Service Kit Waste Tank Replacement Lid with Sensor - GreyThe Grey Waste Tank enables the user to manage all grey waste onboard easily, through one skin fitting. The Intelligent Control sensor integrated into the tank lid provides automatic operation of the grey waste pump. The sensor will detect water in the grey waste tank at a pre-determined level, and will automatically activate the grey waste pump. When the tank is emptied, the switch will automatically turn the grey waste pump off. The 2 sensor models include a second sensor that can be used to control a second grey waste pump. It is factory set to activate at a higher water level and will provide additional pumping capacity during periods of high inflow to the grey waste tank. Alternatively, the second sensor can be wired to a high-level alarm, warning of a high water level within the grey waste tank. Brochure (pdf)
