2.1. Warnings
m lace the generator FAR FROM SOURCES OF HEAT
m lace the generator in an environment ROTECTED AGAINST RAIN
AND WIND
c NEVER O EN the generator while it is connected to the electrical
mains. RISK OF FATAL INJURY BY ELECTROCUTION
e Repairs and inspections ust be carried out exclusively by S ECIALIST ER-
SONNEL: in the event of faults i possible to solve according to one of the pro-
cedures in the TROUBLESHOOTING chapter, contact exclusively a CLAIND
technical service centre
e If the generator is not to be used for a prolonged period of ti e, it ust be ade-
quately depressurised (see par. 6.5. and par. 6.6.)
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.

7. Maintenance
To facilitate observance of adequate scheduled aintenance by the user, the ge-
nerator is equipped with a list of co ponents subject to wear, for which, during
the test phase, a working interval is set.
During operation this ti e interval decreases through to expiry, at which point
there is an auto atic request for aintenance.
7.1. Expiry warnings
During production, if the esti ated autono y of a device expires, a essage is
displayed, an exa ple of which is shown below .
WARNING
FILTER IN EXPIRY PHASE
To acquire the essage, press function key . The essage is then re oved
to proceed with nor al operation.
On subsequent restart the generator requests whether the aintenance has
been perfor ed, with display of the following essage:
