ROUTINE MAINTENANCE
The
analyser must be maintained by a suitable skilled and competent person.
Sample and calibra�on gases may be toxic, asphyxiant or flammable. Never inspect
the inlet filter, open the front cover of the sample/control compartment, or service or
repair the
analyser while such gases are s�ll connected to it.
Sample and calibra�on gases may be toxic, asphyxiant or flammable and hazardous
concentra�ons may accumulate within the analyser
during use. Always o
pen the
front cover of the sample/control compartment in a force
-
ven�lated enclosure with a
minimum volume of 17 m3, o
r in another
appropriate environment, in which any
hazardous gases are directed away from you.
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 par�culates into the breather vent or the interior of the analyser
.
8.2
Inspection
It
is recommended that the analyser is inspected for signs of corrosion. Par�cular care is should be taken
when inspec�ng the door seals, sample inlet and outlet entries, moun�ng plate and the gland entries.
If a sample system or corrosive purge is being used, then the opera�on of these should be verified at
regular intervals, no greater than annually. Failure of either the sample system or the corrosive purge
can result in significant analyser damage and research has shown that sample system failures account
for over 70% of analy�cal measurement field failures.
The pressure drop across the analyser is low, less than 1.0kPa (0.15psi) in most cases, if excessive
pressure is required to generate a flow through the analyser it is an indica�on that the inlet sintered
filter is blocked or contaminated. If this is the case, then this fi�ng can be removed and inspected or
replaced.
8.3
Inspecting/replacing the fuse (when necessary)
E
nsure 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.
Do not remove the cover of the power/signal compartment if an explosive
atmosphere may be
present.
The power/interface compartment cover is heavy. Ensure that you do not drop the
cover once it is disengaged
from the body of the analyser. If you do, you may injure
