Safety Instructions Part A
Hydrogen sulphide is toxic. Watch out for smell of rotten eggs. Ventilate the room and do not
enter.
Carbon monoxide is toxic. A suitable gas warning sensor must be used, unless the ventilation is
sufficient.
The main switch serves as a mains disconnection facility to shut down the function and avoid
hazards caused by electricity. The device has to be installed in such a way that the main switch
operation is not impeded.
In case of a defect, gas leakage may occur. In case of insufficient ventilation, even small amounts
can lead to a hazard (poisoning, explosion) over a longer period of time. The device must
therefore not be installed in unvented shafts or poorly ventilated rooms.
Different electrical voltages may be present at the terminals in the terminal box. An incorrect
connection will lead to malfunction and hazards arising from electrical current. For information
on the allocation of the different terminals or the wiring in the terminal box please refer to the
electric diagram provided as part of the system.
Combustible gas could enter the device through the exhaust gas line and create an explosive
atmosphere there. Therefore, lead the exhaust lines separately and directly to the outside and
have nothing discharge into the exhaust gas line. In case of analysis gas recovery, ensure the
exhaust gas line is not longer than 20 m and have it lead the exhaust gas only into gas-bearing
areas in which a maximum underpressure or overpressure of 20 mbar prevails.
Gas which may be toxic, flammable or explosive flows through the exhaust gas line. Therefore,
the exhaust gas must not be released inside the building unless there is appropriately sufficient
ventilation.
The device conveys combustible gas. A continuous stay in the immediate vicinity of the device
may lead to a statistically increased risk of explosion. Therefore, no persons are allowed to stay
permanently in the vicinity of the device.
To ensure the safe and correct operation of the process analysis system, regular maintenance
work is an absolute necessity, as during this process wearing parts (such as seals) are replaced
and the whole system is checked thoroughly. Failure to comply increases the risk by gas leakage
(danger of explosion). The maintenance interval must therefore be observed.
The state of the gas analysis system must be checked on a regular basis, error messages need to
be addressed. In the event of the error messages "potentially dangerous atmosphere" or "risk of
explosion" as well as with loose hose ends, porous hoses or other leaks that lead to an explosion
hazard, disconnect the device from the gas supply and shut it down. Contact Awite or an Awite
contract partner.
