GAS 222.35
DANGER

Potentially explosive atmosphere

Explosion hazard if used in hazardous areas.
The device is not suitable for operation in hazardous areas
with potentially explosive atmospheres.
Do not expose the device to combustible or explosive gas mix-
tures.
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 upstream filter
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.
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.

WARNING
Gas emanation
Sample gas can be harmful to the health!
Check the lines for leaks.
4.4.1 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.
