Preparing the Gas Analysis System for Use
DANGER
The device measures/rinses alternately with measuring gas and ambient air.
Combustible gas could enter the device through the exhaust gas line. This creates an explosion
hazard. Therefore, lead the exhaust gas lines separately to the outside and have nothing discharge
into the exhaust gas line.
You may only lead exhaust gas into gas-bearing areas (additional valve which only opens the path to
the point of discharge during operation of the gas pump) if the exhaust gas line is not longer than
20 m and a maximum underpressure or overpressure of 20 mbar prevails in the gas-bearing area.
When introducing exhaust gas into gas-bearing lines, the possibility of the formation of an explosive
atmosphere due to admixed air must be taken into account. Either feed into an Ex-Zone 1 or into an
area where the gas flows continuously.
