6.2 Short Term Storage/Fresh Water Flush
Ideally, the SEA STAR performs optimally when the RO unit is used periodically. However, the
Likelihood of bacterial and biological growth in the membranes increases, when stagnant seawater (in
extended periods) is in contact with the membranes. A freshwater flush procedure is necessary to
prevent clogging and growth of organic contaminants in the RO system and its membranes. This
method pushes out older stagnant seawater (saltwater) out of the membranes and replacing it with
freshwater (non-saltwater), leaving less chance of fouling the membranes. The freshwater flush
procedure should be used when
the unit will be placed idle or in “stand by” condition for more than
seven days OR idle for three days in hot, tropical climates. We recommend a fresh water flush after
every use. Although they do not attack the membranes or other system components directly, high
concentrations of biological matter can block enough of the product water channels to cause a
reduction of as much as 40% of the total system capacity.
PERFORM A FRESHWATER FLUSH TO THE RO UNIT WITH NON-CHLORINATED FRESH
WATER ONLY. EXPOSING THE MEMBRANES TO CHLORINATED WATER WILL CAUSE
IRREVERSIBLE DAMAGE AND VOID THE RO UNIT WARRANTY. THE FRESHWATER FLUSH
SYSTEM USES A
CARBON FILTER INLINE BEFORE SYSTEM TO CONSUME THE CHLORINE.

Turn the handle at the strainer to Fresh Water Position (Selector Valve)

Start the unit.

Let the system run for app. 10 minutes. At least so long, until the high pressure has
dropped.

Stop the system.

Place the selector Valve back to Sea Water.

For storage longer than one week, replace the 5µ pre-filter. An old filter can contaminate
the system.
Now you can leave the System in Stand-by for 3-4 Months. In very hot climates only on month.
Note: A fresh water flush after using the system will increase the lifetime of the membrane. However, you should not
have sea water in the system for more than 2 days.
