4. INSTALLATION
41. PREPARATION
The hull fitting and the hull valve are supplied and installed by the work site.
The sea water feeding hull fitting (EdM) should be placed as low as possible below the water line, in an area always immersed whatever the boat's navigation rate may be.
The hull valve (V0) should be placed on the sea water feeding pipes, as close as possible to the hull fitting.
The reject hull fitting (R) should be placed above the water line.

42. PLACING THE UNIT

- The booster pump should be installed below the water line, as near of the hull valve as possible.
Range YK in kit form
- The filters should be fixed vertically in place, by means of the equipped support.. If necessary, it can be slightly inclined in relation to
the vertical position.
- The HP pump set should be mounted horizontally on a rigid base, by means of its rubber mountings.
- It is allowed to install the R/O module in any position, vertically or horizontally, provided the pressure gauge and the pressure valve
remain a correct accessibility.
HP pump and R/O module are connected together by means of a 1500mm length flexible hose. Sometimes it is necessary to install
them in such a way, that the hose is too short. I this case, HP flexible hose of special length is available as extra.
FUNCTION
Always immersed, it insures continuous sea water feeding of the unit. Not included in the supplies.
Situated near the hull fitting, insures shutting of sea water feeding. Not included in the supplies.
Insures feeding of the unit through the filters.
Contains a washable element, which protects the Booster Pump against the coarsest impurities.
Manual three-way valve allowing to feed the unit from a bucket which contains fresh water or chemical solutions, in order to
rinse or to clean the membranes.
Feeds the filters under positive pressure and sufficient flow. Should be installed below the water line in order to avoid any
intake of air in the circuit.
Contains elements insuring sea water filtering at 20µ and 5µ.
Automatically stops the unit in case of insufficient feed water pressure.
Indicates the sea water feed pressure.
Driven by coupled electric motor, it raises sea water pressure to the required value.
Protects the membranes against high pressure variations.
Automatically stops the unit in case of overpressure in the system.
Made up of pressure-resistant vessels, containing the membranes in which the desalination of sea water is carried out.
Indicates the pressure in the R/O membranes.
Insures adjustment of the pressure in the membranes, conforming to instructions given in Chap.2.
By opening this valve, the valve (2) itself being turning to rinsing position, the unit can be operated in closed circuit on a
bucket containing cleaning solutions. See Chap. 87.
Indicates the flow of water produced by the water maker.
Continuously measures the salinity of the produced water and controls the valve (16) according to this measure.
Electromagnetic 3 -way valve controlled by the salinometer. It automatically directs the produced water towards the tank if the
salinity is correct, or towards discharge to the sea, if it isn't
Collects the concentrated brine produced by the membranes for discharge to the sea..
Situated above the water line, insures brine discharge to the sea . Not included in the supplies.
Insure feeding of the unit with the water or chemical solutions contained in an auxiliary bucket, during the membranes rinsing
and cleaning operations.
Direct the unit discharge towards the auxiliary bucket, thus insuring membranes cleaning in closed circuit.
FUNCTION
Starting up of the unit and indication with an integrated signal lamp.
Stopping of the unit.
Shows the quality level of the produced water with four LED ( green, green, orange, red).
Green LED indicating that the reject valve is in « production » position.
Measures the salinity of the produced water with a cell ; shows the measure with the LED indicator (32) and controls the
diversion valve (16).
Insures the connection between the different electrical control components.
Protection of the electric box.
Indicates the running time of the unit.
Supply of 24VAC current to the control box.
Feeds the booster pump electric motor.
Feeds the HP pump electric motor.
Protection of the booster pump electric motor, in case of overload.
Protection of the HP pump electric motor, in case of overload.
Range YC in compact
form
- The main module should
be bolted on a rigid
horizontal surface.
