GAS 222.11 Ex1
DANGER
Explosion hazard due to flame propagation
Severe injuries and damage to the system
If the process holds a risk of flame propagation, install a
flame arrestor.
4.3 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.
4.4 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!
O-ring handle
4.5 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.

4.6 Connecting the Gas Line
The sample gas line must be carefully and properly connected
using a suitable fitting.

Please note the following items when connecting the sample
gas line (NPT 1/4") 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.

• 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.
