WARNING
Improper device modifications
Risk to personnel, system and environment can result from modifications to the device, particularly in hazardous areas.
Only carry out modifications that are described in the instructions for the device. Failure to observe this requirement
•
cancels the manufacturer's warranty and the product approvals.
NOTICE
Manipulation of the device
Physical access to the device enables undesired manipulations of the device. As a result of this, the device can lose its
measuring properties and become unusable.
Ensure that the device is located in a protected area to which only authorized persons have access.
•
If no settings need be carried out, lock the device.

WARNING
Harmful gases
Danger to personnel, system and the environment can result from introducing harmful (corrosive, flammable and/or
poisonous) gases into the device. If this should be required for the measuring task of the device, you must take the
following measures:
Take into account the safety measures according to the German Occupational Safety Act (Arbeitsschutzgesetz -
•
ArbSchG) or similar international regulations. These safety measures must be coordinated with a local specialist. In
particular, this includes measures to prevent any potential release of gases from the internal gas path (containment
system) as well as their monitoring and disposal.
Ensure that the discharged gas is treated according to the applicable local laws.
•
When you measure gases with flammable components at concentrations above the lower explosion limit (LEL), we
•
recommend that you only use piped devices (see also report BB-EG1-KAR Gr02X from TÜV Süddeutschland).
Purge the device or the plant with a purging gas (inert gas). The gas displaced by purging must be collected using
•
appropriate equipment and disposed of environmentally-friendly via an exhaust line.
WARNING
Harmful substances in the condensate
The condensate at the sample gas cooler or condensation trap can be corrosive, depending on the composition of the
sample gas (e.g.: through SO
Wear protective clothing, protective goggles and protective gloves when handling the condensate!
•
Prior to its disposal, dilute the condensate with tap water until it turns neutral and the litmus paper does not change
•
color. Alternatively, you can also neutralize the condensate with a weak sodium carbonate solution (Na
6
, NO, H S, HCl, etc.). When you dip litmus paper into the condensate it will turn red.
