FRESH WATER FLUSH PROCEDURE
Caution: The fresh ater pressure should not exceed the range of the lo pressure gauge/s.
The installation of a pressure reducer may be necessary.
You shoul fresh water flush your watermaker after every use or infuse a bioci e solution for long
term storage. The fresh water flush prepares your watermaker for a shut own perio of seven ays
maximum. You can repeat the flush proce ure every seven ays, to exten the short term storage.
1) Open the pressure control-valve all the way counter-clockwise.
2) Close the seawater intake-valve on the pre-filter assembly an make sure the shut off
valve on the flush filter is open.
3) Open the fresh water flush valve on the pre-filter assembly. Your fresh water pressure
pump shoul now turn on. Allow fresh water to flow until all salt water is flushe out of
the system.
For the next flush proce ure, test how long it takes until the brine at the reject outlet of
the watermaker becomes fresh.
4) Close the fresh water flush valve an the seawater shut off valve.

2) In a clean plastic container, mix 5 gallons / 20 litres of un-chlorinate fresh water with
200 grams (2/3 container) of Echo Tec. Preservative # 3.
3) Switch the three-way valve to the service position. Switch the iverter valve to the
sample position. Switch the shut off valve to the off position.
4) Open the pressure control valve all the way anti-clockwise an start the high pressure
pump only by hol ing own the start-button in the selector switch “Off” position.
5) Infuse the storage solution with the service hose connecte to the three-way valve while
running the high-pressure pump without pressure. Press an hol the “START” button
with the selector switch in the “OFF” position (high pressure pump only). When the
solution has been infuse , release the start button an remove the pre-filter cartri ges for
ry storage.
Un er best con itions your watermaker is now prepare for a shut own perio of ten months.
Discar the pro uct water for at least thirty minutes of initial operation, after storage, before
