Rainman Auto Flush

The Autoflush System incorporates a solid-state timer, a motorized valve, and an activated carbon filter to allow your boat’s fresh water supply to push freshwater from your boat’s tanks through your watermaker for a few minutes every seven days.  The one-button programmable timer can be set between two and eight minutes flush cycle, depending on how strong your pump is.  The activated carbon filter will neutralize chlorine that may be in your tank from municipal water sources.

The timer and motorized valve operate from 12-24VDC.  One side of the system is plumbed to your boat’s freshwater supply while the other side is plumbed into your Rainman Pressure Supply Unit (PSU).  The system is delivered with two activated carbon filter cartridges, which should be replaced every six months.

Although the Autoflush System is sold as an option with new Rainman watermakers, it is fully compatible with older Rainman systems that have been installed.
