The external water monitor can be used as an additional safety precaution where there is a direct water connection (automatic feeding device) for the B 500. The water monitor is fitted with an independent water valve attached between the safety pressure hose and the water tap. The warer monitor´s sensor (cable length: 2m) is placed in the safety collection reservoir and shuts off the external water feed to the humidifier when it comes into contact with water. An acoustic signal also sounds and this can only be deactivated by interrupting the power supply. Installation may take place only with technical personnel!
