INTRODUCTION
Thank you for choosing an ECHO Tec. reverse osmosis desalination system. We trust that you will
be completely satisfied with our product.
The Beach House eries has been specially designed for small hotels, marinas and beach houses.
The high power efficiency and low maintenance cost makes high quality RO water in many cases
more economical than land supplied water, if available.
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. uch problems are easily corrected
and require minor adjustments. If left unattended, a small problem in one component will affect the
rest of the system and can lead to an expensive repair.
If you have any doubts or questions, please contact us. We are happy to help “customize” the
seawater reverse osmosis desalinator for your special needs.

cable marked “F D PUMP” is to be connected to the feed pump or should be insulated / removed
where pressurized seawater is available.
SEAWATER FEED PUMP (Optional Equipment)
Mount the feed pump in a dry location below the waterline of the vessel. Connect the intake of the feed
pump with the vessel’s sea strainer. Connect the outlet of the feed pump with the intake of the
desalination system located at the pre-filter assembly. Secure all hoses with the supplied hose clamps.
PRODUCT WATER TUBING
Connect the product water outlet marked “SAMPL ” with a test station of your choice. Connect the
product water outlet marked “TANK” to your storage tank.
REJECT WATER TUBING/HOSE
Connect the outlet of the pressure control valve on the back of the flow control panel with the 1/2”
reinforced PVC hose to a thru hull fitting preferably above the waterline or drain of your choice.
FRESH WATER FLUSH KIT
Install the fresh water flush filter housing at a location near to the desalination system. Connect the flush
port of the three-way service valve at the pre-filter assembly of the desalination system with the outlet of
the flush filter housing marked “OUT”. Supply pressurized fresh water to the shut off valve of the fresh
water flush filter housing.

SYSTEM OPERATION INSTRUCTIONS
The reverse osmosis membrane contains a preservative solution to prevent microbiological
gro th. If ingested, may cause irritation of the gastro-intestinal tract, colic, diarrhea, or other
similar symptoms.
Therefore, discard all the product ater 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 ater sources (oil, chlorine or other
chemicals).
Have you filled the high-pressure pump ith the proper amount of oil (SAE90 gearbox oil)?
1) Open the seacock and the seawater shut off valve on the pre-filter assembly.
2) Open the pressure control valve on the flow control panel all the way, counter-clock wise.
3) Set the flush service valve at the pre-filter assembly to the “CLOSED” position (center).
4) Set the diverter valve on the flow control panel to the sample “TEST” position.
5) For the initial start up and after filter changes, set the selector switch on the electrical
control panel to the “FEED” position (feed pump only) and purge the system until all
entrapped air has escaped.
6) In the “AUTO” position, press the “START” button until the pressure on the low
pressure gauge “OUT” has build up. If the high pressure pump motor stops, purge the
system again and start the system in the “AUTO” position as before.
7) Close the pressure control valve slowly clockwise and increase the operating pressure
until the specified fresh water output for your model is achieved not exceeding 800PSI.
Caution: Never allo any leaks in your hose or pipe connections. Reseal ith Teflon tape
or change O rings as required.
8) Check the quality of the product water with the TDS meter. If the water is pure (under
500ppm TDS), switch the diverter valve on the control panel to the storage tank position.
SYSTEM SHUT DOWN PROCEDURE
1) Switch the diverter valve to the “TEST” position.
2) Open the pressure control valve all the way counter clockwise.
3) Switch the selector switch off.
4) Fresh water flush the system (see next page).
5) Close the seawater shut off valve on the pre-filter assembly and the seacock.

FRESH WATER FLUSH PROCEDURE
Caution: The fresh ater pressure should not exceed the range of the lo 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.
1) Open the pressure control-valve all the way counter-clockwise.
2) Close the shut off valve on the pre-filter assembly and make sure the shut off valve on the
flush filter is open.
3) Open the fresh water flush valve on the pre-filter assembly. Your fresh water pressure
pump should now turn on. Allow fresh water to flow until all salt water is flushed out of
the system (1-2 mins).
For the next flush procedure, test how long it takes until the brine at the reject outlet of
the watermaker becomes fresh (taste or use TDS meter).
4) Open the seawater shut off valve and back flush the pre-filter system with fresh water.
5) Close the fresh water flush valve, the seawater shut off valve and the seacock.
MEMBRANE STORAGE PROCEDURE
If you intend to store your watermaker for more than ten days, growth of microorganism will
degrade the RO membranes performance.
The RO membranes should be flushed with a biocide solution to preserve the membrane for long-
term storage of up to ten months.
1) Fresh water flush the system.
2) In a clean plastic container, mix 5 gallons 20 litres of un-chlorinated fresh water with
200 grams (2 3 container) of Echo Tec. Preservative # 3.
3) Switch the three-way valve to the service position. Switch the diverter valve to the
sample position. Switch the shut off valve to the off position.
4) Open the pressure control valve all the way anti-clockwise.
5) Infuse the storage solution with the service hose connected to the three-way valve while
running the high-pressure pump without applying pressure. Press and hold the “START”
button with the selector switch in the “OFF” position to run the high pressure pump only.
When the solution has been infused, release the start button and remove the pre-filter
cartridges for dry storage.
Under best conditions your watermaker is now prepared for a shut down period of ten months.
Discard the product water for at least thirty minutes of initial operation, after storage, before
drinking or before use in food preparations.

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 fre uency 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. Cleaning of
the membranes will not enhance the uality (TDS reading) of the product water.
CAUTION: The use of chemicals or cleaning me hods o her han hose ou lined in
he cleaning ins ruc ions will void he ECHO Tec. warran y. Nonionic surfac an s
for membrane cleaning or o her chemicals no approved in wri ing by Echo Marine
L d. will void he elemen warran y.
CAUTION: Cleaning chemical #1 is an alkaline de ergen . See warning label on
side of he con ainer and observe all safe y precau ions on label.
CAUTION: Cleaning chemical #2 is an acid, a mineral scale remover. See warning
label on side of con ainer and observe all safe y precau ions on label.
CAUTION: Do no mix differen cleaning chemicals oge her. Do no use differen
cleaning chemicals oge her a he same ime. Mix he cleaning chemicals separa ely
and use hem separa ely.
No e: All cleaning and preserving procedures can be done with either sea water or non-
chlorinated freshwater. However, the cleaning process is more effective using non-
chlorinated freshwater.
To clean the ECHO Tec. reverse osmosis membranes mix one container (330gram) of
cleaning chemical #1 with 5gal / 20ltr of water at 104° F / 40° C.
Re-circulate (disconnect the reject water hose and lead it in the cleaning container) the
solution wi hou pressure for up to 60 min. (observe the maximum operating
temperature of 112° F / 45° C). Do not allow the cleaning container to run dry or air to
enter the system.
It is important that the fresh water, remaining from the last flush is dumped before the
reject hose is led in the cleaning container to ensure the re-circulation of the undiluted
cleaning solution only.
Use cleaning chemical #1 first. 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. 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.
