MultiExact Gas Analyser

ROUTINE MAINTENANCE
WARNING
The analyser must be maintained by a suitably
skilled and competent person.
WARNING
Do not open or attempt to open the analyser yourself. If you do, you
will invalidate any warranty on the analyser, and the analyser may not
operate safely or provide accurate measurements.
WARNING
Sample and calibration gases may be toxic or asphyxiant:
•
Never inspect the inlet filter(s), or service or repair the analyser
while such gases are still connected to it.
•
If the analyser is to be serviced or repaired it is important that all
pipework is flushed with an inert gas and the analyser is allowed
to freely vent to local atmosphere.
CAUTION
If the analyser is to be temporarily removed, and it is measuring trace CO
2
,
the pipework should be purged with nitrogen and then the inlet and outlet
should be capped off. This is to prevent exhausting the CO
2
scrubber.
8.1
Cleaning the analyser
When necessary, use a damp (but not wet) cloth to wipe clean the outer surfaces of
the analyser (to prevent the entry of dust or other particulates into the interior of the
analyser).
8.2
Inspecting/replacing the fuse (when necessary)
WARNING
Ensure that the electrical supply is isolated/locked out
from the analyser. If you do not, there will be a danger of
injury or death from electric shock.
WARNING
Fire Hazard, only use the same type and
rated fuse as recommended.
