Warning
It is essential that you observe the following information and instructions!
Explosion hazard!
Use of the FIDAMAT 6 gas analyzer for measuring operationally explosive
mixtures is not permitted. If the unit is to be used for measuring flammable
gases which in combination with air or oxygen could form an explosive
mixture, special explosion-protection measures will need to be taken.
Electrical safety
Certain parts of this device are carrying hazardous voltages. Before the
FIDAMAT 6 is switched on, the housing must be closed and grounded.
Failure to comply may result in death, physical injury or damage to
property. For this, please also note "
Flushing the housing
In accordance with details in the technical data, there may be what is to
be regarded as a limited escape of flammable components from leaks in
the sample path. With the FIDAMAT 6 there is no need to flush the
housing provided it has been ensured that there is a natural exchange of
air from the environment. Your attention is particularly drawn to this in the
case where the analyzer is installed in a cabinet.
Warning
However, this does not apply to toxic or corrosive gases! When working
with corrosive or toxic gases the device must be flushed
