GAS 222.20 DH
2.2 General Hazard Warnings
The maximum surface temperatures of the probes also vary based on operating conditions (steam temperature, sample gas in-
let temperature, ambient temperature, fluid flow rate). When used in explosive areas, also particularly note the related hazard
warnings.
The equipment must be installed by a professional familiar with the safety requirements and risks.
Be sure to observe the safety regulations and generally applicable rules of technology relevant for the installation site. Prevent
malfunctions and avoid personal injuries and property damage.
The operator of the system must ensure:
– Safety notices and operating instructions are available and observed,
– The respective national accident prevention regulations are observed,
– The permissible data and operational conditions are maintained,
– Safety guards are used and mandatory maintenance is performed,
– Legal regulations are observed during disposal,
– compliance with national installation regulations.
Maintenance, Repair
Please note during maintenance and repairs:
– Repairs to the unit must be performed by Bühler authorised personnel.
– Only perform conversion-, maintenance or installation work described in these operating and installation instructions.
– Always use genuine spare parts.
– Do not install damaged or defective spare part. If necessary, visually inspect prior to installation to determine any obvious
damage to the spare parts.
Always observe the applicable safety and operating regulations in the respective country of use when performing any type of
maintenance.
NOTICE When used in explosive areas
The basic version of the probe is not suitable for use in Zone 1 or 21 explosive areas. The
accessories selected (e.g. add-on parts such as solenoid valves, heated blowback vessel...)
may severely limit the approved applications.
When using category 3G or 3D accessories, the are of application for the probe is limited
to Zone 2 or Zone 22. Therefore be sure to note the type plates for all add-on parts. Partic-
ularly pay attention to the ignition protection markings and all hazard warnings in this
manual.
DANGER Toxic, corrosive gas/condensate
Sample gas/condensate may be hazardous to health.
a) If necessary, ensure a safe gas/condensate discharge.
b) Always disconnect the gas supply when performing maintenance or repairs.
c) Protect yourself from toxic/corrosive gasses/condensate when performing mainten-
ance. Wear appropriate protective equipment.
DANGER Explosion hazard
Life and explosion risk may result from gas leakage due to improper use.
a) Use the devices only as described in this manual.
b) Regard the process conditions.
c) Check tubes and hoses for leakage.

GAS 222.20 DH
DANGER
Use in explosive areas
Flammable gasses and dust could ignite or explode. Avoid the following hazard sources:
Sparking!
Protect the equipment from external blows.
Flame propagation!
If the process holds a risk of flame propagation, install a flame arrestor.
Dust:
If possible, take the electrical components which must be opened for repair to a dust-
free room. If unable to do so, prevent dust from entering the housing.
Ignition of dust layers!
When using the device in a dusty environment, routinely clean dust from all compon-
ents. Also remove layers of dust in inaccessible areas.
DANGER Dangerous electrostatic charge (explosion hazard)
Incendive electrostatic charges may occur when cleaning plastic housing parts and
decals (e.g. with a dry cloth or compressed air). The sparks this produces could ignite
flammable, explosive atmospheres.
Always clean plastic housing parts and decals with a damp cloth!
DANGER Explosion hazard due to high liquid temperatures
Hot steam and hot sample gas cause in a high probe surface temperature. The highest
fluid temperature is approximately the maximum probe surface temperature.
a) Always ensure a safety clearance of at least 20 K between the fluid temperature
(steam, sample gas) and ignition temperature of explosive atmosphere (by measur-
ing and monitoring the temperature).
b) Also be sure to stay well below the smouldering temperatures of dust.
c) Observe the relevant requirements in standards regarding the max. permissible sur-
face temperature and ignition temperature of explosive atmosphere.

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 Installation
DANGER Danger to life and explosion during installation and maintenance
The unit must not be worked on (assembly, installation, maintenance) in explosive at-
mospheres.
DANGER Explosion hazard
When used in explosive areas
Flammable gasses and dust could ignite or explode.
Never operate the gas probe outside the specifications. Extracting gases or gas mixtures
which are also explosive in the absence of air is prohibited.
DANGER Explosion hazard due to ignition of dust
When using the device in a dusty environment, routinely clean dust from all compon-
ents.
The ignition temperature resp. smouldering temperature of flammable dusts resp. dust
layers present must be considerably higher than the maximum surface temperature of
the device (observe applicable standards and statutory regulations).
If possible, take the electrical components which must be opened for repair to a dust-
free room. If unable to do so, prevent dust from entering the housing.
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.
DANGER Dangerous electrostatic charge (explosion hazard)
Incendive electrostatic charges may occur when cleaning plastic housing parts and
decals (e.g. with a dry cloth or compressed air). The sparks this produces could ignite
flammable, explosive atmospheres.
Always clean plastic housing parts and decals with a damp cloth!
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 star-
tup.
Operating without downstream filter prohibited!
O-ring handle
Attach an O-ring suitable for the expected ambient temperature to the handle.
Attach the downstream filter 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 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.
