1.3 Cautions
CAUTION

This device uses high pressure compressed gas. When attaching or disconnecting
backup gas cylinders, always turn the cylinder valves slowly. Use the 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 gas connection fittings.

Refer to the 6.2Maintenance 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 A5 unit.

After each exchange of a vaporizer, carry out a system Leak test.

Do not clean the machine while it is on and/or plugged in.

Pressing “cancel” at any time during the procedure will cancel the session's
settings and reload the previously-stored calibration coefficients.

Depleted soda lime changes color. Replace the soda lime if approximately 2/3 of the
absorber content is discolored. CO2 absorbent can be safely changed without
stopping mechanical ventilation.

This equipment contains parts which are easily damaged due to electrostatic
discharge (ESD). Follow ESD prevention program when touching, taking out, or
inserting parts or components.
