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 BHL series is engineered for 24 hours per day, 7 days per week operation.
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.

Owners Manual

INSTALLATION INSTRUCTIONS
Mount the desalination system in a cool and dry location, not higher than 30ft above low water level at a
distance not further than 100ft / 30m.
The electrical connection should only be done by a professional electrician. Check the correct
volta e before installin the system.
The “MA N” marked cable is to be connected to the power supply. The smaller cable, marked “PUMP”
is to be connected to the seawater feed pump or should be insulated / removed where pressurized
seawater is available.
FRESH WATER FLUSH FILTER
nstall the fresh water flush filter housing at a location near the desalination system. Connect the flush
port of the three-way service valve at the pre-filter assembly with the outlet of the flush filter housing
(OUT). Supply pressurized fresh water to the shut off valve of the flush filter housing.
SEAWATER FEED PUMP AND PRIMING RESERVOIR
(Optional Equipment)
With the aid of the priming reservoir, the feed pump is able to prime the seawater up to a height of 9ft.
Mount the feed pump in a dry location not higher than 9ft above low water level. Mount the priming
reservoir with the outlet (lower connection) at the same level as the intake of the feed pump in a dark
location (inhibits growth of algae). Connect the intake of the feed pump and the outlet of the priming
reservoir with 3/4”PVC pipe or directly if possible. Avoid elbows/90 degree fittings in your plumbing.
The complete pump head can be turned in case the outlet direction is not suitable for your installation.
The suction pipe (PVC 3/4”) connected to the intake of the priming reservoir (upper connection), need to
lead in one single vertical run below the waterline. From this point the pipe can run submer ed to the
supplied intake strainer (max 60ft / 20meters) where clean seawater can be taken in. A ¾” non-return
valve is to be installed in the suction pipe at any position below the waterline.
Connect the outlet (upper connection) of the priming reservoir with the marked (Seawater n) port of the
system’s pre-filter housing.
f the seawater or seawater well level is lower than 9ft below the location of the system’s seawater feed
pump, an additional supply pump will be needed. Submergible pumps are preferred and should feed the
system’s supply pump with a pressure of 3 to 20psi at a flow of 3.6gpm. The priming reservoir will not
be necessary. The use of an intermediate seawater storage tank at the level of the desalination system
also might be considered.
The use of a standard back washable sand filter, as used for swimming pools can reduce pre-filtration
cost especially when an open seawater intake is used.

PRODUCT WATER TUBING
Run the blue product water tubing or for longer distances than 15ft / 5m a 1/2" PVC hose or pipe from
the marked (Tank) outlet of the flow control panel to your fresh water storage tank. Run blue product
water tubing from the marked (Test) outlet of the flow control panel to a taste/test station of your choice.
Do not allow the product line to become blocked while the system is running. t must be avoided that
chlorinated water from your storage tanks sucks back into the RO membranes. Therefore, lead the
product water into the tanks above water level.
The Product water can be led to the storage tanks up to a height of 20m/65ft. n this case a non return
valve must be installed in the product line to protect the membrane from back-pressure.
REJECT WATER TUBING/HOSE
Connect the outlet of the pressure control valve on the back of the flow control panel of the desalination
system with a 1/2” reinforced PVC hose to a reject (brine) 1/2” PVC pipe. The brine should be disposed
of as far as possible (30ft / 10m) and down current from the seawater intake.

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?
1) Open the pressure control valve on the control panel all the way, counter-clock wise.
2) Set the flush/service valve at the pre-filter assembly to the run position (center) an open
the shut off valve at the pre-filter’s seawater intake.
3) For the initial start up an after filter changes, set the selector switch on the electrical
control panel to the “FEED” position (fee pump only) an purge the system until all
entrappe air has escape .
4) In the “AUTO” position, press the “START” button until the pressure on the low
pressure gauge “OUT” has buil up. If the high pressure pump motor stops, purge the
system again an start the system in the “AUTO” position as before.
5) Close the pressure control valve slowly clockwise an increase the operating pressure
until the specifie fresh water output for your mo el is achieve , not excee ing 800PSI.
Caution: Never allo any leaks in your hose or pipe connections. Do not attempt to re-
tighten. Al ays re-seal ith Teflon tape or change O-rings as required.
6) Check the quality of the pro uct water with the TDS meter. If the water is pure (un er
500ppm TDS), switch the iverter valve on the control panel to the storage tank position.
SYSTEM SHUT DOWN PROCEDURE
1) Switch the iverter valve to the sample 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).

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 shoul fresh water flush your watermaker after every use or infuse a bioci e solution for long
term storage. The fresh water flush prepares your watermaker for a shut own perio of seven ays
maximum. You can repeat the flush proce ure every seven ays, to exten the short term storage.
1) Open the pressure control-valve all the way counter-clockwise.
2) Close the seawater intake-valve on the pre-filter assembly an 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 shoul now turn on. Allow fresh water to flow until all salt water is flushe out of
the system.
For the next flush proce ure, test how long it takes until the brine at the reject outlet of
the watermaker becomes fresh.
4) Close the fresh water flush valve an the seawater shut off valve.
MEMBRANE STORAGE PROCEDURE
If you inten to store your watermaker for more than ten ays, growth of microorganism will
egra e the RO membranes performance.
The RO membranes shoul be flushe with a bioci e 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-chlorinate 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 iverter 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 an start the high pressure
pump only by hol ing own the start-button in the selector switch “Off” position.
5) Infuse the storage solution with the service hose connecte to the three-way valve while
running the high-pressure pump without pressure. Press an hol the “START” button
with the selector switch in the “OFF” position (high pressure pump only). When the
solution has been infuse , release the start button an remove the pre-filter cartri ges for
ry storage.
Un er best con itions your watermaker is now prepare for a shut own perio of ten months.
Discar the pro uct water for at least thirty minutes of initial operation, after storage, before
rinking or before use in foo 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 seawater 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 in intervals for up to one hour wi hou pressure (observe the maximum
operating temperature of 112° F / 45° C). Open the pressure control valve all the way
anti-clockwise and start the high pressure pump only, by holding down the start-button in
the selector switch “Off” position. 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
