INSTALLATION

The PMA 30 is intended for stationary operation. In combination with a gas conditioning according to the
requirements a long-lasting operability and a minimum of maintenance is guaranteed.

The analyzer is designed for 19"-rack mounting. It has to be fixed at the 4 exterior holes in the front panel
with adequate screws.

CONNECTION OF SAMPLE GAS INLET AND SAMPLE GAS OUTLET

The sample gas inlet and outlet are placed at the back side of the analyzer and have a 1/8" NPT i thread. Screw
in here adequate tube connectors e.g. 1/8" NPT o – DN4/6 PVDF (Part No. 05V2045).

Connect the sample gas inlet with a corresponding gas conditioning with e.g. a PTFE hose DN4/6.

The sample gas must be dust free and dry to prevent a contamination
and condensation in the analyzer.
Basically, always connect a fine filter (e.g. type FP-2T, Part No. 01F1200)
upstream.
In case of outdoor operation protect the analyzer against sun, wind and
rain.
At the installation location constant climatic ambient conditions (pres-
sure, temperature) are necessary to prevent a distortion of the measure-
ment and a condensation in the measuring cell in case the ambient tem-
perature is falling below the dew point temperature of the sample gas.
A vibration-free location is ideal for mounting; if this is not possible, ap-
propriate measures must be taken. The analyzer must not be installed
in direct proximity of heat sources.
The position of operation is not necessarily horizontal.
The analyzer is allowed to be operated only in non-hazardous areas and
with non-ignitable gases and gas mixtures.
Leave enough space at the back side of the analyzer for unrestricted electrical
and pneumatic connections.
Sample gas has to discharge freely to atmosphere at the sample outlet because be-
cause an increase of pressure will distort the oxygen indication.
Do not bend the connection hoses.
