Whisper 60 modular Guide
6.0 Maintenance
6.2 Short Term Storage/Fresh Water Flush
Ideally, the SEA STAR Whisper 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
14 days
OR
idle for seven days in hot, tropical climates. 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) - Handle to the
Fresh Water Line. Make sure that the ships pressure water system is ON
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.
Change the pre-filter to a new filter. Leaving the old filter in could cause contamination.
Now you can leave the System in Stand-by for 3-4 Months. In very hot climates only one month.
