FRESH WATER FLUSH PROCEDURE
Caution: The fresh water pressure should not exceed the range of the low pressure gauge/s.
The installation of a pressure reducer may be necessary.
You should fresh water flush your watermaker after every use or infuse a biocide solution for long
term storage. The fresh water flush prepares your watermaker for a shut down period of seven days
maximum. You can repeat the flush procedure every seven days, to extend the short term storage.
1)
Open the pressure control-valve all the way counter-clockwise.
2)
Close the shut off valve on the pre-filter assembly and 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 should now turn on. Allow fresh water to flow until all salt water is flushed out of
the system (1-2 mins).
For the next flush procedure, test how long it takes until the brine at the reject outlet of
the watermaker becomes fresh (taste or use TDS meter).
4)
Open the seawater shut off valve and back flush the pre-filter system with fresh water.
5)
Close the fresh water flush valve, the seawater shut off valve and the seacock.
MEMBRANE STORAGE PROCEDURE
If you intend to store your watermaker for more than ten days, growth of microorganism will
degrade the RO membranes performance.
The RO membranes should be flushed with a biocide solution to preserve the membrane for long-
term storage of up to ten months.
1)
Fresh water flush the system.
2)
In a clean plastic container, mix 5 gallons / 20 litres of un-chlorinated 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 diverter 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.
5)
Infuse the storage solution with the service hose connected to the three-way valve while
running the high-pressure pump without applying pressure. Press and hold the “START”
button with the selector switch in the “OFF” position to run the high pressure pump only.
When the solution has been infused, release the start button and remove the pre-filter
cartridges for dry storage.
Under best conditions your watermaker is now prepared for a shut down period of ten months.
Discard the product water for at least thirty minutes of initial operation, after storage, before
drinking or before use in food preparations.
