2.2. Notes on the use of nitrogen
Nitrogen is not a toxic gas, but when the percentage in the air exceeds specific
values there is a risk of asphyxia.
Therefore NEVER DIRECTLY INHALE the gas produced and avoid working in the
vicinity of a flow of nitrogen.
However, given the low quantities produced, it is sufficient that the flow of ni-
trogen occurs in a nor ally ventilated environ ent to avoid the risk of accu u-
lation.
m If the generator and the user utility are located in different rooms, the
following minimum ventilation must be provided to prevent increasing
or decreasing the oxygen content in the air:
2.3. Safety devices
MAXIMUM PRESSURE: the control syste constantly onitors the pressure.
In case of ano alous pressure, a safety valve (which operates independently of
the control syste ) prevents it exceeding 10.5 bar (152 psi).
MAXIMUM TEMPERATURE ( HC version only ): the purifier is fitted with an
internal catalyser, the te perature of which is constantly aintained at 420°C
To guarantee safety, a co pletely independent device is fitted which shuts off
power supply to the heating ele ent when te perature values exceed 480°C

2. close the nitrogen line downline of the generator
3. switch on the generator, by setting the POWER switch to ON (see par. 6.5.
Generator start-up
)
4. start nitrogen production by pressing the START key (see par. 6.6. Nitrogen
production
)
5. wait approxi ately 15 inutes, until the generator reaches the Stand-By
status. In this state, the generator suspends nor al production, showing the
following page:
6. fro this point the nitrogen is available for the line, by opening the valve closed
in point 2.
e For the odel NiGen GC HC, it is suggested to supply gas to the application only
when the catalyzer has reached the operating te perature (approx 45 inutes
after switch ON)
e WARNING: On initial start-up, the internal nitrogen storage tank will initially con-
tain air. For this reason, the line should be vented with the gas (for approx. 60
inutes) before e ploying the nitrogen for the application utility.
