The sample gas arrives in the measuring cell
2
via the inlet fitting.
It is very important to protect the measuring cell
2
against liquid and dust particles. This is the reason
why the externally mounted upstream gas conditioning system must be equipped with a fine filter of at
least 2 micron porosity (e.g. type
FP-2T
).
The gas volume flow of 6 Nl/h up to 60 Nl/h is adjusted via an externally mounted flowmeter with nee-
dle valve.

RECEIPT OF GOODS
The analyzer
PMA 45K1
is a completely pre-installed unit.
•
Please take the analyzer and possible special accessories carefully out of the packaging material
immediately after arrival, and compare the goods with the items listed on the packing list;
•
Check the goods for any damage caused during delivery and, if necessary, notify your transport
insurance company without delay of any damage discovered.
NOTE!
The oxygen analyzer must be stored in a weather - protected and frost-
proof area !

INSTALLATION
The analyzer
PMA 45K1
is constructed for stationary wall mounting. All electrical connections are to
be found inside the analyzer housing.
The correct installation as well as an optimal sample gas conditioning unit mounted upstream – if nec-
essary with an appropriate gas sample probe – guarantee a long lasting functioning and a minimum of
maintenance.
CAUTION!
In case of outdoor operation, the analyzer must be protected
against sun, wind and rain.
At the installation location constant climatic ambient conditions
(pressure, temperature) are necessary to prevent a falsification of
the measurement due to changing barometric pressure. Further,
there is the risk of condensation in case the ambient temperature
falls below the dew point temperature of the sample gas in front of
the measuring cell.
A vibration-free location is ideal for mounting; if this is not possi-
ble, rubber-bonded metals (anti-vibration) have to be mounted in
order to decouple the housing. The analyzer must not be installed
in direct proximity of heat sources.
NOTE!
The sample gas must be dry and free of dust to avoid contamina-
tions and a falling below the dew point inside the analyzer. In prin-
ciple, a fine filter with a porosity of minimum 2 micron should be
installed upstream.
Counter pressure in the sample gas outlet should be avoided!
