Page 7: High Pressure Pump
INSTALLATION INSTRUCTIONS (BELT DRIVEN) HIGH PRESSURE PUMP To minimize vibration, it is best to build brackets on the motor itself, similar to alternator brackets. Use cardboard to construct a pattern first before making these brackets. The high-pressure pump has a maximum RPM of 1750. The recommended working RPM is 1450. Minimum RPM for ECHO Tec. -
Page 8: Control Panel
CONTROL PANEL Mount the control panel in an easily accessible location as close as possible to the membrane housing(s). SEA STRAINER Mount the sea strainer with the provided 3/4" NPT nylon nipple directly to the intake of the 20micron pre-filter housing. If an optional boost pump is required (refer to “Available Options and Accessories”), mount the sea strainer in a serviceable location in between the seacock of your choice and the boost pump. - Page 9 Run one of the high-pressure hoses from the output of the HP pump (O ring sealed fitting) to the O ring sealed fitting at the end of the membrane that is marked IN. A minimum hose length of 3 feet/1M is required for pulsation dampening. The hose can be coiled where needed.
- Page 10 INSTALLATION INSTRUCTION (OPTIONS) BOOST PUMP Install the boost pump with the motor up or sideways in a dry location below the water line, in between the sea strainer and the pre-filter(s). The intake is at the center of the pump. Avoid elbows/90 degree fittings in your plumbing.

Page 11: System Shut Down Procedure
SYSTEM OPERATION INSTRUCTIONS 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). - Page 12 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.
-
Page 13: Membrane Cleaning Procedure
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. Increased amounts of fouling without proper cleaning of the membrane will reduce the performance of your water maker. -
Page 14: Maintenance Timetable
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. - Page 15 MEMBRANE CHANGING PROCEDURE PRESSURE VESSEL END PLUG CHANGING PROCEDURE Remove the product port (if installed) and the high pressure fitting. Remove the two/three M6 bolts. Remove the two/tree locking plates (locks) Remove the backing plate Pull the end plug with the aid of a hand tight inserted product port in one fast pull. Should the plugs O-ring (PL01)get stuck in the groove of the pressure vessel, it will be more difficult to pull the plug.
