INSTALLATION INSTRUCTIONS (BELT DRIVEN)
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 175 . The recommended working RPM is 450.
Minimum RPM for ECHO Tec. watermaker models: 200 - 500: 900 RPM
600 - 900: 050 RPM
200 - 500: 225 RPM
The high-pressure pump can run on lower RPM. This will decrease the specified production only.
Position the high-pressure pump horizontal with the dipstick up. The pump can turn in either direction.
Ensure proper pulley diameter on your engine. The electro magnetic clutch has a pulley diameter of
7”/177mm.
To determine the proper motor pulley size, use the formula below as a guideline.
PUMP PULLEY DIAMETER 7”/177mm X RPM PUMP = MOTOR PULLEY DIAMETER
RPM MOTOR
CAUTION: RE-TIGHTEN ALL FASTENERS AFTER 5 HOURS OF OPERATION AND
CHECK FREQUENTLY FOR BELT TENSION AND CHAFING OF HIGH-PRESSURE
HOSES.
A professional electrician should only do the electrical installation.
Connect the +wire of the magnetic clutch to the system switch on the control panel.
Supply 2V DC to the switch. This wire needs to be protected by a 0A fuse.
When the batteries minus are connected to the main engine, an additional –wire is not necessary.
Please seek professional advice when the main engine is isolated from the battery.
Fill the pump with 7.5 oz. / .22 ltr. Of SAE 9 non-detergent, non-toxic crankcase oil.
MEMBRANE HOUSING
Mount the high-pressure membrane housing(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 is a small amount of
preservative to keep the membrane moist and prevent bacterial growth.
The efficiency of the preservative, under best conditions, is approximately one year.
When all other components and hoses/tubes are completely assembled, remove the caps on the high-
pressure fittings and the sealed tube from the product water outlet on the membrane housing/s and then
finish making all final hose/tube connections. This will insure that the membrane is kept moist.
CONTROL PANEL
Mount the control panel in an easily accessible location as close as possible to the membrane
housing(s).
SEA STRAINER
Mount the sea strainer with the provided 3/4" NPT nylon nipple directly to the intake of the 20micron
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 seacock of your choice and the boost
pump.
To avoid excessive mechanical stress, do not connect/mount the sea strainer directly to the sea-
cock.
Connect the barbed fittings with the supplied coil reinforced intake hose and secure all hoses below
water level with two hose clamps. For boost pump installation refer to the “Installation Instructions”
(Optional Equipment).
PRE-FILTER HOUSING
Mount the pre-filter in a serviceable location and connect the bottom port of the cleaning / storage valve
to the bottom intake hose fitting of the high-pressure pump. Secure the hose with the two stainless steel
hose clamps. If the optional 3/4" nylon tee with flush/storage valve is supplied, connect the 3/4" hose
fitting on the tee to the bottom intake fitting of the high-pressure pump.
INSTALL ALL PLUMBING TO ELIMINATE ANY AIR POCKETS IN THE SYSTEM
CAUTION: USE A MAXIMUM OF THREE WRAPS OF TEFLON TAPE ON ALL THREADS
TO PREVENT LEAKAGE, IF YOU HAVE TO RE-SEAL FITTINGS. ALWAYS KEEP THE
TAPE BACK FROM THE END OF THE FITTINGS (AT LEAST TWO THREADS). DO NOT
ALLOW ANY TAPE TO ENTER THE SYSTEM.
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 20foot length, so it may be cut to suit your needs.
Leave a little extra length of hose.
Never bend the high pressure hose tighter than a 4”/1 cm radius.
Assembly instructions for the stainless steel field attachable high-pressure couplings:
) Cut the hose in a clean 90° angle (preferably with a cutting disc).
2) Un-assemble the coupling.
3) Rotate the outer part anti clock wise on to the hose.
4) Apply dishwashing liquid mixed : with water on to the nipple of the high-pressure coupling
(inner part) and the inside of the hose.
5) Counter the high pressure coupling with the supplied assembly tool (hexagonal plug) and screw
the nipple all the way into the hose.
Run one of the high-pressure hoses from the output of the HP pump (O ring sealed fitting) to the O ring
sealed fitting at the end of the membrane that is marked IN.
A minimum hose length of 3 feet/1M is required for pulsation dampening. The hose can be coiled
where needed.
Run the second high-pressure hose from the outlet of the RO membrane housing to the pressure control
valve in the control panel. Do not over tighten the high pressure fittings. They are O-ring sealed and
need little torque to lock only.
PRODUCT WATER TUBING
Connect the product water tubing from the center fitting(s) of the membrane housing(s) to the bottom
inlet of the flow meter, in the control panel. Connect the tubing from each output port of the 3-way
valve to your water tank and to the taste/test station of your choice.
CAUTION: UNDER NO CIRCUMSTANCES SHOULD THE PRODUCT WATER LINE BE
ALLOWED TO BECOME BLOCKED WHILE THE SYSTEM IS RUNNING.
DO NOT INSTALL SHUT-OFF VALVES ANYWHERE IN THIS LINE.
CAUTION: DO NOT ALLOW CHLORINATED WATER FROM YOUR STORAGE TANK TO
FLOW BACK INTO THE R.O. MEMBRANE.
You may directly “T” your product water line into the tank vent (Refer to the Flow Diagram). This
avoids chlorinated water to back flow from your water tanks into the R.O. membrane and does not
require a new fitting in your tank.
When using a spigot as the taste/test station, be sure you have no shut-off valves in the product water
line. A hand pump style spigot, with a check valve only, is acceptable. If using this type of spigot for
two sources, install a low-pressure check-valve in the product line and “T” it into the existing hand
pump spigot line.
REJECT WATER TUBING/HOSE
Connect the outlet of the pressure control valve on the control panel with a reject thru-hull of your
choice (preferably above the water line).
HARDENER / pH NEUTRALIZER KIT
Install the hardener / pH neutralizer housing at a serviceable location in line with the product water
tubing from the diverter valve on the control panel to the freshwater storage tank. Observe the flow
direction indicated on the housing.
THRU-HULL (not supplied)
The boat’s designated intake thru hull should be located in an area that will always be in the water with
the boat is used under normal running conditions.
A speed boat scoop could be helpful. Installed with the opening facing the bow, it typically generates a
small amount of pressure while moving through the water. It is important not to place the scoop thru-
hull directly forward of a speedometer pickup. It is also wise not to place the intake thru-hull slightly
aft or outboard of a holding tank, head or galley sink overboard discharge.
INSTALLATION INSTRUCTION (OPTIONS)
BOOST PUMP
Install the boost pump with the motor up or sideways in a dry location below the water line, in
between the sea strainer and the pre-filter(s). The intake is at the center of the pump.
Avoid
elbows/ 0 degree fittings in your plumbing. The complete pump head can be turned in case the outlet
direction is not suitable for your installation.
Be sure your electrical wiring for this pump switches off and on at the same time the magnetic clutch
switches off and on, to prevent the pump from being damaged due to dry run.
5MICRON PRE-FILTER HOUSING
Connect the filter housing with the supplied ¾” nylon nipple to the standard filter housing and
reconnect the reinforced vinyl hose. The 5micron cartridge has to be installed as the second filter in
flow direction.
5MICRON PRE FILTER HOUSING WITH LOW PRESSURE GAUGE
The optional 5micron pre filter housing with low pressure gauge has to be installed as a second filter in
flow direction.
FRESHWATER FLUSH SYSTEM
Install the active carbon filter housing at a serviceable location in between your freshwater system
pump and the pre-filter housing(s). Connect one port of the shut off valve to the provided barbed tee.
Connect the two remaining ports of the tee to the outlet of the storage/cleaning valve and to the intake
of the high-pressure pump (refer to the flow diagram). Connect the intake of the active carbon filter
housing to your boat’s pressurized water system.
