(1) The pressure is automatically adjusted, depending on operating conditions (water salinity and temperature).
(2) The nominal capacity is given for a new unit, nominal membranes performances, operating in standard seawater TDS 35000ppm (35g/l) and temperature
25°C. The capacity can vary from +/-15%, according to allowances given by the manufacturers of the membranes.

FUNCTION
Always immersed, it ensures continuous seawater feeding of the unit. Not included in the supplies.
Not take the water on the driving cooling circuit. Place the hull valve (V0) in most farther of the hull
valve ( R ).
Situated near the hull fitting, insures shutting of seawater feeding. Not included in the supplies.
Ensures feeding of the unit through the filter (4).
Manual 3-way valve ensuring feeding of the unit, either with seawater in normal operating, or with the
water or chemical solution contained in a bucket during cleaning or preservation of the membrane.
Contains an element ensuring seawater filtering to protect the booster pump (LP).
Driven by an electric motor, it raises seawater pressure to the required value up to 6 / 9bar. Must be
installed 200mm below the water line.
Contains an element ensuring seawater filtering at 5µ (essential before the membrane).
Indicates the LP pressure.
Increase seawater pressure to produce fresh water through the R/O membrane.
To bleed the system at the first start-up, or after replacement of the filters. Allows operation of the unit
at low pressure when opened for cleaning or preservation operations.
Indicates the HP pressure.
Made up of pressure-resistant vessels, containing the membrane in which the desalination of
seawater is carried out.
By opening this valve, the valve (1) itself being turned to rinsing position, the unit can be operated in
closed circuit on a bucket containing cleaning solution.
Electromagnetic 3-way valve controlled by the salinity cell. It automatically directs the produced water
towards the tanks if the salinity is correct, or towards discharge to the sea, if it isn't.
For dechloration of fresh water of rinsing to preserve the membrane.
Continuously measures the salinity of the produced water, and controls the valve (14) according to
this measure.
Insure automatic rinsing of the desalinator by taking fresh water from the network of water on the boat
in load.
Collects the concentrated brine produced by the membrane for discharge to the sea.
Situated above the water line, ensures brine discharge to the sea. Not included in the supplies.
(avoid installing the reject in front of the entry seawater).
Ensure feeding of the unit with fresh water and chemical solutions stored in a bucket or a holding
tank, during membrane cleaning operations.
Direct the unit discharge towards the auxiliary bucket (after tilt the valve 11), thus ensuring cleaning of
the membranes in a closed loop.
