Double Stage Automatic Changeover Low Pressure …

1 P. 3 PRODUCT DESCRIPTIONPart 2 Part 2 REGULATORS FORCAMPING AND CARAVANDOUBLE Stage LOW PRESSUREThe type 924C is a regulating system with the function of Automatic changeoverof the withdrawal, conceived, in order to be used on caravans and autocaravansand it has been built in compliance with the standard EN 12864 annex D. Thedouble Stage Automatic Changeover regulator, type 924C, is a combination con-sisting of an Automatic Changeover working as a 1st Stage coupled to a 2nd Automatic Changeover (1st Stage regulator) reduces the Pressure at the out-let from the cylinder to a value of 500 mbar max; The 2nd Stage regulator redu-ces further the gas Pressure to the utilization Pressure value of 30 Automatic Changeover ensures continuous gas flow, automatically changingthe gas withdrawal from the exhausted "service" cylinder to the full "reserve" one.

2 The full-empty indicator assembled into the Changeover handle indicates theexhaustion status of the "service" cylinder. The indicator colour changes fromgreen to red, when the "service" cylinder is exhausted. The rotation of the Automatic Changeover handle to the full "reserve" cylinderrestores the green colour on the indicator.

The Double Stage regulator, type 524C, is a combination consi-sting of a 1st Stage high Pressure regulator and of a 2nd Stage lowpressure regulator. The 1st Stage regulator reduces the Pressure at the outlet fromthe cylinder to a value of 10 PSI max; then, the 2nd Stage regula-tor reduces further the gas Pressure to the utilization pressurevalue of 11" wc.
