3 Transport and storage
Only transport the product inside the original packaging or a
suitable alternative.
The equipment must be protected from moisture and heat
when not in use. They must be stored in a covered, dry and
dust-free room at a temperature between -20 °C to 50 °C (-4 °F
to 122 °F).

4 Installation and connection

4.1 Installation site requirements

Sample gas probes are intended for flange mounting.
• Installation site and installation position are determined
based on requirements specific to the application.
• If necessary, the connection piece should be slightly tilted
toward the centre of the channel.
• The installation site should be protected from the
weather.
• In addition, adequate and safe access for installation and
future maintenance work should be provided. Particularly
follow the uninstalled size of the probe tube!
If the probe is transported to the installation site in pieces, it
will first need to be assembled.
4.2 Installing the sampling tube (optional)
The sampling tube, if necessary with the fitting extension,
must be screwed in. The probe is then attached to the mating
flange using the included seal and nuts.
4.3 Installing the downstream filter (optional)
NOTICE
The downstream filter and the O-ring for the handle must be
inserted prior to first startup.
Operating without downstream filter prohibited!
O-ring handle
4.4 Installing the upstream filter (Optional)
The upstream filter, if necessary with matching extension,
must be screwed in. The probe is then attached to the mating
flange using the included seals and screws.

Attach an O-ring suit-
able for the expected
ambient temperature
to the handle.
Attach the down-
stream filter to the
handle. Then carefully
insert the handle with
filter in the gas probe
and turn 90° to se-
cure.
Verify the handle is
seated correctly. When
seated correctly it
locks onto the filter
housing.
4.5 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.
4.6 Connecting the Gas Line
The sample gas line must be carefully and properly connected
using a suitable fitting.

WARNING
Gas emanation
Sample gas can be harmful to the health!
Check the lines for leaks.
4.6.1 Blowback Connection
Without accessories installed for the blowback device, the
blowback connection comes with a sealed G3/8 screw-in con-
nection. If you require blowback, you will need to undo this
screw-in connection and ensure the blowback line is connec-
ted properly and tight.
DANGER
Toxic, corrosive gasses
Explosive or toxic gases can develop due to a leaking or open
blowback connection.
