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.
