A7™ Service Manual 046-006272-00 ix
Notes Introduction
CAUTION: 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.
CAUTION: Use cleaning agent sparingly. Excess fluid could enter the machine,
causing damage.
CAUTION: This machine must only be operated by trained, skilled medical staff.
CAUTION: 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.
CAUTION: After changing the CO2 absorbent, carry out a vaporizer and system
leak test.
CAUTION: Only Selectatec™ compatible vaporizers with Interlock-System may be
used with the A7 unit.
CAUTION: After each exchange of a vaporizer, carry out a system Leak test.
CAUTION: Do not clean the machine while it is on and/or plugged in.
CAUTION: Pressing "cancel" at any time during the procedure will cancel the
session's settings and reload the previously-stored calibration
coefficients.
CAUTION: Depleted sodalime changes color. Replace the sodalime if
approximately 2/3 of the absorber content is discolored. CO2 absorbent
can be safely changed without stopping mechanical ventilation.
CAUTION: This equipment contains parts sensitive to damage by electrostatic
discharge (ESD). Use ESD precautionary procedures when touching,
removing, or inserting parts or assemblies.
CAUTION: The watertrap collects water drops condensed in the sampling tube and
therefore prevents them from entering the AG module.If the collected
water reaches a certain amount, you should drain it to avoid airway
blockage.
CAUTION: The watertrap has a filter preventing bacterium,vapor and patient
secretions from entering the module.After a long-term use,dust or
other subtances may compromise the performance of the filter or even
block the airway.In the case, replace the watertrap.Replacing the
watertrap once a month is recommended.
CAUTION: Strong scavenging suction on the AG monitor exhaust port nay change
the operating presure of the monitor and cause inaccurate readings or
internal damage.
Notes
NOTE: Unauthorized servicing may void the remainder of the warranty. Check
with the factory or with a local authorized distributor to determine the
warranty status of a particular instrument.
