9.2 Maintenance
Even though the equipment is reliable, it must be checked
periodically.
Since this task requires some precautions, it must be done
exclusively by a qualified technician.
The periodicity of this verification depends essentially on the
usage of the equipment (intensive, moderate, occasional).
We suggest the use of the following table to ensure an opti-
mum usage of your equipment:
V – to verify
C – to change

The system should be checked by the manufacturer once a
year for functional and operational safety. We recommend a
maintenance contract – please do not hesitate to contact us.
The annual check of the flame back arrestors at downstream
point of us is required by law. The proof of this must be pro-
vided by the operator.
Flexible hoses must be checked as required, at least at inter-
vals within one year, in terms of their condition (integrity and
tightness) by an expert or by the manufacturer.
