INSTALLATION INSTRUCTION - OPTIONS BOOST PUMP If the high-pressure pump is installed less than 1 foot below the waterline or an additional 5micron pre- filter is added, the installation of an optional boost pump is recommended. Install the boost pump with the electric motor up or sideways in a dry location (submergible pumps are available) below the water line, in between the sea strainer and the pre-filter(s).
SYSTEM OPERATION INSTRUCTIONS (AC VERSION) The reverse osmosis membrane contains a preservative solution to prevent microbiological growth. If ingested, may cause irritation of the gastro-intestinal tract, Colic, diarrhea, or other similar symptoms. Therefore, discard all the product water for at least thirty minutes of initial operation, after storage before drinking or before use in food preparations! Do not operate the system using contaminated feed water sources (oil, chlorine or other chemicals).
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. If you don’t use your watermaker for the next three days, you will need to flush your system with fresh water or infuse a biocide solution.
MEMBRANE CLEANING PROCEDURE The ECHO Tec. Watermaker must be chemically cleaned when the product water output drops by 15% of the specified amount. The frequency of this occurring will vary greatly depending upon feed water. Fouling of the membrane will naturally occur during normal usage of the ECHO Tec. Watermaker.
MAINTENANCE TIMETABLE The following maintenance timetable is an estimate of the time intervals at which maintenance may be required only. This schedule must be adjusted to the regularity of usage, the condition of the intake water, the length of time the system is exposed to seawater and the total running time following each system cleaning.
