WARNING Read before you start
It is imperative that all maintenance procedures be conducted exclusively by duly qualified personnel.
Should the necessity arise, it is recommended to contact our technical support representatives or our authorized
dealers.
It is important to note that the regulator and its associated pressure components are susceptible to the effects of
normal wear and tear. Therefore, it is essential to conduct regular inspections and, when necessary, replace these
components to ensure optimal performance and safety.
The frequency of inspection, examination, and replacement is contingent upon the severity of the service conditions
and in accordance with the relevant national or industry codes, standards, and regulations/recommendations.
In accordance with applicable national or industry codes, standards, and regulations/recommendations, all hazards
covered by specific tests after final assembly before applying the CE marking shall be covered also after every
subsequent reassembly at the installation site. This is done to ensure that the equipment will be safe throughout its
intended life.
Prior to commencing any maintenance procedures, it is imperative to shut off the gas supply at both the upstream
and downstream points from the regulator. Furthermore, it is essential to ascertain that there is no residual gas pres-
sure within the regulator body itself by loosening the upstream and downstream connections. Upon completion
of the aforementioned steps, it is then necessary to conduct a visual inspection for any potential leaks using a soap
solution.
