– 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.
DANGER Electrical voltage
Electrocution hazard.
a) Disconnect the device from power supply.
b) Make sure that the equipment cannot be reconnected to mains unintentionally.
c) The device must be opened by trained staff only.
d) Regard correct mains voltage.
DANGER Toxic, corrosive gases
The measuring gas led through the equipment can be hazardous when breathing or
touching it.
a) Check tightness of the measuring system before putting it into operation.
b) Take care that harmful gases are exhausted to a save place.
c) Before maintenance turn off the gas supply and make sure that it cannot be turned
on unintentionally.
d) Protect yourself during maintenance against toxic / corrosive gases. Use suitable pro-
tective equipment.
DANGER Potentially explosive atmosphere
Explosion hazard if used in hazardous areas.
The device is not suitable for operation in hazardous areas with potentially explosive at-
mospheres.
Do not expose the device to combustible or explosive gas mixtures.

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.
7Bühler Technologies GmbHBE460062 ◦ 09/2021

GAS 222.35
4.4.1 Blowback Connection
Without accessories installed for the blowback device, the blowback connection comes with a sealed G3/8 screw-in connection. If
you require blowback, you will need to undo this screw-in connection and ensure the blowback line is connected properly and
tight.
DANGER Toxic, corrosive gasses
Explosive or toxic gases can develop due to a leaking or open blowback connection.
4.4.2 Connecting the Gas Line
Please note the following items when connecting the sample gas line (NPT 1/4") on heated probes to prevent thermal bridges:
– 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.
CAUTION Fragile
The insulation is fragile. Handle with care, do not drop.
After connecting the sample gas line it must be braced and secured 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.
WARNING Gas emanation
Sample gas can be harmful to the health!
Check the lines for leaks.
4.4.3 Connecting the calibrating gas line (optional)
Connecting the calibrating gas line requires a Ø6 mm or Ø1/4” pipe fitting.
If the calibrating gas connection was ordered with check valve, a Ø6 mm or Ø1/4” pipe can be connected directly to the check
valve.
4.5 Connecting the Blowback and Pressure Vessel (Optional)
The air lines must be connected carefully and properly, using suitable fittings.
If the probe is equipped with pressure vessel for efficient blowback (optional), a manual shut-off valve (ball valve) must be in-
stalled in the air supply, immediately upstream from the pressure vessel.
NOTICE
The operating pressure of the compressed air (inert gas) required for blowback must al-
ways be higher than the process pressure.
Required pressure differential min. 3 bar (44 psi).
DANGER Broken pressure vessel
Gas leak, danger due to flying parts.
Maximum operating pressure of the pressure vessel 10 bar (145 psi)!
The operating pressure reduces based on the operating voltage (see solenoid valve type
plate).
