The sensor signals if, in case of leakages, cooling agents (R22, R13â, R404 A, R407C, R507 etc..) get into the water.
Simultaneously, it serves as oil warning, as in the event of leakages in the Looling agent cycle, always oil gets into water, too.
In the line and/or the reservoir must be present overpressure of at least 0.2 bar. The maximum pressure may be 16 bar.
Due to its method of operation, the gas sensor serves simulaneously as automatic exhauster.
