Page 3: Specifications
SPECIFICATIONS RATED PERFORMANCE: ECHOTec Model Gallons per hour Liters per hour 200 - DML - 1 240 - DML - 1 260 - DML - 1 Reverse Osmosis performance varies with the feed water temperature and salinity. The rated performance is tested at 26C / 80F water temperature and 33g NaCl/ltr. RO MEMBRANE TYPE: Standard size high rejection TFC Polyamide, thin film composite, spiral wound, single pass reverse osmosis element.
Page 4 STANDARD SYSTEM FEATURES 1 PVC sea strainer 2 3/4” NPT x 5/8” barbed hose connection Pre-Filter complete with 20 micron cartridge (5 and 20 micron with optional boost pump) 1 Stainless steel bracket with 8 screws 1 Service valve with 1 Nylon nipple and 3 barbed hose connectors (with boost pump) or 1 flush/storage valve with 1 Nylon nipple and 1 NPT female tee (without boost pump) 1 Filter wrench 1 High-pressure pump unit with vibration dampers...
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, fittings and cartridge (all assembled).

Page 7: Installation Instructions
INSTALLATION INSTRUCTIONS HIGH PRESSURE PUMP 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 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 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 exchanges the seawater in the membrane element/s with fresh water und should be performed after each use of the watermaker.
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) Switch the three-way valve to the cleaning/storage position. Switch the diverter valve to the sample position. Open the pressure control valve all the way counter clockwise (two full rounds after the spring releases).
Page 15: 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 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. Open one by one all six hexagonal valve covers..with high pressure High pressure pump valve Inspect valves for movement.
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 Refer to the pump diagram. 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.
