WARNING
Harmful gases
Danger to personnel, system and the environment can result from introducing harmful
(corrosive, 󹪞ammable 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 national laws. 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.
• Purge the device or the plant with a purging 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
2
, NO, H
2
S, HCl, etc.). When you dip litmus
paper into the condensate it will turn red.
• 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
2
CO
3
).
WARNING
Risk of explosion due to improper use
A device in the standard version must never be used in hazardous areas.
Observe the safety rules, provisions and laws applicable in your country during connection,
assembly and operation. These include, for example:
• National Electrical Code (NEC - NFPA 70) (USA)
• Canadian Electrical Code (CEC Part I) (Canada)
Further provisions for hazardous area applications are for example:
• IEC60079-14 (international)
• EN60079-14 (EU and UK)
