3.2 Warnings and Cautions
In the event the instrument covers are removed, observe the following warnings and cautions:
3.2.1 Warnings
WARNING: Whenever using anesthetic gases, nitrous oxide, oxygen, or
any hospital gas always follow the appropriate agent
evacuation/collection procedures. Use the hospital gas
evacuation system.
3.2.2 Cautions
CAUTION: This device uses high pressure compressed gas. When
attaching or disconnecting backup gas cylinders, always
turn the cylinder valves slowly. Use the AS3000 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.
CAUTION: 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 AS3000 gas
connection fittings.
3.3 Troubleshooting Guidelines
1. Identify the problem — Due to the wide variety of potential symptoms, certain
problems may be more subtle than others. Following the guidelines of the tests will help
determine the problem, if one exists.
2. Avoid shorting component leads together — During repair procedures, it can
be tempting to make a quick series of measurements. Always turn the power off before
connecting and disconnecting the test leads and probes. The accidental shorting of
leads can easily stress the components and cause a second failure (aside from the safety
risk).
3. Use the proper equipment — The equipment listed in “Special Tools Required” on
page 3-3, is suggested to fulfill a wide range of troubleshooting requirements. It is
imperative to use the designated equipment in order to ensure proper results of any and
all test procedures.
4. Clean up the repair area — After any repair, clean off the repair area.
