GAS 222.15-MA
NOTICE
Accessories may limit critical operating parameters of
the base unit
Adding accessories may limit critical operating parameters.
Ambient temperatures, zone classifications, explosion
groups, temperature classes or chemical resistances of ac-
cessories may vary from the base unit.
Always include all technical data in the operating instructions
and data sheets of all components in the safety assessment.
WARNING
Risk of breakage
a) Protect the equipment against being hit.
b) Protect the device against falling objects.
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

CAUTION
Equipment damage
Protect the device from falling objects as well as external
blows.
Lightning
On principle, the operator must meet all applicable standards
with respect to preventing damage to the equipment due to
lightning, which could result in equipment damage.
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.
• 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 has three sections and must be screwed in.
Proceed as follows:
• Screw the tube all the way into the fitting on the probe.
• Tighten the swivel nut well. Ensure the 2 mm wide at-
tached sealing face of the swivel nut faces the fitting.
• Also tighten the slim locking nut.
• Then attach the probe to the mating flange using the in-
cluded 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!
O-ring handle
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 Installing a heated sample gas line
To install a heated sample gas line:
• Remove the pipe clamp and insulating sleeve by loosen-
ing the M8x10 screw and removing the sleeve from the in-
sulation.
• Install a suitable pipe fitting in the probe body. Slip the
insulating sleeve over the sample gas line and connect to
the pipe fitting inside the probe body.
• Reinsert the insulating sleeve in the insulation, turning (a
drop of lubricant safe for silicone may help) and tighten
the worm drive hose clip. This ensures the connection
between the insulating sleeve and the sample gas line is
water- and dustproof. The factory installed insulating
sleeve is suitable for use with a heated line for outside
diameters of 47 – 53 mm. Insulating sleeves for other line
diameters are available on request.
• Lastly, reinstall the pipe clamp and attach the sample gas
line to it accordingly. Long sample gas lines may require
additional support clamps along the way to the analysis
system!
Attach an O-ring suitable
for the expected ambient
temperature to the handle.
Attach the downstream fil-
ter to the handle. Then
carefully insert the handle
with filter in the gas probe
and turn 90° to secure.
Verify the handle is seated
correctly. When seated cor-
rectly it locks onto the filter
housing.
