INTRODUCTION Thank you for choosing an ECHO Tec. reverse osmosis desalination system. We trust that you will be completely satisfied with our product. The purpose of this manual is to allow you to become familiar with each component of your new ECHO Tec. desalination system. By understanding the function, importance and normal operation of each part in the system, the operator can readily diagnose problems when they first develop. Such problems are easily corrected and require minor adjustments.
SPECIFICATIONS Rated Performance: ECHO Tec: 20 gallons – 75ltr. / hour 38 gallons – 140ltr. / hour 50 gallons – 210ltr. / hour 60 gallons – 260ltr. / hour 500 – PRO – 1 900 – PRO – 2 1200 – PRO – 3 1500 – PRO – 4 Reverse Osmosis performance varies with the feed water temperature and salinity. The rated performance is tested at 26°C / 80°F water temperature at a salinity of 35g/l. A decrease in product water quantity of 10 to 15% in the first year is normal and expected.
STANDARD SYSTEM FEATURES 1) 1 High-pressure pump unit with controls 2) Pressure vessel rack with reverse osmosis membrane vessel(s) 500-PRO-1 one 40” vessel ECH2O Tec.
INSTALLATION INSTRUCTIONS HIGH PRESSURE PUMP UNIT Mount the high pressure pump unit in a cool and dry location using all five mounting holes. The electrical installation should only be done by a professional electrician. Check the correct voltage before installing the system. The cable labeled with the system’s voltage and frequency is to be connected to the power supply.
PRE-FILTER ASSEMBLY Mount the pre-filter in a serviceable location and connect the intake port to the outlet of the raw water feed pump or multi-media sand filter (optional). For short runs, use 5/8” reinforced PVC hose. For longer runs, use a 5/8” or 3/4” PVC pipe. Connect the outlet of the pre-filter housing with a 3/4” reinforced PVC hose to the intake of the high pressure pump. Install all plumbing to eliminate any air pockets in the system.
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 or after storage before drinking or 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. You should fresh water flush your watermaker after every use or infuse a biocide solution for long term storage. The fresh water flush prepares your watermaker for a shut down period of seven days maximum. You can repeat the flush procedure every seven days, to extend the short term storage.
MEMBRANE CLEANING PROCEDURE The membranes of the ECHO Tec. Watermaker must be chemically cleaned when the product water output drops by 20% of the specified amount. The frequency of this occurring will vary greatly depending upon feed water. Fouling of the membranes 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.
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. COMPONENT MAINTENANCE REQUIRED TIME INTERVAL INTERMITTENT DUTY Seawater intake strainer Inspect and clean intake. 1000 hrs, or when clogged.
MEMBRANE CHANGING PROCEDURE PRESSURE VESSEL END PLUG CHANGING PROCEDURE 1) 2) 3) 4) 5) Remove the product port (if installed) and the high pressure fitting. Remove the two/three M6 bolts. Remove the two/three 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.
