GAS 222.20-HT, GAS 222.20-HT-OW-OR
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
NOTICE
The downstream filter and the O-ring for the handle must be
inserted prior to first startup.
Operating without downstream filter prohibited!

4.4 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.

4.5 Connecting the gas lines
4.5.1 Connecting the Gas Line
The sample gas line must be carefully and properly connected
using a suitable fitting. This also applies to the test gas con-
nection. If the latter is not being used, seal it with a plug.
Please note the following points on connecting the sample
gas line (Ø6 mm) on heated probes to prevent thermal
bridges:
Fragile
The insulation is fragile. Handle with care, do not drop.
After connecting the sample gas line it must be braced and se-
cured with the clamp.
Long sample gas lines may require additional support clamps
along the way to the analysis system! Once all lines have been
connected and checked for leaks, carefully reinstall and secure
the insulation.
Gas emanation
Sample gas can be harmful to the health!
Check the lines for leaks.
4.5.2 Connecting the calibrating gas line (optional)
Connecting the calibrating gas line requires a Ø6 mm or Ø1/4"
pipe fitting.

Damage to the device in case of insulation testing
Do not proceed insulation tests with high voltage to the

• Choose the shortest possible screw connection.
• Shorten the connection pipe for the sample gas line as
much as possible. To do so, remove the insulation around
the sample gas line. This is done by loosening the fixing
bolts.
