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 housing, bracket and cartridge (all assembled). -

Page 7: Installation Instructions
INSTALLATION INSTRUCTIONS 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 ECHOTec watermaker models: 400 - 500: 900 RPM... -
Page 8: Control Panel
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. The membrane is sealed within its housing by plugs at both ends. Inside the housing is a small amount of preservative to keep the membrane moist and prevent bacterial growth. -
Page 9: High Pressure Hose
HIGH PRESSURE HOSE The high pressure hose has factory mounted high pressure couplings on each end (also included are two field attachable fittings). This hose comes in a 15 feet / 4.5 m length, so it may be cut to suit your needs. Leave a little extra length of hose to avoid stress on the system components. -
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 submersible boost pump with the electric motor sideways (horizontal) below the water line, in between the sea strainer and the pre-filter(s). The intake is at the center of the pump. The outlet should ideally point upwards or sideways with the fitting to the top to prevent air pockets.
- 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. -
Page 16: Troubleshooting Guide
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 covers. - 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 Remove the three M6 bolts with a 5mm allen key on both sides of the vessel. Remove the three locking plates (locks) on both sides.
- Page 18 HIGH PRESSURE PUMP PARTS AND SERVICE INSTRUCTIONS DISASSEMBLY SEQUENCE OF THE PUMP HEAD Remove the three discharge valve plugs and the three inlet valve plugs (32), with a 22 mm socket wrench. Inspect the O-ring (33) for wear and replace if damaged. With needle nose pliers, remove the inlet and discharge valve assemblies (32X).
- Page 19 If the crankcase oil seals (19) are to be replaced, they can be removed by prying loose. Take care not to make contact with the plunger. If the oil seals are not to be replaced, proceed to the back end disassembly sequence and carefully pry the seals loose after the plungers have been removed from the crankcase.
- Page 20 ECHOTEC WATERMAKERS LIMITED WARRANTY Echo Marine Ltd. warrants for a period of 3 years (1 year for commercial applications) from the date of shipment that the ECHOTec watermaker is free of defects in material and workmanship and performs according to specifications. The triplex plunger high-pressure pump head and the high pressure vessel/s (except end plugs, O-rings and fittings) are warranted for life (10 years for commercial applications) to the original purchaser.
- Page 21 The ECHOTec Membrane Element is warranted to be cleanable for a minimum of one year from date of shipment, provided that cleaning instructions are adhered to and foulant is acid soluble metal hydroxides and calcium carbonates or alkaline soluble organic, inorganic substances and microbiological slimes.
