Page 5: Options And Accessories
OPTIONS AND ACCESSORIES 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. The boost pump also extents pre-filter element life, reduces maintenance and assists in priming the system after pre-filter changes. Boost pump with intake hose barb, outlet hose barb, 4 feet / 1.2 meter wire reinforced intake hose, 10 feet / 3 meter braided feed hose, 5 micron pre-filter option. -

Page 7: Installation Instructions
INSTALLATION INSTRUCTIONS HIGH PRESSURE PUMP/MOTOR UNIT Mount the high pressure pump/motor unit horizontally in a dry and ventilated location. Maximum ambient temperature for continuous duty is 40˚C / 104˚F. CAUTION: Motor gets hot during prolonged operation. PRESSURE VESSEL (MEMBRANE HOUSING) Mount the pressure vessel(s) with the provided brackets vertical (with the flow upwards) or horizontal in a convenient location away from the heat of the engine as close as possible to the high pressure pump. -
Page 8: Sea Strainer
SEA STRAINER Mount the sea strainer with the provided 3/4" NPT nylon nipple directly to the intake of the 20 micron pre-filter housing. If an optional boost pump is required (refer to “Available Options and Accessories”), mount the sea strainer under the waterline in a serviceable location in between the sea-cock of your choice and the boost pump. - Page 9 3) Rotate the socket (outer part) anti clock wise on to the hose until hose bottoms. Back the hose out ½ turn to allow for expansion of the hose during assembly. 4) Apply dishwashing liquid mixed 1:1 with water on to the nipple (inner part) of the high-pressure fitting and the inside of the hose.

Page 10: Electrical Installation
HARDENER / PH NEUTRALIZER KIT The ECHOTec post treatment element contains a mixture of minerals that returns bicarbonate alkalinity, correcting pH only enough to reach a neutral equilibrium. This dramatically reduces corrosion on metal tanks, boilers, washing machines and plumbing due to acidic product water. - Page 11 INSTALLATION INSTRUCTION – OPTIONAL EQUIPMENT BOOST PUMP Install the boost pump with the electric motor sideways (horizontal) in a dry location (submergible pumps are also available) below the water line, in between the sea strainer and the pre-filter(s). The intake is at the center of the pump.
- Page 12 SYSTEM OPERATION INSTRUCTIONS CAUTION: The reverse osmosis membrane contains a preservative solution to prevent microbiological growth. If ingested, it may cause irritation of the gastro-intestinal tract. Therefore, discard all the product water for at least thirty minutes of initial operation or after system storage before drinking or before use in food preparations! CAUTION: Do not operate the system using contaminated feed water sources (oil, chlorine or other chemicals).

Page 13: System Shut Down Procedure
SYSTEM SHUT DOWN PROCEDURE Switch the diverter valve to sample station. Open the pressure control valve all the way counter-clockwise. Switch off the electric motor and the boost pump (if installed). Close the seawater intake valve. FRESH WATER FLUSH PROCEDURE The fresh water flush prepares your watermaker for a shut down period of ten days. -
Page 14: Membrane Cleaning Procedure
In a clean plastic container, mix 2.5 gallons / 10 liters of un-chlorinated fresh water with 100 grams (1/3 container) of ECHOTec membrane preservative # 3 (Metabisulfite) for one and two 40” membrane systems. Mix 4 gallons / 15 liters of water with 150 grams (1/2 container) of preservative for three and four 40”... -
Page 15: Maintenance Timetable
It is important that most of the fresh water remaining from the last flush is dumped before the reject hose is led in the cleaning bucket for re-circulation in order to avoid diluting the solution. Use cleaning chemical #1 first. Only if the performance does not improve, use the acid cleaner #2 at the same ratio and instruction. MAINTENANCE TIMETABLE The following maintenance timetable is an estimate of the time intervals at which maintenance may be required only. -

TROUBLESHOOTING GUIDE MALFUNCTION CAUSE REMEDY Inability to build up Air enters intake plumbing. Tighten all hose clamps. pressure… Air in intake system Allow more time to prime. If no boost pump is installed, perform freshwater flush to assist priming..with high pressure High pressure pump valve Open one by one all six hexagonal valve gauge fluttering. - Page 17 MEMBRANE ELEMENT AND END PLUG SERVICE INSTRUCTIONS Remove the high pressure hoses and product tubing from the pressure vessel If needed remove the complete vessel/s Remove the three M6 bolts with a 5 mm allen key on both sides of the vessel. Remove the three locking plates (locks) on both sides.

Page 19: Servicing The Valves
SERVICING THE VALVES Using a 3/8” allen wrench, remove valve cap. Examine threads and o-ring. Replace o-ring if there is any evidence of cuts, abrasions, distortion or wear. Remove valve assembly (retainer, spring, valve, valve seat From valve cavity using a needle nose pliers. Remove valve seat o-ring from valve cavity. - Page 20 REPLACING CERAMIC PLUNGERS Using a 1/2” wrench or socket, remove the stainless steel fasteners retaining the plungers. Remove stainless steel washer and ceramic plunger from piston rod. If copper slinger washer comes off with plunger, be certain this is replaced before new plunger is installed. Install new o-ring and Teflon back-up ring on piston rod.
