General Safety Notice / Residual Risk
If this equipment is used in a manner not specied in these instructions, protective systems may
be impaired.
Despite of incoming goods inspections, production control, routine tests and application of state-
of-the-art measuring and test methods, an element of risk remains when operating a gas analyzer!
Even when operated as intended and observing all applicable safety instructions, some residual
risks remain, including, but not limited to, the following:
• An interruption of the protective earth line, e.g. in an extension cable, may result in risk to
the user.
• Live parts are accessible when operating the instrument with doors open or covers removed.
• The emission of gases hazardous to health may even be possible when all gas connections
have been correctly made.
Avoid exposure to the dangers of these residual risks by taking particular care when installing,
operating, maintaining and servicing the analyzer.
