Warning
It is essential that you observe the following information and instructions!
Hazardous voltages
Certain parts of this device are carrying hazardous voltages. Before the
unit is switched on, the housing must be closed and grounded.
Failure to comply may result in death, physical injury or damage to
property.
In this regard you should also read and comply with the section entitled
"Electrical connection" on page 3-5.
Poisoning hazard
When toxic or corrosive gases are being analyzed, the exhaust gases
must be taken off in such a way that persons present are not exposed to
any danger. Exhaust gas lines must be made of material which is
resistant to the sample (see also "Design of housing and FID" on page 2-
4).
Failure to comply may result in serious symptoms of poisoning or even
death.
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.
Combustion hazard
During operation the interior of the unit's oven reaches a temperature of
around 200°C. With the aid of function 2 not only the actual temperature
of the oven but also any other temperature setting may be accessed.
Once the unit has been switched off, temperatures fall only at a very slow
rate. This is why the oven is not accessible to operating personnel during
normal operation.
Protective gloves must always be worn during maintenance work. Note
too that hydrogen burns colorlessly. Failure to observe this may result in
serious burns.
Flushing the housing
In accordance with details in the technical data starting on page2-14,
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.
Note
However, this does not apply to toxic or corrosive gases! In this regard
the maximum allowable workplace concentration figures must be
observed.
