock-System may be used with
the A8 unit
