If the probe is transported to the installation site in pieces, it
will first need to be assembled.
4.2 Installation
Sampling tube 03 (sintered stainless steel filter) only needs to
be screwed on.
Sampling tubes 10 and 11 need to be screwed in, then covered
with filter paper and secured on the flange end with the
clamp.
The pressure vessel has two fittings with G ¼" internal thread
on the outside. One of these fittings is needed to discharge
condensate and must point downward. The other can be used
to connect a pressure gauge (not included). Unused fittings
must be sealed with a plug.
The pressure vessel can be turned to allow any mounting posi-
tion of the probe. To do so, unscrew the plug for from the air
connection at the back (drawing see data sheet). You will now
see the hex nut inside the opening. Loosen this, pull the pres-
sure vessel away from the probe and turn it in the desired dir-
ection. Ensure one fitting on the outside points downwards to
discharge condensate. Now tighten the nut again and screw
in the plug until tight.
The probe is then attached to the mating flange using the in-
cluded seals and screws.
4.3 Insulation
On heated probes completely insulate any exposed flange
areas and, if applicable, the connection piece to absolutely
prevent thermal bridges. The insulating material must meet
the application requirements and be weatherproof.
4.4 Connecting the Gas Line
The sample gas line must be carefully and properly connected
using a suitable fitting (NPT ¼"). This also applies to the test
gas connection. If the latter is not being used, seal it with a
plug.
To avoid condensation in the line in your application, it will
need to be heated. The screw-in connection and the probe
must then be insulated.
WARNING
Gas emanation
Sample gas can be harmful to the health!
Check the lines for leaks.

4.5 Electrical connections

WARNING
Hazardous electrical voltage
The device must be installed by trained staff only.
CAUTION
Wrong mains voltage
Wrong mains voltage may damage the device.
Regard the correct mains voltage as given on the type plate.

Electric strength test
The necessary tests of all assemblies required to be tested
were carried out at the factory (test voltage 1 kV or 1.5 kV de-
pending on component).
To check the electric strength again yourself, only do so on the
respective individual components.
• Now perform the electric strength test against earth.

4.5.1 Plug Connection

This device has an EN 175301-803 plug. The following pin as-
signments and the assignment of solenoid valves to the func-
tion are listed below. The numbers specified correspond with
those on the plugs.
The power supply is 24 VDC.
