Introduction
The Rainman autoflush kit is an optional accessory for customers that have installed their Rainman watermaker. It
is designed so that owners do not need to pickle their system, but instead pumps fresh water through the
watermaker every seven days. This prevents fouling of the reverse osmosis membranes.
The system utilises the boat’s main water pump, a Rainman flush timer box, a motorised valve, and an activated
carbon filter (neutralises chlorine that may be in your water tank) to force fresh water through your watermaker
for several minutes every seven days. The flush timer has a simple one button programmable capability for ease
of use. Below are conceptual schematics of how the system might look when installed.
