8. PRESSURE RELIEF VALVE (where provided)
8. 1 Instructions and limits of use
Replacement of the pressure relief valve is suggested whenever; during the drainage, the build-up of
component processing and pipe residues happens to make the shutting of the seal defective.
Before you replace the valve, make sure that the system is not under pressure or at high-level
temperature in the area you are operating.
8. 2 Maintenance/inspection and valve setting
Warning! Maintenance is not provided for pressure relief valves. The removal of the cap or the
tampering of the seal are considered unauthorized modifications of the setting. This will void the
manufacturer's guarantee.
