Less than 12" high, the Nano ECO is ideal for installation on the raised platform typically found in the head compartments of many boats. The self-contained, energy-saving design features a user-controllable flush and teams a powerful turbine macerator pump with a high-pressure jet nozzle that quickly cleans the bowl with minimal water, for more flushes per tank. It includes a rocker-style flush switch. Installation requires choice of an installation kit. Freshwater ECO Kit utilizes onboard freshwater and the vessel's existing freshwater pump to flush. Raw Water ECO Kit utilizes externally drawn water and a dedicated pump, which is supplied.
