Safety Instructions Part A
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.
"The drain of the condensate trap is a secondary source of gas release. In case of poor ventilation,
a hazardous explosive atmosphere may arise. Therefore please make absolutely sure to close the
discharge tap after emptying the condensate traps."
