14 RECEIPT OF GOODS
The analyser PMA 50 Ex is a completely pre-installed unit.

Please take the analyser and possible special accessories carefully out of the packaging mat e-
rial 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 tran s-
port insurance company without delay of any damage discovered.
N O T E !
The oxygen analyser PMA 50 Ex must be stored in a wheather - pro-
tected and frost-proof area !
15 INSTALLATION
The analyser PMA 50 Ex is designed for stationary wall mounting. All electrical connections are
located inside the connecting box below the analyser housing.
Accurate and proper installation as well as a preceding optimal sample gas conditioning system
will result in a long operatability and a minimum maintenance.
When using the analyser outdoors, it must be protected against atmospheric influences.
The installation should be done in constant climatic ambient conditions if possible.
The ideal installation site should be free from vibration. If this is not possible, rubber -metal con-
nections must be mounted in order to decouple the housing.
The analyser must not be installed in direct proximity of heat sources.
W A R N I N G !
The sample gas must be dry (dew point 5°C), free from dust and the
sample gas temperature is not allowed to exceed 50°C. Otherwise
an upstream sample gas cooler with automatic condensate removal
is necessary.
A preceding fine filter of at least 2 micron is absolutely necessary.
The sample gas has to flow off atmospherical freely at the sam-
ple gas outlet, because a pressure rise at the sample gas outlet
and therefore in the measuring cell falsifies the oxygen indica-
tion.
The maximum inlet pressure is 1,1 bar abs. For the standard device
and 1,5 bar abs. for devices with purging enclosure or ventilation.
