What is Reverse Osmosis
Osmosis is the diffusion of two mixable solutions through a semipermeable membrane in such a
manner to equalize their concentration. A water with less salt naturally diffuses into a water with
higher salt.
Sea water or brackish water cannot naturally diffuse through a semipermeable membrane to
provide potable water.
A man-made process, REVERSE OSMOSIS, overcomes this natural phenomenon. By forcing
sea or brackish water (under high pressure) through a semipermeable membrane, potable water can
be realized !

2Process description and system components identification
The watermaker has four main sections:
Prefiltration section where salt water, supplied by the booster pump (A), is filtrated passing through the two
prefilters (B and C). Feed water pressure is taken by the low pressure sensor (E) and shown on the display of the
electric box (Lbar);
High pressure section in which sea water is pressurized by the high-pressure pump (F). The high-pressure sensor
(G), electrically connected to the electric box, shuts down the system automatically if the operating pressure exceeds
the preset level. The unit can be equipped with automatic pressure regulator valve (I) or can be run also in manual
mode and the working pressure adjusted manually by the pressure regulator valve (I) located on top of the
motorized valve. The high-pressure tubes and their fittings require periodic (see MAINTENANCE section).
Salt water (BRINE) discharge section. In this section the brine is discharged. The fresh water is also discharged out
of board if it does not have the drinking-water quality. Through the three-way solenoid valve (N), the electric box
automatically switches the water coming from membranes either to the discharge or to the fresh water tank. The
water quality is checked by the salinity sensor (M). The temperature sensor (M1) compensates the reading
according to temperature. The salinity and temperature sensor require periodic maintenance (see MAINTENANCE
section).
Freshwater section. This is the most important section of the system, the section where the physical process of
reverse osmosis takes place. The main components of this section are the semipermeable membranes which separate
sea water in two flows: one with concentrated salts which goes to the discharge (R) and the other with fresh water
(U) which goes to the fresh water tank. The fresh water flow is taken by the flow sensor (L) before reaching the
three-way solenoid valve (N) and shown on the display. The three-way solenoid valve (N) switches the flow,
depending on its salinity, to the discharge or to the tank. The semipermeable membranes are very sensitive
components and require strict observance and care (see PROTECTION AND CARE OF SEMIPERMEABLE
MEMBRANES in Maintenance section).

3Installation Procedure
3.1 Components supplied by owner
Some plumbing and electric components are to be supplied by owner. These components are listed below:
a) 3/4" or 1” inlet valve with terminal (A2, drawing 1);
b) Tank for produced water (P). The tank should have a safety overflow valve (V1);
c) 3/4" female thread discharge to the sea. A discharge fitting of 3/4 female (Y) is supplied by Tecnicomar where lines
BRINE (R) and UNSAFE WATER (S) are connected (refer to drawing 1);
In case of installation aboard a vessel, the discharge must be installed above the water line.
d) power supply line, protected by an automatic all-pole thermal and differential protection/ disconnection device. The
differential circuit breaker must be set to act with the dissipation current of 30 mA. For setting of the thermal circuit
breaker and for the sizing of the power supply line the values from the POWER REQUIREMENT TABLE should
be respected (ref. Section 9).
3.2 Plumbing connections
CONSIDERATIONS:
Lenght of connection lines: the watermaker will work most efficientely with short plumbing connections. When the
suction line is long the feed pressure decreases. When the discharge line is long the back pressure increases in that
line. There should be no back pressure on the discharge line or on the product line.
Feed water: be sure that the inlet thru-hull fitting is installed in a way that the watermaker receives an uninterrupted
supply of air-free feed water.
Membranes: the membrane vessels must not be exposed to temperature higher than 50°C (122°F) or lower than 5°C
(41°F). For preservation of membrane modules in very cold areas see par. 6.3
For correct installation of SAILOR in compact and modular version:
Connect the SEA WATER INLET (A2) with the T1 side of the manual three-way valve (T) using the supplied hose
of dia. 20 mm.
Connect the outlet of the low pressure pump (A) with the inlet of the prefilters (B).
Connect the Auto-Flushing system (if supplied) to the tee fitting on the prefilters.
Connect the BRINE (R) and UNSFE WATER (S) lines to the discharge connector (Y).
Install the supplied fresh water fitting (V) onto the fresh water tank (P). Connect outlet of three-way solenoid valve
(U line) to the fresh water fitting (V). Be sure that fresh water tank has an overflow valve (V1).
For correct installation of SAILOR in splitted (slim) version (control panel, membranes module, low pressure pump
and prefilters):
Connect the SEA WATER INLET (A2) with the T1 side of the manual three-way valve (T) on the low pressure
pump using the supplied hose of dia. 20 mm.
Connect the outlet of the low pressure pump (A) with the inlet of the prefilters (B).
Connect the Auto-Flushing system (if supplied) to the tee fitting on the prefilters.
Connect outlet of prefilter (C) to inlet of the high pressure pump (F) and to the low pressure gauge (D).
Connect the outlet of the high pressure pump (F) to the first membrane.
Connect the dischrge from membranes to the pressure regulation valve (I) located behind the control panel.
Connect the produced water from mebranes to the flowmeter (L)
Connect the BRINE (R) and UNSFE WATER (S) lines to the discharge connector (Y).
Install the supplied fresh water fitting (V) onto the fresh water tank (P). Connect outlet of three-way solenoid valve
(U line) to the fresh water fitting (V). Be sure that fresh water tank has an overflow valve (V1).

4First Start-up procedure
Before the first start-up it is necessary to check that no component of the system was damaged during transport or
handling; this is especially important for the high-pressure circuit components.
If all steps for the correct installation of the watermaker have been followed (Section 3), the first start-up procedure can
be done:
Be sure that all electrical connections are correctly made.
Open the filters (B) and (C) and fill them with pure non-chlorinated water. Check that filter cartridges are inside.
Re-install the filters.
Open the inlet valve (A2).
Make sure that manual three-way valve (T) is on position T1 (operation).
Open the valves along the discharge line, if installed.
Open the valve on the fresh water tank, if installed.
Switch on the power supply and check that the display is on.
If there is three-phase power supply, press F1 to start the feeding pump
and, from the motor fan side, control the clockwise rotation (opposite the
sense indicated in the pump body).
Push STOP.
Switch on the feeding pump by F1 and operate for 5-10 minutes,
controlling that:
Salty water is discharged (BRINE)
Low pressure gauge indicates steadily over 1 bar.
If there aren’t this two conditions the feeding pump is not correctly primed ( i.e. problems in installation: feeding
pump above the sea cock valve, air inside the system, …), therefore is not allowed to start the high pressure pump.
Push STOP.
Remove the sticker from the high pressure pump cap (F).
Check that the EMERGENCY STOP push-button is not activated (turn clock-wise).
Start the system by pressing START.
If the unit is equipped with a motorized valve to auto-regulate the pressure, we recommend to run and stop the unit
ONLY by the START and STOP keypads. If by chance you have pushed the EMERGENCY STOP red button, we
recommend to unlock the button by turning it counter-clockwise but NOT TO RUN immediately the unit. WAIT AT
LEAST 2 MINUTES BEFORE PUSHING START. This is to prevent the unit from starting when the valve is still
closed and the plant is pressurized which can damage SERIOUSLY the membranes and the motor.
If after about 20 seconds the feed water pressure does not rise, the system shuts down automatically.
WARNING - Do not repeat the start-up more than twice if the system does not start.
Check that no air is sucked in and that there are no water leaks in the whole system.
In case of automatic pressure regulator device
After some minutes of operation, the system pressure (Hbar) gradually increases up to 60 bar. Check the pressure
for a few minutes. If there are any leaks, stop the system by pressing the STOP key. Correct the problem and start
the system again by repeating the above procedure.
In case of manual pressure regulator device
After at least 5 minutes of operation, gradually increase the system pressure by slowly turning the pressure control
valve (I) clockwise. Keep doing it until the reading of the high pressure on the display is 60 bar (850 psi). Check the
pressure for a few minutes. If there are any leaks, stop the system by pressing the STOP key. Correct the problem
and start the system again by repeating the above procedure.
Never operate the watermaker at a pressure exceeding 60 bar (850 PSI)
As soon as the system is pressurized the production of fresh water begins and is monitored by the electronic salinity
control system which will automatically switch the flow to the tank when it is desalinated.

5Routine operation
5.1 Routine operation (c/w automatic pressure regulator device)
After having carried out the first start-up (section 4), the everyday start-up and operation of the watermaker will be
simple and fast.
Follow the START-UP steps listed below:
Open the sea water inlet valve (A2).
Start up the system by pressing START.
Check that the feed water pressure is correct: the low pressure value showed on the display should not get below
30% of the reading as it was with new filter cartridges. If necessary, clean or replace the filter cartridges. The
electric box will automatically shut down the system if the feed water pressure is below the minimum level needed
for the correct operation (0.3 bar).
Prefiltrated, clean sea water is extremely important for correct operation of the watermaker. It is
also a good help to longer life of membranes. We recommend the exclusive use of replacement
cartridges supplied by Tecnicomar.
If the produced water salinity increases, contact the Tecnicomar Service center.
Follow the SHUT DOWN steps for a correct and safe system power-off:
Push STOP.
Switch off the power supply.
Close the sea water inlet (A2).
5.2 Routine operation (c/w manual pressure regulator device)
After having carried out the first start-up (section 4), the everyday start-up and operation of the watermaker will be
simple and fast.
Follow the START-UP steps listed below:
Open the sea water inlet valve (A2).
Make sure that the pressure control valve (I) is open (ignore this point if the unit is equipped with the automatic
pressure regulator device).
Start up the system by pressing START.
Check that the feed water pressure is correct: the low pressure value showed on the display should not get below
30% of the reading as it was with new filter cartridges. If necessary, clean or replace the filter cartridges. The
electric box will automatically shut down the system if the feed water pressure is below the minimum level needed
for the correct operation (0.3 bar).
Prefiltrated, clean sea water is extremmely important for correct operation of the watermaker. It is
also a good help to longer life of membranes. We recommend the exclusive use of replacement

Instructions for the installation, use and maintenance of Tecnicomar watermaker
5-19
If the produced water salinity increases, contact the Tecnicomar Service center.
Follow the SHUT DOWN steps for a correct and safe system power-off:
Depressurize the system by turning the pressure control valve (I) counterclockwise (ignore this point if the unit is
equipped with the automatic pressure regulator device).
Push STOP.
Switch off the power supply.
Close the sea water inlet (A2).
5.3 Manual running mode (c/w automatic pressure regulator device)
In case you need to pressurize the unit manually:
Start procedure
Turn the selector automatic/manual located onto the motorized valve (I) in “manual” position (when the unit is
off).
Start the unit and turn the handle located top of the motorized valve (I) until reading 60 bar on the display (HObar).
Stop procedure
Push STOP and turn back the handle top of the motorized valve (I).
Move back the selector automatic/manual located onto the motorized valve (I) in “automatic” position.
5.4 Operation in low- or high-salinity areas
Tecnicomar watermakers may also operate in areas with unknown feed water salinity, like lake or river waters.
In low-salinity areas the applied operating pressure should be less than 60 bar. In such cases the produced water flow
rate should be taken under control when applying the operating pressure.
The fresh water production must never exceed the system maximum production (refer to system
technical characteristic, Section 9).
5.5 Operation in cold areas
In very cold areas and in high salinity areas there will be a decrease in the fresh water production. In such conditions the
operating pressure must always be kept at 60 bar (850 PSI).
Never operate the watermaker at a pressure exceeding 60 bar (850 PSI)

6Special procedures
6.1 System normal operation.
The watermaker electric box checks continuosly the system operation. The watermaker does not represent any risk for
the user since the electric box automatically checks, by the appropriate sensors, the equipment correct operation.
However the system can operate also in EMERGENCY conditions. In this operation mode the electric box cannot shut
down the system anyway even in case of danger.
It is extremely IMPORTANT that the watermaker is operated in emergency mode only by
personnel trained in matters of electricity. It is also advisable that during the
EMERGENCY operation nobody stay near the watermaker because an unexpected rise
of pressure may cause hosings or fittings explosion. The EMERGENCY STOP breaker is
always active and the system can be powered down at any time by using this switch (the
emergency stop pushbutton is installed on the control panel and is identified by its
mushroom form, red color and the EMERGENCY text).
6.2 Emergency operation
WARNING: HIGH VOLTAGE SHOCK RISK!
DO NOT CARRY OUT THE OPERATIONS DESCRIBED BELOW WITH WET HANDS. DO
NOT TOUCH THE INSIDE PARTS OF THE ELECTRIC BOX.
If there is a problem on the electric box, the system can be operated in EMERGENCY conditions, without the support
of automatic electronic controls. This mode of operation is normally not recommended. Only in cases of extreme
necessity and strictly following the instructions given below it is possible to operate the system.
In case of automatic pressure regulator device
Open the sea water inlet valve (A2).
Switch off the power supply.
Turn the selector automatic/manual located onto the motorized valve
(I) in “manual” position (when the unit is off).
Remove the electric box front panel by unscrewing the four plastic
bolts.
Using an insulated-handle screwdriver bring the switch S1 (fig. 5) in
the ON position.
